The British Royal Navy has formally named the fourth Batch 2 River-class offshore patrol vessel (OPV) as HMS Tamar at a ceremony in Glasgow.

The 90m-long HMS Tamar, which was launched in October last year, is the fourth of five OPVs built by BAE Systems under a £635m contract. The remaining vessels are HMS Forth, HMS Medway, HMS Trent and HMS Spey.

Once the Royal Navy receives the new River-class vessel, it will be deployed to perform counter-terrorism and anti-smuggling missions and provide support to defence operations.

The ship is equipped with a 30mm cannon and a flight deck that can accommodate a Merlin helicopter.

“From patrolling our coastlines and protecting UK waters, to anti-smuggling and counter-terrorism operations, these ships are a key part of our Royal Navy fleet.”

UK Defence Procurement Minister Stuart Andrew said: “From patrolling our coastlines and protecting UK waters, to anti-smuggling and counter-terrorism operations, these ships are a key part of our Royal Navy fleet.



“Today’s naming marks an important milestone in HMS Tamar’s programme ahead of starting sea trials and being accepted into operational service next year.”

Under the contract, BAE Systems first builds all the vessels at its Govan shipyard in Scotland.

Prior to embarking on sea trials, the vessels are moved to the company’s Scotstoun site to undergo outfitting.

UK Defence, Equipment and Support chief executive Simon Bollom said: “HMS Tamar continues the legacy of ships being built on the Clyde for the Royal Navy and will perform a vital role defending the UK’s interests.

“We look forward to the delivery of the remaining OPVs and the further progress on the Type 26 build programme.”

The Royal Navy is expected to receive all the Batch 2 OPVs by the end of next year.
