USS Burrfish continued her hectic wartime activities with her sixth and final patrol from March 25th to May 4th, 1945. She was a member of a wolfpack in the Luzon Straits. She was forced to dive in a hurry by an aircraft, and later was forced down again and strafed, fortunately without incurring damage.
During this eventful patrol she avoided damage from a floating mine, and, finally, attacked a shore radio station on Bataan with gunfire. Burrfish proceeded to Saipan, then to Pearl Habour, arriving there on May 13th.
Sent home to Portsmouth Navy Yard for a major overhaul, she arrived on June 19th, where she remained until the war ended on September 2nd.
USS Burrfish would never again fire a shot in anger, but she had much more history to make.
