World War I Organized in France on 4 April 1918, the
Photographic Section No. 1 processed aerial photographs taken by flying units working with the
I Corps Observation Group and the French 38th Army Corps, 5 April–November 1918.
Inter-war years After moving back to the United States in June 1919, the unit was demobilized in July. In September 1919 the unit was organized as the
1st Photographic Section, assigned to the 1st Wing and then the
1st Surveillance Group, where they processed aerial photography for associated observation squadrons in Texas until becoming the
3rd Observation Squadron on June 1, 1937.
World War II At
Langley Field, Virginia, the squadron engaged in aerial observation work attached to the Coast Artillery School using
Bell P-39 Airacobras until April 1942. It supported ground forces on maneuvers during 1942, and served as a training and demonstration unit January 1943 – February 1944. The squadron was not manned or equipped, 1 Mar – 2 July 1944, and was disbanded in July.
Strategic Reconnaissance Activated again on 28 May 1952 under
Strategic Air Command as part of its global reconnaissance mission and known as the 3rd Strategic Reconnaissance Squadron. The squadron did not receive its first aircraft until 1 July 1953, when it immediately began familiarization training, followed by in-flight refueling training in February 1954. It received
Boeing RB-47E Stratojet aircraft in March 1954, and conducted its first long-range mission (6 planes to Alaska for 10 days) in May 1954. The squadron deployed at RAF Upper Heyford, England, 14 September – 3 November 1954. Some of these flights were mounted from
Thule in Greenland and probed deep into the heart of the Soviet Union, taking a photographic and radar recording of the route attacking SAC bombers would follow to reach their targets. Flights which involved penetrating mainland Russia were termed SENSINT (Sensitive Intelligence) missions. One RB-47 even managed to fly 450 miles inland and photograph the city of
Igarka in Siberia. It photographed numerous Air Force bases and American cities, 1954–1958, and participated regularly in SAC exercises. Missions flown on a reduced scale after February 1958 when events showed the vulnerability of the RB-47 to Soviet
air defenses and the development of the U-2 aircraft. It slowly became non-operational between 15 April and 1 July 1958 until inactivation in July 1958.
Vietnam War On 1 May 1968, it was organized as the
3rd Air Commando Squadron at
Nha Trang Air Base, South Vietnam, absorbing resources of the
14th Air Commando Squadron. It flew combat missions in
Douglas AC-47D gunships in close air support of ground forces, providing flare illumination and gunfire in support of strategic hamlets, outposts and friendly forces under night attack. From 16 February – 1 May 1969, all squadron aircraft were maintained on ground alert when not flying, due to the
Tet Offensive. It began transferring its gunships to the
Republic of Vietnam Air Force in June 1969 and flew its last mission on 7 August 1969.
Electronic warfare training On 15 May 1976, it was reactivated as the
3rd Tactical Electronic Warfare Training Squadron, and was not equipped with aircraft, operating out of
Camp O'Donnell, Philippines, the Pacific Air Forces Electronic Warfare Range, the Crowe Valley Aerial Gunnery Range, and associated facilities. It provided realistic conventional, tactical, and electronic warfare training in a simulated combat environment during
Cope Thunder exercises. These exercises provided combat training for fighter aircrews of the U.S. Marine, U.S. Navy, and allied air forces in the western Pacific area. Following the
eruption of Mt. Pinatubo in June 1991, personnel were evacuated, and the squadron remained unmanned until its inactivation, on 30 September 1991.
Special operations On 28 October 2005, the 3rd was reactivated as the
3rd Special Operations Squadron. The initial cadre of squadron members attended training in the spring and summer of 2005. The 3rd SOS flew
MQ-1B UCAVs. Despite the lack of personnel the 3rd SOS flew 23% of the total Combined Force Air Component Command MQ-1 Predator hours for the last two months of 2005. In 2005, the 3rd SOS supported the combatant commanders in both
Operation Iraqi Freedom and
Enduring Freedom. They logged 650 combat sorties in Afghanistan and 4,243 sorties in Iraq. The hours totaled over 14,000 for the combined theaters. During 2007, the 3rd SOS doubled in size and tripled its combat capabilities. The squadron became the largest MQ-1B squadron in the Air Force within 20 months of its inception. The 3rd SOS has become the "base-line"
Remotely Piloted Aircraft for the
Air Force Special Operations Command. ==Lineage==
