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

[1][2] Along with the batch 2 Archer class, HMS Raider, Tracker is part of the Faslane Patrol Boat Squadron based at HMNB Clyde.

As a "batch 2" vessel, Tracker has a sustainable top speed of 24 knots, faster than her batch 1 sister ships due to her more powerful turbocharged MTU diesels; she can exceed 24 knots in suitable sea conditions.

Both Raider and Tracker operate in the force protection role, providing maritime security for high value shipping in the Firth of Clyde, and are armed with three general purpose machine guns.

She served with Oxford University Royal Naval Unit for sea-based training of both students and regular personnel in UK and European waters.
