Korean Space and Satellite Startups

StepLab, a Korean space-mechanisms startup led by Korea Aerospace University professor Oh Hyun-ung, announced on September 22, 2026 that it will jointly develop a 16U cubesat optical payload for space domain awareness with the US research institute SRI under the Korea Research Institute for Defense Technology Planning and Advancement's defense innovation global cooperation program. The payload combines StepLab's micro-vibration isolation technology with optical sensors and onboard AI for detecting and tracking objects in orbit. StepLab, whose products include separation rings, the STEP POD cubesat deployer, and deployable SAR mesh antennas, closed an 11 billion won Series A on July 31, 2026.

Microsatellite startup Naraspace Technology signed an agreement with the Korea Research Institute for Defense Technology Planning and Advancement on September 21, 2026 to lead development of an autonomous proximity-operations microsatellite under the Defense Innovation Company proposal program. The satellite will use an onboard camera and artificial intelligence to recognize objects, plan approach paths, and control its own orbit for inspection and rendezvous missions. The program is worth 6.7 billion won in total, 5 billion won from the government and about 1.7 billion won from private sources, and runs 52 months from September 2026 to December 2030.

ADSYSTEM (AD System), a Cheonan-based drone maker founded in May 2019 by former Air Force maintenance warrant officer Kim Jung-ho, closed a 13 billion won (~$9.9 million) Series A round announced September 16, 2026. LB Investment led, with KDB, JB Investment, Smilegate Investment, Mirae Asset Venture Investment, Mirae Asset Capital, Flux Ventures, and Innopolis Partners participating, taking reported cumulative funding to about 18.4 billion won after a 300 million won seed in 2024 and a 3 billion won pre-A round in August 2025. The company builds low-observable vertical-takeoff reconnaissance drones (the 15 kg AD-3000 in service and the 35 kg armed AD-4000 due in 2027) that navigate without GPS using visual-inertial odometry and SLAM, with anti-jam datalinks and evasive terminal flight validated in Agency for Defense Development tests. On July 30, 2026 it signed an 8.7 billion won Army contract for 3,792 AD-ME1 training multicopters, due by December 27, 2026 under the 500,000 drone warriors program. Proceeds go to a larger automated plant in Hwaseong and completion of the AD-4000.

Hanwha Systems and the Telecommunications Technology Association signed a strategic partnership on August 13 to jointly develop an AI-powered 5G tactical communications system designed from the first line of code to NATO's STANAG 5665, the alliance's first formal cellular defense standard, ratified in February 2026. The pairing combines Hanwha's position as the only Korean firm to have fully deployed the national battlefield tactical communications backbone with TTA's standing as a founding member of 3GPP. The project integrates terrestrial 5G with non-terrestrial networks including satellites, using AI to manage traffic across layers, and includes joint development of MOSS — a vehicle-mounted solution combining mobile tactical 5G base stations, transmission equipment, satellite terminals, and command-and-control gear on a single platform. Building to STANAG 5665 is explicitly aimed at NATO-market interoperability.

Hanwha Aerospace and Korea Aerospace Industries (KAI) formalized a comprehensive partnership to advance Korea's defense and aerospace businesses across four pillars: joint development and export promotion of unmanned aircraft, development and joint marketing of aircraft integrating domestically produced engines and radars, joint entry into the global commercial space market, and cultivation of the defense/aerospace industrial ecosystem and regional supply chains. The two companies pledged to jointly discover and nurture SMEs and startups in the Gyeongnam cluster (Changwon, Geoje, Sacheon), providing annual technology support worth 300 billion won through joint R&D organizations. Industry watchers framed the tie-up — backed by Hanwha's roughly 2.5 trillion won investment in KAI shares — as assembling an air-land-sea integrated defense powerhouse aimed at the global export market, with a KF-21 export package seen as an early priority.

Hanwha Group raised its combined stake in Korea Aerospace Industries (KAI) to 9.04%, becoming the second-largest shareholder after the Export-Import Bank of Korea (26.41%). Hanwha Aerospace acquired 3.02 million shares for 499.9 billion won ($332 million) to reach a 6.5% direct stake, while Hanwha Systems holds 1.53% and Hanwha Aerospace USA holds 1.01%. The group plans to continue purchasing shares through year-end with a target exceeding 12%, aiming to create an integrated defense ecosystem spanning aircraft, weapons systems, and space technologies.

Counter-drone startup Nearthlab signed a business cooperation MOU with LIG Defense & Aerospace on June 2, 2026 to jointly develop and market interceptor drone capabilities for the global integrated air defense market. The agreement pairs Nearthlab's AI software and autonomous-flight interceptor drone technology with LIG D&A's integrated air defense system portfolio. Under the framework the two plan to develop large-scale drone hard-kill proximity defense systems, build derivative interceptor drones sized against large drone threats, and expand cooperation across domestic and export markets for large-drone interception. The tie-up connects one of Korea's most prominent defense startups to a top-tier systems integrator and aligns with DAPA's hard-kill interceptor drone R&D push and the military's broader counter-drone programmes.

Internet giant Naver made an equity investment in drone swarm startup UVify, which raised $41.7M (KRW 60B) from CRIT Ventures and NXC (Nexon holding company) — the largest single drone investment in Korean history. UVify holds the global top market share in drone swarm entertainment (Guinness World Record drone shows, K-pop productions) and is expanding into defense applications. Naver's investment supports UVify's pivot into physical AI and autonomous drone technology for defense AX (AI transformation) use cases.
