The Indonesia Ministry of Defense (MoD) announced in late-October that state-owned arms manufacturer PT Pindad has completed the development of a 122 mm multiple launch rocket system (MLRS) known as the R-Han 122B.

In a social media post, the MoD said that PT Pindad conducted a “series of successful trials on the system” before declaring its completion of development.

The MoD added it is now working on finalising the contract for the procurement of R-Han 122B systems and 60 mm mortar ammunition.

Janes earlier reported that PT Pindad has been producing the R-Han 122B for the Indonesian Marine Corps on a low-rate initial production (LRIP) basis since 2017, but the service needs more than 1,000 rounds of the Global Positioning System (GPS) and inertial navigation system (GPS/INS)-guided weapon across its three divisions by 2024.

The R-Han 122B has a calibre of 122 mm, an overall length of 2,810 mm, and is driven by a hydroxylammonium nitrate (HAN) rocket motor, according to PT Pindad.

The weapon has a 3.3 second burn time and can carry payloads weighing up to 15 kg over a maximum range of 305 km at a speed of Mach 1.8.
