Low cost solution of 122mm self-propelled howitzer using AMX-13 light tank tracked chassis 1505158.

It's not the first time, that the Russian D-30 122 mm howitzer is used to create a new mobile tracked or wheeled self-propelled howitzer.

China has developed the SH-2, a D-30 122mm howitzer mounted at the rear on a 6 × 6 cross country light truck chassis. The 122 mm howitzer is mounted on a turntable which is fitted on a flatbed at the rear of the crew compartment. The 122 mm howitzer retained the distinctive multi-baffle muzzle brake and recoil-recuperator mechanism mounted above the gun barrel on the original D-30/Type 86.

The Serbian Defense Company YugoImport has developed the SOKO SP RR 122 mm (Self-Propelled Rapid Response), a truck-mounted gun-howitzer based on integration of 122 mm D-30 J howitzer with 6x6 truck chassis.

The solution of Disenos Casanave is to use the chassis of the light tank AMX-13 as a self-propelled howitzer which is normally fitted with a turret armed with a 105 mm cannon. The idea is to replace the original turret by a D-30 122mm howitzer mounted in the centre of the hull.
