LOCH-Class Frigate ordered with seven other of this Class from Swan Hunter at Wallsend on 13th February 1943. Only five of the were completed and two were converted for use as Depot Ships during build. The three others completed as Anti-submarine Frigates were all sold to Commonwealth navies after the end of WW2 and served for many years after hostilities ended. This ship was laid down on 15th July 1943 and launched on 20th January 1944 as the first RN ship to bear this name. Build was completed on 2nd August 1944 and the ship was transferred to the Royal Canadian Navy which provided the crew under an Inter government Agreement in exchange for ALGERINE Class minesweepers built in Canada also manned by the RCN. This arrangement allowed prefabricated construction in British shipyards whilst some of these minesweepers could be built in Canada. After the end of WW2 this frigate was transferred to the Royal New Zealand Navy and renamed HMNZS TUTIRA.
