Marine Observation Squadron 6 (VMO-6) was an observation squadron of the United States Marine Corps which saw extensive action during the Battle of Okinawa in World War II and the Korean and Vietnam Wars. The squadron was the first Marine Corps helicopter squadron to participate in combat operations when it participated in the Battle of Pusan Perimeter in August 1950.[1] The squadron was decommissioned on 1 January 1977.
History
Early years
Flight E, 3d Air Squadron was commissioned on 1 December 1920 at Marine Corps Air Station Quantico, Virginia. The name of the squadron changed to Division 1, VF-1M on 24 August 1922 and again to Division 1, VO-3M on 1 September 1925.[2] In 1927 they were re-designated Marine Observation Squadron 6 (VO-6M). In 1928, while flying the Curtiss F8C-1 Falcon they deployed aboard the USS Saratoga, from which they fought the Sandinistas in Nicaragua. During this time the Squadron also flew the Atlantic TA-1 and TA-2. In 1928 they returned to MCB Quantico where they took up the role of doing flight demonstrations for new officers at The Basic School.
During the 1930s VO-6M flew the VoughtVought 02U-1 and the CurtissF8C-5 Helldiver. Calling themselves the "Helldivers", in 1932 they were representing the Marine Corps at major events such as the Canadian Air Pageant and the US National Air Races in Cleveland, Ohio.[3] During this time the Marines took on the mission of defending advanced naval bases and the Commandant of the Marine Corps recommended a light bombing squadron be activated in 1934. This required the deactivation of an observation squadron so VMO-6 was deactivated on 30 June 1933.
On 1 April 1945, VMO-6 came ashore during the Battle of Okinawa and commenced operations from Yomitan Airstrip. VMO-6 flew its OY-1 aircraft on a variety of missions, including artillery spotting, message pickups, photo reconnaissance and medical evacuations in litter equipped OY-ones. In July 1945, the squadron departed for Agaña, Guam where it remained until the end of the war.[4] In October 1945, VMO-6 was deployed to Tientsin, China to participate in the occupation and because of the increase in communist activity. The squadron served in a variety of liaison roles and flew very dangerous missions often under intense ground fire from the communist forces. They finally left China on 3 January 1947 and returned to MCB Pendleton.[5]
Korean War
In August 1950, HO3S-1 helicopters and pilots from HMX-1 at MCAF Quantico, Virginia joined the squadron's eight OY-2 Sentinels and VMO-6 departed the United States in July 1950 as part of Marine Aircraft Group 33.[6] They arrived in Jinhae, Korea on 2 August[7] and immediately began to fly during the Battle of Pusan Perimeter becoming the first helicopter squadron in the Marine Corps to participate in combat operations[8] The OY-2's were flown as convoy escorts for the 1st Marine Brigade in addition to observation and reconnaissance missions. They proved so successful that it became regular procedure to have an OY over the brigade at all times during daylight hours.[9] In August 1950 the squadron, carried its first medevac and these missions became routine for VMO-6 pilots and crewmen. On 27 November 1950, Chinese encircled the 1st Marine Division at the Battle of Chosin Reservoir. For the first four days of the battle, until an expeditionary airfield was completed at Hagaru-ri on 1 December, helicopters from VMO-6 were the only aircraft able to evacuate the wounded taking 152 injured south to Hungnam. The next ten days would see them evacuate a further 538 aided by modified TBM Avengers that belonged to the Division.[10] During the Korean War, the squadron conducted 22,367 missions and flew 7,067 wounded Marines to safety.[11] After the signing of the Korean Armistice Agreement the squadron returned to MCB Camp Pendleton in June 1955. In 1951, the squadron replaced the HO3S-1 with the HTL-4.[12]
Cold War
On 20 March 1956 VMO-6 became the first Marine Corps squadron to receive the HOK-1 helicopter.[13]
