Burya flight 7 - . Nation: Russia. Apogee: 15 km (9 mi). Cruise stage tanks 1 and 4 empty. The flight lasted only to T+96 seconds. At this point, duirng fseparation of the boost and cruise stages the vehicle became unstable and was unable to achieve level powered cruise flight..

1958 September 10 - . Launch Site: Kapustin Yar. Launch Complex: Kapustin Yar VLAD. Launch Vehicle: Burya La-350.

Burya flight 8 - . Nation: Russia. Apogee: 15 km (9 mi).
Cruise stage tanks 1 and 4 empty. The boosters operated normally and the cruise stage ignited at Mach 2.95-3.0. At T+95 seconds there were problems at separation of the boosters, leading to cruise stage instability and an asymmetric airflow through the ramjet diffuser leading. This caused significant variations in thrust. The pressure in tank 3 dropped at T+160s econds and the ramjet flamed out.

1958 December 28 - . Launch Site: Kapustin Yar. Launch Complex: Kapustin Yar VLAD. Launch Vehicle: Burya La-350. FAILURE: Vehicle broke up due to an explosion in the empty propellant tank..

Burya flight 9 - . Nation: Russia. Apogee: 15 km (9 mi).
Cruise stage tanks 1 and 4 empty. The flight continued to T+309 seconds, the longest to date, at which point the vehicle broke up due to an explosion in the empty propellant tank. The boosters operated normally but separation took place normally at Mach 3.3-3.4 (higher than expected).

1959 February 20 - . Launch Site: Kapustin Yar. Launch Complex: Kapustin Yar VLAD. Launch Pad: Burya. Launch Vehicle: Burya La-350.

1959 October 2 - . Launch Site: Kapustin Yar. Launch Complex: Kapustin Yar VLAD. Launch Vehicle: Burya La-350.

Burya flight 12 - . Nation: Russia. Apogee: 17 km (10 mi).
First flight with propellant in tank 4 of the cruise stage. Boosters featured an improved main engines without OT-155 valve (S2.1150 replacing S2.1100). The cruise stage used the improved RD-012U ramjet in place of the previous RD-012. The first stage operated faultlessly and separation was normal without vibrations. Ignition of the cruise stage occurred at Mach 2.87 at 16.8 km altitude. The SVD Air Sensor System worked abnormally, so the decision was made to disconnect the SVD sensors and fly the mission using only the astronavigation system and hold inertial velocity to Mach 3.15-3.2. The flight continued to T+10 minutes 17 seconds and the planned flight program was completed.
