More like "Steamer Trunk Nukes" or "Footlocker Nukes". Our smallest nuke, the Small Atomic Demolition Munition, wasn't really amenable to being carried about like luggage. Doesn't really matter how tiny (or big) the things are. If they fit in an SUV and can be left on the street and detonated like a regular car bomb, they will suit Al-Qaeda's purpose I think the term "suitcase nuke" just refers to an free floating small sized demolition munition that can be used independent from some type of delivery system such as an aircraft or artillery piece. No, the term "suitcase nuke" became a common (and misunderstood) term when Alexander Lebed came out with his since-discredited claims that the GRU/KGB had built numerous very small devices that could supposedly fit into a briefcase/suitase size satchel and of which some number were supposedly unaccounted for. One congressional committee even saw an extraordinary "mockup" of this fantastic "weapon". None of this has ever panned out as being based in real fact. ISTR some 60's promotional literature from Picatinny Arsenal showing a jeep-mounted recoilless rifle with a crew of two. It was pointed to the horizon and there was a mushroom cloud. I think they talked about yields down to 1Kt. It reminds me of the proverbial nulcear handgrenade. What's the range of a 105 RR ? Of course it was an artist's sketch. The same artists are now working on sketches of nuc bunker busters. Another bad idea IMHO. You are referring to the Davey Crockett, which was indeed fielded. It used the W-54 warhead, the smallest spherical implosion device ever fielded by the US, mounted on what was basically a "spigot" which was inserted into the tube, with the warhead being that bulbous bomb-like contraption sticking out of the end. The same warhead was the basis for the SADM. Brooks -- Al Dykes ----------- |

Brooks Given the old Soviet propensity of duplicating, or attempting to duplicate, so many Western weapons systems, if only on the principle that if we had it they'd better have it too because even if they couldn't immediately see the utility of the system in question, no need to take chances (i.e., they couldn't afford to foster a "suitcase gap") -- how likely is it that they _wouldn't_ have developed such a device? Being as we have seen no cridible evidence that they did (and we have seen photos, accounts, etc., of their nuclear weapons developments since the fall of the Soviet Union), and knowing that they did indeed have some problem providing the materiel for all of the warheads they *did* want, the burden of proof is on those who are claiming they did have these things. So far, Lebed and his followers have been long on talk, short on proof. Brooks David Windhorst |

If that were the case, the freefall bombs like the the B-61, which did not need all of the protection an RV has to have, would have weighed in at less than the 700 pounds or so that they do.

Any of these could be considered a "suitcase" nuke, but not a "briefcase" one. The smallest warhead we ever fielded was the W-54, at around sixty or so pounds and a diameter of around 12 inches.

Actually, it's *exactly* the sort of thing I've walked into hotels with. Much smaller and lighter, actually. Put it in a road case with wheels, and it'll fit quite nicely on an elevator ("it's medical equipment"). I've brought multi-hundred-pound radiation therapy machines into hotel rooms for shows with no comment. Nor would sending the device "air freight" be such a bright idea. Why not? I've drop-shipped thousand-pound boxes of stuff with nobody blinking an eye. Hell, we had them fly a 1200 pound road case full of steel plates from Orlando to Las Vegas. Not all airports have explosive detectors or x-ray machines for airfreight. And if you're really worried about that part, ship it by bus or train. -- cirby at cfl.rr.com Remember: Objects in rearview mirror may be hallucinations. Slam on brakes accordingly. |

If you double the mass of the fissionables, you get a *lot* more than twice the yield, and don't need much more explosives, either. Efficiency for very small weapons is pretty pathetic, actually. the W-79 was a fairly good sized warhed all-up, with a diameter of around 21 inches and a length of a bit over five feet. You mean W-78, right? I was referring to the Mk-12 W-68 warhead, not the -12A. The W-68 "package" was only about 20 inches in diameter and about 40 inches long.

Not so much. The airframe and fuzing mechanisms for any airdropped bomb are, by themselves, moderately heavy. You don't design that sort of thing for lightness, you design it for reliability. You don't want a bird strike to wipe out your multimillion dollar nuke. The B-61 airframes I've seen were *definitely* not lightweight constructions.

It takes a good bit of metal to handle slamming into the water at a good clip. You should note, that unless otherwise mentioned, the specs for the weapons on that page are inside their casings, ready to fire or drop.

Kicked the weight up a *lot*. The W-54 was about 51 pounds all by itself, and could easily fit into a large suitcase or small trunk. But in fact the miniturization has not advanced all that much since the days of the earlier devices like the W-54. You are stuck with a 12 plus inch dimension any way you go aout it for a spherical device; you can go lower with linear implosion, but then your length increases. Which means that, instead of a basketball and a laptop, you have two footballs and a laptop. Not a briefcase, but certainly man-portable.

Take the mechanism out of the steel artillery round, and there you go. About four inches in diameter, and a couple of feet long. Remember that the W-82 weight and size were ready to fire, inside a heavy steel shell. The whole apparatus would have to be no larger than a couple of footballs (or a basketball plus a laptop computer), and less than 50 pounds, for a yield of a kiloton or so. Less than 50 pounds?

I was referring to the Mk-12 W-68 warhead, not the -12A. The W-68 "package" was only about 20 inches in diameter and about 40 inches long. Slightly bigger in volume than a golf club bag. Mea culpa--I wrote 79 instead of 78. But you need to check that data; the W-78 *was* the weapon included in the Mk 12 RV. The W-68 was a much smaller device (40-50 Kt yield) and was used on Poseidon SLBM, not on the Minuteman. The dimensions I gave for the W-78 are apparently correct. And I doubt any 250 pound "physics package" has a yield of 170 Kt. Well, you'd be wrong, according to your own source: http://gawain.membrane.com/hew/Usa/Weapons/Allbombs.html Uhmmm...he indicates the W-78 had a yield in the 300 plus Kt range. Your "much smaller" W-68 had only about a third of the yield you are ascribing to it. The W-69, as mounted on the SRAM, did have a 170 Kt tield, at about 275 pounds, so I will acknowledge that the 250 pound class weapon is apparently indeed capable of much higher yeilds than I thought [possible--but your examples did not do much to get me to that conclusion. :-) If that were the case, the freefall bombs like the the B-61, which did not need all of the protection an RV has to have, would have weighed in at less than the 700 pounds or so that they do. Not so much. The airframe and fuzing mechanisms for any airdropped bomb are, by themselves, moderately heavy. You don't design that sort of thing for lightness, you design it for reliability. You don't want a bird strike to wipe out your multimillion dollar nuke. The B-61 airframes I've seen were *definitely* not lightweight constructions. Likewise, you don't create a "suitcase bomb" that gets turned into at best a fizle yield source when some bellboy bangs it into the luggage cart. SADM weighed in at over 100 pounds--I doubt anyone has done any better in that regard since then. The W-44 ASW warhead was about 170 pounds, and was certainly small enough to fit into a suitcase or trunk (less than 1 foot diameter), with a yield of 10 kilotons or so. No, the W-44 was about 14 inches in diameter, and over 25 inches long. See: http://gawain.membrane.com/hew/Usa/W.../Allbombs.html The W-44, *inside its ASW casing*, was about that big. It takes a good bit of metal to handle slamming into the water at a good clip. You should note, that unless otherwise mentioned, the specs for the weapons on that page are inside their casings, ready to fire or drop. The W-25 warhead for the Genie AAM was about 220 pounds, and gave a yield of about 1.7 kilotons. Any of these could be considered a "suitcase" nuke, but not a "briefcase" one. The smallest warhead we ever fielded was the W-54, at around sixty or so pounds and a diameter of around 12 inches. When configured into your "suitcase" (hate that term) mode as SADM, the weight went up a bit, to a bit over 100 pounds. The SADM had a much tougher casing and was designed to be tamper-resistant. Kicked the weight up a *lot*. Pardon me for saying so, but have you ever been exposed to the SADM in any fashion? Suffice it to say that an exposed physics package is not realistic in this thread--the supposition is that AQ allegedly got its hands on a product of some ex-Soviet device, and it will be a cased device, one that to the best of my knowledge will include a PAL, too (say what you will about the Soviets, but they reportedly took their nuclear weapons control as seriously as we did). SADM added about a hundred pounds to the warhead weight for a reason. The W-54 was about 51 pounds all by itself, and could easily fit into a large suitcase or small trunk. Debatable as to the actual weight; many sources indicate that the actual weight was 59 pounds. The truth of the matter is that we don't *know* the exact weight (they did not even tell us that in the ADM short course). But in fact the miniturization has not advanced all that much since the days of the earlier devices like the W-54. You are stuck with a 12 plus inch dimension any way you go aout it for a spherical device; you can go lower with linear implosion, but then your length increases. Which means that, instead of a basketball and a laptop, you have two footballs and a laptop. Big footballs you have there. Not a briefcase, but certainly man-portable. The dimensions and weight of the 155mm rounds did not dramatically change (W-48 from 1963 at 6.5 inches by 33 inches and 118 pounds versus the W-82 cancelled in 1990, at 34 inches and 95 pounds) over the decades. Take the mechanism out of the steel artillery round, and there you go. About four inches in diameter, and a couple of feet long. Remember that the W-82 weight and size were ready to fire, inside a heavy steel shell. I don't know WHAT that shell was made out of, or how thick it was---for all I know they used a more exotic material, like titanium. Nor do we know the actual cross sectional dimensions of the warhead itself. We do know that a particularly thick outerwall was not *required*, and that the actual physics package diameter could have been as high as maybe six inches, with quarter inch thick shell walls (the need for extreme thickness is not really evident). Your device still needs its batteries, its HE component, its high-speed detonators and associated fuzing, its initial neutron booster--all of the components minus the actual screw in fuze and the external casing. The apparent limit to the package itself, minus the unnecessary accoutrements, is going to be in the 50-60 pound range. If you have found a smaller device, by weight, that has actually been proven to work (i.e., either tested or fielded), please explain what it is. The whole apparatus would have to be no larger than a couple of footballs (or a basketball plus a laptop computer), and less than 50 pounds, for a yield of a kiloton or so. Less than 50 pounds? I doubt that. W-54 remains king of lilliputs as of now, and it was 59 pounds, with a maximum yield of around a quarter of a kiloton. ...and a lot of that weight was 1960s-era electronics, with a mechanical PAL lock. Knock ten pounds off least for a modern design. Not sure about that. Using the W-48 to W-82 as a ratio, we have devices about 80% of the previous weight. How much of that weight savings is in a new, higher-strength, lighter weight casing design? And, you have to remember that the devices in question are supposedly OLD Soviet designs, so your whole they-could-be-much-smaller-because-they-are-newer argument kind of goes right out the window; if anything, the Soviet weapons were MORE bulky and weighed more than our own. AQ does not have a weapons lab at its disposal churning out state-of-the-art nuclear weapons; even the Pakis and Indians have undoubtedly not gotten down to the size capabilities we developed (I don't believe either has developed arty capable packages as of yet). This whole thing sounds like more Lebed-like musings to me. Brooks And, in an operational situation, if the gadget weighed as much as 200 pounds, you'd put it on wheels and roll it around. Look at any transit location and notice the large number of people with wheeled cases. -- cirby at cfl.rr.com Remember: Objects in rearview mirror may be hallucinations. Slam on brakes accordingly. |
