Nuri (Korean: 누리; Korean pronunciation: [nuriː], meaning 'world' in native Korean), also known as KSLV-II (Korean Space Launch Vehicle-II), is a three-stage 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 indigenously developed launch vehicle engines, making Nuri the first indigenously developed South Korean orbital launch vehicle (the Naro-1 launch vehicle used a Russian-made first stage).
