KSLV-I 2002

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.

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.
