The 601st Air Expeditionary Wing is a provisional United States Air Force organization. It was last active as the 601st Air Base Wing with the Seventeenth Air Force at Sembach Air Base, Germany, where it was inactivated on 31 March 1995.


The wing was first activated as the 601st Tactical Control Wing at Sembach in July 1968, when it replaced the 601st Tactical Control Group as the headquarters for Seventeenth Air Force's tactical control units and the 603d Air Base Wing as the host organization for Sembach. For most of its existence, the unit controlled elements of the Tactical Air Control System in Germany. In 1973, the wing moved to Wiesbaden Air Base, but it returned to Sembach in November 1975. Its mission changed in 1992 to supporting Air Force units at Sembach and elsewhere in Germany and it was inactivated in 1995.

The wing was converted to provisional status in February 2001 and assigned to United States Air Forces Europe to activate or inactivate as required, but there have been no reports of its activation as an expeditionary unit.


Through much of its history the mission of the wing was to provide an effective tactical air control system for United States Air Forces in Europe and Allied Air Forces Central Europe. The wing employed a mobile radar network and forward air control flying operations. The wing controlled offensive missions against ground targets and defensive missions for air-to-air intercepts, later interfacing with Airborne Warning and Control System aircraft.


The 601st Tactical Control Group had been activated at Sembach Air Base, Germany in 1965. Its staff was composed of personnel from the former 601st Tactical Control Squadron. The 603d Air Base Wing had provided support to all units at Sembach since September 1966, when the 38th Combat Support Group was inactivated as part of the draw down of the 38th Tactical Missile Wing's CGM-13B Mace missiles in Germany.

The 60lst Tactical Control Wing was organized at Sembach on 1 July 1968. The new wing assumed the missions of the 601st Tactical Control Group and 603d Air Base Wing, which were inactivated. On 14 November 1968, the 86th Air Division at Ramstein Air Base, which controlled United States air defense units in Germany, was inactivated. Three of its aircraft control and warning squadrons were transferred to the wing at the beginning of the month, although the 602d Aircraft Control and Warning Squadron at Giebelstadt was inactivatedn and its mission assumed by a German Air Force radar at Lauda. Detachments of the wing were also organized at fixed radar sites operated by the German Air Force. Another detachment was organized at Ramstein to provide a central maintenance facility for these units.

Fixed radar systems

The long term goal was to transfer operation of the 412L fixed radar sites entirely to German Air Force operation. However, it was not until 1972 that the German Air Force agreed to assume operation of the radar sites at Dobraberg Air Station and Wasserkuppe Air Station. Dobraberg was transferred on 1 July 1974, six months ahead of the agreed date. Maintenance of the remaining site at Wasserkuppe was transferred to a civilian contractor and on 1 January 1979 the Wasserkuppe site was turned over to the German Air Force and the wing's last aircraft control and warning squadron operating a fixed control and reporting post was inactivated. In September 1980 the 412L system was replaced by the German Air Defense Ground Environment system. The 615th Aircraft Control and Warning Squadron continued to operate a combined control and reporting center until 1980, when it was inactivated.

Mobile radar systems

Upgrades to the wing's mobile radars began soon after activation The new two dimensional AN/TPS-44 radar to be used at Forward Air Control Posts became operational in November 1968. In June 1969, wing Control and Reporting Posts accepted their first AN/TPS-43, three dimensional radar. However, problems arose which precluded the upgrades from being completed quickly. Lacking a firm delivery date for the radar to be used for training, Air Training Command could not establish start date for training to begin. Also, an interface kit was required to allow the use of the AN/TPS-43 until the wing received the new AN/TSQ-91V Operations Centrals with were not expected to be delivered until 1971. Radar sites were linked together by AN/TRC-97 wideband radios. This set provided line of sight, point-to-point communications in the German countryside. The AN/TRC-97 was eventually replaced by the digital AN/TRC-170 radio, which required substantially less maintenance.

In 1969 computer programming modifications permitted 4,096 possible transponder codes for friendly aircraft radar identification. This permitted assignment of a unique code to each military aircraft in the Fourth Allied Tactical Air Force region, providing positive identification capability.

In 1976 the 601st Wing expanded its mobile radar coverage to Northern Germany by activating units in the Second Allied Tactical Air Force area of responsibility in Projects Creek North and Creek Control. By year's end, the wing's mobile network grew by 40 percent. The first new sites in this expansion were at Hessisch Oldendorf Air Station, Bad Muender and Schwelentrup. Equipment for these sites came from a tactical control unit at Cannon Air Force Base, New Mexico and from Air National Guard units in Connecticut and Massachusetts.

These first three new sites were a former Royal Netherlands Air Force Hawk missile battery headquarters and two of its satellite missile launch sites. The 609th Tactical Control Squadron and 6l9th Tactical Control Flight were activated at Bad Muender and Schwelentrup respectively on 1 April 1976. A month later, on 1 May 1976, the 629th Tactical Control Flight was also activated at Schwelentrup. A little less than a year later Project Creek Brahman activated three more radar units at Carl Schurz Kaserne near Bremerhaven.

Forward air control

On 15 February 1970, the wing acquired another mission with the arrival of three Cessna O-2A Skymaster aircraft and an airborne Forward Air Control capability. The use of airborne forward air controllers was a new concept of operations for tactical air forces in Europe. The wing was assigned operational control of these aircraft, which flew from Ramstein Air Base, but that the 26th Tactical Reconnaissance Wing would be responsible for their maintenance and ground support. The first operational flight of a wing O-2A occurred on 2 March. Nine days later, the wing deployed its Skymasters to Italy for Operation Dawn Patrol 70. The 0-2s remained at Ramstein until joining the wing at Wiesbaden on 16 July 1973. In October 1973 the Skymasters were organized into the 20th Tactical Air Support Squadron

In July 1974, the 601st Tactical Air Support Squadron (Helicopter) joined the 20th Squadron in the 601st Tactical Air Support Group in preparation for the arrival of Sikorsky CH-53 helicopters. However, the wing's first CH-53C would not arrive until six months later. The wing's first two helicopters arrived on 15 January 1975, and flying operations commenced on 6 February. Five additional CH-53Cs were received during the 1ast two months of the year.

On 21 June 1974, the wing's first two North American OV-10 Bronco aircraft were ferried to Wiesbaden Air Base from Hurlburt Field, Florida, where they were assigned to the 20th Squadron. Flying operations began on 12 July and three months later, on 10 October 1974, the 20th Squadron flew the first OV-10A forward air control mission during Exercise Certain Pledge. Additional OV-10As arrived from Thailand and, on 18 December 1974, O-2A flying operations terminated and the last Skymaster was transferred to the United States Army. Twelve additional OV-l0As arrived at Wiesbaden in August 1975, followed by 10 more two months later.

On 4 July 1976, a second Bronco squadron, the 704th Tactical Air Support Squadron was activated at Sembach. Second, on 1 November 1976, wing OV-10A aircraft, pilots from the 20th TASS, and maintenance personnel from the 601st Consolidated Aircraft Maintenance Squadron deployed to Zaragoza Air Base, Spain for a four-month weapons training detachment deployment nicknamed "Creek Tally". This was the first time wing aircraft deployed to Spain for this type training. In a related operation, the 611th Tactical Control Flight also deployed their Forward Air Control Posts to Zaragoza at the same time. While there, the 611th provided radar and radio coverage for dissimilar air combat training missions between Northrop F-5E Tiger lIs of the 527th Tactical Fighter Training Aggressor Squadron and McDonnell F-4 Phantom IIs. Also, the 611th Tactical Control Flight was airlifted in two Lockheed C-5A Galaxies rather than the Lockheed C-130 Hercules or Lockheed C-141 Starlifters normally used for radar airborne movements.

The major aircraft related event of 1977 involved the arrival of four additional OV-10As from the states on 9 September 1977. Also, the first two wing OV-10As to receive camouflage painting returned to Sembach from Alverca, Portugal, where the work was performed. In 1980, The 601st Tactical Air Support Group gained additional CH-53Cs and OV-10As.

Due to a congressionally-imposed European troop strength ceiling, all 45 wing OV-10A aircraft along with approximately 800 support personnel of both flying squadrons (the 20th and 704th Tactical Air Support Squadrons) and much of the maintenance complex returned to the states during the period 5 June 1984 through 29 August 1984. The 45 OV-1OA aircraft previously assigned to the wing were now assigned to the 27th Tactical Air Support Squadron at George Air Force Base, California, and the wing's two Bronco squadrons (the 20th and 704th TASS) were inactivated on 30 September 1984.

Base support

The 60lst Wing moved to Wiesbaden Air Base on 1 June 1973. Wing headquarters and tactical air control operations and maintenance units at Sembach moved to Wiesbaden as units. Support units moved to Wiesbaden without personnel or equipment and assumed the mission of the 7101st Air Base Wing, which was inactivated upon their arrival. The 7400th Air Base Group assumed their personnel to continue the operation of Sembach. By 1 October 1973, the wing's relocation to Wiesbaden was complete.


On 1 July 1973 the detachments of the 601st Tactical Control Squadron were replaced by numbered flights and squadrons and the 601st Tactical Air Control Center Squadron replaced the wing detachment operating the tactical air control center. The 601st Tactical Air Support Group was activated to command the wing's forward air control squadrons and the 601st Tactical Control Group was reactivated to command its radar units. In October, the 20th Tactical Air Support Squadron was activated and within a few months, the wing's tactical air control party detachments were transferred to the 20th Squadron.

However, all these events were overshadowed by the announcement, on 8 August 1975, of Project Creek Swap, wherein the wing was notified it would again have to pack its bags and move back to Sembach. Thus, in January 1976, after a two year stay at Wiesbaden, the wing began its move back to Sembach AB. The first OV-1OA aircraft from Wiesbaden landed at Sembach on 7 January 1976, and Colonel Fleetwood Pride Jr., the wing commander, landed another the next day to officially mark the wing's return to Sembach. By 31 March 1976, the wing's move back to Sembach was largely completed.

Projects Creek North and Creek Swap in 1976 involved the expansion of the group's mobile network into northern Germany and the establishment of new radar stations. The 609th Tactical Control Squadron, with two assigned flights, was activated the spring of May 1976. On 20 September 1976, a second tactical control group, the 600th Tactical Control Group, was activated under the wing to control northern operations, while its 600th Combat Support Squadron provided base support for the new radar units. The 600th Group expanded the following year when the 606th Tactical Control Squadron and two more flights were activated at Carl Schurz Kaserne near Bremerhaven.

On 1 June 1985, The 65th Air Division was activated at Sembach to serve as the headquarters for the 601st and the newly-activated 66th Electronic Combat Wing. As part of this reorganization, the 66th Wing was assigned host wing responsibilities at Sembach which included support of the many geographically separated units of the 601st Wing. The 601st Combat Support Group was inactivated and its mission, personnel and equipment were transferred to the 66th Combat Support Group. The 601st Tactical Control Group was also inactivated and its subordinate units were assigned directly to the wing.

Saudi Arabia detachment

The War erupted on 22 September 1980. Shortly after, Saudi Arabia requested US assistance to ensure that Saudi Arabian airspace was not violated during the hostilities. Early in October 1980, the 601st Wing was ordered to deploy a survey team to Riyadh to assist in setting up a mobile radar network in Saudi Arabia. Tactical Air Control System elements in the United States dispatched a Forward Air Control Post, an AN/TSQ-91V Control and Reporting Post operations central cell, and a AN/TYC-10 MPC to Saudi Arabia. The radar operation in Saudi Arabia was collectively known as ELF One.

ELF One involved three operating locations set up along the eastern edge of the Arabian peninsula on the coast of the Persian Gulf and in the central city of Riyadh. The Message Processing Center and Boeing E-3 Sentry aircraft operated out of the latter location. The Control and Reporting Post, along with the communications element of the Saudi Arabian Sector Operations Center, was located on Dhahran Air Base, just inland from the eastern coast of Saudi Arabia. The Forward Air Control Post operated out of Al Jubayl, also along the eastern coast of the country. Some 500 personnel were at the three operating locations. The primary mission of this operation was to support the Saudi Arabia through air defense radar surveillance of the Gulf area. The 601st Wing established an ELF One support detachment on 9 October 1980. After 11 April 1981, the detachment was supported by the 602nd Tactical Control Squadron. The detachment in Saudi Arabia was inactivated on 12 February 1986.

In order to meet the Fiscal Year (FY) 1985 and 1986 Department of Defense budget restrictions, the Air Staff directed the reduction of the mobile TACS by two CRPs and four FACPs in two phases. Phase I resulted in the 1 June 1985 inactivation of the 632nd Tactical Control Flight located at Grafenwoehr and the 1 August 1985 inactivation of the 602nd Tactical Control Squadron at Turkheim and the 619th Tactical Control Flight located at Schwelentrup. The second phase of this drawdown resulted in the 1 October 1986 inactivation of the 603rd Tactical Control Squadron at Mehlingen, the 636th Tactical Control Flight and the 62lst Tactical Control Flight at Wanna and Wiesbaden, respectively. The 601st wide range of communications, which had its beginnings in World War II, was heavily tasked in support of operations during Operation Desert Storm and Operation Provide Comfort, starting with the early buildup in the Persian Gulf during August 1990.

601st Air Base Wing

The 601st air control units became an Operations Group in March 1992 that resulted in the formation of the 601st Support Wing. In 1993, more than half the 601st air control assets deployed to Italy in support of Operation Deny Flight, the United Nations-sponsored operations that established a no-fly zone over Bosnia-Herzegovina.

The Operations Group was inactivated in October 1993 and when the wing was redesignated as the 601st Air Base Wing. At the time, the wing was responsible for over 40 geographically separated units in combination with over 200 people deployed to more than a dozen locations worldwide.

In 1995 the Sembach flightline was returned to German control and the 601st Air Base Wing was inactivated.
