The Fort ships were a class of 198 cargo ships built in Canada during World War II for use by the United Kingdom under the Lend-Lease scheme. They all had names prefixed with "Fort" when built. The ships were in service between 1942 and 1985, with two still listed on shipping registers until 1992. A total of 53 were lost during the war due to accidents or enemy action. One of these, Fort Stikine, was destroyed in 1944 by the detonation of 1,400 tons of explosive on board her. This event, known as the Bombay Explosion, killed over 800 people and sank thirteen ships. Fort ships were ships transferred to the British Government and the Park ships were those employed by the Canadian Government, both had the similar design.
