HMS Tamar is the fourth of five River-class Batch 2 OPV on order for the Royal Navy. She was launched in October 2018.

Over the past few weeks the ship has been operating around Plymouth Sound and the South West sea training areas, carrying out her acceptance trials and a series of firsts for the ship and her crew. These has included the first helicopter landing – a Wildcat from Royal Naval Air Station Yeovilton, her first gunnery exercises, as well as boat drills and emergency exercises, that has put the crew through their paces.

HMS Tamar also has the distinction for being the ‘Greenest Ship in the Royal Navy’ – fitted with ‘catalytic converters’ which reduce nitrogen-based emissions from her engine exhausts by up to 95 per cent. She weighs in at 2,000 tonnes, has a 6,000 mile range and a flight deck capable of carrying a Merlin helicopter. She also has accommodation for up to 50 Royal Marines Commandos and is considered by her crew as the ‘Swiss Army Knife’ of Royal Navy vessels.
