I'd imagine there were some MANPADs, however the only visable damage from the low level sorties were holes from AAA. GRAIL, the first effective Soviet ManPADS, did not reach the field until about '73 as U.S. forces were clearing out of Viet Nam. SA-7s were used in 1972 during the Easter offensive, and drove the slow FACs, Spads and gunships to altitudes that made them much less effective. I guess you were too fast and too low for 88's or similiar artillery. Once again, it depends. Usually those higher calibre AAA pieces can only be fired from a minimum elevation and if your low enough it simply becomes a problem of being able to lower the muzzle enough. ADA of heavy calibre such as the FlAK 88 was passé by the time the NVA was pinging away at the B-52. The radar/fuze/gun combinations like Skysweeper, the Soviet 100mm and the German 88 just hadn't kept up with a gunnery problem that was jet- rather than prop-driven. Whil AAA guns firing on a BUFF at high altitude had an extremely low pK, they (almost certainly 100 or 130mm; the 85mm would be way out of its envelope at the heights the Buffs were flying, above 30,000 feet) still managed to cause damage to at least one BUFF during LB II. Missiles could provide the required single-engagement probability of a kill. The comparative precision of B-52 strikes and the selectivity of their direction meant that area missile systems like GUIDELINE and GOA were required -- the bombers were just too likely to be flying in airspace that guns could not cover or were not covering. CAS and BAI were different. The point nature of the defended assets meant that they could be defended effectively with proximity-fuzed guns such as S-60 and ZSU 57-2, and contact-fuzed or API-T-firing guns like the ZSU, ZPU and ZU guns. Despite numerous accounts by Vietnam aircrew who thought they were being targetted by prox. fused shells (or time shells on the 57mm), there wasn't any prox. fused ammo for the Soviet guns then, and unless some other country is making them for that ammo there still isn't. I suspect it was well beyond Soviet electronics production capacity to turn out the number of fuses (hundreds of thousands if not millions) required of the necessary quality, just to throw it away after a single use. A big SAM is a different matter, essentially a silver bullet, and a prox. fuse is well worth the cost and is subject to a much more benign environment as well. Besides, at the time it may well have been beyond their capability to make one that small; at the end of WW2 the smallest prox. fuse round was for the US 3"/50. In the '50s or maybe early '60s I think Bofors had made one for _their_ 57mm. By the early 1970s or so Bofors had managed to make one for the 40mm/L70, that was small enough that it provided a useful increase in lethality (along with improvements to the shell itself - the rounds were pre-fragmented, improving the fragment pattern density and size). Aside from reliability, the lethality issue is key -- 57mm guns like the S-60 and the ZSU-57-2 used contact fused shells with a self-destruct fuse, because it made no sense to use time fuses on them. Using a time fuse would have slowed down the rate of fire (owing to the time required to set the fuse) and decreased the explosive load (because the fuse would take up more space, in the shell, displacing explosive) resulting in a _decrease _ rather than increase in lethality. Indeed most manpads like the SA-7 only have point detonating and graze fuses, because their warheads are so small that prox. fuses aren't considered worth the extra cost and complexity. As the predicted pH of the missile rises, it's tempting to forego prox. fuses; after all, if you can theoretically guarantee a direct hit, why use a prox. fuse with a bigger warhead when you can use a smaller warhead inside (or in direct contact with) the target, and put the weight saved to use improving the missile performance or the guidance, or else make the whole thing smaller and lighter? This is the idea behind the design of "hittiles" such as Rapier. Unfortunately, Rapier like most missiles of its generation, proved to be much more of a "_miss_ile" than a "_hit_tile", but missile capabilities have improved considerably since then. To a certain extent the same holds true with prox. fuses. Until electronic miniaturization can make the fuse small enough, it makes no sense to use a prox. fuse that will displace explosive/fragments, especially if the lethal volume of the shell is small in size in the first place. That's why small caliber weapons (small referenced to a particular era) don't use prox. fuses; it just isn't worth it. I think they may have Prox. fuses for the 35mm Oerlikon now but don't remember for sure, and FAIK 30mm rounds like Goalkeeper could use them as well. But AFAIK it's still not cost-effective to do so, at least given the intended target set. Guy |

From what I recall of a Discovery Channel docco (which is a complete authority level higher than Disney) Harm was intended as an airburst weapon. Not intended to explode on contact with the transmitter, but 30-50m above it, ensuring that the blast and fragments from a near miss would fill the antennae full of holes and disrupt the comms equipment underneath. The fragmentation pattern, as well as the fragments themselves would be a fairly reliable signature - compared to the expanded rods that you would expect to see on an air-to-air or ground-to-air weapon. Thanks Bufdrvr and Dave, The Warhead is a framentation type with cubes of tungsten to penetrate lightly armoured vehicles. The proximity fuse is an active laser. |

The missile managed to home in on the tail-mounted gun-laying radar of the B-52G, and obliterated a sizable chunk of the rear fuselage when it hit. Fortunately, the damaged B-52G was able to land safely at Jeddah. I've talked to guys who were on that jet and they all tell the same, humerous, story. At first impact they were all thrown back in their seats...then the drag chute deployed due to the gaping hole that allowed it to escape...the drag chute, despite being over 200 knots above its max deployment speed caused everyone to be thrown forward in their seats...then it shreded which, once again, threw everyone back in their seats. The entire sequence took less than 5 seconds. BUFDRVR "Stay on the bomb run boys, I'm gonna get those bomb doors open if it harelips everyone on Bear Creek" I spoke to the EWO of that BUFF at the Whidbey air show in 92 or 93 and showed him around the back seat of the Prowler (crappy view but much better than his!) He was pretty darn sure that the HARM that hit them came from their own F-4G SEAD protection. I obviously won't go into the parametric data of the intended shot target and it's likeness to the BUFF tail radar but having looked at both the target radar and the BUFFs I can easily see it happening if you didn't have an o-scope or raw audio to differentiate. He backed that up with after action reports from that night and it looks like that Weasel was the only place it could have come from. Pugs |

My Janes missile book (1975) makes no mention of GRAIL's employment before the YK War. The Oerlikon AHEAD (Advanced Hit Efficiency and Destruction) ammunition is time-fuzed ("ETSQ" as opposed to "MTSQ") and set electronically _after firing_ through transmitters at the muzzle integrated into the muzzle velocity measuring base. It's a neat trick but one unfortunate effect is that it shortens the guns' range by about a kilometre. What it does provide is the capability to shred UAVs, cruise missiles, and some ARMs and LGBs. I haven't been in recent contact with the regiment that uses these, but I would like to find out if a mix of ammunition would work (one barrel HEI-T, other barrel AHEAD). http://www.rheinmetall-detec.de/img/...S0307-66_1.jpg -- Andrew Chaplin SIT MIHI GLADIUS SICUT SANCTO MARTINO (If you're going to e-mail me, you'll have to get "yourfinger." out.) |

They got repeated SAM calls from the RJ, and never retrograded. The opinion at the time, was they were really scoring big kills and got target fixation, and then were blown out of the sky. |

Subject: B-52 attrition rates?
From: funkraum spam Date: 8/11/2004 5:45 AM Pacific Standard Time Message-id: (ArtKramr) wrote: Pugs [...] Which war? Vietnam, Desert Storm, Balkans, Serbia, Afghanistan or Iraq? It's been in all of them but only suffered losses due to enemy action in Vietnam. Pugs Viet Nam please. Isn't it amazing that there were no other losses in all those other wars? I remember some comments by an East German intelligence operative visiting Cuba in the 70s, who was shown the battleground of the Bay of Pigs: He mentioned how he was shown some 'B-52 wreckage' as part of the tour. I had never heard of B-52s being used in the Bay of Pigs, nor any combat losses over Cuba. My guesses we a) A theatre set building company in Havana had run-up some "B-52 wreckage" . Che & The Beard's advance across Cuba contained high levels of amateur theatrics (machine guns being fired in the background during hammed-up radio broadcasts etc), so this would fit. b) The NVA had gone into the "B-52 wreckage" export business c) All former scenes of battle with the Imperialist Pig-Dogs contain "B-52 wreckage" by definition, visitors being required to nod appreciatively. I think an A-26 Invader was lost. But am not sure. Arthur Kramer 344th BG 494th BS England, France, Belgium, Holland, Germany Visit my WW II B-26 website at: http://www.coastcomp.com/artkramer |
