https://en.wikipedia.org/wiki/USS_Intrepid_(CV-11)From April–October 1971, Intrepid took part in NATO exercises, and made calls in the North Atlantic and Mediterranean ports of Lisbon, Plymouth, Kiel, Naples, Cannes, Barcelona, Hamburg, Copenhagen, Greenock, Rosyth, Portsmouth, and Bergen. During this cruise, submarine detection operations were conducted in the Baltic and at the edge of the Barents Sea above the Arctic Circle, under close scrutiny of Soviet air and naval forces. She subsequently returned to her homeport to be refitted.
Beginning in July 1972, Intrepid participated once again in NATO exercises, visiting Copenhagen, Rotterdam, Bergen, Brussels, Portsmouth and Gourock. Intrepid found herself in the Barents and made round the clock flight operations as she was above the Arctic Circle. She cut her North Atlantic cruise short, returned to Quonset Point for a mini-overhaul. She made her final cruise in the Mediterranean, stopping twice in Barcelona and Malaga Spain; Lisbon, Portugal; Nice, France; Naples, Italy; Palma, Majorca; and Piraeus, Greece once. Due to fuel limitations Intrepid spent as much time in port as she did underway.
