AKA: Korea Space Launch Vehicle-I;KSLV-I. Status: Active. First Launch: 2009-08-25. Last Launch: 2013-01-30. Number: 3 . Payload: 100 kg (220 lb). Thrust: 1,910.00 kN (429,380 lbf). Gross mass: 140,000 kg (300,000 lb). Height: 30.00 m (98.00 ft). Diameter: 3.90 m (12.70 ft). Apogee: 300 km (180 mi).

It had been decided to develop a first stage in collaboration with Russia, based on the still-in-development Angara launcher. This would be an order-of-magnitude larger than the original KSLV-I design. The first test of this vehicle, still designated KSLV-I, was moved to 2007 and would consist of a launch of the first stage with a South Korean solid rocket motor kick stage to place the small 100-kg satellite into orbit.

KARI oversaw basic system design, system management of the launch vehicle, and basic design of the ground equipment. International cooperation plans called for joint development of the launch vehicle and interface design for the 100 kg Science Satellite 2.

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