Sennoy (also given as Bagay Baranovka, Sennoe, or Sennoye) is an air base in Saratov Oblast, Russia located 2 km south of Sennoy. It is a small training base, with training airspace about 5–10 km to the east.
Units on the base include 343 IIAP (343rd Instructor Interceptor Aviation Regiment), equipped with Su-17 aircraft in 1989-91 and MiG-23 and MiG-29E in the early 1990s. The unit has been reported to have disbanded in 1998. However, another report says it had as many as 54 MiG-29s by 2003.
The base also played host briefly to the 176th Fighter Aviation Regiment, flying MiG-29s, when it returned from Mikha Tskhakaya (Senaki), Georgia in 1992; it was quickly disbanded.
