The 70th Intelligence, Surveillance and Reconnaissance Wing (70th ISR Wing) is a United States Air Force unit assigned to the 16th Air Force. It is stationed at Fort George G. Meade, Maryland.

Known as "America's Cryptologic Wing", is the only Air Force wing that supports the National Security Agency, the Sixteenth Air Force, and the entire United States Air Force with cryptologic intelligence.

The 70th Reconnaissance Group conducted observation, artillery adjustment and fighter and bomber support training with United States Army ground forces during World War II. The group served as a reserve unit for two years later in the decade. During the Cold War, the 70th was a component wing of Strategic Air Command's (SAC) deterrent force as a strategic reconnaissance organization and heavy bombardment wing.

The wing's mission is to provide multi-source, multi-service intelligence products for the Department of Defense (DoD) by gaining and exploiting information as a major component of the Air Force and DoD global intelligence mission. It trains and equips cryptologic and information operations specialists to carry out Air Force ISR Agency and National Security Agency joint-service operations.

The wing has six groups, 19 squadrons, 10 detachments and 26 operating locations spanning four continents. The wing falls under the Sixteenth Air Force at Lackland Air Force Base, Texas.

543d Intelligence, Surveillance and Reconnaissance Group is based at the Medina Annex, Lackland Air Force Base, Texas. A unique group within the wing. Organized according to mission, rather than by geography, the 543rd ISR Group has two squadrons within the United States that are part of Regional Signals Intelligence (SIGINT) Operations Centers. Providing command and control, personnel, communications, computer and logistics support for all Regional SIGINT Operations Centers conducting information operations, the 543rd ISR Group provides timely and accurate multi-regional SIGINT to warfighters and other intelligence users.

Component units

Unless otherwise indicated, units are based at Fort George G. Meade, Maryland, and subordinate units are located at the same location as their commanding group.[1]


The 70th ISR Wing has its origins in the World War II 70th Reconnaissance Group, which was activated at Gray Army Airfield in September 1941.[2] The 70th Reconnaissance Group was originally a Fourth Air Force training unit in observation and artillery adjustment, supporting Army ground units at Fort Lewis.[citation needed] After the Pearl Harbor Attack, the unit began antisubmarine patrols along the Pacific Coast,[2] and provided support to II Bomber Command heavy bomber training units. It was largely unmanned after August 1943 when the United States Navy took over antisubmarine duty.[citation needed]

The group moved to Will Rogers Field, Oklahoma under Third Air Force in November 1943,[2] and was programmed for training as a photo-reconnaissance unit, but the unit was never manned or equipped and was inactivated 30 November 1943.[citation needed]

The group was reactivated as part of the Air Force Reserve in 1947 as a reconnaissance group at Hill Air Force Base, Utah.[2] It was assigned to Fourth Air Force, but it is unclear whether or not the unit had any assigned aircraft or personnel. It was inactivated in 1949 when Continental Air Command converted its reserve units to the Wing-Base organizational system (Hobson Plan).

Strategic Reconnaissance

The 70th Strategic Reconnaissance Wing was established by SAC on 23 March 1953, at Little Rock Air Force Base, Arkansas. However, Little Rock AFB was still under construction at the time, so the unit was temporarily stationed at Lockbourne Air Force Base, Ohio until October. Few wing components were manned until October when Little Rock was ready for operational use.[3]

The 70th SRW's mission was to gather intelligence on a global scale as part of the strategic reconnaissance force of SAC.[3] Equipped with Boeing RB-47E Stratojets, the wing conducted a variety of spectacular overflights of the Soviet Union during the 1950s, including overflying Murmansk. RB-47s had a fairly low operational ceiling of 40,000 feet and relied on speed, as opposed to altitude, to evade interception. Some of these flights were mounted from Thule, 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. The risks involved in mounting these dangerous sorties speaks volumes for the courage and skill of the crews involved. Flights that 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.[citation needed]

The 70th SRW also assumed an air refueling mission in 1955 and was deployed at Sidi Slimane Air Base, Morocco, from 26 October to 17 December 1956.[3]

Beginning in February 1958, operations with the RB-47 were reduced,[3] primarily as the aircraft was determined to be vulnerable to Soviet air defenses, but also its mission was being taken over by the Lockheed U-2.[citation needed] From June 1958 to September 1961, the wing became a B-47 bombardment and reconnaissance organization, providing B/RB-47 combat crew training for other SAC units, while undertaking RB-47 and Boeing KC-97 Stratofreighter operations. The refueling squadron transferred in August 1961, and the final RB-47 class graduated in October 1961. It converted to B-47s in late 1961 but inactivated prior to becoming combat ready.[3]

Strategic bombardment

4123d Strategic Wing On 10 December 1957, SAC established the 4123d Strategic Wing (SW) at Carswell Air Force BaseTexas[4] and assigned it to the 19th Air Division.[5] The wing was assigned the 4123d Air Base Squadron, which had been the host unit at Clinton-Sherman Air Force Base, Oklahoma since July 1955, preparing Clinton-Sherman, a former World War II Naval Air Station, to receive operational SAC aircraft plus the 98th Bombardment Squadron (BS), consisting of 15 Boeing B-52 Stratofortresses, which had been one of the three squadrons of the 7th Bombardment Wing[6] and a maintenance squadron[4] at Carswell. The air base squadron was expanded into the 4123d Air Base Group and assigned component squadrons on 1 July 1958.

At the end of 1958, the wing's first operational squadron, the 902d Air Refueling Squadron, flying Boeing KC-135 Stratotankers, was activated at Clinton-Sherman and the wing moved its headquarters to the base on 25 February 1959 and was reassigned to the 816th Air Division at the beginning of March.[7] Within a week the 98th Bombardment Squadron joined the wing at Clinton-Sherman as part of SAC's plan to disperse its Boeing B-52 Stratofortress heavy bombers over a larger number of bases, thus making it more difficult for the Soviet Union to knock out the entire fleet with a surprise first strike.[8] The same month, the 55th Aviation Depot Squadron was activated to oversee the wing's special weapons. Starting in 1960, one third of the wing's aircraft were maintained on fifteen-minute alert, fully fueled, armed and ready for combat to reduce vulnerability to a Soviet missile strike. This was increased to half the wing's aircraft in 1962.[9] The 4123d (and later the 70th) continued to maintain an alert commitment until inactivation. In 1962, the wing's bombers began to be equipped with the GAM-77 Hound Dog and the GAM-72 Quail air-launched cruise missiles, The 4123d Airborne Missile Maintenance Squadron was activated in November to maintain these missiles

However, SAC Strategic Wings could not carry a permanent history or lineage and SAC looked for a way to make its Strategic Wings permanent.

70th Bombardment Wing Patch

70th Bombardment Wing

In 1962, in order to perpetuate the lineage of many currently inactive bombardment units with illustrious World War II records, Headquarters SAC received authority from Headquarters USAF to discontinue its Major Command controlled (MAJCON) strategic wings that were equipped with combat aircraft and to activate Air Force controlled (AFCON) units, most of which were inactive at the time which could carry a lineage and history.[10] As a result, the 4123d SW was replaced by the newly redesignated 70th Bombardment Wing, Heavy (70th BW),[3] which assumed its mission, personnel, and equipment on 1 February 1963.[11] In the same way the 6th Bombardment Squadron, one of the unit's B-47 reconnaissance squadrons, replaced the 98th BS.[12] The 857th Medical Group, 55th Munitions Maintenance Squadron and the 902d Air Refueling Squadron were reassigned to the 70th. The 4123d's maintenance and support units were replaced by units with numerical designation of the newly established wing. Under the Dual Deputate organization, all flying and maintenance squadrons were directly assigned to the wing, so no operational group element was activated. Each of the new units assumed the personnel, equipment, and mission of its predecessor.

The 70th BW conducted strategic bombardment training and air refueling missions from February 1963 to December 1969.[3] It was upgraded to the B-52D in 1968 by SAC along with receiving some older B-52Cs, which had limited use for training new aircrews. For several months in both 1968 and 1969, all of the 70th BW aircraft, most of the aircrew and maintenance personnel and some of its support people were loaned to other SAC units engaged in combat operations in the Far East and Southeast Asia.[3] It was one of 11 SAC bomb wings that rotated such combat duty under the program known as Arc Light.

By 1969, Intercontinental ballistic missiles (ICBM) had been deployed and become operational as part of the United States' strategic triad, and the need for B-52s had been reduced. In addition, funds were also needed to cover the costs of combat operations in Indochina. The 70th Bombardment Wing was inactivated 31 December 1969,[3] and its aircraft were reassigned to other SAC units. As part of the inactivation, Clinton-Sherman AFB was closed.

Modern era

The wing was redesignated the 70th Air Base Group and operated and maintained Brooks Air Force Base, Texas from October 1994 until that installation's BRAC-directed closure in September 2011.[13] It supported the Human Systems Center until October 1998, when the Center was redesignated as the 311th Human Systems Wing. The group's mission, personnel, and equipment were all transferred to the 311th Air Base Group.

In August 2000, the unit was activated as the 70th Intelligence Wing, then later the 70th Intelligence, Surveillance, and Reconnaissance Wing, and has managed the USAF portion of the DoD's cryptology mission, exploiting intelligence, integrating it into air and space operations, and assisting commanders and others with intelligence requirements.[13]

The wing's 544th Intelligence, Surveillance and Reconnaissance Group inactivated on 24 July 2020 when it became Space Delta 7 of the US Space Force.[14]
