Professor Obrad Vučurović, mechanical engineer and Chief Operating Officer of the Military Technical Institute's Artillery Department, was responsible for overseeing its development and production.

The rocket system is placed on the back of the platform and contains 32 128mm launch tubes capable of reaching targets 20.6 kilometres (12.8 mi) away.

As part of the modernization program, a new 128mm rocket with a range of 50 kilometres (31 mi) and improved circular error probable (CEP) will be produced by Krušik.

Further development of the M-77 concept and the LRSVM Morava led to the creation of the new modular rocket launcher M-18 Oganj, which contains an armored cabin on a 6x6 chassis for up-close battlefield action.
