Nuri (Korean: 누리; lit. 'world'), also known as KSLV-II (Korean Space Launch Vehicle-II), is an expendable, three-stage-to-orbit, small-lift launch vehicle, the second one developed by South Korea and the successor to Naro-1 (KSLV-1). It is developed by Korea Aerospace Research Institute (KARI). All three stages use Korean developed launch vehicle engines, making Nuri the first orbital launch vehicle entirely developed and manufactured in South Korea.
