The M-56 Howitzer is a 105mm artillery gun from Serbia. Early towed version is comparable to the German 10.5 cm leFH 18 and the AmericanM101 howitzer while newer M-56A1 and self propelled M-09 Soko has more improvements and greater range.
History
The gun's design is based on the M101 and leFH 18. The gun's initial model was the SH-1, designed by the Military Technical Institute Belgrade, Yugoslavia, in 1951. It was produced by Crvena Zastava in Kragujevac, now Zastava Arms. Second prototype, also developed by Military Technical Institute Belgrade, in 1955 designated as SH-2 was basis for serial M-56. Serial production started in 1956 Bratstvo Novi Travnik because prior to 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 in order to develop their industries. Because of that decision in 1951 Zastava Arms factory, then called Crvena Zastava, was partially dissembled and 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 in that time was heavy industrialized and had educated technical staff. The original production version was 28 caliber with a maximum range of 13 km.
MTI developed the M56A1 version, with a longer 33 caliber barrel designed to last for at least 18,000 shots, with a stronger breechblock, with recoil systems that allow it to fire modern rounds up to 18 km and a hydro-pneumatic balancer. The M-56A1 and M09 Soko Self-propelled artillery are offered by Yugoimport and the M-56 by BNT TMiH in Bosnia.
The M-09 Self propelled 105mm gun has direct and indirect shooting capabilities. It can carry up to 60 rounds. It can be mounted on various truck chassis including TAM, FAP, TATRA, KAMAZ and Mercedes models.
