Nusantara Poly-Urethane 70

The Indonesian designed and built NDL-40 Ground to Ground Multi Launcher 2.75", Rocket System has been designed and is in the process of testing. This devices used as FFAR 2.75" Multi-Launch Rocket System. The FFAR 2.75 " rocket system is a ground-to-ground weapon system designed to support infantry units in the field. Each system is comprised of 4 modules, each containing 5 rockets (a total of 20 rockets in a system). The modules may be used independently of each other or in any combination with any other module.

This provides many useful configurations for the support of field infantry units. The NDL-40 system operator is approximately 15 meters away from the actual launchers and may adjust the fire control system to variety of different settings. The firing time (0.1 to 9.9 seconds interval) as well as the mode of launch (single, ripple or salvo firing) may be determined by the field operator.

FFAR 2.75" (70 mm or 2.75") rockets motors are manufactured by the flow forming process. The first batch underwater dynamic testing was successfully done in June 1985. This was the last test required in work frame of certification testing. This dynamic test was a success and since then the flowformed tubes were used in production of the FFAR. By using the rocket launcher [also called LAU 97] that has 40 launching tubes and enables "single" or "ripple" firing, the rocket can be fired within 6 seconds each. The impact pattern for such firing is 200 m x 300 m. The rocket launcher it self can go through a 360° azimuth position and has a maximum elevation of 50°. Its unladen weight is 365 kg.; with 40 rockets fitted with the FZ-71 warhead, it weights 935 kg. For firing the rockets one must reckon upon an interval of 150 msec with a "ripple" firing. Its high mobility and firing power make it a highly effective weapon. By using the MK-40 motor, its range is about 6,000 m. and when used with FZ-68 motor its range is about 8,000 m.

NPU-70 (Nusantara Poly-Urethane 70) is developed by IPTN at the stage of technological integration, while prior to this, during the stage of licensing, the factory manufactured FFAR 2.75" and SUT. Rockets with a surface-to-surface launching system and/or 70 mm caliber, NPU-70, will be produced by IPTN are already on a stage of research qualification and installed component development testing. The serial production was scheduled to take place in 1994/1995.
