KSLV-III is a medium orbit geostationarylaunch vehicle currently under development in South Korea, with the goal of its first launch in 2030.
In February 2018, theMinistry of Science and ICT held a National Space Committee meeting and announced the 3rd Basic Plan for the Promotion of Space Development.[1] In the launch vehicle sector, in order to establish a self-powered launch service foundation, a plan was established to foster a launch service ecosystem based onNuri in the first stage from 2021 to 2025, and to secure price competitiveness through a domesticsatellite launch mass production system in the second stage from 2026 to 2030.[1]
On November 29, 2022, the MSIT held a meeting of the National Research and Development Project Evaluation Committee and passed the preliminary feasibility study for theNext-Generation Launch Vehicle Development Project;[2] it was decided to develop the next-generation launch vehicle, KSLV-III, by investing 2.132 trillion won from 2023 to 2032.[3]
In March 2024,Hanwha Aerospace was selected as the preferred bidder for the government-commissionedNext-Generation Launch Vehicle Development Project Launch Vehicle General Production project, passing the technology capability suitability assessment.[4]
In February 2025, the agenda to develop KSLV-III as areusable launch vehicle has passed the National Space Committee.Korea AeroSpace Administration stated that through this, they expect to achieve thelunar exploration mission in 2032 and secure full reusability technology from 2035 to launch more than 20 times a year and secure universal access to space.[5][6]
Compared toNuri, which was developed in June 2021, KSLV-III is more advanced in comprehensive propulsion performance. Nuri's first stage thrust is 300 tons generated by four 75 tons liquid engines, but that of KSLV is 500 tons.[3]
The KSLV-III's payload is over 10 tons, and it can be used to build aspace station or assemble alunar lander. Methane engines, hydrogen engines, launch vehicle reuse research, and solid booster technology are also being handled by the KSLV-III project.[7]
In November 2022, the MSIT announced that "unlikeNaro-1 and Nuri, which were developed under the leadership of theKorea Aerospace Research Institute, we plan to enter into joint design of the KSLV-III with a system integration company."[3]
One of the most important missions is to transport theKorean lunar lander. It can send a 1.8-ton object to the Moon. The launch vehicle is scheduled to be launched three times in total, and the main plan is as follows:[3]
The preliminary model of the lunar lander will not carry any lunar exploration equipment and will only land on the Moon. The final model, scheduled for launch in 2032, is expected to carry various exploration equipment.[3]
