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.

She is currently deployed as part of Standing NATO Maritime Group 2, the NATO-led operation in the Aegean Sea.

As part of a multi-national task group, and working in close co-operation with Greek and Turkish authorities, she has been on patrol and conducting exercises with other NATO Warships as well as flying the flag for the Royal Navy and the UK in an area rarely visited by British warships.

Providing security at sea

The UK has a responsibility to its citizens and its allies to endeavour to safeguard the high seas. This is why the Royal Navy protects home and international waters – making sure the global trade that Britain and the world depend on can proceed without a hitch.

International partnerships

As the fifth largest economy in the world, the UK has responsibilities towards its allies and partners. But Britain also has global ambitions – namely to protect the seaways underpinning the country’s prosperity. The Royal Navy plays a crucial role in fostering these enduring and lasting alliances with other nations.
