South Korean sounding rocket. Test bed for development of an orbital launch vehicle, powered by the liquid oxygen/kerosene engine planned for the KSLV-I. However flown only once in 2002.
The go-ahead for KARI to proceed with developement of a liquid propellant launch vehicle came in December 1997. The KSR-III demonstrated key technologies for the KSLV-I satellite launch vehicle in the propulsion, guidance, control, and mission design areas.
The Korea-developed pressure-fed liquid oxygen/kerosene motor provided a thrust of 12,500 kgf at sea level. This would be equivalent to the X-405 motor developed in the United States for the Vanguard space launcher in the 1950's. For the test launch, available pressurant only allowed a burn time of 53 seconds, with about 2500 kg of propellant consumed. Available tank volume indicated the stage was designed to be loaded with over 4000 kg of propellant.
Payload: 150 kg (330 lb) to a 80 km altitude.

Korea South South Korea became familiar with large-scale rocketry through maintenance and modification activities on American-supplied Honest John and Nike Hercules tactical missiles. By the 1990's Korea had developed an independent capability to manufacture solid propellant rocket motors of up to one tonne mass. In 1990 KARI was funded to build the first indigenous sounding rockets, flown as the KSR-I and KSR-II. In December 1997 KARI was allowed to proceed with development of liquid oxygen/kerosene rocket motor for an orbital launcher, but this was abandoned when the South Korean government decided it wanted to be among the top ten spacefaring nations by 2015. The existing program was too limited in growth potential to allow that. Therefore it was decided to leapfrog the technology by contracting with Russian companies. First launch of the KSLV-I launch vehicle from the new space centre took place in 2010. More...
KSR South Korean indigenous sounding and test rocket family, using solid rocket motors and a test vehicle with a liquid oxygen/kerosene motor. Further development of the latter into the KSLV satellite launch vehicle was abandoned in 2005 in favor of licensed Russian technology. More...

Nation: Korea South. Agency: KARI. Apogee: 43 km (26 mi). The rocket reached 42 km altitude and a speed of 902 meters per second. It impacted in the West Sea 85 km from the coastal launch site, 231 seconds after launch. In preparation for the launch, KARI and related agencies successfully carried out ignition tests in May and August.
