Service history
Active 25 Sept 1943 – Feb 46
Role Aerial surveillance & early warning

Air Warning Squadron 2 (AWS-2) was a United States Marine Corps aviation command and control squadron during World War II. The squadron was tasked to provide aerial surveillance and early warning during amphibious assaults. They took part in the Battle of Guam in 1944 and would eventually move to Peleliu in 1945 assuming responsibility for air defense in that sector until the end of the war.


(Primary) – Operation in the Pacific Ocean Area. To furnish early warning information on approaching air and sea attack and to furnish fighter direction against this attack.

(Secondary) – Participation in the local defense when released to the operational control of the Hawaiian Sea Frontier and/or the Seventh Army Air Force Fighter Command


Air Warning Squadron 2 was commissioned on 25 September 1943 at Marine Corps Air Station Cherry Point, North Carolina. At commissioning the squadron consisted of 8 officer and 146 enlisted men. Because it was one of the first two air warning squadrons formed in the Marine Corps during the war its early training was severely hampered by personnel and equipment shortages. Prior to deploying overseas the only gear available to the squadron was shared with the rest of air warning group. They also spent the month of October 1944 at Marine Corps Auxiliary Airfield Oak Grove, North Carolina conducting operational training.

AWS-2 was detached from MCAS Cherry Point on 10 November 1943 and ordered to proceed to the West Coast. The squadron finally received a portion of its own gear just prior to departing San Diego. The partially equipped squadron arrived at Marine Corps Air Station Ewa, Hawaii on 9 January 1944 with 14 officers and 219 enlisted men.

Additional equipment was received at MCAS Ewa and the squadron was able to complete calibration flights by the end of the month. Operational training for men and equipment started with simulated field conditions for area aircraft-warning coverage and fighter direction to portect the area from day and night bomber attack. This lasted until April. During this time AWS-2 also assisted with various air-warning and tower control units in the Hawaiian area with communications checks, relaying of messages and homing lost planes. On 16 May 1944, 4 officers and 64 enlisted men were transferred to the III Amphibious Corps at Guadalcanal, and formed an air-warning assault echelon. The rest of the squadron departed Hawaii on 1 June 1944. Both echelons were headed for Guam. This assault echelon landed on Guam on 21 July 1944 and three days later the first Marine radar set reported on the air. The larger portion of the squadron arrived 27 July 1944 with the final Marines arriving from Ewa on 10 August 1944. A week later their SCR-270 radar was operational. The squadron operated two long range search radars (SCR-270s) and one ground controlled intercept (GCI) radar (SCR-527) and an air defense control center which received information from additional reporting radars on Guam and in the Marianas area. During this time they were responsible for supplying air warning and fighter direction against air and sea attacks for the Air Defense Command of Guam and the Marianas Islands. In December the squadron started experiments with window and by February 1945 they were practicing with pilots in practice day fighter interception tactics. Early in March 1945 AWS-2 Marines were sent to Ulithi and Peleliu to prepare facilities on those islands as portions of AWS-2 would be relieving United States Navy ARGUS units of their air defense responsibility.

By early May 1945 the squadron headquarters was formed at Peleliu with detachments on Ulithi and Falalop. AWS-2 was responsible for air defense of this region until the end of the war. The squadron returned to the United States in February 1946 and was quickly decommissioned.
