Russian orbital launch vehicle. From 1996-2001 RSC Energia carried out design studies on the Kvant-1 light launch vehicle with a low earth orbit payload capability of 1.8 to 3.0 metric tons. Market surveys seemed to indicate a need for a new launch vehicle of this class but development funding was not forthcoming.

Status: Design 1994. Payload: 1,800 kg (3,900 lb). Thrust: 1,000.00 kN (224,800 lbf). Gross mass: 83,000 kg (182,000 lb). Height: 29.00 m (95.00 ft). Diameter: 2.60 m (8.50 ft). Apogee: 200 km (120 mi).

The resulting two-stage launch vehicle used Liquid Oxygen/Kerosene propellants. Stage 1 used Soyuz core tooling and was equipped with a single RD-120 engine (from the Zenit-2 second stage) modified for sea level ignition together with a four chamber RD-0124-14D23 engine adapted from the Soyuz second stage. The second stage was the Molniya LM upper stage with an 11D58 engine. The flight control system was based on that of the Yamal spacecraft. The booster could use existing Zenit or Soyuz launch pads, or a railroad Mobile Launch Platform.

The selected design for the Kvant-1 had a launch mass of 83 metric tons and could deliver the following payloads to a 200 km reference orbit: from Plesetsk, 1.75 metric tons; Baikonur, 1.8 metric tons; or from an equatorial Sea Launch platform, 1.95 metric tons. Payload capability could be increased as needed by use of existing solid-propellant booster motors.

LEO Payload: 1,800 kg (3,900 lb) to a 200 km orbit at 51.60 degrees.
