Hanwha Systems Unveils Ultra-High-Resolution SAR Satellite Mockup for the First Time

ADEX Showcase:
Aiming for 15cm-Class Resolution

Hanwha Systems unveiled a mockup of its ultra-high-resolution (UHR) synthetic aperture radar (SAR) satellite for very low Earth orbit (VLEO) in the space sector for the first time in Korea at the Seoul International Aerospace & Defense Exhibition (ADEX) 2025.

On October 20, Hanwha Systems announced that following the launch of its 1-meter-class SAR satellite in 2023, it is currently developing 0.5-meter and 0.25-meter-class models, with the goal of achieving 15-centimeter resolution at altitudes below 400 kilometers. The company also presented a near real-time analysis and dissemination system based on artificial intelligence (AI) interpretation. The Jeju Space Center, which is scheduled for completion within this year, aims to become a domestic hub for satellite mass production, with capabilities for simultaneous production and environmental testing of up to eight small SAR satellites.

In the avionics sector, Hanwha Systems introduced the AESA (GRIFO-EK) under joint development with Leonardo for light combat aircraft, as well as a multi-mission surveillance (MMS) AESA radar targeting integration with the GA-ASI Gray Eagle STOL. In the air defense domain, the company highlighted its AI-based integrated air defense system and short-, medium-, and long-range multi-function radars (MFR). The Cheongung-II MFR showcased export achievements to the UAE and Saudi Arabia, while the long-range MFR for L-SAM emphasized enhanced ballistic missile response capabilities. The LAMD radar for long-range artillery interception was presented for its ability to simultaneously counter multiple threats.

In the counter-drone sector, Hanwha Systems showcased the results of this year’s deployment of its fixed "Critical Area Integrated Counter-Drone System" and the pilot operation of its mobile "Multi-Layered Composite Protection System." The system integrates radar, EO/IR, jammers, lasers, and capture drones to neutralize threats in stages within a 3-kilometer radius. In its laser weapon lineup, Hanwha Systems introduced the world’s first operationally deployed "Cheongwang Block-I" and the development status of the mobile "Block-II." The company also revealed laser cannons for combat vehicles and laser explosive ordnance disposal equipment. The strengths of laser interception include reduced cost per shot and extended operational endurance.

In the maritime sector, Hanwha Systems presented its AI-based "Smart Battleship." By integrating the combat management system (CMS), engine control system (ECS), and integrated bridge system (IBS), the company aims to reduce crew numbers and support unmanned-manned hybrid operations, while enhancing survivability through stealth design. For tactical communications (C4I), Hanwha Systems unveiled the "Integrated Communication Platform," which modularizes tactical 5G, LEO/GEO, and edge cloud technologies into a unified vehicle-based platform.
