Patrol Squadron Nine (VP-9) was established at NAS Whidbey Island, Washington, on 15 March 1951. Equipped with the P4Y-2 Privateer (below), VP-9 deployed to Kodiak, Alaska, only four months later. By 1952, the squadron was home-based at NAS Alameda, California.
In June 1952, VP-9 deployed to Iwakuni, Japan, from where it patrolled the seas around Korea. The squadron detached several P4Ys to Korea to drop parachute flares to illuminate North Korean roads, bridges, supply depots, and convoys for attacking Marine Corps aircraft.
Returning to Alameda in January 1953, VP-9 transitioned to the P2V-5 Neptune. During the 1950s, VP-9 deployed to Atsugi and Iwakuni, Japan, and twice to Kodiak. During the 1955 Kodiak deployment, one of the squadron's P2Vs was shot up off Siberia by a Soviet MiG-15 jet fighter and crash-landed on St. Lawrence Island in the Bering Sea; several crew members were wounded, but none was killed. Transition to the P2V-7 version followed later that year. During the 1958 Kodiak deployment, VP9 crews assisted the Nautilus (SSN-571) on its historic passage under the polar ice cap.
