Marine Air Control Squadron 2's history dates back to 1 April, 1944 when the Squadron was formed as Marine Air Warning Squadron 11 at Cherry Point, North Carolina, and was attached to Marine Air Warning Group 1, 9th Marine Aircraft Wing. During June 1944, the squadron relocated to Miramar, California and was assigned to Marine Air Warning Group 2. In March 1945, the squadron relocated once again, being assigned to the 3rd Marine Aircraft Wing at Pearl Harbor, Territory of Hawaii. Four months later, Marine Air Warning Squadron 11 joined Marine Aircraft Group 43 of the 2nd Marine Aircraft Wing in Kume Shima, Ryuku Islands. Shortly thereafter, in October 1945, the squadron moved to Tsingtas, China to join Marine Aircraft Group 24, 1st Marine Aircraft Wing, and participated in the occupation of North China until May 1946. Proceeding from North China, the Squadron moved once again to Miramar, California and in August 1946, it was redesignated as Marine Ground Control Intercept Squadron 2, a member of Marine Air Warning Group 2, where it remained until its deactivation on 15 October 1947.
As world attention began to focus upon Communist activity on the Korean Peninsula, Marine Ground Control Intercept Squadron 2 was reactivated in El Toro, California on 3 August 1950. In January 1952, the squadron was attached to Marine Aircraft Group 13 and two months later moved with MAG-13 to Kaneohe Bay, Territory of Hawaii. On 15 February 1954, the Squadron was redesignated as Marine Air Control Squadron 2, and four years later in November 1958, relocated to Atsugi, Japan. In March 1959, MACS-2 joined the First Marine Brigade and returned to Kaneohe Bay, Hawaii. In August 1990, MACS-2 received orders to deploy to Southwest Asia in support of Operation Desert Shield, and on 6 September 1990, arrived in the Kingdom of Saudi Arabia. Establishing a Tactical Air Operations Center (TAOC) in the vicinity of King Abdul Aziz Naval Base (KAANB) , MACS-2 provided a base defense zone for KAANB and the port of Jubayl. On 29 December 1990, MACS-2 displaced to Ras Al Mishab port, harbor, and airfield complex, establishing the primary TAOC eight miles west, to provide anti-air warfare capabilities in support of USMARCENT and I MEF air and ground operations. During Operation Desert Storm in February 1991, an Early Warning and Control (EW/C) site deployed with the ground combat element through the breach to Ahmed Al Jaber airfield in the Kingdom of Kuwait. Upon cessation of hostilities, MACS-2 was redeployed to MCAS Kaneohe Bay, Hawaii in March 1991, in support of Marine Aircraft Group 24, 1st Marine Expeditionary Brigade.
In 1993, MACS-2 relocated to Beaufort, South Carolina, subordinate to Marine Aircraft Group 31. While supporting MAG-31 in 1994, MACS-2 acquired Air Traffic Control Detachments A and B. Also in 1994, MACS-2 deployed in support of exercise Display Determination in Turkey, a NATO exercise involving the integration of foreign military units with American units to include an ATC and EW/C detachment. Between 1995 and 1998, MACS-2 participated in Joint Task Force 6, also known as Operation Lone Star, a drug interdiction operation patrolling the Mexican-American border. Further drug interdiction operations included EC-7 in 1996 in Ecuador and Operation Laser Strike in 1997 conducted in Peru. ATC detachments C and D joined MACS-2 in 1998.
MACS-2 relocated once more to Cherry Point, North Carolina in 1998 under Marine Air Control Group 28 where she resides today. Deployed in support of real world operations, MACS-2 sent an ATC detachment known as a Marine Air Traffic Control Mobile Team (MMT) to Kosovo with the 26th Marine Expeditionary Unit in 1999. In support of the ground war in Serbia, MACS-2 deployed an MMT to the country of Hungary, also in 1999. In 2001, MACS-2 sent TAOC Marines to South-West Asia to support the Air Force in Operation Southern Watch. Current operations include providing an ATC detachment to the Winter Olympics in support of Operation Enduring Freedom. MACS-2 Marines are currently training to provide combat ready, technically and tactically proficient Marines capable of supporting any future contingency.
