Prior to 2003 Pursuer was the training vessel of Sussex University Royal Naval Unit (SUSURNU).

Pursuer and HMS Dasher were sent to Cyprus ahead of Operation Telic, the US-led invasion of Iraq in 2003, transported on board the CEC Mayflower.

Both were fitted with Kevlar armour and three FN MAG general purpose machine guns, with an extra crew member (compared to the P2000s assigned to URNU duties) employed as a Gunners Yeoman.

In September 2012 her force protection duties were taken over by the more modern HMS Tracker and she was reassigned to Glasgow URNU.

[5][6] In July 2020, Pursuer escorted the Spanish patrol boat Serviola out of Gibraltar's territorial waters.
