K136 Kooryong

   The K136 Kooryong multiple launch rocket system was developed and deployed in 1980s. A total of 150 of these multiple launch rocket systems were built and are currently in service with the South Korean Army.

   The Kooryong fires two types of rockets, a standard K30 and extended range K33. The standard rocket is 2.4 m long and weights 54 kg. The K33 is 2.53 m long and weights 64 kg. The K30 has a maximum range of 23 km. Improved K33 has a range of 36 km. There are two types of warheads - conventional HE and pre-fragmented HE, containing 16 000 steel balls.

   The K136 Kooryong fires single round, partial or full salvo. Firings are undertaken from the driver's seat or remotely from the vehicle.

   This multiple launch rocket system is mounted on KM809A1 6x6 truck chassis. It is powered by a diesel engine, developing 236 horsepower. Vehicle has a full-time all wheel drive and is fitted with a central tyre pressure system.

   This MLRS is reloaded manually in about 10 minutes.  Reloading usually takes place away from the launch position to avoid counter battery fire. Reload rockets are carried by escorting KM813A1 6x6 resupply truck, which carries 72 rockets.

   A fire control center is based on a 4x4 chassis. It is used for enhanced fire accuracy.
