According to reports, the military authorities of South Korea and the United States have been monitoring the progress of North Korea’s test of rocket launcher since about 2013; North Korea has repeatedly tested the new 300mm vehicle-mounted multiple rocket launcher (MLRS) since that year. On October 10, 2015, the vehicle was displayed for the first time at the military parade marking the 70th anniversary of the founding of the Workers' Party of Korea. In March 2016, North Korea tested this rocket launcher three times. On April 6 of the same year, South Korean Defense Minister Han Min-gu stated that North Korea would deploy the gun before the end of 2016.
It is estimated that the new rocket launcher has a maximum range of 200 kilometers and can attack the headquarters of the Korean Army, Navy and Air Force in the central region of South Korea, as well as the US military base in South Korea in the western region of South Korea. It uses the imported Sinotruk Howo ZZ2257N5857A 6x6 commercial off-road truck chassis, which has been used by North Korea in the mining and construction industries. The vehicle body is equipped with two box-type 4-unit rocket launchers . One launch box can be hoisted at one time instead of loading a single rocket separately, which greatly reduces the loading time. Before launching, the jacks on both sides of the body need to be lowered to secure the body. The front of the vehicle is equipped with armored louvers and bull bars.
This weapon may be imitated from the Soviet BM-30 "Tornado" MLRS, and may also refer to the American Guided Multiple Launch Rocket System (GMLRS). The two fins at the front and rear are similar to the latter. The crew can remotely launch in the cockpit, with single-shot and salvo modes available. I wonder if the guidance system will use the Russian GLONASS . It may be North Korea's longest-range rocket launcher in 2016. The ammunition may include high-explosive fragmentation bombs, high-explosive fragmentation incendiary bombs, oil and gas bombs or anti-armor cluster fragmentation bombs.
