The area was used for military training during Austria-Hungary and during the First Republic of Czechoslovakia. Since 1938 the area was controlled by the Wehrmacht and used for training. In March 1945 the Wehrmacht built a field airport next to village Hradčany. The airport was used by a wing of Messerschmitt Me 262 and later damaged by American bombing. After the war, German speaking inhabitants were expelled. On October 30, 1946, the Czechoslovakian Army closed up the area and established military base, later known as Military District Ralsko. In 1968, during the initial phases of Soviet occupation of Czechoslovakia, Soviet planes shipped military materiel through the airport. The whole base was handed over to the newly established Central Group of Forces of the Soviet Army. To host the Soviet 236th bomber-fighter squadron and part of the 131st air division the airport runway was expanded to 2,800 meters and completely covered with concrete. Over forty hardened hangars hosted about 44 Mig-21 fighters and Mi-24 helicopters. Fuel tanks had capacity over 37,000 m³. Between 1945 and 1968 the Czechoslovak Air Force operated several regiments from Hradčany airfield:
46 Bomber Division between 1951-1955.
24 Bomber Regiment between 1952-1954.
25 Bomber Regiment between 1952-1954.
17 Fighter Regiment between 1955-1964.
26 Fighter Regiment between 1956-1958.
30 Fighter-Bomber Regiment between 1958-1959.
2 Fighter-Bomber Regiment between 1964-1968.
Aircraft operated from the airfield included Arado Ar-96Bs, AS-11s, and MiG-15.
Former airport
After the fall of the communist party from power in 1989, withdrawal of Soviet troops was negotiated in February 1990. The last soldier left the district in May 1991. The district lost its military status in the same year, was open to the public and on January 1, 1992 the village of Ralsko was established by joining of nine villages together. Between 1993 and 2004 the area was extensively cleaned up from chemical contamination and searched for unexploded ammunition. Soon after the airport was handed over to Czech authorities several projects has been proposed: setting up large cargo terminal here, to use it by Rolls-Royce for engine tests or to attract a low-cost carrier. Due to unwillingness and inability of authories none of the plans has materialized. The state was unable even to provide protection of existing structures and these became target of vandals and looters and were completely devastated during the 1990s. The airport is now used by ultralight clubs, for unorganized car races and for rave parties. Newer plans propose to turn the location into a recreational area.
