From Wikipedia, the free encyclopedia

HMS Tiara (P351) was a Royal Navy Group Three T-class submarine laid down at Portsmouth Dockyard on April 8, 1943 and launched on April 18, 1944. However the war ended before she was completed and she arrived at Dover Industries for scrapping in June 1947. Her sister vessel Thor was launched on the same day at Portsmouth dockyard and not completed either.
