Osovcy Air Base (Bereza)

Osovcy Air Base, officially designated as Asaŭcy, is located 7 km northwest of Byaroza in the Brest Region of Belarus. It is operated by the Air Force and Air Defence Forces of the Republic of Belarus.

The airfield dates to 1915, when it hosted a combat detachment of Ilya Muromets aircraft from the 4th aviation company. During World War I, German forces occupied the site in September 1915 and deployed Albatros D.I aircraft. In 1955, the 927th Fighter Aviation Regiment (IAP) transferred to the base from Austria. The unit operated MiG-15 aircraft upon arrival, re-equipping with MiG-19s in 1956, MiG-21s in 1962, and MiG-29s in 1986. Between June 1983 and July 1984, the regiment deployed from the base to Afghanistan as part of the 34th Mixed Aviation Corps.

From 1963 to 1987, the base supported unmanned reconnaissance operations through the 510th separate division and the 106th separate squadron, which utilized Lavochkin La-17R unmanned aerial vehicles. The 120th IAP was formed at Osovcy in 1969 with MiG-21S aircraft before its 1971 relocation to the Transbaikal Military District. In 1990, aircraft and personnel from the 5th Guards Fighter Aviation Regiment were withdrawn to the base from Hungary for disbandment.

Following the establishment of the Armed Forces of Belarus in 1992, the resident unit was reorganized as the 927th Fighter Aviation Base in 1993. On August 24, 2010, the facility was transformed into the 927th Center for the Preparation and Use of Unmanned Aerial Systems.

The base hosts the 927th Center for the Preparation and Use of Unmanned Aerial Systems. Current equipment includes Irkut-3 and Irkut-10 unmanned aerial systems. The facility has historically hosted various Mikoyan-Gurevich fighter aircraft, including MiG-15, MiG-19, MiG-21, and MiG-29 variants.
