In August 1945, in company with HMS ''Taciturn'', she attacked Japanese shipping and shore targets off northern Bali. ''Thorough'' sank a Japanese coaster and a sailing vessel with gunfire. On 16 December 1957 ''Thorough'' returned to HMS ''Dolphin'', ''Portsmouth Dockyard'', after completing the first circumnavigation by a submarine. While in Australian waters, on 2 August 1956, she rescued one of the four survivors of the sinking of the ' sixty-miler', ''Birchgrove Park''. She survived the war and continued in service with the Navy, finally being scrapped at Dunston on Tyne on 29 June 1962.HMS Thorough
