In mid 1942 the Japanese AI twice sent a flotilla of the little Daihatsu troop barges - and only the troop barges - apparently to try assaulting Noumea. They were spotted early by PBYs and I had already had a large task force set up in the southwest Pacific, so it didn't go well for them.
I've seen the AI do that in my game, though they were a bit more ambitious in their target: they tried to land on Oahu and got smashed by a small force made up of 2 old USN BBs, HMS Warspite, and a couple of destroyers. So many "LB obliterated by near miss" messages....
