BLACKWOOD Class (Type 14)

anti-submarine frigate

The high cost of the Type 12 WHITBY design, the premiere RN frigate of the 1950s, prompted the RN to order this smaller, cheaper, and less capable class of anti-submarine frigates. Mounting the same ASW equipment and weaponry of the Type 12 design, these ships were highly specialized in ASW but little good for anything else other than common patrol duties. They also carried a watered-down version of the Type 12 powerplant, with only one shaft and turbine pair. Hull problems surfaced in the late 1950s when subjected to heavy seas, and their hulls were strengthened as a result. Although these ships proved to be the excellent anti-submarine platforms that they had been designed to be, and they gave good service in Fisheries Protection duties, all were scrapped during the 1970s. In the late 1960's, EXMOUTH was used as a test platform for the gas turbine powerplant that would appear in the 1970's and 1980's produced RN ships.
