UR-530

UR-530/Almaz In the first half of the 1970's, in competition with Glushko's POS orbital station and RLA series of rockets, Chelomei proposed launch of a 30 tonne version of Almaz into sun synchronous orbit using an upgraded UR-530 launch vehicle.

Status: Design 1977. Payload: 36,000 kg (79,000 lb). Gross mass: 1,200,000 kg (2,600,000 lb). Height: 56.00 m (183.00 ft). Diameter: 4.15 m (13.61 ft). Span: 7.50 m (24.60 ft). Apogee: 200 km (120 mi).

The UR-530 was designed to place 36 metric tons into low earth orbit or boost large payloads to geostationary orbit, Mars, and Venus. It was also designed for launch of Chelomei's LKS manned spaceplane (30 metric tons into a 97 degree, 200 km sun synchronous orbit). Using existing components, Chelomei showed he could develop a launch system with the same performance as Energia/Buran, but using already-developed storable propulsion technologies. The UR-100N first stages, like the ICBM, would be sealed, certified units, requiring no on-pad processing. The second stage would be a version of the existing Proton second stage.

LEO Payload: 36,000 kg (79,000 lb) to a 200 km orbit at 51.60 degrees. Payload: 30,000 kg (66,000 lb) to a 200 km 97 deg SSO.
