Hanau Army Airfield is a former military airfield, located 5.2 km (3.2 mi) north-northeast of Hanau in Hesse, Germany.


Even before the construction of the airfield in 1936, Langendiebach was used for military purposes. During the Roman period (100-260 AD) the fort Lingen cohort and the small fort Langendiebach was built to secure the Upper Germanic Limes border. A total of 500 soldiers were stationed from Dalmatia. Parts of these constructions can still to be found.The construction of the airfield, in the meadows of Langendiebach, goes back to an accident. In the summer of 1936 the Air Force had to hold maneuvers. In an air exercise, machines were involved from the Ju-TYPE 52nd. One of these machines was forced to perform an emergency landing and landed it on the meadows of Langendiebach. After recovery of the machine it was discussed to build an airfield of the high command in the meadows.

Ground was broken for the construction of the Langendiebach Airfield, or Fliegerhorst Langendiebach as it was then known, in the summer of 1936, after a Junkers Ju 52 on maneuvers made an emergency landing in the meadows behind Reusserhof. Although it was originally intended that there should be three phases of construction, only the first phase of construction was completed, due to the outbreak of World War II. The official opening of the Fliegerhorst on 19 March 1939 was marked by a large celebration, involving a parade from the center of Erlensee to the front gate, and a Volksfest of 25,000 German civilians, who were treated to an air show.

In 1940, Langendiebach became the site of a glider school (Flughafen-Bereichs-Kommando 3/XII), the graduates of which went on to participate in, among other operations, the invasion of the Soviet Union ("Operation Barbarossa"). In addition to gliders, there were various experimental aviation units at Langendiebach, including a high-altitude fighter squadron. From the middle of 1944 until the Americans succeeded in crossing the Rhine, two successive groups of Junkers Ju 88 Nightfighters, the I/NJG 4 then III/NJG4, were stationed at Langendiebach. Once the Americans had crossed the Rhine River, these elements of the Nachtjagdgeschwader 4 (NJG 4) were withdrawn to North Eastern Germany.

The three most destructive bombing attacks on Fliegerhorst Langendiebach occurred on 9 September 1944, 10 November 1944 and 24 December 1944. The bombing raid carried out on 10 November involved 229 B-24 Liberators, which dropped a total of 431.5 tons of bombs. This bombing was conducted in the light of recent intelligence, which revealed that the Langendiebach runway had recently been extended by some 300 meters to accommodate three Messerschmitt Me 262 jet fighters of Kampfgeschwader 55 (KG 55) "Greif", however the unit never received any of the jet fighters.

In order to divert allied attacks away from Langendiebach, the Germans emplaced decoy airfields, consisting of wooden mock-ups of aircraft and of airfield facilities, in the vicinity of Mittelbuchen, Kilianstädten, and Roßdorf. These succeeded in leading low-flying aircraft astray on many occasions, but could not prevent the comprehensive destruction inflicted upon Langendiebach by war’s end. The buildings and facilities of the air base were assessed as 20% destroyed, and the severely pockmarked runway as totally unserviceable. Furthermore, the woods were bombed from Bärensee to Rückingen, in order to eliminate the camouflaged aircraft in parking spots concealed by woods. Present-day B40, which could be used as an auxiliary runway, was also bombed.

Fliegerhorst Langendiebach's facilities and airfield were totally unserviceable when the Americans occupied the area in April 1945, and the airfield was converted by IX Engineering Command, Ninth Air Force into an Army Air Forces advanced Landing Ground, designated Y-91. Air Force units used the airfield as a casualty evacuation and combat resupply airfield by the IX Air Service Command. After the German Capitulation on 8 May, it was re-designated as "Army Air Forces Station Hanau/Langendiebach". Army Air Forces units moved out in August, and the facility was taken over by United States Army.

Hanau became a major United States Army aviation facility during the Cold War, also known as Fliegerhorst Army Airfield. In 1952, several construction projects were undertaken to give the airfield back its character as a military facility. It was during this period that the large ammunition bunkers west of the airfield were built. From 1957 to 1960, Hangars 1302, 1303 and 1304, and the control tower were converted and refitted to accommodate helicopter aviation. Due to the troop reductions pursuant to the Conventional Forces in Europe Treaty and the Treaty of Vienna, many battalions have been removed from Fliegerhorst since 1991. Fliegerhorst still stands as one of the most important US Army Aviation Airfields in Europe.

In 1990, the following elements were stationed at Hanau AAF:

  • 2-227 Avn: 18 AH-64A, 13 OH-58C, 3 UH-60A
  • 3-227 Avn: 18 AH-64A, 13 OH-58C, 3 UH-60A
  • 8-158 Avn: 4 UH-1H
  • I-227 Avn: 2 UH-1H
  • TF Viper: 15 UH-60A, 3 EH-60C, 6 OH-58A, 6 OH-58D, 6 UH-1H
  • 3rd Battalion 20th Field Artillery (Formerly 2/75th Field Artillery): 24 M109A3 SP Howitzers
  • 1st Battalion 32 Field Artillery: 6 Lance Missile SP Launchers, 8 SP Loader/Transporters


The airfield was gradually drawn down following Operations Desert Shield and Desert Storm, and was closed entirely no later than 2007. All US Army assets in the Hanau Military Community were officially returned to the local government in 2008, and the MilCom was deactivated.

Fire Incident June 30th, 2015
