Effective velocity gain compared to vertical launch 1130 m/s. It was concluded that the extensive development would be required for the combination-cycle engines, resulting in an extended development schedule and high technical risk. The more conservative subsonic-launched MAKS was chosen instead. Manufacturer: Molniya. LEO Payload: 21,000 kg (46,000 lb). to: 200 km Orbit. at: 51.00 degrees.
