Bratsk Airport (Russian: Аэропорт Братск) (IATA: BTK, ICAO: UIBB) is an airport in Irkutsk Oblast, Russia located 8 kilometres (5 mi) north of Bratsk. It is a mixed use airfield, providing 32 parking spaces for medium-sized airliners, as well as a large number of branched fighter revetments.
The 350 IAP (350th Interceptor Aviation Regiment) arrived in 1984 with a number of Tupolev Tu-128 (Fiddler) aircraft. Bratsk was responsible for air defense of most of the Siberian interior region and depended on the long-range capability of the Tu-128 to cover this vast territory. By the 1990s the unit had been upgraded with MiG-31 jets. The 350 IAP was disbanded in 2002.
Currently Bratsk continues to serve a vital civil aviation role as a staging base for cargo flights to Kamchatka. Recent Google Imagery showed 7 Ilyushin Il-76 jets parked on the tarmac. The airport is operated by AeroBratsk, its major civilian tenant.
