Re: Unidentified deep well flatcar

Actually the container was designed to retain the nuclear material if the regular explosive went off but the bomb did not detonate. My father was a military officer assigned to the project, so I have read a lot of about the effort.

Actually, Dan, there WAS a vessel designed and built to contain a nuclear bomb... strange as it may seem. Frankly, when I first read about it, I didn’t think it would work, and apparently it was never tested. It was written up a few years ago, when a lot of information from the Manhattan Project was declassified. It was designed to withstand the pressure of the explosion, however I believe that the extreme temperature of even the small yield A-Bomb of the day combined with the pressure would have overwhelmed the “containment” vessel. This photo may well have been of it. Additionally It does not look like any of the reactor vessels I am familiar with... there are no inlet and outlets for the primary coolant.

Whatever it is, it’s NOT “the gadget”, the first A-bomb. It’s too large, and altogether the wrong shape. It looks like a pressure vessel, possibly a reactor containment vessel. "The Gadget” was assembled at Los Alamos, and detonated nearby. There are photos of it being hauled around by truck. The shell of it may have been shipped in by rail, but THIS is not that. There’s not much point in putting a pressure vessel around an A-bomb. Does it say WHERE the photo was taken. Hanford, WA, maybe?

As for nuclear bombs, they have to be moved "somehow”. Nobody but the government knows for sure. For years it’s been assumed the infamous “DOD white train” is used for this … nowadays mostly hauling ICBMs and warheads about. There are a lot fewer of them today than at the peak of the cold war. The missiles are also much smaller.

Hi folks,

Does anyone have any idea of what railroad owned the deep well flatcar in the photo attached
that the first A-bomb was being unloaded from in the desert? This is from recently released CIA
documents. Then, too, it could have been government owned. Presume such things are still
shipped in a similar manner. Just as long as they are not armed!

Cordially, Don Valentine
