Unit History

The First Severn1695

The first HMS Severn was a Fourth Rate two-decked ship of 50 guns launched in 1695. She had a distinguished record of service before finally being broken up and rebuilt in 1739.

The Second Severn1739

The second HMS Severn was rebuilt from first and was launched in 1739.


Severe damage during a battle with French line-of-battleships in 1746 caused HMS Severn to strike her colours to the superior force. The ship was recaptured a year later at the battle of Finisterre.

The Third Severn1747

The third was again a Fourth Rate 50-gun two-decker launched in 1747. Her career was significantly less eventful than her predecessors and she was sold out of service in 1759.

The Fourth HMS Severn1786

The fourth HMS Severn was a 44 gun Adventure Class fifth rate. Launched in 1786 she was wrecked in 1804.

The Fifth Severn1813

The fifth was an 'Endymion' Class Fourth Rate 40-gun ship. These 'fir-built' softwood ships were not long-lived and the ship, leaky and unseaworthy, was sold for breaking in 1825.

The Sixth Severn1856

The next HMS Severn was one of the last frigates to be built as a sailing warship, eventually broken up in 1876 after only one active commission to the East Indies.

The Seventh Severn1885

The seventh ship represented a great technological leap forward. She was a 'Mersey' Class protected cruiser, the first cruisers to be built with no sailing rig, as solely steam-powered ships.

The Eighth Severn1914

In 1914 the RN purchased three Amazon river monitors built by Vickers for Brazil. These, renamed Mersey, Humber and Severn, were the first of specialist shore-bombardment ships.
