:  TIRU's keel was laid by the Mare Island Naval Shipyard, Vallejo, CA. She was originally scheduled for launching in November 1944, but construction work was suspended at the end of World War II. TIRU's percentage of completion saved her from the scrap pile which claimed the other submarines on Mare Island's building ways.

Cromwell, whose husband, the late Captain Cromwell, USN, was a submarine Attack Group Commander and chose to go down with the USS Sculpin (S-10), off Truk atoll in 1944, rather than be captured by the Japanese (awarded the Medal of Honor).
