Bay-class minesweeper

The Bay-class minesweepers were a class of minesweepers operated by the Royal Canadian Navy (RCN) and Canadian Forces (CF) during the Cold War.

The class derives its name from bays in Canada and was designed by the RCN as a replacement for World War II-era minesweepers. Fourteen were laid down in 1951–1952, however six were subsequently transferred to the French Navy in 1954. These ships were replaced by six of the same name in 1956–1957 but were assigned new pennant numbers.

They were reclassed in CF service as patrol escorts in 1972 and six vessels remained in service until the late 1990s, providing coastal surveillance and shiphandling experience for junior officers with Maritime Forces Pacific. The removal of the aft mounted minesweeping equipment in the 1970s allowed for the erection of additional sleeping spaces and a wash space for aspiring officers, unofficially known on all ships as "Dunk's Diner".
