 The US Navy moved its anti-submarine air-patrol operations from the old NAS Bermuda flying boat base, to the USAF Base at Kindley Field when its Martin P5M Marlin flying boats were removed from service in the 1960s.They were replaced by Lockheed P-2 Neptune landplanes, which could not operate from the existing Naval Air Station, which had no hard surface runway ashore.The US Navy took over the airfield entirely from the USAF in 1970 and the base continued to operate anti-submarine patrols, first with Neptunes, then with Lockheed P-3 Orions.
