Mersey

HMS Mersey

HMS Mersey is the youngest of the original batch of River class patrol vessels. She patrols the waters of the UK and up to 200 miles in the Atlantic ensuring that fishing boats and trawlers stick to internationally-agreed quotas.

Add to favourites

Mersey was the last ship to be built at Vosper Thornycroft yard, in Woolston, Southampton, for the Fishery Protection Squadron – the oldest unit in the Royal Navy. 

Originally, HMS Mersey like her sister ships, were not owned by the RN, she was leased by BAE who retained the responsibility for any major maintenance and upkeep.  However in 2012 the Ministry of Defence bought the ships outright and they are now owned by the Royal Navy.

The ship is a regular visitor to UK ports and often hosts organised groups to show what the Royal Navy is about. 

She operates a crew rotation system which means that a member of the ship’s company would normally spend four weeks onboard and two weeks ashore catching up on leave or on courses, allowing the ship herself to be on almost constant patrol.

Providing humanitarian assistance

When natural or man-made disasters occur, a country’s infrastructure and resources can be crippled. With loss of electricity, shortage of food and water supplies, and human lives at risk – responding to such life-threatening scenarios is central to the Royal Navy’s ethos. Because we have the skills, equipment and know-how to go anywhere, regardless of potential damage to local infrastructure.

Protecting our economy

Maritime trade is the lifeblood of the UK economy and industry. 95% of Britain’s economic activity depends on the oceans. And every year Britain imports goods worth £524 billion.

The UK is so dependent on the seas for its prosperity, that without the Royal Navy acting as a deterrent the effect on the economy would be overwhelming.
