The Tribal class frigates of the Royal Navy emerged in the early 1960s as a result of design work started towards the end of the Second World War into future surface escort vessels. New technologies were introduced including gas turbine propulsion and anti-submarine helicopters. Seven frigates of this class, not universally liked, were built and served over three decades East of Suez, in the Caribbean, and in Arctic waters during the Cod War with Iceland. The author describes the class from their ordering to their eventual de-commissioning, conducting interviews with former crew members. The seven were : ASHANTI, ESKIMO, GURKHA, MOHAWK, NUBIAN, TARTAR and ZULU.
