HMS Archer is the lead ship of the Archer class. As the lead ship she was one of several of her class to be completed in 1985 by Watercraft Marine, the original shipbuilders — most of the remaining vessels were completed or built by Vosper Thornycroft. In 2015, she was one of the first of her class to receive an upgrade.

The 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 Coastal Forces Squadron. 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 were also armed during their deployment on maritime force protection duties with the Gibraltar Squadron from 2020-2022.
