Patrol Squadron 11 is a former United States Navy patrol squadron. VP-11 was formally established on 1 July 1941, flying the PBY-1 and operating from NAS Kaneohe, Hawaii. During the attack on Pearl Harbor the majority of the squadron’s aircraft were destroyed or damaged beyond repair. Losses were replaced in April 1942 with new PBY-5 seaplanes. VP-11 crews operated throughout the Western Pacific, and from September 1943 through the end of the war, they flew the PBY Catalina flying boats as part of the famed Black Cat operations. On 1 October 1944 they were redesignated VPB-11 and disestablished on 20 June 1945, following the war. On 15 May 1952, VP-11 was re-established at NAS Quonset Point, Rhode Island; flying the Consolidated Vultee PB4Y-2 Privateer and later the Lockheed P2V-5 Neptune.
