Rosyth Dockyard is a large naval dockyard on the Firth of Forth at Rosyth, Fife, Scotland, owned by Babcock Marine, which formerly undertook refitting of Royal Navy surface vessels and submarines. Before its privatisation in the 1990s it was formally the Royal Naval Dockyard Rosyth. Its primary role is now as integration site for the Royal Navy's newest aircraft carriers - the Queen Elizabeth-class.
