Main functions of the weapon system, such as navigation, gun lying, loading of ammunition and deployment, are fully automatic.

After that MTI begun work on further improvements of the system, which included installation of the automatic loader, inertial navigation system, automatic transition from the transport position to firing position...[4] The second prototype of SORA was completed in 2013, and it was the first time publicly presented at Partner 2013 arms fair.

[4] In the process of preparation for serial production (in 1975/1976), MTI carried out modifications of the basic Soviet model D-30 into model D-30J (aimed at facilitating operations of the crew during transition from traveling to firing position and reducing the effects of powder gases’ overpressure upon the crew), as well as by developing new HE projectile 122 mm M76 with the range of 17.6 km (10.9 mi) (compared to maximum range of 15.3 km (9.5 mi) of Russian round type OF482).

Later, during the early 1980s, complete technology transfer of D-30J howitzer with associated sighting devices was made to Iraq (Project KOL-7), including design of entire infrastructure and introduction in production, rated for annual capacity of 200 units.

This vehicle has an 8-cylinder, 4-stroke, water cooled MERCEDES OM 402 diesel engine with direct injection, installed longitudinally under the cab.

In the second case, the ballistic computer receives firing data from the command spot and sends back the condition and position of the howitzer.

It has been designed to fulfill requirements of the modern battlefield, which means that shoot-and-scoot principle is adopted as the main mode of operation.
