This weapon was used on the North Carolinasand South Dakotas. They were a lightweight version of the Mark 1, firing a heavier shell at a lower velocity (which reduced barrel wear) and with a somewhat higher rate of fire. There were concerns about the flash safety of the ammunition lifts, but this never met the test of combat since no Mark 6 turret or barbette was ever penetrated by hostile fire.
