The Overseas Patrol Squadron is a front-line squadron of the Royal Navy with responsibility for patrolling the UK's Extended Fisheries Zone, both at home and around British Overseas Territories. The squadron, with headquarters at HMNB Portsmouth, is equipped with eight of the River-class patrol vessels.

HMS Tyne is a River-class offshore patrol vessel built by Vosper Thornycroft in Southampton for the Royal Navy to serve as a fishery protection unit within the United Kingdom's waters along with her two sister ships Mersey and Severn. All three were commissioned into service in 2003 to replace the five older Island-class patrol vessels.
