First South Korean sounding rocket, an unguided single solid propellant stage vehicle. Development began in 1990 and the rocket was flown two times in 1993.

Development began in 1990, which was the first domestic single-stage unguided solid-propellant scientific rocket with a length of 6.7m, a diameter of 0.42m and lift-off weight of 1.2tons. KSR-I was launched on June 4 and September 1, 1993, respectively carrying an ultraviolet radiometer with the mission to measure the vertical ozone distribution in the stratosphere over the Korean peninsular. Temperature, acceleration and the other parameters were also measured to examine the performance of the rocket throughout the test flights. KSR-I had the payload capacity of 150kg and could reach the altitude of 75km.
