Cod's 7-Ton Gun

During World War II, Cod carried several types of main deck guns. A 4-inch diameter gun was first mounted forward of the conning tower, and later a 7-ton gun firing 5-inch diameter shells replaced it on Cod and most other U.S. submarines. Unlike previous submarine guns, this wet-mount gun did not have to be sealed and unsealed before and after diving. Its fixed, one-piece ammunition weighed 74 pounds, including a 35-pound shell, and eight men manned the gun.
