[QUOTE=jon_norstog;48363]Louis,

The B-25 optionally carried a 75mm gun in the nose. At least one Japanes destroyer was sunk by B-25s using cannon.It may have been the Ariake in July '43.

Funny story bout that When they first used that 75mm, each time they fired it they were recieving heavy flak.

Turned out it wasn't from their target. The airforce types knew NOTHING about fuze setting, so they thought you screwed it all the way round to make it work. This resulted in ZERO time delay and the round was going off as soon as it left the muzzle!
