Pictured is RFA Tidesurge, the third of the Royal Fleet Auxiliary's mew Tide-class tankers to be made. The ship photographed in Cornwall for customisation and trials before entering service with the Royal Fleet Auxiliary and being deployed on operations with the Royal Navy. The arrival of RFA Tidesurge comes just weeks after her sister ship, RFA Tidespring, met up at sea with aircraft carrier HMS Queen Elizabeth for the first time. The 39,000-tonne tankers with a range of 8,000+ nautical miles can carry up to 19,000 cubic metres of fuel and 1,400 cubic metres of fresh water in support of Royal Navy operations all over the world. The detailed customisation work to prepare RFA Tidesurge and her sister ships for operations is being undertaken at the A&P shipyard in Falmouth, sustaining around 300 jobs.
