Gibraltar, the dockyard is now operated as a commercial facility by Cammell Laird Gibraltar, although there is still a Royal Navy presence, which provides a maintenance capability. Gibraltar’s naval docks are an important base for NATO. British and US nuclear submarines frequently visit the Z berths at Gibraltar (source: Hansard). A Z berth provides the facility for nuclear submarines to visit for operational or recreational purposes, and for non-nuclear repairs.
The naval Battle of Gibraltar took place on April 25, 1607 during the Eighty Years’ War when a Dutch fleet surprised and engaged a Spanish fleet anchored at the Bay of Gibraltar. During the four-hour action, the entire Spanish fleet was destroyed.
