1st Marine Aircraft Wing

The 1st Marine Aircraft Wing is an aviation unit of the United States Marine Corps that serves as the Aviation Combat Element of the III Marine Expeditionary Force. The wing is headquartered at Camp Foster on the island of Okinawa, Japan. Activated in 1940, the wing has seen heavy combat operations during World War II, the Korean War, and the Vietnam War.

Conduct air operations in support of the Fleet Marine Forces to include offensive air support, antiair warfare, assault support, aerial reconnaissance including active and passive electronic countermeasures (ECM), and control of aircraft and missiles. As a collateral function, the Wing may participate as an integral component of Naval Aviation in the execution of such other Navy functions as the Fleet Commander may direct.

As of January 2025 the 1st Marine Aircraft Wing consists of four subordinate groups, a headquarters squadron and a liaison unit:

In late 1940, Congress authorized a naval air fleet of fifteen thousand aircraft. The Marine Corps was allotted a percentage of these planes to be formed into 2 air wings with 32 operational squadrons. On the advice of Navy and Marine advisors returning from observing the war in Europe these numbers were doubled very soon after. It was under this expansion program that the 1st Marine Aircraft Wing was activated at Marine Corps Base Quantico, Virginia, on 7 July 1941. The First Marine Aircraft Group which was the largest east coast aviation unit in the Marines at the time, became its first component. Although a new wing, it is considered an unofficial descendant of the Northern Bombing Group of World War I.

Following the attacks on Pearl Harbor, the wing transferred to Naval Air Station San Diego, California, on 10 December 1941, and then to Camp Kearny on 31 December. The first deployment for 1st MAW came in August 1942 when forward elements of the Wing arrived on Guadalcanal and made up the Cactus Air Force supporting the 1st Marine Division during the Battle of Guadalcanal.

At the beginning of the Korean War, the initial deployment of Marines was a provisional brigade activated on 7 July 1950 — the 1st Provisional Marine Brigade — formed from the 1st Marine Division and the 1st Marine Aircraft Wing. Its core consisted of two units — a regimental combat team from the 5th Marine Regiment and Marine Aircraft Group 33 (MAG-33). Their job was to provide close air support, resupply, and Medevac for Marine ground forces.

In late-June 1952, 75 aircraft from 1st MAW participated in the attack on the Sui-ho Dam which were strikes aimed at the hydroelectric plants in North Korea. The Wing's Chief of Staff Frank Schwable was shot down in July 1952 and while a prisoner of war confessed to having participated in germ warfare. He was eventually cleared of all charges, but his case prompted a review of training and expectations of prisoners-of-war.

Two 1st MAW aircraft groups, MAG-33 and MAG-12, and the 1st Antiaircraft Artillery Gun Battalion served during the course of the war. The wing flew 127,496 sorties of which over 40,000 were close air support and Marine helicopters evacuated more than 9,800 wounded personnel
