World War IIEdit

Marine Air Support Squadron 2 was activated 1 January 1943, at Marine Corps Air Station El Centro, California, as Headquarters Squadron 43, Services Group, Marine Wings Pacific. The unit originally functioned as the headquarters element of Marine Aircraft Base Defense Group 43. In November 1944, the Group was assigned to Marine Aircraft Group 43. During the first two years of its existence the Squadron remained in California. With the departure of the Group, however, Headquarters Squadron 43 also moved to Hawaii. While deployed to the territory of Hawaii in January 1945, Headquarters Squadron 43 and Marine Aircraft Group 43 were reassigned to the 2nd Marine Aircraft Wing.

The stay in Hawaii was only of a brief duration, because on 22 February 1945, Headquarters Squadron 43 embarked and sailed on board the USS Allendale for the Western Pacific. Marine Aircraft Group 43 was designate to be in charge of the air defense fight in the forthcoming Battle of Okinawa. Its mission was first to occupy Japanese airfields and then to aid in furnishing of aerial defense for ground troops. Upon landing, the Squadron assumed the responsibility of assisting in the development and operation of air warning and fighter direction facilities within the Air Defense Command. During the course of the battle the unit was located about 1 km southeast of Yontan Airfield and was subjected to nearly nightly Japanese Air Raids. Five enlisted Marines from the unit were killed on April 20, 1945 when a Japanese plane dropped a bomb on the mess tent. For its service during the battle for the island, the Squadron was awarded the Presidential Unit Citation.

On 1 August 1945, Headquarters Squadron 43 was re-designated as Headquarters Squadron, Marine Air Defense Command 2 (MADC-2). Headquarters Squadron was reassigned in February 1946 to the 4th Marine Aircraft Wing and was reassigned to Air Fleet Marine Force, Pacific in March 1946 and relocated to San Diego, California in April 1946. On 1 August 1946, the unit was designated as Headquarters Squadron, Marine Air Control Group 2 and relocated to Marine Corps Air Station Santa Ana, California in September of the same year.

Korean WarEdit

Marine Tactical Air Control Squadron 2 participated in action during the Korean War at the Battle of Pusan Perimeter, Battle of Inchon, Battle of Chosin Reservoir, the East Central Front, and the Western Front.

Upon arrival at Kobe, Japan on August 1, 1950 the air support section of the squadron sailed for Pusan to control close air support missions for the 1st Provisional Marine Brigade. Three days later, on 4 August, the Air Support Section entered Korea, and assumed control of all close air support aircraft for the 1st Provisional Marine Brigade engaged on the Pusan perimeter. The air defense section remained in Japan; it set up operations at Itami Air Force Base, Honshu, Japan to be co-located with VMF(N)-513.[1] For the Inchon invasion, both sections of MTACS-2 departed their respective locations and headed for the new front. On 17 September, the squadron disembarked at Inchon. The air support section aided the 1st Marine Division by enabling close air support throughout the battle. The air defense section provided air defense surveillance against possible enemy air intrusion. When the 1st Marine Division sailed for Wonsan, both the Air Support and defense sections of MTACS-2 sailed with them. Upon arrival at Wonsan, the Air Support section debarked on October 26, 1950, establishing the TADC on Wonsan Airfield, The Air Defense section moved to nearby Hamhung and was joined by the TADC on 6 November 1950. The Air Support section was with the 1st Marine Division from November 27 - December 10, 1950 during the Battle of Chosin Reservoir. They controlled the flow of aircraft in support of the division and also manned a portion of the western perimeter at Hagaru-ri where the Division Headquarters was located.[2]

After the successful breakout of the Chosin Reservoir, the Air Support section was transported to Masan, on the southern coast of Korea. The Air Defense section remained aboard ship and sailed for Pusan, Korea and set up the TACC for operation at Pusan West AB (K-1). In August 1951, the Marine Air Support Radar Team 1 arrived from CONUS and was attached to MTACS-2. In March 1952, the Air Support section moved with the 1st Marine Division to the western front near Panmunjum. The Air Defense section continued to operate the TACC of the 1st Marine Aircraft Wing from its location at K-3 Airfield. The Squadron remained in Korea for the rest of the war until the Truce was signed in July 1953. During the period July 1953 to July 1956, Marine Tactical Air Control Squadron 2 participated in the defense of the Korean Demilitarized Zone. Approximately 6 months after the signing of the Korean armistice, on 15 February 1954, Marine Tactical Air Control Squadron 2 was re-designated as Marine Air Support Squadron 2 (MASS-2).

Vietnam WarEdit

MASS-2 was relocated and operated in the Republic of Vietnam from 1965 to 1969. Early in April 1965 the Squadron was alerted for deployment to Vietnam. While in Vietnam, MASS-2 conducted operations at Da Nang, Chu Lai, Quang Ngai, Marble Mountain, Phu Bai, Dong Ha, Camp Carroll, and Signal Hill, as well as other locations. The squadron redeployed to Iwakuni, Japan, in 1969 and, in 1973, became home-based at MCAS Futenma, Okinawa. MASS-2, operating as an agency of the Marine Air Command and Control System of the 1st Marine Aircraft Wing, supports the III Marine Expeditionary Force by providing DASC and ASRT combat support to all Marine Air-Ground Task Forces in the Western Pacific

Global War on TerrorEdit

Personnel from MASS-2 have augmented other units deploying to Afghanistan in support of Operation Enduring Freedom. They have also provided Marines for the 31st Marine Expeditionary Unit which has deployed to Iraq in support of Operation Iraqi Freedom.
