Vozdushny

Russian aerospace corporation Vozdushny Start (Air Launch) in 2000 began designing a system for launching satellites and other payloads into orbit using boosters fired from a transport plane in flight.

Vozdushny Start launch system includes the Ruslan An-124 heavy transport carrying the Polyot rocket. Once Ruslan reaches the required height and speed, it drops the rocket, whose engines ignite roughly five second later. The system might be capable to launch payloads of up to 3.6 tonnes to altitudes as high as 10,000 kilometres.

Vozdushy Air-launch Polyot rocket might use a Kosberg Rocket engine.
