RFA WAVE KNIGHT (A389) is seen arriving on the Mersey bound for  Cammell Laird where she is due to undergo maintenance until June. The final photograph, bottom right, shows her in #5 dry dock. Fleet-mate RFA DILIGENCE can be seen in #6 dry dock undergoing an extensive refit which is expected to last for much of the year.

 RFA WAVE KNIGHT was built by BAE Systems, being launched in 2000. She was accepted into service in 2003.

RFA WAVE KNIGHT and RFA WAVE RULER are large fleet tankers designed to replace the Olna and Olwen, two 36,000t displacement fast fleet tankers, built at Swan Hunter and Hawthorn Leslie in the 1960s.

The ships are crewed by 72 Royal Fleet Auxiliary personnel and there is also provision for 26 Royal Navy personnel for helicopter and weapons systems operations.

WAVE KNIGHT is able to operate in support of amphibious forces, anti-surface and anti-submarine warfare operations and protection of vital sea areas and shipping.
