USS Sea Cat (SS/AGSS-399), a Balao-class submarine, was a ship of the United States Navy named for a shortened form of sea catfish, a marine fish of little food value found off the southeastern coast of the United States commissioned on 16 May 1944, with Commander Rob Roy McGregor in command. During World War II Sea Cat operated within the Pacific theatre, conducting four war patrols in wolf packs accounting for up to 17400 tons in the form of three cargo ships and an enemy vessel. Sea Cat earned three battle stars for her World War II service.

The Balao class was a design of United States Navy submarine used during World War II, and with 120 boats completed, the largest class of submarines in the United States Navy. An improvement on the earlier Gato class, the boats had slight internal differences. The most significant improvement was the use of thicker, higher yield strength steel in the pressure hull skins and frames, which increased their test depth to 400 feet (120 m). Tang actually achieved a depth of 612 ft (187 m) during a test dive,
and exceeded that test depth when taking on water in the forward torpedo room while evading a destroyer.
