1 602 nd AIRCRAFT CONTROL AND WARNING SQUADRON LINEAGE STATIONS ASSIGNMENTS COMMANDERS HONORS Service Streamers Campaign Streamers Armed Forces Expeditionary Streamers Decorations EMBLEM EMBLEM SIGNIFICANCE MOTTO NICKNAME OPERATIONS From 1948 until 1955, Birkenfeld Air Base was under the command and control of the 602nd AC & W Squadron. The 602nd AC&W Squadron has its roots in the 602nd Tactical Control Squadron which was redesignated the 602nd AC&W Sq. on 23 November 1948 just before moving to Birkenfeld from Darmstadt. The mission of the 602nd was to provide early warning radar coverage and navigational aid to all aircraft flying over the occupied zones.

2 The main body of troops arrived at Birkenfeld on 8 December This was the first American unit to move into the French Zone and they came to build. From 12 Quonset huts of that first winter came the permanent structures familiar to post-1953 assignees. "Cornbeef" the AC&W site had an AN/CPS-1 search radar, AN/CPS-4 height-finder, several radio relay sites (call sign: 03 Zulu) and Direction Finding sites (call sign: Cornbeef D/F) operational within a 100-mile radius of Birkenfeld. Cornbeef D/F was ultimately designated a Net Control Station (Master DF site) and directed the efforts of 5 other sites in the Northern Europe UHF D/F Net. Eventually by 1954 "Cornbeef Control" a high altitude Air Traffic Control Center was set up and operated on Erbskopf. This non-radar ATC function came about due to the increasing assignment of high performance jet aircraft into Europe. Later renamed Rhein Control it continued to grow until the mid 60's. In the Late 60's the Air Traffic Control functions were taken over by the Germans and relocated to Frankfurt Air Traffic Control Center. Records indicate the 602nd was known for its parties and athletic prowess in baseball, basketball, touch football, tackle football, and other sports. Victories were celebrated either on base or off base. In early 1955, the decision was made to move the 602nd to Giebelstadt, Germany and control of Birkenfeld AB passed to the 619th TACONRON that had recently deployed to Birkenfeld from France. Commanders of Birkenfeld Air Base for 602nd were: Major Eldy E. Crowell (8 Dec Jun 1949); Capt. Gene B. Grove (24 Jun Sep 1949); Maj William E. Hartless (3 Sep Mar 1950); LTC Richard L. Bisgard (13 Mar 1950-Dec 1951); LTC Toy B. Husband (Dec Feb 1955); Maj Dolph G. Franz (24 Feb Jun 1955); Capt William C. Deemer (8 Jun Aug 1955); Capt. William A. O'Hearn (1 Aug Dec 1955). For the first time on July 5th, 1946, organization records refer to the 555th as the 501st Aircraft Control & Warning Battalion. Its companies become the 601st through the 604th respectively. At the same time, minus personnel and equipment, Battalion Headquarters and the 603rd were transferred to Wiesbaden, and then inactivated. The remaining Squadrons (601st, 602nd and 604th) were assigned directly to Headquarters USAFE, and they too were inactivated. By September 25, 1947 the 501st AC&W Battalion was history. In the early months of 1949, a worsening of the Russian and World situation occurred. These changes resulted in the 501st Tactical Control Group, Headquarters and Headquarters Squadron, being reborn on May 18th, 1949 as the 501st Aircraft Control and Warning Group. The newly christened unit was assigned to USAFE 2nd Air Division. On May 25th the 603rd AC&W Sqdn. was activated at Hof, Germany. By June 10th, 1949 also activated were the 601st AC&W Sqdn. at Rothwesten, near Kassel Germany (American Zone), the 602nd AC&W Sqdn. at Birkenfeld, Germany ( French Zone ), and the 604th AC&W Sqdn. at Friesing.

3 On Jul. 15, 1953 the 604th AC&W Sqdn. was transferred to the 155th Tactical Control Group. The 603rd AC&W Sqdn. moved from Hof to Giebelstadt early in 1953, and eventually in the winter moved again to Langerkopf, near Kaiserslautern, Germany. The 807th Tactical Control Sqdn. moved from Landsberg to Kaiserslautern during the summer and fall of 1953; and Group Hdq. was also moved there in September of that year. In 1953 the 3rd Shoran Beacon Flight became a tenant at Rothwesten, receiving logistical support from the 601st AC&W Sqdn. there. As of November 1954, the 501st Tactical Control Grp command line up was Col. Robert C. Sexton heading the Group. Commander of the 601st AC&W Sqdn. was Lt. Col. Daniel C. Wolf. Lt. Col. Toy B. Husband commanded the 602nd AC&W Sqdn., and Major Donald H. Brown commended the 603rd AC&W Sqdn. Commander of the 807th Tactical Control Squadron was Lt. Col. Charles G. Whitley.

4 The Base, and several Tech Site locations, was turned over to advance elements of the 602nd Tac Con Sq (TCS) during the summer and fall of The 602nd TCS was redesignated the 602nd AC&W Sqdn on 23 Nov 1948,just before the unit moved from Darmstadt Military Post, Germany to Birkenfeld/Nahe. When the main body of 602nd troops and equipment arrived from Darmstadt on 8 Dec 1948, construction of temporary quarters (Quonset Huts) was undertaken to house the troops for the winter. At least twelve (12) Quonset huts were initially constructed for quarters or for administrative offices. One of the major problems during the first harsh winter was an everpresent sea of mud that hindered all activity. An aggressive base-building program during the next five years led to the permanent structures and base-layout that was so familiar to post-1953 assignees. 602nd AC & W SQDN ( ) The Squadron mission was to provide early warning radar coverage to the limits of its equipment and to provide navigational aid to all allied aircraft flying over the Occupied Zones of Europe (Call sign: Cornbeef ). In addition to the installation of search (AN/CPS- 1) and Height-Finder (AN/CPS-4) radar on the Tech Site at Erbeskopf (located about 10 miles from the Base), the Squadron also established, manned and operated several Radio Relay Sites (Call sign: 03 Zulu ) and Direction Finding (D/F) Sites (Call sign: Cornbeef D/F ) within a 100 mile radius of Birkenfeld. Combed D/F ultimately was designated a Net Control Station (Master) and directed the fix efforts of 5 other Sites in the Northern Europe UHF D/F Net. Soon a MARS Station was also operational (Call sign DL4HQ) which permitted tele phone calls to be patched back to the States to sweethearts, families, and friends. By 1954, with the assignment of ever more high-performance jet aircraft in Europe, a high altitude Air Traffic Control Center was set up and operated on Erbeskopf (Call sign: Combed Control ) Note: This conventionally operated ATC (non-radar) facility was later renamed Rein Control and continued to grow through the mid-1960s, gaining enrooted radar capability. The plans to provide radar approach-control services for aircraft landing at Ramstein, Sembach, Landstuhl, Hahn, Bitburg and Spangdahlem Air Bases did not come to full realization due to the technical difficulties involved. The Air Traffic control function was finally taken over by the Germans and relocated to Frankfurt Air Traffic Control Center in the late 1960s. In early 1955, the decision was made to move the 602nd to Giebelstadt, Germany, and on 5 Dec 1955, control of Birkenfeld Air Base passed to the 619th TACONRON, which had recently deployed to Birkenfeld from France.

6 Tactical Control Squadron Darmstadt, Germany 31 December, November, 1948 Subordinate to: 501st TCG Redesignated: 23 November 1948, 602nd Aircraft Control and Warning Squadron Notes: 31 December 1945, B Company of the 555th SAW Bn. became the 602nd Tactical Control Squadron Detachment A Activated: 19 March 1948 Note: 25 May 1948, became the 603rd Tactical Control Squadron 5 June 1978 The 602nd TCS was declared operationally ready with respect to its E-3A AWACS interface capability. 2 October 1978 The 602nd TCS moved to Tuerkheim from Nelson Barracks in Neu Ulm for improved radar coverage in Southern Germany. Their new location was a former German Air Force radar site. 1 October 1986 The 615th AC&WS fixed radar site at Boerfink was inactivated. 1 October 1986 The second phase of the TACS drawdown resulted in the inactivation of the 602nd TCS, 621st TCF, and the 636th TCF effective this date. In addition to those changes mentioned above, still others were underfoot regarding a general TACS drawdown in the Central Region. Specifically, 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 619th TCF located at Grafenwoehr and the 1 August 1985 inactivation of the 602nd TCS at Turkheim and the 632nd TCF located at Schwelentrup. The second phase of this drawdown resulted in the 1 October 1986 inactivation of the 603rd TCS at Mehlingen, the 636th TCF and the 621st TCF at Wanna and Wiesbaden, respectively. In another area of the TACS drawdown interest, was the newly designated Operating Location C, 601st TCW. The 601st TCW, OL-C was designated and organized at Sembach AB on 1 February 1986, to provide ongoing communications support to both the ATOC and 601st TCW of which would otherwise end as a result of Phase II of the TAGS drawdown. The OL-C consists of four components; an ATOC support element, a stand-alone MFC, radio relay-elements, and a Combat Logistics Repair Tear. (CLRT). This team, in peacetime, is made up of the Chief of Maintenance and a small maintenance staff function for the OL-C. However, in event of war, these people would be augmented by wing staff personnel and become the CLRT. Another significant event at the start of 1986 involved the end of Elf One commitment at Al Jubayl, Saudi Arabia on 12 February

7 1986. This date marked the end of over five years (activated 9 October 1980) 601st TCW FACP support for Elf One operations at various locations in Saudi Arabia. 1 August 1985 Both the 602nd TCS and the 632nd TCF were inactivated as part of USAFE's effort to meet a congressionally-imposed European troop strength ceiling Roots of the modern day TAGS network go back to the World War II era and the Army's 555th Signal Aircraft Warning Battalion. This "triple nickel" unit, formed in 1942 from a group of specialists who worked at the New England Telephone and Telegraph Company, stormed ashore in Normandy or, D-Day and progressed across Europe gathering six battle streamers. Throughout the war the 555th provided badly needed aircraft control and surveillance services. On 31 December 1945, the four companies of the 555th became the 601st TCS, 602nd TCS, 603rd TCS, and 604th TCS. The 601st TCS, still active under the 601st TCW today, was activated at Simmershausen, Germany. These newly formed units were assigned to the 501st Tactical Control Group and, from these fundamental and rudimentary beginnings, the TAGS system has become what is today. The base was turned over to advance elements of the 602 nd TCS during the summer and fall of The 602 nd was redesignated 602 ACWS on 23 Nov 1948 just before the unit from Darmstadt, Germany to Birkenfeld. When the main body of 602 nd troops and equipment arrived from Darmstadt on 8 Dec 1948, construction of temporary quarters (Quonset huts) was undertaken to house the troops for the winter. At least 12 quonset huts were initially constructed for quarters or for administrative offices. One of the major problems during the first harsh winter was an ever present sea of mud that hindered all activity. An aggressive base building program during the next five years led to the permanent structures and base layout that was so familiar to post 1953 assignees. Several of the preexisting structures were razed once the base construction program was underway. Ten of the Quonset huts, first used as dormitories during the winter of 1928 then later as warehouses hobby shops recreation buildings survived for the next 20 years (until 1968) when they were finally torn down and replaced by roomier pre-fab structures call Butler buildings. The 602 nd was the first American unit to move into the French Zone and because they came to build, were soon welcomed with open arms by the townspeople and Birkenfeld has remained an Air Force town since that time. Like all Germany, Birkenfeld and surrounding areas still faced a war torn economy and were desperate for work. They had more than enough of the imperious demands of the French military authorities by the time the Americans arrived in The cutting and shipment to France of millions of board feet of Germany s timber without compensation and under the French Army guise of military reparations is still spoken of today in the Birkenfeld area and throughout Rheinland-Pfalz. During this time, young Germans volunteered to help replant entire forests that had been clear cut and shipped to France and today they proudly point to the lush green forests on the hills surrounding Birkenfeld that help replant as youths. The Americans hired the local Germans paid them well and also paid local shopkeepers and businesses for what was needed to build Birkenfeld Air Station. Of course the US troops were viewed at intruders by almost all members of the French Army, primarily because American PFCs earned more pay in a week than most French NCO earned all month and

8 the Americans who were paid in military payment certificates supplemented their military income by bartering their cigarettes and other commissary and BX items with the Germans. In addition to the installation of search (AN/CPS-1) and height finder (AN/CPS-4) radar on the tech site at Erbeskopf (located about 10 miles from the base) the squadron also established manned and operated several Radio Relay Sites (Call sign 03 Zulu) and direction finding sites (call sign cornbeef D/F) within a 100 mile radius of Birkenfeld. Cornbeef D/F ultimately was designated a net control station (master) and directed the fix efforts of 5 other sites in the Northern Europe UHF D/F net. Soon a MARS station was also operational (call sign DL4HQ) which permitted telephone calls to be patched back to the states to sweethearts, families, and friends.
