The Wackiest Ship in the Army (1960)

"You'll crack your timbers when you see how the Navy sticks the Army sad sacks with the crumbiest ship afloat!"

Lieutenant Rip Crandall is hoodwinked into taking command of the "Wackiest Ship in the Navy" – a real garbage scow with a crew of misfits who don't know a jib from a jigger. What none of them knows, including Crandall, is that this ship has a very important top-secret mission to complete in waters patrolled by the Japanese fleet. Their mission will save hundreds of allied lives – if only they can get there in one piece.
