The first of class was ordered from Yarrows on 29 October 1984 at the
height of the Cold War. Further batches of three were ordered in
September 1986, July 1988, December 1989, January 1992 and February
1996. There
were some early problems, e.g. the Command System was not operational
as quickly as had been planned, but these have been overcome and the
RN has made steady improvements to weapons and sensors in the ships
over the years since first introduction.
From
1999, the Lynx helicopter was replaced on some of the vessels by the
EH 101 Merlin helicopter. These ships are powered by a CODLAG system
(Combined diesel-electric and gas-turbine propulsion) and the
diesel-electric is used for minimum underwater noise during ASW
operations.
