  • HUSS (Harbor Underwater Surveillance System)

  • Harbor Underwater Surveillance System (HUSS) is a surveillance system - consisting of a sound locator and other sensors - installed at major ports to detect, identify and track hostile targets infiltrating underwater. A submersible passive sonar system is installed in the open sea to enable early detection of enemy submarines, surface ships and semi-submarine boat while a magneto-acoustic detection device is installed in the inland waterways to detect and track surface ships, submarines, transfer ships and other underwater infiltration. In the inner harbor, high-frequency active sonar, radar and electro-optical detection equipment are used to detect and track special operations forces as well as submarines.

  • Submarine-launched Mobile Sea Mine
     
  • Submarine-launched Mobile Sea Mine is a torpedo defense system developed to respond effectively to enemy torpedoes to enhance ship survivability. The system is divided into the two types: one for surface ships and one for submarines. It is expected to be mounted on Ulsan-I class and above battleship and Changpogo-II class submarines. It moves according to the embedded decoy logic, triggers babbled signals to disrupt enemy torpedoes.

  • KSS-Ⅲ Sonar System

  • KSS III Sonar system integrates and processes sound signals picked up by acoustic sensors in order to detect, track, and analyze targets such as surface ships, submarines, torpedo, sea mine, etc.
    Comprised of a total of eight underwater sensors and inboard equipment including passive array sensors the Integrated Signal Processor, the system makes detection of remote targets, torpedo alert and sea mine detection feasible.
