Bagay-Baranovka (also given as Sennoy, 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 and home to the 395th Independent Test Aviation Squadron of the 929th State Flight Test Centre named for V. P. Chkalov.

Units on the base include the 343rd Instructor Fighter Aviation Regiment (343 IIAP), equipped with Sukhoi Su-17 aircraft in 1989-91 and Mikoyan-Gurevich 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.
