With an expiring stock of Soviet-made, World War 2-era T-34 Medium Tanks on hand as well as a healthy supply of Soviet 122mm D-30 howitzers, the Syrian Army adopted the "T-34/122" as a Self-Propelled Howitzer (SPH) vehicle. The chassis, hull, and running gear of the T-34 remained largely unchanged which preserved much of the vehicle's mobility and performance while the D-30 and its mounting / recoil hardware was installed along the frontal section of the tank. In this way, the weapon faced the rear of the vehicle but maintained a proper center of gravity which made the T-34/122 system a sound gunnery platform conversion. To keep the conversion process simple, the gun station used an open-air design with rear-mounted folding platform. First use of the T-34/122 came in the 1973 Yom Kippur War against Israel.
Drive power for the new vehicle came from a V-2 series 12-cylinder diesel-fueled engine of 493 horsepower. The running gear included five road wheels to a hull side. A typical crew complement numbered seven with the driver protected from the elements due to his position within the forward hull. The howitzer's mounting hardware included the needed elevation and traverse controls for the gunnery crew. The main gun barrel was capped by a multi-slotted muzzle brake to contend with the inherently powerful recoil effects of the 122mm weapon. Resupply of 122mm projectiles came from accompanying ammunition carriers.
