WThe Archer class is a class of patrol and training vessel in service with the United Kingdom's Royal Navy, commonly referred to as a Fast Training Boat. Most are assigned to University Royal Naval Units, although HMS Tracker and HMS Raider are armed and provide maritime force protection to high value shipping in the Firth of Clyde and are most commonly employed as escorts for submarines transiting to Faslane. Pursuer and Dasher are also armed and provide maritime force protection operating with the Gibraltar Squadron.
