"Speed is life" was drummed into my brain starting with FAM-1 in the F-8.
Particularly vital in an era where any likely adversary would eat you alive in a slow turning fight. Also useful when it was time to leave the scene .... max speed to disengage and get to feet wet and safety. We're not talking big mach numbers at altitude, but big knots(AKA Q) relatively low .... shrinking missile envelopes and generating separation from the bad guys. Had an interesting conversation with a PXO (former Bug driver) who just finished 4 years at the puzzle palace. He claimed we didn't need speed in tactical aircraft. By default we don't have it in USN aircraft. The F-18C/D can't exceed 700 knots on a good day. The E/F is slower. They're impressive at high alpha (only the F-22 and modded flankers are better), but they're not dragsters (they're also a bit weak in endurance and range). But no matter. Alleged reason: It's cheaper to design a missile that'll kill anyone giving chase than it is to design an airplane that can egress. As the AIM-9X is developed further, it will be able to engage a bogey at or near dead six (!?!). Of course, the argument overlooks the fact that we've been flying F-18's for some 20 years without this capability. In certain Pacific Rim scenarios, an intrepid aviator in a Mig series aircraft could give chase and run down the Bug and put one up where the sun don't shine. Any thoughts? There aren't many potential adversaries that could put up a significant A/A defense and current tactics are to neutralize them early (Six day war style, as opposed to Vietnam), but it only takes one late arrival in the furball to ruin your day. Is the day of the 800+ egress over? R / John |

Speed isn't important? Speed is life! Hell, I flew a turning fool of
an airplane, the F102. Wing loading about 45 psf. All that turn could do was let me go around in tight circles when a faster airplane hawked me. And that only lasted as long as my fuel did. But next I flew the F104A - and 800+ was there if I needed it, even with its original engine. The one with the Dash 19 engine would really step out. AMAF two friends of mine took the birds out to 2.5 - 'only' 300 past the redline. Speed is good! And I bet Ed agrees with me; when you've just PO'ed Charlie by taking out an SA2 site and the other 5 sites are still there looking for you, 745 (all our F4Ds could do with all the junk hanging on them) heading out for feet-wet was very nice indeed. - 745 because our engines were right at the top of the trim band - they sure weren't that fast back home. I don't ever recall complaining about an airplane that wasn't slow enough . . . Walt BJ |

Three armchair thoughts:
1- The need for speed going into a dogfight is increasingly irrelevant. Speed = life was the motto before modern engines. It still applies, but to a lesser degree IMO. The thrust of the F-22 is sick. You can regain energy unlike the Camel, P-51, F-86, F-105, F-4, or even the F-15. You absolutely still need energy, but with better enginges, you have less need for pre-existing speed to provide that energy. 2- "lleged reason: It's cheaper to design a missile that'll kill anyone giving chase than it is to design an airplane that can egress." Ideally, that makes very good sense. Let the missile do the dogfighting. In reality, I don't think missile technology is there yet, so you still need the agile jet, with the ability to disengage. 3- Speed shrinks tail-on missle envelopes. Both S-A, and A-A. I bet the Iraqi's wish they were all flying F-111s when they tried to run on the deck to Iran! Might not have saved them all, but it would have probably saved some of them. Speed increases head-on envelopes. The hit and run tactics of Mig-21s and -25s have proven to be among their better options probably because speed decreases detection time and hence increases surprise. So I think it's clear that speed is, and always will be, an important asset even if engines and missiles continue to improve. It matters for a lot more than just egressing dogfights. TV |

You absolutely still need energy, but with better enginges, you have less need for pre-existing speed to provide that energy. I respectfully disagree (But then, I'm an Engineer/Pilot, not a Fighter Pilot) Speed's still important - It allows you more options when positioning yourself before the merge. The extra velocity does really, Really nice things to your missile kinematice - the faster the launch speed, the more range and maneuverability your missile has. Being whopping fast means that if somebody's trying to intercept you, they've got to pull a lot of G, bleeding of their energy, to try and pull lead. If you can go fast for a long time, like the F-22, you're a whole new type of target. Especially since the -22 is,on radar, a very small airplane. 2- "lleged reason: It's cheaper to design a missile that'll kill anyone giving chase than it is to design an airplane that can egress." Ideally, that makes very good sense. Let the missile do the dogfighting. In reality, I don't think missile technology is there yet, so you still need the agile jet, with the ability to disengage. Well, you can make a missile airframe that accelerates quickly, but sustaining that speed takes a lot of fuel. Which takes up weight and space. There's tradeoff all around, in that area - look at the way the Sidewinder diverged. The original AIM-9B had a motor that put out about 4400# of thrust for a shade over 2 seconds. After that, it's coasting - and it's pretty short ranged. The mk 36 motor used on later Sidewinders puts out about 3,000# of thrust - but pushes along for 4-5 seconds. This gives you a higher speed at burnout, and more distance downrange at burnout - all good things for longer range. The French, with the R.550 "Sidewinder Compatable" went with a higherthrust motor with a roughly 1.5 second burn time - great for a high speed right off the rail, but lousy for range, since the missile starts slowing down an eyeblink after it's launched. After you've figured out what tradeoffsyou want to make, you've then got to stick a guidance system in it. Now you've got to package sensors that can see the target at a long range, and is smart enough to figure out what's the target and what's trying to convince the seeker that it's something else, and then fit it into a 5" - 8" diameter package. (12.7 cm - 20.3 cm) That will get your missile more or less there. Now you've got to set off the warhead far enough away that the fragmet cloud (Think of it as the outer skin of an inflating balloon) hits the target. Fire too soon - too far away - and the fragments are too dispersed to do much damage. Fire too late - too close - and the fragments don't get there at all. Simple enough for a single aspect and set of missile and airplane speeds, but now the fuze has to figure all this out for all combinations of intercept geometry and relative speeds. Proximity Fuze design is hard - when a manufacturer claims that their missiles are so accurate that they don't need a Prox Fuze, (Such as the AIM-4 Falcon, or the Rapier SAM), what they're really saying is "We can't make the blasted fuze work on teh best day we ever had!" So - don't bet on a "Kill everything" missile - consider that an F-22 type target coming at you head on is a very fast, very small (to the missile's sensors - it's only big in visible light) target. Going away, it's still a small target, and the missile's going to have to run long and hard to keep up. 3- Speed shrinks tail-on missle envelopes. Both S-A, and A-A. I bet the Iraqi's wish they were all flying F-111s when they tried to run on the deck to Iran! Might not have saved them all, but it would have probably saved some of them. Speed increases head-on envelopes. The hit and run tactics of Mig-21s and -25s have proven to be among their better options probably because speed decreases detection time and hence increases surprise. Yep. It makes the targeting/interception problem a lot more difficult, both for airplanes and missiles - any sort of aimed fire, really. So I think it's clear that speed is, and always will be, an important asset even if engines and missiles continue to improve. It matters for a lot more than just egressing dogfights. Definitely. Getting to the target and getting back out of the defense in a short a time as possible means that they get less shots off at you. Which is generally considered a good thing. -- Pete Stickney Without data, all you have is an opinion |
