152 Mm Mortar M1931 (NM) - Self-propelled Mounts

Self-propelled Mounts

The NM was experimentally mounted on T-26 tank chassis. The resulting self-propelled gun, designated SU-5-3, successfully underwent factory trials in 1934 and even took part in a parade at the Red Square. However, in 1935 the project was cancelled, because the T-26 chassis was considered too weak for a 152 mm piece. The fate of the prototype vehicle is unknown. There is an unconfirmed information that it was rebuilt as SU-5-2, armed with 122 mm howitzer M1910/30.
