South Korea's Defense Acquisition Program Administration (DAPA) announced on 25 May that it has improved the accuracy of a homegrown ship-launched anti-submarine missile and is on track towards restarting its mass production.
The Korean Anti-Submarine Rocket (K-ASROC), or Hongsangeo as it is locally known, is a vertically launched two-stage missile that carries a 280 kg torpedo as its payload.
The torpedo is ejected from the carrier missile as it nears a targeted submarine and descends via parachute into the water. The torpedo is then guided to its objective via a sonar system. The missile is powered by a solid-propellant motor, has a maximum range of 20 km, and is guided by an inertial navigation system (INS) and GPS.
