Sometimes you find just what you wanted just a little bit late. This happened with the most recent issue of Aerospace Projects Review; it had a big article on the Project Pluto nuclear ramjet cruise missile, with some discussion of early designs including a few lines on a reported North American study from 1947 describing nuclear rockets and ramjets. When the article was published, the North American study was unavailable, and was thought to be likely to be a vague mathematical treatise. However, not long after publishing I came across and photocopied/scanned a copy of that very report. Far from being vague, it was fairly massive and contains detailed engineering schematics of a Mach 3 nuclear ramjet cruise missile, its liquid rocket booster, and what is essentially an enlarged V-2 with a nuclear rocket, capable not only of serving as an ICBM, but also capable of sending a payload onto an interplanetary trajectory.

The next issue of APR will have an update article describing these.

Visited the Rock Island Arsenal Museum today. Used to live near there (parents still do), but I haven’t been to this museum in nigh on a quarter century (egad, I’m old).

The museum has a display case that runs floor-to-ceiling along two walls, and is filled with firearms from flintlocks to, seemingly, the 1970’s or so (not a whole lot in evidence of truly modern firearms). Included are the standards – M-16s, M-1 Garands, AK-47s and so on – as well as some rare and sometimes bizarre one-offs, including several versions of the “SPIW,” numerous versions of the M-79 grenade launcher (including versions with magazines or clips with multiple rounds), and a range of one-offs and experimentals.

Given sufficient ammunition, the Rock Island Arsenal Museum would be the perfect place to make a stand against the forthcoming zombie apocolypse.  However, in case the neighbors Just Won’t Shut The Hell Up, Rock Island Arsenal has another interesting toy: the T131 280mm “atomic cannon.” When you absolutely, positively have to blow the crap out of someone at considerable distance, few things are a more entertaining way to do it than this gun.

NOTE: If you are interested in the X-14 and want to know more about it, check out issue Volume 2 Number 2 of Aerospace Projects Review. Many more of these photos are published there!
While travelling across western Indiana on I-74, I saw a few signs for the “Ropkey Armor Museum.” I figured it might be a nice little diversion, so I took the exit. As I kept driving along the farm roads, I started to lose heart… it began to seem more and more like it’d be a dinky little farm with a delapidated tank or two. When I finally got to the museum, it was in fact a privately owned farm. There were a few pieces of artillery scattered around a sizable prefab steel building. You have to drive past the house to get to the museum proper. Once inside the museum, though, all thoughts of this being a “farm with a delapidated tank or two” faded. I was flabbergasted… the collection is several dozen armored vehicles from all eras in a remarkable state of preservation.

While the collection of armored vehicle was quite impressive, there was one item on display in the back that had my jaw on the floor: the Bell X-14B VTOL research vehicle. A grand total of one X-14 was built, and it ended it’s career with a hard landing. I figured that it was either at some NASA facility, or turned into cat food cans. As it turns out, the second option was close to the truth… around ten years ago a museum staffer saw the X-14 on a list of government items to be sold as scrap metal, and they bought it sight unseen.

The Bell X-14 has clearly seen better days; but not only has it been saved from shredding and melting down into beer cans, it has been moved out of the weather. I was told that there has been interest expressed in transferring it to another museum, where it would be fully restored. All in all, I have to say a big “Thank You” to the Ropkey Armor Museum for saving an important piece of aerospace history.

In you find yourself in the area, drop in. It’s an impressive collection, and well worth the trip.

Plus, they have the one thing that every museum of real quality has to have…

The smallest nuclear weapon the US ever deployed was the “Davy Crockett,” using the w54 warhead (yield about 20 *tons*) launched by a recoilless gun. Range was only a mile and a bit, but with the low yield blast effects would be negligible. But you sure as hell wouldn’t want to be downwind of it.

The US Army Ordnance Museum in Aberdeen, Maryland, has one on display. Not having my Geiger counter on me at the time, I can only assume it’s either a mockup or a disarmed unit.

Photos of a diagram from 1967, showing a proposed variant of the C-119, a “gunboat.” While heavily armed C-119 gunships were built and flew missions in Viet Nam, this gunboat differed in being rather more heavily armed than normal. Three 20mm M61A1 Gatling guns and three 7.62mm MXU-470/A Gatling guns projected from the port side, and one of each projected from the starboard. The reason for that is murky, to say the least… beacuse if the plane was banked so that the port guns could lay fire on a ground target, the starboard guns would be pointed up into the sky.

The plane was also heavily armored and equipped with flares.

Counter Rocket, Artillery, and Mortar

This is a US Navy 20mm Phalanx anti-missile gun system mounted on a trailer, and used to bring down rockets and mortar shells in Iraq. It uses special ammo that blows itself up in flight so that the shells don’t come raining down  on civilian areas.

Videos of the system in use are available here, here and here. Note that the rounds in flight all sparkle out at the end and disappear… that’s the self-destruct.

One thing that occurs… the trailer system looks pretty large. Yet decades ago the same gun was mounted to APCs; I’m left to wonder why the current system requires such an extensive infrastructure. Shrug.

Was previously unaware of the existence of this place, but it’s a spiffy privately-owned museum of military vehicles. Mostly trucks and the like, but a fair number of tanks, helicopters, a DUKW (being refurbed) and armament. Located just off the highway in Lexington, Nebraska, it’s easy to get to and worth visiting.

Mostly packed, though I’m still at a bit of a loss as to how exactly I’ll deal with the cats. The sun is about to go down; some car packing, and then I’ll go out and look at the Milky Way for a while. Assuming I don’t get canned right off the bat (you never know), I suspect it’ll be a good long while before I see the night sky again. That close to primary targets like Baltimore and D.C., the night sky is more of a “theory” than a “fact.”

Sigh.

Oh, well, maybe one of these days a platinum meteorite the size of a grapefruit will hit my house and I’ll be able to afford an old missile complex somewhere out in the middle of nowhere. Admit it… you’d want one of these too.

Circa 1960, these graphics show a number of payloads that Boeing was projecting for the future. Notice how many of them are Dyna Soar related or derived, including ICGMs (Inter Continental Glide Missiles), orbital bombs, orbital recon systems and most impressively, lunar landers (this was before the idea of Lunar Orbit Rendezvous took hold). Also of note are some non-Dyna Soar payloads, such as satelite inteceptors, recon systems and a 5,000 ton Orion vehicle.

Unlike many, Raedthinn does not have a pathological fear of firearms. Consequently, I’d trust his opinions on gun rights over those of, say, Nancy Pelosi.

Cobray M11. A fine piece; a mite clumsy and certainly kinda big and heavy for a pistol that fires the puny 9mm round, but it was originally designed for full auto, and larger size and greater weight give controlability advantages at high rates of fire. On the other hand, it’s inexpensive and about as mechanically complex as a hammer… it is by far the easiest pistol I own to disassemble and clean. It is, of course, Greatly Feared by many. It is semi-automatic, not full auto; and the round it fires is relatively weak and entirely common. But it looks funny, thus legislatures in several states have outlawed this particular weapon. And thus criminals, who by nature obey the law, make sure to not use it…
