The Bay class was a class of 26 anti-aircraft (A/A) frigates built for the Royal Navy under the 1943 War Emergency Programme during World War II (one of which was cancelled and six completed as despatch vessels or survey ships). They were based on the hulls of incomplete Loch class anti-submarine (A/S) frigates.
In 1959 and 1961, four frigates of the class (Bigbury Bay, Burghead Bay, Morecambe Bay and Mounts Bay) were transferred to the Portuguese Navy. Between 1966 and 1968, based in Mozambique, these ships were part of the Portuguese naval deterrent force against the Royal Navy Beira Patrol which was trying to enforce sanctions against Rhodesia. In 1966 the Portuguese Navy also bought the survey vessel Dalrymple which served until 1983.
