re: #59 pre-Boomer Marine brat

From
what little this layman has read, a gun-method device is pretty danged

They’d have to test a plutonium implosion weapon, to make certain they’d gotten it right, but not the other.

Actually, we successfully tested a shotgun fission device that fit into an 8” artillery shell. (and was fired from the piece)
