Patrol Squadron 40 (VP-40) is a United States Navy maritime patrol squadron that has operated long-range patrol aircraft in anti-submarine warfare, intelligence, surveillance, reconnaissance, and anti-surface warfare missions. Established during World War II, the squadron has a lineage tied to carrier-based patrol operations, fleet cooperation with United States Pacific Fleet, and deployments supporting NATO and CENTCOM tasking. VP-40 has transitioned through multiple airframes and basing assignments while participating in operations associated with Aleutian Islands Campaign, Korean War, and post-9/11 maritime security efforts.

History

VP-40 traces origins to patrol units formed in the 1940s and has undergone redesignations and reassignments aligning with Naval Aviation reorganizations, reflecting shifts in doctrine from piston-engine patrol bombers to turboprop maritime patrol aircraft. During World War II, the squadron supported convoy escort and anti-shipping patrols in the Pacific Ocean theater, contributing to operations near the Aleutian Islands and the Gilbert and Marshall Islands campaign. In the Cold War era VP-40 conducted long-range surveillance of Soviet naval movements, cooperating with the United States Pacific Fleet, Antarctic resupply missions tied to Operation Deep Freeze, and coordinated ASW operations with units from the Royal Navy and Royal Australian Navy. In the late 20th and early 21st centuries, the squadron supported Operation Desert Storm, Operation Enduring Freedom, and Operation Iraqi Freedom, providing intelligence, surveillance, and reconnaissance for carrier strike groups, amphibious forces, and multinational task forces.

Aircraft and Equipment

Over its history the squadron operated a succession of patrol aircraft reflecting technological advances in maritime patrol: early piston types like the Consolidated PBY Catalina and PB4Y-2 Privateer; Cold War twins such as the Lockheed P-2 Neptune and Lockheed P-3 Orion series; and later upgrades including the P-3C Orion with Tactical Air Reconnaissance Pod System and advanced acoustic processing suites. VP-40 integrated sonobuoy systems, magnetic anomaly detectors, electro-optical/infrared sensors, and signals intelligence gear interoperable with SOSUS and Fixed-wing ASW networks. Training and maintenance incorporated logistics from Naval Air Systems Command and mission planning linked to Maritime Patrol and Reconnaissance Force tactics, techniques, and procedures.

Home Ports and Deployments

The squadron’s home ports have included Naval Air Station Whidbey Island, Naval Air Station Jacksonville, and temporary detachments to forward locations such as Andersen Air Force Base in Guam, Naval Air Station Keflavik in Iceland, and Diego Garcia in the Indian Ocean. Deployments supported carrier strike groups operating from USS Nimitz (CVN-68), USS Kitty Hawk (CV-63), and other Atlantic and Pacific fleet carriers, while bilateral exercises saw VP-40 operating with units from Japan Maritime Self-Defense Force, Canadian Forces Maritime Command, and Republic of Korea Navy maritime patrol squadrons. Patrol sectors frequently covered the North Pacific, South China Sea, Gulf of Aden, and the Mediterranean Sea.

Insignia and Traditions

The squadron emblem, the Fighting Marlins motif, reflects maritime striking capability and seafaring heritage; the insignia evolved under approval from Chief of Naval Operations heraldry standards and displays colors similar to other Patrol squadrons bearing blue and gold. Traditions include ceremonial cross-covers, crew lineages honoring World War II veterans, and adoption of maritime folklore aboard squadron aircraft during long-range patrols. Unit rituals mirror Naval Aviation ceremonial practices, including aircraft rollouts with squadron pennants and presentations at Fleet Week ceremonies and anniversary observances tied to squadron commissioning dates.

Notable Operations and Engagements

VP-40 elements have been involved in ASW barriers and convoy protection during World War II Pacific operations, surveillance and interdiction during Korean War maritime campaigns, and heightened maritime domain awareness during the Cold War against Soviet submarine activity. During Operation Desert Storm and subsequent Operation Southern Watch patrols, the squadron provided overland reconnaissance and anti-surface surveillance supporting coalition naval and air operations. In the 21st century VP-40 forces contributed to counter-piracy patrols in the Gulf of Aden, overwater ISR for Operation Enduring Freedom logistics routes, and cooperative deployments under Combined Task Force 150 and Combined Task Force 151 mission sets.

Unit Honors and Awards

Throughout its service the squadron has received unit commendations and awards recognizing operational excellence, safety milestones, and combat support, including Navy Unit Commendation, Meritorious Unit Commendation, and campaign streamers for World War II and later conflicts. Individual aircrew and maintenance personnel have been decorated with Air Medal, Navy Commendation Medal, and other personal awards for meritorious flight operations and combat missions while assigned to the squadron. The unit’s safety record and maintenance achievements have been recognized with prizes and citations from Commander, Patrol and Reconnaissance Group and fleet commanders.
