South Korea to Deploy Military Reconnaissance Satellites on Home-Built Nuri Rocket
By Drooid · · How we work
Core Launch Plan
South Korea will place four electro-optical (EO) reconnaissance microsatellites into orbit on the Nuri rocket’s 11th mission in 2031, the first time a domestically produced launch vehicle carries military spy satellites. A 12th Nuri launch in 2032 will send three companion satellites to operate with the multipurpose Arirang-8 synthetic-aperture-radar (SAR) satellite. KASA plans at least one Nuri launch each year from 2027 through 2032 to meet public and defense satellite demand.
Background & Context
Current capability rests on Project 425, which fields one EO/IR satellite and four SAR satellites launched by SpaceX. Reliance on U.S. launch services has limited timing and autonomy. The fifth Nuri flight earlier this month delivered five Earth-observation microsatellites, raising the vehicle’s cumulative success rate to 80 % (four of five launches). Officials see domestic launches as a way to shorten revisit cycles over the Korean Peninsula and reduce dependence on foreign launch schedules.

Timeline
- 2027-2028 – Annual Nuri launches begin; additional Earth-observation microsatellites scheduled for late 2027, a next-generation medium-size satellite in 2028.
- 2031 – 11th Nuri launch carries four EO reconnaissance microsatellites.
- 2032 – 12th Nuri launch carries Arirang-8 and three companion satellites.
- 2028 – Low-altitude test flights of a small reusable vehicle.
- 2032 – First-stage vertical-takeoff-landing tests for the next-generation launch vehicle.
- 2035 – Goal to achieve full-stage recovery and reuse capability.
- December 2026 – Decision on a second space center expected.
Data & Statistics
- Four EO microsatellites slated for 2031.
- Three companion satellites planned for 2032.
- Five Earth-observation microsatellites placed on the fifth Nuri flight.
- Launch success rate: 4 of 5 (80 %); target >90 % after the 10th launch.
- Nuri payload capacity: 2.2 t to a 500 km orbit; next-generation vehicle aims for 7 t.
- Annual cadence: at least one mission per year 2027-2032, with two launches projected for 2030.
Why It Matters
The shift to a domestic launch platform shortens the “revisit cycle” for monitoring the Korean Peninsula, enabling more frequent observation of North Korean sites. Linking the new EO microsatellites with Project 425 assets creates an integrated network that supports air and missile-defense systems. Reducing reliance on U.S. launch services also enhances strategic autonomy while preserving alliance complementarity.
Verbatim Quotes
- “We plan to launch four microsatellite system satellites in 2031 and to provide additional cooperation for about eight more.” — Defense Minister Kang Shin-chul
- “Once the small satellites are launched, they are expected to be linked with the reconnaissance satellites secured through the existing Project 425 to build a network,” — Kim Yeol-soo
What's Next
The 12th Nuri mission in 2032 will test multistatic SAR observation with Arirang-8 and its companions. Parallel to the launch schedule, the government will advance a next-generation vehicle capable of 7-ton payloads and reusable first-stage technology, with key test milestones in 2028, 2032 and full reusability by 2035. KARI is transferring 129 of 204 tooling sets to Hanwha Aerospace’s Suncheon plant to accelerate cost-effective assembly and pave the way for commercial launches. A decision on a second launch site is expected by year-end, positioning South Korea for more than ten launches annually once the next-generation vehicle enters service.
