South Korean orbital launch vehicle. In 2002 South Korea announced it was planning to develop a small satellite launch vehicle by 2005, based on technology flown on the KSR-III test vehicle. By 2005 this was replaced by a completely different design, based on the Russian Angara space booster.

AKA: Korea Space Launch Vehicle-I. Status: In development. Payload: 100 kg (220 lb). Thrust: 244.00 kN (54,853 lbf). Gross mass: 20,000 kg (44,000 lb). Height: 30.00 m (98.00 ft). Diameter: 3.90 m (12.70 ft). Apogee: 300 km (180 mi).

Originally it was planned that the KARI Space Launch Vehicle would be entirely indigenous, building on the systems developed for the KSR-III liquid-propellant sounding rocket launched on November 28, 2002. A drawing of this vehicle showed it to be based on the 12.5-metric ton thrust liquid oxygen/kerosene rocket flown on the KSR-III Two KSR-III stages would flank the core, forming the first stage. The second stage would be the first stage of the core, consisting of a single KSR-III. A solid propellant motor, perhaps based on that flown on the KSR-I and KSR-II, would provide the third stage.

LEO Payload: 100 kg (220 lb) to a 300 km orbit at 38.00 degrees.
