The rocket system is placed on the back of the platform with 32 128mm launch tubes capable of reaching targets 20,600 metres away. The crew consists of 5 men. In 1994 Serbia developed new version called Oganj C with designation M94. Oganj C(M94) could fire two type of rockets M91(cluster-type warhead). and M77(HE warhead).
