Batken Airport

List of airports by ICAO code: U

The prefix 'U' is used for Russia and all the former Soviet republics except Moldova (LU), Estonia (EE), Latvia (EV) and Lithuania (EY). Each former Soviet republic or group of them is assigned a 2-character (Ux) prefix and Russia has 10 prefixes. The only exception is the prefix UM, which, while used for Belarus airports, is also used for few aerodromes in Russia's Kaliningrad Oblast exclave, including Khrabrovo airport (UMKK). For this reason, there is a UM second-level section under Russia as well as the first level section UM – Belarus.
