An improved version of Indonesia's indigenously developed R-HAN 122 mm rocket has been successfully launched during live firing trials at the country's National Institute of Aeronautics and Space (LAPAN) test facility in Garut, West Java in August 2015.
The latest trial validated improvements in flight stability and range that were incorporated into the R-HAN 122B rocket after an earlier test in June.
The rocket is being developed by a consortium that includes state-owned aerospace and defence equipment developers PT Dahana, PT Dirgantara and PT Pindad, as well as LAPAN, and Indonesia's Ministry for Research, and the Technology and Agency for the Assessment and Application of Technology.
According to PT Dirgantara, the R-HAN 122B has an overall length of 2,810 mm and features a hydroxylammonium nitrate (HAN) rocket motor, which has a burn time of three seconds. Average stated thrust is 1,437 kg, with an impulse of 4,809 kg/s, enabling it to achieve a maximum range of 30.5 km. The rocket carries a 15 kg warhead, although no details were revealed on its type.
The company also stated that the R-HAN 122B is compatible with the Russian and Czech Republic Grad BM-21 and RM-70 multiple launch rocket systems (MLRS), the latter of which is in service with the Indonesian Marine Corps.
