History

Design was based on details from the M101 and leFH 18, with many technical improvements to increase its capacity and range. First prototype was designated as SH-1 and designed by Military Technical Institute Belgrade in 1951 and produced by then Crvena Zastava Kragujevac today Zastava Arms Kragujevac . Second prototype was developed by Military Technical Institute Belgrade in 1955 designated as SH-2 and he was basis for serial M-56. Serial production started in 1956 Bratstvo Novi Travnik because prior that in 1945 decision was made by communist government of Socialist Federal Republic of Yugoslavia to move factories from Serbia to other parts of newly formed Yugoslavia to help them to develop industries. Because of that decision in 1951 Zastava Arms factory then called Crvena Zastava was partial dissemble and among other parts of Crvena Zastava factory complete artillery program (calibers over 20 mm) together with 250 experts was transferred to Bosnia into new Bratstvo Novi Travnik factory from then Socialist Republic of Serbia to Socialist Republic of Bosnia and Herzegovina to help in Bosnia development at cost of Serbia who was in that time was heavy industrialized and had educated technical staff. It was originally manufactured in Yugoslavia in a 28 caliber version that had the capability to reach up to 13 km. Through the years, M56A1 version is developed with new longer 33 caliber barrel made from new better materials designed for a life cycle of at least 18,000 shots of ammunition and with a stronger breechblock and new recoil systems that allow it to fire modern rounds up to 18+ km with better stability thanks to hydro-pneumatic balancer to compensate for the increased weight as it was able to handle higher pressure in the chamber and counterweights in each support legs. Today M-56A1 and Soko M-09 it is in offer by Yugoimport,and M-56 by BNT TMiH in Bosnia.

According to the United Nations, some 1,500 units of the M56, in its various models, have been produced and over 200 were exported between 1998 and 2004.
