Marine Air Control Squadron 3 (MACS-3) was a former United States Marine Corps aviation command and control squadron. During its later years it also served as an operational test and evaluation squadron. Originally formed in World War II as Air Warning Squadron 12 (AWS-12), its original mission was to provide aerial surveillance and ground-controlled interception (GCI) for Marine Corps forces during amphibious operations. The squadron did not participate in combat operations during WWII however it did deploy and operate during the Korean War. In 1961, MACS-3 was transferred from the Fleet Marine Force to the administrative control of Air, Fleet Marine Forces Pacific in order to serve as the operational test and evaluation squadron for what was at the time, the largest research and development project in the Marine Corps - Marine Tactical Data System (MTDS). After MTDS testing was complete the Marine Corps recognized that it was not properly staffed to develop, test, and acquire new digital equipment. On 1 July 1970, MACS-3 was decommissioned and its structure and equipment were utilized to form Marine Corps Tactical Systems Support Activity (MCTSSA) at Marine Corps Base Camp Pendleton, California. Of note, MCTSSA does not carry MACS-3's lineage and honors.
Robert O. Bisson was a brigadier general in the United States Marine Corps who served in both World War II and the Korean War. A naval aviator and communications engineer, he was at the forefront of the Marine Corps' use of radar for early warning and fighter direction. In 1943, as a member of VMF(N)-531, he supervised the installation and operation of the Marine Corps' first ground-controlled interception (GCI) equipment utilized in a combat zone. During the Battle of Okinawa he commanded the headquarters responsible for coordinating the Marine Corps' ground-based air defense units.
Air Warning Squadron 3 (AWS-3) was a United States Marine Corps aviation command and control squadron during World War II. The squadron's primary mission was to provide aerial surveillance and early warning of approaching enemy aircraft during amphibious assaults. The squadron participated in the Philippines campaign (1944–1945) in support of the Eighth Army on Mindanao. AWS-3 was decommissioned shortly after the war in October 1945 at Marine Corps Air Station Miramar, California. To date, no other Marine Corps squadron has carried the lineage and honors of AWS-3 to include the former Marine Air Control Squadron 3 (MACS-3).
Assault Air Warning Squadrons were United States Marine Corps aviation command and control units formed during World War II to provide early warning, aerial surveillance, and ground controlled interception during the early phases of amphibious landing. These squadrons were supposed to be fielded lightweight radars and control center gear in order to operate for a limited duration at the beginning of any operation until larger air warning squadrons came ashore. Four of these squadrons were commissioned during the war with one, AWS(AT)-5, taking part in the Battle of Saipan. All four squadrons were decommissioned on 10 November 1944 because the Marine Corps was unable to field the required mobile radars. The "first in" capability that the Assault Air Warning Squadrons were supposed to provide was transferred to the Early Warning Teams that were added to the tables of organization for the regular air warning squadrons.
The Tactical Air Force, Tenth Army (TAF) was a joint aviation command of the Tenth United States Army that was responsible for commanding all land-based aviation and aviation command and control units during the Battle of Okinawa. The TAF's headquarters was provided by the 2nd Marine Aircraft Wing and it was the largest joint aviation unit under Marine Corps command during World War II. During the battle, the TAF was commanded by Major General Francis P. Mulcahy until ill-health forced him to be relieved by MajGen Louis E. Woods. According to United States sources, TAF aircraft were responsible for shooting down 637 Japanese aircraft during the battle.
Marine Aircraft Group 43 (MAG-43) was a fixed wing aviation group in the United States Marine Corps Reserve based at Naval Air Station Joint Reserve Base Willow Grove, Pennsylvania.
Air Warning Squadron 4 (AWS-4) was a United States Marine Corps aviation command and control squadron during World War II. The squadron's primary mission was to provide aerial surveillance and early warning of approaching enemy aircraft during amphibious assaults. The squadron participated in the Philippines campaign (1944–1945) in support of the Eighth Army on Mindanao. AWS-4 was decommissioned shortly after the war in October 1945. To date, no other Marine Corps squadron has carried the lineage and honors of AWS-4 to include Marine Air Control Squadron 4 (MACS-4).
Air Warning Squadron 9 (AWS-9) was a United States Marine Corps aviation command and control squadron during World War II. The squadron's primary mission was to provide aerial surveillance and early warning of approaching enemy aircraft during amphibious assaults. Formed in April 1944, the squadron did not deploy overseas until after the end of the war. It arrived in Tokyo Bay to take part in the occupation of Japan only to find out it was not required. The squadron returned to the U.S. and was decommissioned shortly after in December 1945. To date, no other Marine Corps squadron has carried the lineage and honors of AWS-9 to include the former Marine Air Control Squadron 9 (MACS-9).
Air Warning Squadron 14 (AWS-14) was a United States Marine Corps aviation command and control squadron during World War II. The squadron's primary mission was to provide aerial surveillance and early warning of approaching enemy aircraft during amphibious assaults. Formed in June 1944, the squadron was one of a handful of air warning squadrons that was never able to deploy overseas during the war. The squadron was decommissioned shortly after the end of the war in November 1945. To date, no other Marine Corps squadron has carried the lineage and honors of AWS-14 to include the former reserve Marine Air Control Squadron 14 (MACS-14).
The VMF(N)-531 GCI Detachment was a short-lived aviation command and control unit that was part of the United States Marine Corps's first night fighter squadron, VMF(N)-531. This detachment was the Marine Corps' first dedicated GCI detachment utilized in a combat zone. In the early phases of World War II the Marine Corps did not have stand-alone early warning and ground-controlled intercept (GCI) units so these capabilities were initially placed in the headquarters of each Marine Aircraft Group and with individual night fighter squadrons. The detachment was deployed in the South Pacific from August 1943 through August 1944 and was responsible for the interception of numerous Japanese aircraft. Lessons learned from this deployment were instrumental in establishing tactics and procedures for the Marine Corps' newly established Air Warning Program. Upon returning from its first and only deployment, the detachment was dissolved and its members went on to serve as instructors at the 1st Marine Air Warning Group, which was responsible for training new squadrons. Many of them later served in leadership roles in these Air Warning Squadrons as they supported follow on combat operations.
The Marine Corps Early Warning Detachment, Guadalcanal (1942–43) was a ground based early-warning radar detachment that provided long range detection and rudimentary fighter direction against Japanese air raids during the Battle of Guadalcanal. Initially deployed as part of the headquarters of Marine Aircraft Group 23, this detachment established an SCR-270 long range radar that allowed the Cactus Air Force to husband its critically short fighter assets during the early stages of the battle when control of the island was still very much in doubt. The detachment arrived on Guadalcanal on 28 August 1942, began operating in mid-September, and did not depart until early March 1943. Combat lessons learned from this detachment had a great deal of influence on the Marine Corps' development of its own organic, large scale air warning program which began in early 1943.
