South Korean launch vehicle, originally scheduled for first flight by 2010. Evidently it would have consisted of a Russian Angara first stage and a South Korean liquid-propellant second stage. In August 2006 it was reported in the Korean press that this launcher configuration was cancelled.

AKA: Korea Space Launch Vehicle-II. Status: In development. First Launch: 2018-11-28. Last Launch: 2018-11-28. Number: 1 . Payload: 1,000 kg (2,200 lb). Thrust: 1,910.00 kN (429,380 lbf). Gross mass: 144,000 kg (317,000 lb). Height: 35.00 m (114.00 ft). Diameter: 3.90 m (12.70 ft). Apogee: 300 km (180 mi).

The second stage would logically be a repackaged version of the liquid oxygen/kerosene stage tested on the KSR-III in 2002 and originally intended to power the completely-indigenous original version of the KSR-I launch vehicle.

LEO Payload: 1,000 kg (2,200 lb) to a 300 km orbit at 38.00 degrees.
