The 750th ship to be launched at the Govan shipyard, now run by BAE Systems, when she entered the Clyde on 9 April 2004, the Royal Fleet Auxiliary MOUNTS BAY was the first of four identical sisterships to be handed over to the RFA, joining it in December 2005. Designated as Landing Ship Dock (Auxiliary), MOUNTS BAY and her sisters were built as replacements for the aging 'Sir Bedivere' class LSLs which dated from the 1960s. Based on a Dutch design, she has a floodable stern dock for landing craft, and a large flight deck which can accommodate two helicopters. She is 176 metres long, and has a displacement of 16,160 tonnes. She has a complement of around 60 and can carry over 300 troops. Her maximum speed is in the region of 18 knots, and she is fitted with diesel-electric propulsion. MOUNTS BAY was heading upriver to Glasgow, where she berthed in King George V Dock.
