HMS Lancaster is undergoing a £17.9m refit at Portsmouth Naval Base.
BAE Systems will install a small calibre 30mm gun which can be remotely operated and upgrade the ship’s Seawolf guided missile and the command and communications systems.
Work will also be done on the ship’s hull as well as its power and propulsion machinery, which will reduce her fuel consumption.
BAE Systems’ Barry Woolley, who is leading the refit, said: ‘The work that we are now undertaking in partnership with the Royal Navy here in Portsmouth will boost the war fighting capability of HMS Lancaster to ensure that she returns to the fleet in 12 months, fighting fit and continues to deliver exceptional capability to the navy for years to come.’
The refit is expected to be completed in March next year.
