As the North Korean Type 75s are being removed from their front line positions, their replacements appear to be truck mounted 22 tube 240mm rocket launchers. This system has been around since 1991, and is called the M1991. The 400 kg (880 pound) 240mm rocket has a range of 30 or 60 kilometers. The 50 kg (110 pound) warhead is lighter in the longer range version. The new, longer range 240mm rocket is in limited production. Both versions of the rocket can be used in the same launcher. The launcher is apparently designed to be fitted on any 6x6 truck that can handle the weight of the rockets (8.8 tons) and the launcher itself (about 5 tons). Any commercial truck used as a dump (or garbage) truck will do. Examples of the M1991 seen in parades appear to be using a Rumanian truck. North Korea cannot produce many of these new 240mm launchers because of cash and materials shortages. Unable to build its own trucks, North Korea has to scrounge together the cash to buy foreign made vehicles.
