HMS Severn

HMS Severn (P282)

HMS Severn is a River-class offshore patrol vessel built by Vosper Thornycroft at their Woolston yard in 2002. With her sisters Tyne and Mersey, she is one of three offshore patrol vessels ploughing the seas around the UK almost every day of the year.

The second of the original batch of River Class ships, ‘Lucky Severn’ - a nickname she owes to the namesake submarine which came through all of World War 2 - HMS Severn patrolled home and overseas waters (including an eight-month stint in the Caribbean in 2015) for 14 years until 2017 when she paid off.


She became the first Royal Navy vessel in nearly 40 years to be recommissioned, brought back to life and recommissioned in 2020.
