Sunfish (SS-281) One of the severest drubbings ever given a submarine was handed out to the USS Sunfish by Japanese surface craft in the Sea of Okhotsk in the summer of 1944. By the time the enemy ceased the attack, the USS Sunfish had survived 186 depth charges, 86 of them close. The drain on physical reserves that goes along with sustained enemy action is described in this episode of the Silent service.
