A Balao class submarine built in 1943, the USS Blenny (SS-324) saw action in World War II throughout the Pacific theater, eventually earning four battle stars, as well as during the Korean War. Sometime during 1969 she was re-designated as an auxiliary submarine (AGSS-324) and in September she was placed in reserve. Two months later, Blenny was finally decommissioned, berthed initially at Philadelphia. Her name was struck from the Navy list on 15 August 1973. Subsequently moved to Portsmouth, Virginia, she remained there until 3 July 1979 at which time she was moved to the naval station at Norfolk for a period of temporary duty. In 1984, it was planned to use the submarine for an exercise target, but that apparently never happened. Instead a decision was made to donate her to Maryland for use as an artificial reef in 1987.

She was eventually scrapped and sunk off Ocean City as part of the Maryland Artificial Reef Program. The 311 foot long sub rests in 70 feet of water in the vicinity of the African Queen. Holes have been cut and hatches opened to make for an interesting penetration dive.
