Ukrainka (also known as Ookrainka and Seryshevo) is one of Russia's largest strategic Long Range Aviation bases in the Russian Far East. Located in Amur Oblast, Russia, 28 km north of Belogorsk, and 8 km north of the town of Seryshevo, it is a major nuclear bomber base, with large tarmacs and nearly 40 revetments.

The base is home to the 79th Heavy Bomber Aviation Regiment and the 182nd Guards Heavy Bomber Aviation Regiment both of the 326th Heavy Bomber Aviation Division.

In 1955, Ukrainka was one of only six Soviet bases capable of handling the Myasishchev M-4 (NATO: Bison) bomber. The Tupolev Tu-22 (NATO: Blinder) operated from the base in the 1960s-1970s, and by the 1980s, its fleet consisted of a large number of Tupolev Tu-95K22 (NATO: Bear-G) and a smaller number of Tu-95K (NATO: Bear-B) aircraft. By 1994, all of the early Tu-95 variants had been replaced by the Tu-95MS (NATO: Bear-H). In 1998, it had 16 Tu-95MS16 and 27 Tu-95MS6 aircraft, according to START I treaty documents[#21].

Units stationed at Ukrainka have included:

73rd Heavy Bomber Aviation Regiment (73 TBAP), with 42 Tu-95 bombers in the mid-1990s, many from Dolon. 40 Gv TBAP (40th Guards Heavy Bomber Aviation Regiment) with Myasishchev 3M bombers starting in 1957, and Tu-95, Tupolev Tu-134, and Antonov An-26 aircraft through the 1980s and 1990s.

Tu-95 bombers that made up the 1023rd and 1226th TBAPs at Dolon in the Kazakh SSR were withdrawn to Ukrainka after the USSR dissolved in 1992.

In 2007, units stationed at the base included:

326th Heavy Bomber Aviation Division (326 TBAD) headquarters, which arrived from Soltsy-2 in the Leningrad Military District in 1998, and was probably disbanded in 2009–2010. . Under control of 37th Air Army from October 1994.
