MORAK was an upgrade package designed for RM 70/85 Rocket Launcher to enhance its combat efficiency, safety and comfort of crew and enable efficient use of the latest extended range rockets. The upgrade package also provides for use of a national command and fire control system DELSYS. MORAK system was developing in two variants:

  • RM 70/85 M (an upgraded system that maintains the 122 mm system)
  • RM 70 MODULAR (an upgraded modular system that enables to use the original 122 mm ammunition as well as the NATO 227 mm MLRS ammunition)


The upgrade package consists of a navigation and positioning system (NPS), new onboard control system, fire control system (FCS), automatic diagnostics system, radio for automatic or automated data transfer to/from a superior command level and other ancillary equipment. The system operates under WINDOWS NT and enables integration of GPS. The upgrade package enables to decrease the number of the crew from 4 to 3. The launcher is operated from inside the cabin. In addition aiming and firing can be also done from an outside shelter using a remote control block.

The basic upgrade package is identical with the above RM 70/85 M variant. The major difference is in use of 227 mm MLRS system to increase the range and ensure NATO compatibility and future growth-potential of the original RM 70 system. Other parameters remained as on the original launcher.
