Sorry for the delayed reply -- it's been a busy week.

Kevin Brooks wrote: snip From DS on the USN has relied increasingly on USAF and foreign land-based tankers, because their own tankers lack the numbers/offload/loiter/drogue stations to allow them to go far inland with large strikes. The USMC has its KC-130s, which are at least dual-point, but they're limited to perhaps 6 a/c in a flight pre-strike, with four preferred, before they meet the law of diminishing returns. A single-point boom tanker is about the same. It's not that the navy can't use their S-3s or F-18E/Fs exclusively, it's just that they're limited in the size/radius of their strikes when they do so. Which is why the USAF will still have the capability of supporting the USN, with both single and dual point refueling. The fact that the 767 won't have that multi-point capability up-front is NOT going to create a critical situation for the USN. But it may be critical for bed-down and other operational issues, and it's definitely inefficient. Besides,who says we're only supporting the USN? In various conflicts we've had help from Canadian and Spanish Hornets, plus the RAF, AMI, KDF, RNAF, Luftwaffe etc. They've helped us with _their_ multi-point tankers on occasion. And that help has been appreciated. But that does not really imply that we have to optimize *all* of our aircraft to perform multi-point refueling right *now*. I never said they _all_ had to be optimized right _now_, but I can see no reason not to buy new tankers set up that way from the start, as our need for drogue tanking is clearly inceasing (cf. the proposed USAF F-35B buy). Given our increasing jointness, it does seem odd that the KC-767 isn't planned to have provision for wing drogues from the get-go. Not necessarily. The USAF is getting to the desperation point in regards to the 135E's--they are either going to have to poop a lot of money to upgrade them (not the wisest choice, given their age and condition), or they have to get a replacement in the air, and rather quickly. The justification for that has always been somewhat questionable. Only a few years ago they were projecting the 135E's fatigue life out 30 or 40 years, although the engines were probably going to need replacement. Let's face it, the 767 deal has more than a little to do with keeping Boeing's 767 line open and people employed. Would it be a good thing to get some newer tankers? Sure. Do we need them right now, because the 135Es are falling apart? That's arguable. Firstly, "only a few years ago" was before we (again) had to surge tanker support for two recent operations--that eats into remaining lifespan (operating hours for the tanker force being about a third higher than they were pre-9/11). Yes, an increase from an average utilization of 300 hours/yr. to 435 hrs/year. Even at the latter rate the KC-135Es have a fatigue lifespan of 82 years (36,000 hrs., vs. 39,000hrs for the KC-135Rs), and they're just a bit over halfway through that. Second, if you are going to replace the engines (and associated controls), you are talking about a sizeable investment (witness the never-ending debate over the wisdom of reengining the B-52's, C-5's, etc.) right there. Then you have to remember that the E models have also not undergone other avionics updates due to their age/limited lifespan remaining, so if you want to keep them around you are going to have to do the whole PACER CRAIG thing, etc. In other words, turn them all into R models--which does not sound like a real wise investment. We don't know that's the case, as we haven't done the assessment. Indeed, the Defense Science Board just came out (see http://www.airforcetimes.com/story.p...25-2904714.php with a report that apparently says that upgrading some Es into Pacer Crag Rs may well be the most cost effective solution, while we take a couple of years to do a proper tanker requirements study. We apparently never finished the one we started in 2001, and we're now talking about doing one that will run from 2004 - 2006. What the DSB has said is that there is no need to imminently replace the Es - we've got time to look at our options. If you google on news and search defense science board tanker you'll come up with several sources that provides sniuppets of detail. The actual report isn't available yet on the DSB website, apparently because it hasn't yet been briefed to Congress. It is beyond argument that the E models are the anchormen when it comes to MC rate (about 78% for the E models, versus 82% for the R models, based upon GAO figures for May 2003). Without reengining, and taking them up to the R standard, this MC rate difference will only grow--it drops below 75% and I'd think the USAF leadership will really start to howl. Corrosion maintenace is another (growing) concern, and it will eat up more and more money as we try to stretch out the E model's lifespan. The corrosion problem is apparently under control. See the URL above. From what I recall of the GAO report, the O&M costs for the Es was averaging $4.6 million a year vs. $3.7 million for the Rs Oddly, even the GAO noted that they recommended that the USAF start paying serious attention to replacing the KC-135 fleet as early as 1996 (of course, in typical GAO style, they have managed to cover their bases in all eventualities, so they can always say, "Told ya so!" regardless of how we proceed...). That last part (quickly) seems to merit a sort-of-spiral approach, to me; get them into service ASAP with the boom and single-point drogue (while still having the 135R's in service, some with the multi-point hoses), and then worry about bringing them up to a higher standard later, when the time-crunch is not so critical. I see it as entirely budget-driven, with the huge bow-wave they've already got going restricting them. Indeed, that was the primary reason for the KC-767 lease rather than buy in the first place. The lease came about because it (a) allowed the USAF to recapitalize the oldest portion of the tanker fleet in the most rapid fashion, and (b) because it was also beneficial to Boeing in terms of keeping the 767 line open. Don't act as if the latter is a "bad" thing--we have paced procurement programs to keep assembly operations going for decades, be it the C-130 or the M-1 tank. Consider how much MORE it would cost to *buy* the 767's if we drag this out through the usual (overly long) procurement cycle, and the line has in the meanwhile shut down; restarting a line is not going to be cheap. Some folks cry that this is a "help out Boeing" deal--I don't agree, at least completely, as it also helps out the USAF in getting timely replacements for the aging KC-135 fleet; and to be honest, even if it *were* more of a "help out Boeing" deal it would not concern me greatly, as I see a necessity in our keeping alive the kind of combined commercial/military transport production capability that we NEED to have, unless you are willing to be 100% reliant upon a foreign provider for our future tanking and heavy transport needs (I for one would hate to see the French government in a position to slow down or stop delivery of such a critical asset merely because they would want to show us they could do it). One of the things I object to is the assumption, without any analysis, that the 767 buy is essential (the DSB says it isn't), or that it's the most cost-effective solution (we don't know). Another thing that worries me about rushing into a 767 buy is that we'll be buying an a/c that is essentially out of production except for the USAF. The KC-135s were bought at the opposite extreme. These a/c are going to last us at least 50 years, so spares are going to be a real problem down the road, as the commercial operators are already starting to look for replacements. Italy and Japan won't have a problem, because they're each only going to buy airframes in the single-digits so they'll be able to buy adequate spares from cannibalised airframes, but the USAF is talking about buying at least 100, possibly with more to come. When the 767 deal was first mooted, it was really the only in-production (US) a/c in the size class available in the proper time frame. That is no longer the case, as the 7E7 will be entering service in 2008 (this is a commercial a/c, and unlike the military, missing production and/or performance guarantees cost the company big bucks). We need to see if it makes more sense to buy 7E7s at the _start_ of their production cycle, rather than 767s at the end of theirs. Which is better suited for the role? Is the extra M0.05 in cruise a major advantage? Does the higher composite content significantly decrease the corrosion issues down the road? How about the 20% better fuel efficiency? Respective runway and ramp space requirements? PFI vs. military? Etc. snip Which KC-10's and KC-135R's will still be serving, you should add. Correct me if I am wrong, but the aircraft that the 767's are destined to replace, the 135E's, do not have the multi-point refueling capability, either, do they? No, they don't, and the 767's will at least be able to refuel both types of refueling systems on the same sortie, and they'll have a proper drogue rather than that ******* afterthought on the end of the boom. OTOH, we're also buying fewer of them than the 135Es they're supposed to replace (differing MC rates obviously play a part). But in big strikes, it's the number of refueling drogues/booms in the air that determine the service rate, and it's silly to have to use (and bed-down) double the number of a/c if we don't need to. That does not necessarily hold true. If the requirement to provide hose/drogue capability in-theater is 8that* important in a given case, you send the KC-10's and multi-point 135R's forward, and use the other aircraft (i.e., these pre-improvement 767's) to handle the usual airbridge su[pport operations into the theater. I think KC-10s are too important as deployment tankers early on in a conflict to use them in the tactical role. After all, that's what we bought them for, precisely so we could get to the Middle East from the US non-stop, if we were refused landing/overflight rights. Let's face it - being on good terms with Portugal (Lajes) and Spain (Moron) has become more important to us than ever. Besides, KC-10s take up a lot of space, and need stronger runways than 135s or 767s (don't know how the 7E7 stacks up), which may limit its deployment options. So what you really seem to be saying is that the 767's, even without initial multi-point capability, offer an improvement to the current level of support that can be afforded to the USN? Yes, they do, but the question remains, are 767s rather than upgraded Es and later 7E7s the best way to go; what's the best mix, what % of tankers need to do which roles, how will the advent of UCAVs affect the need for tankers and the type mix, what effect will USAF F-35 buys have, etc. This needs to be properly studied. snip So what you are saying is that we should delay the program even further than it already has been, so that all of the new aircraft are capable of performing a mission that only a certain portion of the joint force (the USN strikers and whatnot) can receive from them the same level of support...that they can already get from the other aircraft that will be remaining in service? I don't necessarily agree with that analysis (and neither does the USAF, apparently). I'm saying that it makes far more sense now to buy the capability up front that we know we'll be adding down the road, especially since the R&D work is largely being paid for by Italy and Japan, than to add it years from now when we know it's going to be more expensive to do so. Whoah there, hoss. If the R&D is being picked up elsewhere (by virtue of those foreign sales you mention), that advantage does not go away because we dicide not to implement the multi-point system up-front. That R&D effort is still applicable. And you are avoiding the fact that it will slow the delivery timeline if we have to go with this optimization up-front. I'm aware that the R&D will still apply, I'm worried about the materiel costs, which are only going to go up. If we need the capability, then let's just buy it and get the purchase out of the way, instead of paying inflated prices later. If that means we buy a/c at a slower rate (and more refueling pods), good. Good? I disagree. So does the USAF, from what I have read. The DSB doesn't, and Rumsfeld said that he was waiting on a couple of reports, including theirs, before making a decision. We plan to be operating from more austere bases, which tend to be somewhat limited in ramp space, so anything we can do that limits that is a plus. That was indeed one of the USAF's arguments against the A330 -- that it took up too much ramp space while providing no more refueling stations than the 767. They considered the A330's somewhat greater offload irrelevant for the tactical refueling mission; they were concerned with the number of booms/drogues on station while minimizing the ground footprint. If that logic is valid, then buying dual rather than single-point capability is even more valuable as a way of minimizing the ground footprint. See below. In the long run, yes. But is it worth slowing delivery up-front even further than it already has been slowed? According to the DSB, we have the time. snip Another thought--the USN has been buying C-40's of late--if they are so keenly worried about their refueling capability, why did they never think about including a secondary tanker role for that aircraft, or that class of aircraft, such that they could help themselves out? Probably not, because that would have required them to spend their own part of the budget pie...much better to have the USAF spend their money, eh? I'm sure they think so. OTOH, FAIK the USAF would have fought against any such proposal with tooth and nail. The navy has in the past considered buying their own land-based tanker fleet, but ISTR that SAC (at the time) in effect said "over our dead body." IIRR the Tradewind was an attempt to get around that; after all, the USAF could hardly complain about seaplanes. I imagine AMC would act similarly proprietarily today, but the point (to me, at least) isn't which service provides the capability, but that it be provided. But they oddly don't have a problem with the USMC buying C-130J's to augment their current tanker fleet. Of course not, because a KC-130 (any flavor) clearly isn't a replacement for a jet tanker. It meets USMC needs for a STOL tanker/transport that can also refuel helos (AFSOC too), and for countries that also operate C-130s it's a relatively cheap, easy way to get some A/A tanking capability; it's certainly better than nothing, as Argentina can attest. But it's a relatively inefficient tanker for fast jets, lacking range, speed, cruise altitude, and offload capability. Personally, I doubt the USAF would have put up a fight if the USN had said they wanted to incorporate a secondary refueling capability in their C-40B's; just as the USN has been strangely silent over the USAF talking about recreating an in-house stand-off jamming capability. There is no way in hell that the USN would pay the R&D NRE for a tanker mod for their C-40s, with all their other needs. snip area of general agreement Clearly you can get a force of tankers in theater a lot faster than a force of tankers PLUS a force of fighters and all their support. Can you? I am not sure about that (note how quickly we got the lead squadrons of the 1st TFW into Saudi Arabia in 1990), especially since getting all of those tankers into the theater is only going to do you some good if the fuel for them to haul is also present, or readily available, at that operating location. The 1st TFW had an A/A role, IIRR deployed with a full loadout of missiles on thea/c and could fairly easily bring an adequate number of reloads with them, or fly them in later. A/G ordnance can be a very different matter, although PGMs help that aspect. I can't remember if it was the A-10s or F-15Es, but in one of Smallwood's books (I think), aircrews described just how limited their A/G ordnance options were right after they deployed. Fuel, OTOH, is relatively available anywhere a commercial airliner is able to operate from. Maybe you need to haul in JP-5/8 for the tactical a/c, but the tankers themselves should be able to operate on Jet A/A-1. As to fuel availability, I was referring to the ready availability of the JP-8 in bulk form--and it won't necessarily be there (always) in the quantity you want at those "remote" bases you refer to unless we haul it in ourselves. JP-5 presumably, if they're refueling navy a/c that are operating from CVs. At least, that's my understanding, but maybe some of the KC-135 people here can comment. Usually meaning by ship. A second ship can haul quite a few pieces of ordnance, right? Sure, but getting fuel to an airfield is relatively easy (pipelines); moving ordnance tends to require a lot more handling and surface transport. If you are tied to getting basic resources into the TO, you might as well be "in for a penny, in for a pound". And yes, the use of PGM's has resulted in a drastic reduction in the volume of ordnance that has to be transported into the TO (ISTR Franks noting that during OEF we were effectively engaging as many targets per day as we did during ODS, with about 10% of the average daily sortie rate compared to the earlier conflict). As we move towards use of the 500 pound JDAM, and even moreso the SDB, the need for ordnance (in terms of volume/weight) will shrivel even further. PGMs certainly help, but the problem is the variety of A/G ordnance that may be required. A/A, there's two types of missiles and gun ammo. A/G, even with PGMs there's lots of different kinds, and the usage rates are far higher. How much more trouble is it for the USAF to put a force that could easily surpass the per-day delivered-tonnage capability of a CVSG (given your premise that the CVN is having to operate from extended range itself)? If they've got sufficient time to get set up in advance, fine, but crises often don't provide that kind of time. We've been lucky that most of our wars in the past decade and a half (OAF somewhat excepted) have given us some lead time to get ready. I'd posit that using the basing options we already have in-hand (Guam, Diego Garcia, Fairford, and CONUS), the B-1, B-52, and B-2 can acheive this pretty much anywhere in the world *now*. In that case, let's dump the fighters altogether ;-) Three or four B-1B's or B-52's alone can acheive that. And provided you're willing to send them in without any SEAD at the start of the war, and multi-hour cycle times are no problem, great. I was playing devils advocate a bit here, but if you areally want to get down to details, yeah, they could still provide a reasonable option. Use of ALCM's to target IADS nodes/assets during the initial phase, with the pending "electric" B-52 providing standoff jamming support, B-2's doing their thing, and then as we start taking down the defenses, we can move a bit closer and start using the other standoff systems (i.e., JASSM). Given the range we saw the F-16's operate at during OEF, it would not be beyond the realm of possibility for the F-15C's and E's to get into the ballgame at long range, either (if they had to). As I have said a couple of times, I do see a use for the CVN's--but barking that they just *have* to have every tanker in the USAF at their beck-and-call does not do much to support the argument that they are such a critical resource, does it? No one (or at least, not I) is claiming that they every USAF tanker has to be available to support the USN, but clearly, an increase is required. IIRR, the GAO report stated we used 150 KC-135s in OAF and OIF; given the large percentage of USN/Marine plus allied sorties in both of those ops, having at best only 40 KC-135s with dual point drogues seems to be inadequate.However, if the tanker requirements study says we don't need more, I'll accept it, but the study needs to be _done_. OEF demonstrated the use of both F-15E's and F-16's in conducting pretty long range strike operations (from the PG around Iran, up to Afghanistan and back again, at greater range than the CVN-based strikers were enduring). Sure did. Using those USAF tankers with booms to maximise the transfer rate. And it helped that we were already set up in the area flying Southern Watch sorties. But we're not there now, although we do still have some presence in the 'Stans, IIRC. And are getting ready to relocate our NATO-assigned assets further east, too, to places like maybe Hungary and Rumania, etc. In the Pacific we have Guam, the ROK bases, Okinawa. Diego Garcia in the IO is the one that is truly the most limited in terms of ramp space, but the bases in the -stans you mention make it a bit less critical than has been the case in the past. The $64 million question being whether those bases will be available to us when we need them. Last I checked there'll all in muslim countries with regimes that are more or less unstable. Given our current unpopularity in the muslim world, I don't think we should count on such bases being available. snip Should we can the CVN's? No, of course not. But they can continue to operate a few more years with the support of KC-135R's and KC-10's without HAVING to have the 767's *optimized* for their very own use. Provided we have sufficient space for all those tanker a/c in theater, fine, but it's still wasteful to use two a/c and crews to do the job of one. Of course, if you're cycling flights of two constantly through the tankers, no big deal, but gorilla packages are another matter. And we may well need to help tank our allies (assuming we have any). Many of them are buying their own multi-point drogue tankers now, which helps both of us if they're along for the ride. That last bit is true. But I think you may be forgetting that during contingency operations we tend to have to operate a number of tanker tracks a long way from the TO (i.e., the Atlantic air-bridge, or a Pacific version, depending upon where the TO is), so those 767's could be a major contributor without even having to enter the local airspace. The real issue is how long we can drag out the 135E fleet; there are 131 of them remaining in service now, with engines that were stripped from old commercial transports some fifteen or twenty years ago as an "interim" fix, corrosion concerns, and obscelescent avionics. Their MC rate can only really continue to drop, which is why yes, we can replace 131 aircraft with 100 newer aircraft and come out in pretty good shape. Or it might make sense to upgrade them all to 135R/Pacer Crag; I read one quote somewhere of the cost savings going that route compared to the 767 buy -- AIR it was a couple of billion dollars over the life of the deal. But that all needs to be studied so we know. Do we have the time available to dally around with optimizing the 767 in all manners before we order them (and run the very real risk of seeing the line shut down in the meantime), or do we take the money we have now and order the first 40 (which is the number the USAF has tossed about as the first firm order volume) with the lesser hose/drogue capability, and then implement the multi-point system on the following aircraft, with the originals being upgraded at a later date? I see the latter as an option that makes as much, if not more, sense than the former. As I've pointed out above, I think an even more fundamental question is should we be buying the 767 at all, rather than some other option. The 767 lease is looking more and more like roadkill, so it may be moot. However, even if we decided to go the 767 route, there's no reason why we couldn't buy 35 of them (or whatever the $ work out to) with wing drogues, rather than 40 without. Guy |

As I pointed out in my reply to Kevin, a KC-130 is a poor choice for a pure jet tanker, if you don't need STOL or helo refueling capability (and the navy doesn't). Can a KC-767 refuel a KC-130J? AFAIK (don't quote me) the KC-130Js don't have probes or receptacles. There's no technical reason why they couldn't have them, and a KC-767/KC-130J refueling would presumably be easier than the Victor/probed C-130K hookups during the Falklands war; the 767 shouldbe able to fly slower than a Victor, and the (K)C-130J is faster than the earlier models.

The USMC has its KC-130s, which are at least dual-point, but they're limited to perhaps 6 a/c in a flight pre-strike, with four preferred, before they meet the law of diminishing returns. A single-point boom tanker is about the same. It's not that the navy can't use their S-3s or F-18E/Fs exclusively, it's just that they're limited in the size/radius of their strikes when they do so. Which is why the USAF will still have the capability of supporting the USN, with both single and dual point refueling. The fact that the 767 won't have that multi-point capability up-front is NOT going to create a critical situation for the USN. But it may be critical for bed-down and other operational issues, and it's definitely inefficient. Besides,who says we're only supporting the USN? In various conflicts we've had help from Canadian and Spanish Hornets, plus the RAF, AMI, KDF, RNAF, Luftwaffe etc. They've helped us with _their_ multi-point tankers on occasion. And that help has been appreciated. But that does not really imply that we have to optimize *all* of our aircraft to perform multi-point refueling right *now*. I never said they _all_ had to be optimized right _now_, but I can see no reason not to buy new tankers set up that way from the start, as our need for drogue tanking is clearly inceasing (cf. the proposed USAF F-35B buy). That reason would be (another) delay in delivery. Why do you think it will be such a major fiasco if the first forty 767's delivered come in without the multi-point capability? IIRC the first contract is projected to cover that number of delivereies. Letting a spiral handle the multi-point capability in the subsequent 60 aircraft is not acceptable? Given our increasing jointness, it does seem odd that the KC-767 isn't planned to have provision for wing drogues from the get-go. Not necessarily. The USAF is getting to the desperation point in regards to the 135E's--they are either going to have to poop a lot of money to upgrade them (not the wisest choice, given their age and condition), or they have to get a replacement in the air, and rather quickly. The justification for that has always been somewhat questionable. Only a few years ago they were projecting the 135E's fatigue life out 30 or 40 years, although the engines were probably going to need replacement. Let's face it, the 767 deal has more than a little to do with keeping Boeing's 767 line open and people employed. Would it be a good thing to get some newer tankers? Sure. Do we need them right now, because the 135Es are falling apart? That's arguable. Firstly, "only a few years ago" was before we (again) had to surge tanker support for two recent operations--that eats into remaining lifespan (operating hours for the tanker force being about a third higher than they were pre-9/11). Yes, an increase from an average utilization of 300 hours/yr. to 435 hrs/year. Even at the latter rate the KC-135Es have a fatigue lifespan of 82 years (36,000 hrs., vs. 39,000hrs for the KC-135Rs), and they're just a bit over halfway through that. You are forgetting the corrosion problems with the E models--corrosion tends to reduce fatigue life, too, IIRC from my long-ago materials science classes... It sounds to me like the only way you are going to get that long a life from the E's would be if you also replaced some structural components (meaning you are going even further than the old R model mods, IIRC). Second, if you are going to replace the engines (and associated controls), you are talking about a sizeable investment (witness the never-ending debate over the wisdom of reengining the B-52's, C-5's, etc.) right there. Then you have to remember that the E models have also not undergone other avionics updates due to their age/limited lifespan remaining, so if you want to keep them around you are going to have to do the whole PACER CRAIG thing, etc. In other words, turn them all into R models--which does not sound like a real wise investment. We don't know that's the case, as we haven't done the assessment. Indeed, the Defense Science Board just came out (see http://www.airforcetimes.com/story.p...25-2904714.php with a report that apparently says that upgrading some Es into Pacer Crag Rs may well be the most cost effective solution, while we take a couple of years to do a proper tanker requirements study. We apparently never finished the one we started in 2001, and we're now talking about doing one that will run from 2004 - 2006. What the DSB has said is that there is no need to imminently replace the Es - we've got time to look at our options. If you google on news and search defense science board tanker you'll come up with several sources that provides sniuppets of detail. Th e actual report isn't available yet on the DSB website, apparently because it hasn't yet been briefed to Congress. Wait a second--spend *more* money on trying to upgrade E's, while doing *another* study to determine if/when/how we replace the E's? That sounds like a fine...bureaucratic solution? Even the GAO was saying in the 1990's that the USAF needed to get off its duff and start planning the replacement of the KC-135E fleet. Studies are great--unfortunately, they have a tendancy of becoming an ends-unto-themselves. We have a good proposal that the USAF has supported--it puts new airframes into the mission much more quickly than if we follow the "usual" method of purchasing new aircraft (of course, you could use the F/A-22 or F-35 model...which would mean if we started that new study right now, we might plan on seeing some new tankers around what...2015 at best?), and it takes advantage of an existing excess production capability/inventory at the only US company currently building aircraft of that class--sounds like a good plan to me. It is beyond argument that the E models are the anchormen when it comes to MC rate (about 78% for the E models, versus 82% for the R models, based upon GAO figures for May 2003). Without reengining, and taking them up to the R standard, this MC rate difference will only grow--it drops below 75% and I'd think the USAF leadership will really start to howl. Corrosion maintenace is another (growing) concern, and it will eat up more and more money as we try to stretch out the E model's lifespan. The corrosion problem is apparently under control. See the URL above. From what I recall of the GAO report, the O&M costs for the Es was averaging $4.6 million a year vs. $3.7 million for the Rs That is an additional $130 million bucks each *year* in operating cost (not exactly chump-change...but even that is a "lowball" figure...). What would be the operating cost of the 767? Less than the 135R (two engines versus four, better fuel economy, more maintenance friendly subsystems, less likelihood of inspection-and-repair work, more stringent (and more frequent) inspections, etc.), that is for sure. So your operating cost per year differential measured against the 767 is going to be greater. Add in the cost of bringing those E's to a full PACER CRAIG R model level, and the cost is going to be significant, to say the least. Not a wise investment plan, IMO. If you managed your personal auto program in this manner, then you would still be driving (only--no newer cars allowed) a 1960's era car, and one which you had paid to drop new engines in, along with paying to modify the emissions system to keep it in compliance (like the noise requirements the KC-135's face), and here in 2004 you would be saying that instead of buying a new vehicle, you'd be better off paying to essentially completely rebuild the one you have and drop *another* new engine in it, along with updating the other systems in the dash, maybe a new trannie to be compatible with that new engine, etc. I don't think you would endorse such a plan (I made the mistake once of trying to extend the life of a noble little Nissan pick-up at the 170K point by dropping a *used* engine in it, and that was *not* cheap--and I found that within 10K more miles I was *had* to break down and buy a new vehicle). As to corrosion, in March 2003 the USAF's Deputy C/S for Installations/Logistics testified before Congress: "Within the air refueling fleet, the KC-135E-models have experienced the most maintenance and corrosion problems and are more costly to maintain. With an average aircraft age of 43 years, the KC-135E fleet is the oldest combat weapon system in the Air Force inventory. It is also the oldest large fleet of heavy jet aircraft in aviation history...The second critical measurement that defines aircraft life is physical age. In this fleet, corrosion is a function of age. Accurately predicting the extent of corrosion is difficult and this lack of predictability severely limits the ability to efficiently sustain aging fleets...the KC-135 is particularly challenging since its 1950s design, materials, and construction did not consider corrosion prevention measures...The most critical KC-135 tanker metric is age, and the most pressing KC-135 problems are corrosion and stress corrosion cracking-both age related. Stress corrosion cracking is one of the most difficult structural failures to predict." Are you saying that all of these problems have been solved since that date? Oddly, even the GAO noted that they recommended that the USAF start paying serious attention to replacing the KC-135 fleet as early as 1996 (of course, in typical GAO style, they have managed to cover their bases in all eventualities, so they can always say, "Told ya so!" regardless of how we proceed...). That last part (quickly) seems to merit a sort-of-spiral approach, to me; get them into service ASAP with the boom and single-point drogue (while still having the 135R's in service, some with the multi-point hoses), and then worry about bringing them up to a higher standard later, when the time-crunch is not so critical. I see it as entirely budget-driven, with the huge bow-wave they've already got going restricting them. Indeed, that was the primary reason for the KC-767 lease rather than buy in the first place. The lease came about because it (a) allowed the USAF to recapitalize the oldest portion of the tanker fleet in the most rapid fashion, and (b) because it was also beneficial to Boeing in terms of keeping the 767 line open. Don't act as if the latter is a "bad" thing--we have paced procurement programs to keep assembly operations going for decades, be it the C-130 or the M-1 tank. Consider how much MORE it would cost to *buy* the 767's if we drag this out through the usual (overly long) procurement cycle, and the line has in the meanwhile shut down; restarting a line is not going to be cheap. Some folks cry that this is a "help out Boeing" deal--I don't agree, at least completely, as it also helps out the USAF in getting timely replacements for the aging KC-135 fleet; and to be honest, even if it *were* more of a "help out Boeing" deal it would not concern me greatly, as I see a necessity in our keeping alive the kind of combined commercial/military transport production capability that we NEED to have, unless you are willing to be 100% reliant upon a foreign provider for our future tanking and heavy transport needs (I for one would hate to see the French government in a position to slow down or stop delivery of such a critical asset merely because they would want to show us they could do it). One of the things I object to is the assumption, without any analysis, that the 767 buy is essential (the DSB says it isn't), Well, the DSB also says the corrosion problem is something we can easily discount, and has apparently decided that *outsourcing* the tanker mission, or buying second-hand aircraft, is the way to go. Outsourcing may be great for the RAF, etc., but the USAF is another story, IMO. Then there is the "spend the money on already used aircraft" approach--wonderful! As if tossing more money down the O&M pit for the E model is not enough, we should take the money we have and buy older airframes than we can afford? (And yes, we can afford new tankers under the current deal being offered) or that it's the most cost-effective solution (we don't know). Another thing that worries me about rushing into a 767 buy is that we'll be buying an a/c that is essentially out of production except for the USAF. The KC-135s were bought at the opposite extreme. These a/c are going to last us at least 50 years, so spares are going to be a real problem down the road, as the commercial operators are already starting to look for replacements. Italy and Japan won't have a problem, because they're each only going to buy airframes in the single-digits so they'll be able to buy adequate spares from cannibalised airframes, but the USAF is talking about buying at least 100, possibly with more to come. The biggest things you have to buy spares for are the avionics (which are more plug-and-play than they were in the 135 era), and engine related systems. There are a lot of 767's that will remain in service in the civilian sector for decades to come--they will need spares too, and in the end they become another source for spares for the KC version. I don't see this as a deal-breaker. When the 767 deal was first mooted, it was really the only in-production (US) a/c in the size class available in the proper time frame. That is no longer the case, as the 7E7 will be entering service in 2008 (this is a commercial a/c, and unlike the military, missing production and/or performance guarantees cost the company big bucks). We need to see if it makes more sense to buy 7E7s at the _start_ of their production cycle, rather than 767s at the end of theirs. Which is better suited for the role? Is the extra M0.05 in cruise a major advantage? Not likely. Does the higher composite content significantly decrease the corrosion issues down the road? Maybe, but doubtfull, as corrosion awareness was better incorporated into the 767 manufacture than it was in the 135. How about the 20% better fuel efficiency? Sounds good, but then again you have to examine the interval between the time the 767 would be available and the (elsewhere not mentioned, AFAIK) 7E7 tanker version (expect what, a five or six year period at best before the first tanker 7E7 could be available?)...I'll be kind and use a five year period, at 131 E models costing maybe $2 million each more per year in operating costs than the 767, that works out to around $1.3 billion in extra operating costs? That is a hell of a lot of gas... Respective runway and ramp space requirements? PFI vs. military? Etc. Lose the outsourcing option from the get-go, IMO. Won't work for an organization with the scope of tanking requirements that the USAF has. snip Which KC-10's and KC-135R's will still be serving, you should add. Correct me if I am wrong, but the aircraft that the 767's are destined to replace, the 135E's, do not have the multi-point refueling capability, either, do they? No, they don't, and the 767's will at least be able to refuel both types of refueling systems on the same sortie, and they'll have a proper drogue rather than that ******* afterthought on the end of the boom. OTOH, we're also buying fewer of them than the 135Es they're supposed to replace (differing MC rates obviously play a part). But in big strikes, it's the number of refueling drogues/booms in the air that determine the service rate, and it's silly to have to use (and bed-down) double the number of a/c if we don't need to. That does not necessarily hold true. If the requirement to provide hose/drogue capability in-theater is 8that* important in a given case, you send the KC-10's and multi-point 135R's forward, and use the other aircraft (i.e., these pre-improvement 767's) to handle the usual airbridge su[pport operations into the theater. I think KC-10s are too important as deployment tankers early on in a conflict to use them in the tactical role. After all, that's what we bought them for, precisely so we could get to the Middle East from the US non-stop, if we were refused landing/overflight rights. Let's face it - being on good terms with Portugal (Lajes) and Spain (Moron) has become more important to us than ever. Besides, KC-10s take up a lot of space, and need stronger runways than 135s or 767s (don't know how the 7E7 stacks up), which may limit its deployment options. I said, "If the requirement to provide hose/drogue capability in-theater is *that* important". We have the capability of providing substantial hose/drogue capability if we have to--if we really need more, then buy more kits for the existing R's. No matter how you cut it, the decision to not initially provide multi-point capability in the first forty 767's is not going to be a critical, or even serious, failure in terms of our operational capability. So what you really seem to be saying is that the 767's, even without initial multi-point capability, offer an improvement to the current level of support that can be afforded to the USN? Yes, they do, but the question remains, are 767s rather than upgraded Es and later 7E7s the best way to go; what's the best mix, what % of tankers need to do which roles, how will the advent of UCAVs affect the need for tankers and the type mix, what effect will USAF F-35 buys have, etc. This needs to be properly studied. Again with the neverending studies? :-) snip So what you are saying is that we should delay the program even further than it already has been, so that all of the new aircraft are capable of performing a mission that only a certain portion of the joint force (the USN strikers and whatnot) can receive from them the same level of support...that they can already get from the other aircraft that will be remaining in service? I don't necessarily agree with that analysis (and neither does the USAF, apparently). I'm saying that it makes far more sense now to buy the capability up front that we know we'll be adding down the road, especially since the R&D work is largely being paid for by Italy and Japan, than to add it years from now when we know it's going to be more expensive to do so. Whoah there, hoss. If the R&D is being picked up elsewhere (by virtue of those foreign sales you mention), that advantage does not go away because we dicide not to implement the multi-point system up-front. That R&D effort is still applicable. And you are avoiding the fact that it will slow the delivery timeline if we have to go with this optimization up-front. I'm aware that the R&D will still apply, I'm worried about the materiel costs, which are only going to go up. If we need the capability, then let's just buy it and get the purchase out of the way, instead of paying inflated prices later. Even if it delays entry further, meaning you are also going to be paying that higher O&M cost for the remaining E's even longer...? If that means we buy a/c at a slower rate (and more refueling pods), good. Good? I disagree. So does the USAF, from what I have read. The DSB doesn't, and Rumsfeld said that he was waiting on a couple of reports, including theirs, before making a decision. I am not as impressed with the summary of the DSB report as you are (but then again, I tend to weigh the advice of the folks actually tasked to fly the missions a bit more than I do the DSB, GAO, etc). We plan to be operating from more austere bases, which tend to be somewhat limited in ramp space, so anything we can do that limits that is a plus. That was indeed one of the USAF's arguments against the A330 -- that it took up too much ramp space while providing no more refueling stations than the 767. They considered the A330's somewhat greater offload irrelevant for the tactical refueling mission; they were concerned with the number of booms/drogues on station while minimizing the ground footprint. If that logic is valid, then buying dual rather than single-point capability is even more valuable as a way of minimizing the ground footprint. See below. In the long run, yes. But is it worth slowing delivery up-front even further than it already has been slowed? According to the DSB, we have the time. The DSB that claims, contrary to what the USAF LTG testified last year, that the corrosion problem is readily in-hand...? And thinks out-sourcing tanker requirements is a fine idea? I am not buying into either, at this point. snip Another thought--the USN has been buying C-40's of late--if they are so keenly worried about their refueling capability, why did they never think about including a secondary tanker role for that aircraft, or that class of aircraft, such that they could help themselves out? Probably not, because that would have required them to spend their own part of the budget pie...much better to have the USAF spend their money, eh? I'm sure they think so. OTOH, FAIK the USAF would have fought against any such proposal with tooth and nail. The navy has in the past considered buying their own land-based tanker fleet, but ISTR that SAC (at the time) in effect said "over our dead body." IIRR the Tradewind was an attempt to get around that; after all, the USAF could hardly complain about seaplanes. I imagine AMC would act similarly proprietarily today, but the point (to me, at least) isn't which service provides the capability, but that it be provided. But they oddly don't have a problem with the USMC buying C-130J's to augment their current tanker fleet. Of course not, because a KC-130 (any flavor) clearly isn't a replacement for a jet tanker. It meets USMC needs for a STOL tanker/transport that can also refuel helos (AFSOC too), and for countries that also operate C-130s it's a relatively cheap, easy way to get some A/A tanking capability; it's certainly better than nothing, as Argentina can attest. But it's a relatively inefficient tanker for fast jets, lacking range, speed, cruise altitude, and offload capability. I remain unconvinced that AMC would throw a hissy fit if the USN wanted to include a secondary tanking capability to its C-40B's. Personally, I doubt the USAF would have put up a fight if the USN had said they wanted to incorporate a secondary refueling capability in their C-40B's; just as the USN has been strangely silent over the USAF talking about recreating an in-house stand-off jamming capability. There is no way in hell that the USN would pay the R&D NRE for a tanker mod for their C-40s, with all their other needs. Exactly. So the lack of multi-point refuelers must not be such a critical one, eh? snip area of general agreement Clearly you can get a force of tankers in theater a lot faster than a force of tankers PLUS a force of fighters and all their support. Can you? I am not sure about that (note how quickly we got the lead squadrons of the 1st TFW into Saudi Arabia in 1990), especially since getting all of those tankers into the theater is only going to do you some good if the fuel for them to haul is also present, or readily available, at that operating location. The 1st TFW had an A/A role, IIRR deployed with a full loadout of missiles on thea/c and could fairly easily bring an adequate number of reloads with them, or fly them in later. A/G ordnance can be a very different matter, although PGMs help that aspect. I can't remember if it was the A-10s or F-15Es, but in one of Smallwood's books (I think), aircrews described just how limited their A/G ordnance options were right after they deployed. Fuel, OTOH, is relatively available anywhere a commercial airliner is able to operate from. Maybe you need to haul in JP-5/8 for the tactical a/c, but the tankers themselves should be able to operate on Jet A/A-1. As to fuel availability, I was referring to the ready availability of the JP-8 in bulk form--and it won't necessarily be there (always) in the quantity you want at those "remote" bases you refer to unless we haul it in ourselves. JP-5 presumably, if they're refueling navy a/c that are operating from CVs. At least, that's my understanding, but maybe some of the KC-135 people here can comment. I thought we had standardized on JP-8 across the force--ISTR this came up before, but I can't remember the final outcome. Regardless, be it JP-5 or JP-8, you can't count on it being available in a remote operating location, in the volume required, unless you plan on being able to haul it in yourself. Usually meaning by ship. A second ship can haul quite a few pieces of ordnance, right? Sure, but getting fuel to an airfield is relatively easy (pipelines); moving ordnance tends to require a lot more handling and surface transport. Lots of trucks available for lease out there in the world, even in a lot of "remote" areas (any remote are having a pipeline capability likely has a decent truck inventory available in the general area)--or you could use a transportation company (60 line haul tractors and 120 40-ton trailers) from the Army (one of our TC companies that was attached to my old BN HHD did exactly that to support B-52 operations out of Saudi Arabia during ODS). If none of this is doable in your opinion, then IMO you have just shot your "gotta have multi-point capability" in the foot as well, since it would mean that we can't plan on being able to operate the tankers within range of the receivers in the first place. If you are tied to getting basic resources into the TO, you might as well be "in for a penny, in for a pound". And yes, the use of PGM's has resulted in a drastic reduction in the volume of ordnance that has to be transported into the TO (ISTR Franks noting that during OEF we were effectively engaging as many targets per day as we did during ODS, with about 10% of the average daily sortie rate compared to the earlier conflict). As we move towards use of the 500 pound JDAM, and even moreso the SDB, the need for ordnance (in terms of volume/weight) will shrivel even further. PGMs certainly help, but the problem is the variety of A/G ordnance that may be required. A/A, there's two types of missiles and gun ammo. A/G, even with PGMs there's lots of different kinds, and the usage rates are far higher. I'd think if we have the ability to provide both categories of support within the confines of a CVN and supporting TAKO (isn't that the acronym?) for the assualt predicated, we also have the ability of transporting the same quantity of fuel and ammo to an airfield on dry land. The increasing use of PGM's even makes it a realistic option to deliver ordnance to the base by air--something that was unrealistic in the dumb-bomb age (witness the poor ability to do so over The Hump for the B-29's trying to operate out of China during WWII). How much more trouble is it for the USAF to put a force that could easily surpass the per-day delivered-tonnage capability of a CVSG (given your premise that the CVN is having to operate from extended range itself)? If they've got sufficient time to get set up in advance, fine, but crises often don't provide that kind of time. We've been lucky that most of our wars in the past decade and a half (OAF somewhat excepted) have given us some lead time to get ready. I'd posit that using the basing options we already have in-hand (Guam, Diego Garcia, Fairford, and CONUS), the B-1, B-52, and B-2 can acheive this pretty much anywhere in the world *now*. In that case, let's dump the fighters altogether ;-) No, but consider maybe the option of letting the CVN provide only the fighter and EW support (both requiring less tanking support than if they had to provide the complete strike package), and you acheive even greater tonnage of ordnance delivered per strike, and reduce that hose/drogue requirement to boot... :-) Three or four B-1B's or B-52's alone can acheive that. And provided you're willing to send them in without any SEAD at the start of the war, and multi-hour cycle times are no problem, great. I was playing devils advocate a bit here, but if you areally want to get down to details, yeah, they could still provide a reasonable option. Use of ALCM's to target IADS nodes/assets during the initial phase, with the pending "electric" B-52 providing standoff jamming support, B-2's doing their thing, and then as we start taking down the defenses, we can move a bit closer and start using the other standoff systems (i.e., JASSM). Given the range we saw the F-16's operate at during OEF, it would not be beyond the realm of possibility for the F-15C's and E's to get into the ballgame at long range, either (if they had to). As I have said a couple of times, I do see a use for the CVN's--but barking that they just *have* to have every tanker in the USAF at their beck-and-call does not do much to support the argument that they are such a critical resource, does it? No one (or at least, not I) is claiming that they every USAF tanker has to be available to support the USN, but clearly, an increase is required. IIRR, the GAO report stated we used 150 KC-135s in OAF and OIF; given the large percentage of USN/Marine plus allied sorties in both of those ops, having at best only 40 KC-135s with dual point drogues seems to be inadequate.However, if the tanker requirements study says we don't need more, I'll accept it, but the study needs to be _done_. Then your cheapest, and quickest, solution goes back to merely buying more multi-point kits for use by additional 135R's. OEF demonstrated the use of both F-15E's and F-16's in conducting pretty long range strike operations (from the PG around Iran, up to Afghanistan and back again, at greater range than the CVN-based strikers were enduring). Sure did. Using those USAF tankers with booms to maximise the transfer rate. And it helped that we were already set up in the area flying Southern Watch sorties. But we're not there now, although we do still have some presence in the 'Stans, IIRC. And are getting ready to relocate our NATO-assigned assets further east, too, to places like maybe Hungary and Rumania, etc. In the Pacific we have Guam, the ROK bases, Okinawa. Diego Garcia in the IO is the one that is truly the most limited in terms of ramp space, but the bases in the -stans you mention make it a bit less critical than has been the case in the past. The $64 million question being whether those bases will be available to us when we need them. Last I checked there'll all in muslim countries with regimes that are more or less unstable. Given our current unpopularity in the muslim world, I don't think we should count on such bases being available. Then we adjust, and we have the CVN's as insurance--with those additional modified R models, if needed. snip Should we can the CVN's? No, of course not. But they can continue to operate a few more years with the support of KC-135R's and KC-10's without HAVING to have the 767's *optimized* for their very own use. Provided we have sufficient space for all those tanker a/c in theater, fine, but it's still wasteful to use two a/c and crews to do the job of one. Of course, if you're cycling flights of two constantly through the tankers, no big deal, but gorilla packages are another matter. And we may well need to help tank our allies (assuming we have any). Many of them are buying their own multi-point drogue tankers now, which helps both of us if they're along for the ride. That last bit is true. But I think you may be forgetting that during contingency operations we tend to have to operate a number of tanker tracks a long way from the TO (i.e., the Atlantic air-bridge, or a Pacific version, depending upon where the TO is), so those 767's could be a major contributor without even having to enter the local airspace. The real issue is how long we can drag out the 135E fleet; there are 131 of them remaining in service now, with engines that were stripped from old commercial transports some fifteen or twenty years ago as an "interim" fix, corrosion concerns, and obscelescent avionics. Their MC rate can only really continue to drop, which is why yes, we can replace 131 aircraft with 100 newer aircraft and come out in pretty good shape. Or it might make sense to upgrade them all to 135R/Pacer Crag; I read one quote somewhere of the cost savings going that route compared to the 767 buy -- AIR it was a couple of billion dollars over the life of the deal. But that all needs to be studied so we know. Argh! More study? Hell, just go ahead and plunk down the money and make them all R's--we'll continue to pay the higher operating cost (even the R is going to cost more to operate than the 767) for the next forty years--unless wings start falling off, or the operating budget gets cut (not like that has not happened, and rather recently (1990's) too), etc. Personally, I don't see that as the best option. Brooks Do we have the time available to dally around with optimizing the 767 in all manners before we order them (and run the very real risk of seeing the line shut down in the meantime), or do we take the money we have now and order the first 40 (which is the number the USAF has tossed about as the first firm order volume) with the lesser hose/drogue capability, and then implement the multi-point system on the following aircraft, with the originals being upgraded at a later date? I see the latter as an option that makes as much, if not more, sense than the former. As I've pointed out above, I think an even more fundamental question is should we be buying the 767 at all, rather than some other option. The 767 lease is looking more and more like roadkill, so it may be moot. However, even if we decided to go the 767 route, there's no reason why we couldn't buy 35 of them (or whatever the $ work out to) with wing drogues, rather than 40 without. Guy |

Interesting - could you provide a cite? One wonders if they'll change their tune if the 767 deal falls down. Guy |

Still clinging to the past I see Brooks With the DSB report out the point is pretty much moot. http://www.nytimes.com/2004/05/13/bu...partner=GOOGLE With no civil orders forthcoming, Boeing isn't likely to keep the 76 line open beyond whats been ordered. Already marginalized in the budget process anyway, that does not bode well for the E-10 either. Its time to move from the concepts of the last century anyway. As the report says... A page of the report, for example, calls for the Air Force to "work with major airframe manufacturers to develop new tanker options" that would have "more modern airframes" than the "20-year-old 767 design." Instead of sinking money into old, orphaned airframes, it would be much better to invest in something like the "MACK" or BWB that could be optimized to operate and survive in tomorrow's ari threat environment. Potential adversaries are realizing that we are concentrating a very signifcant part our ability to mount offensive operations into rehashed airliners...even if the august members of this board don't see it. They are doing something about it too... http://www.indiadefence.com/collab.htm Designed to fulfill the BVR (beyond visual range) role for "outer-air battles", an aircraft usually of Sukhoi-27/30/35/37 "Flanker/Super Flanker" family, equipped with KS-172 (also referred to as Article 172) would be able to engage ultra-high-value airborne platforms like AWACS (airborne warning and control system), IFR (in-flight refuelling) and LRMP (long range maritime patrol) platforms, without necessarily having first to deal with their fighter escorts. http://www.ainonline.com/Publication...1agatpg85.html If used on a long-range missile airframe, the ARGS-PD could give an opposing air force the ability to take out strategic targets at distances outside of the normal interception envelopes of U.S. or other NATO fighters. Boeing E-3 AWACS or E-8 JSTARS aircraft–platforms that U.S. forces depend heavily upon in time of conflict–would be vulnerable as never before. http://arms.ashst.com/missiles/s400.htm The S-400 system is intended to engage current and future air threats such as tactical and strategic aircraft, Tomahawk cruise missiles and other type missiles, including precision-guided ones, as well as AWACS aircraft, at ranges of up to 400 km. http://in.news.yahoo.com/031020/43/28nkk.html "The FT-2000 surface-to-air missile (SAM), commonly known as the 'AWACS killer', designed by Chinese experts are considered to be the most appropriate option if the U.S. refuses to provide the same kind of Airborne Warning and Control System (AWACS) to Pakistan being sold to India by Israel," The News said. |

company big bucks). We need to see if it makes more sense to buy 7E7s at the _start_ of their production cycle, rather than 767s at the end of theirs. I forgot to put in the link about what Boeing has said about the unsuitability of the 7E7 in the tanker role...Of course they could be lying thru their teeth in order to keep the 76 alive.... http://www.afa.org/magazine/april2004/0404watch.asp However, a senior Boeing official said the 7E7 would be ill-suited for tanker duty. "The E in 7E7 stands for efficiency," he said. The efficiency comes from the use of "very lightweight materials" to achieve long range. The 7E7 will have too much flex in its wings and fuselage to be a good tanker, the Boeing official said. "For a tanker, you want a really rigid, sturdy platform, like the 767." |
