This is a self-propelled artillery line researched and manufactured by the Military Technical Academy, by putting the 130mm M46 gun on the KrAZ-255B off-road truck chassis, helping to increase mobility and adapt to modern warfare. Thereby, continuing the success of the self-propelled ground artillery programs previously implemented by Vietnam.

Unlike the self-propelling of light artillery (such as 85mm or 105mm), this task is much more complicated for the M46 gun, because it is a long-barreled gun, large in size and weight, and has a large recoil when fired. Therefore, a suitable chassis such as the KrAZ-255B truck is needed.

The system was researched and manufactured by the Military Technical Academy.

According to published specifications, the system has a crew of 6 gunners, a total weight of 23,300kg, dimensions in marching position of 10,650x2,060x3,540mm, dimensions in combat position of 11,755x3,200x7,450mm, and the time to switch from marching to combat position and vice versa is under 4 minutes.

The M46 cannon has a maximum range of 27,150m; rate of fire of 5-8 rounds/minute; angle range from -25 to 25 degrees; angle range from 0 to 45 degrees.

The gun can fire high explosive fragmentation shells, smoke shells, and tracer shells. In addition, the gun's range can be improved with extended-range shells. The system has a ammunition storage compartment to ensure long-term independent combat capability.

The KrAZ-255B truck chassis is equipped with a YaMZ-238 turbocharged diesel engine with a capacity of 240 horsepower and a 5-speed manual transmission, helping the PTH130-K255B self-propelled artillery system move at a speed of about 70km/h, with the ability to climb a maximum slope of 29 degrees.
