The A407 100mm anti-tank gun M1977 is a Romanian rifled 100-mm anti-tank gun which serves as the main towed anti-tank gun of the Romanian Land Forces from 1975 until present. Versions of the M1977 gun were installed on main battle tanks (TR-77 and TR-85) and ship turrets on river monitors.

History

The A407 100mm anti-tank gun was the first artillery piece designed in Romania after World War II. The first variant of the gun, the M1975 (M stands for Model) had a semi-automatic horizontal sliding wedge type breech lock. The second variant, M1977, had a more practical vertical sliding wedge breech block.^[1]

The M1977 can be also used as a field gun at brigade level, as it has a maximum range of 20.6 kilometers. After 1992, the M1977 anti-tank guns were modernized with improved optical sights.^[2] The gun can be towed with the DAC 665T truck and has a maximum road speed of 60 km/h on road and 30 km/h off-road.

Variants
