South Korea successfully tests domestic hypersonic glide vehicle

South Korea has successfully conducted the first flight test of its domestically developed hypersonic glide vehicle (HGV). The test, carried out by the Agency for Defense Development (ADD), utilized a transporter-erector-launcher (TEL) from a floating platform at a test range in Taean, approximately 130 km south of Seoul.

During the flight, the HGV was carried to an optimal altitude by a booster before separating and gliding at speeds exceeding Mach 5 (over 6,174 km/h). The vehicle demonstrated the ability to perform complex maneuvers, including high-altitude and low-altitude flight with non-traditional ballistic trajectories, while maintaining structural integrity against extreme heat. The test aimed to validate advanced guidance systems, flight-control technologies, and high-temperature-resistant materials.

This technological milestone is viewed as a strategic effort to enhance South Korea's precision strike capabilities and deterrence. The development occurs amid an intensifying arms race on the Korean Peninsula, following previous hypersonic testing by North Korea.
