HMS Dasher is an Archer-class P2000 patrol and training vessel of the British Royal Navy.

[1][2] Prior to 2004, Dasher was based at Devonport as the training vessel for University Royal Naval Unit Bristol (URNUB).

Dasher and HMS Pursuer 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, she swapped places with the more modern HMS Raider and returned to Devonport as the training vessel of Bristol URNU.
