ROYAL NAVAL VESSELS

DUKE CLASS FRIGATES (TYPE 23)

 

HMS Richmond Type 23 Duke Class Destroyer

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. The class is now completed.  

 

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.
