Full specifications

Performance

Speed, range, altitude and engagement capability.

Performance specifications
Max speed Maximum level speed. For aircraft this is at optimal altitude; for ground vehicles, top road speed. Higher means faster response and better kinematic performance.	70 km/h Stronger than 55% of artillery systems
Range Maximum distance: ferry range for aircraft, operational range for vehicles, maximum engagement distance for missiles. Higher means more standoff or persistence.	500 km Stronger than 53% of artillery systems
Rate of fire Rounds per minute (cyclic). Higher increases suppression and hit probability.	8 rpm Stronger than 70% of artillery systems

Firepower

Armament, payload and guidance.

Firepower specifications
Main armament Primary weapon: main gun, cannon or missile type.	120 mm smoothbore breech-loaded mortar
Caliber Bore diameter of the main gun or rifle. Larger throws heavier projectiles; not simply better, ammunition commonality matters.	120 mm
Max firing range Maximum range of the main gun or rocket artillery (with assisted/extended-range munitions where noted). Higher extends reach.	12 km Bottom 9% of artillery systems

Physical

Dimensions, weight and crew.

Physical specifications
Combat weight Fully loaded weight. Lighter eases transport and bridging limits; heavier often means more armor.	27,000 kg
Crew Personnel required to operate. Fewer reduces exposure; autoloaders trade a loader for mechanical complexity.	4

Propulsion

Engine, power and fuel.

Propulsion specifications
Propulsion type Turbofan, turboshaft, diesel, gas turbine, solid-fuel rocket, ramjet…	Tracked, diesel

Program

Cost, production scale and operators.

Program specifications
Units built Total production run. Higher means proven manufacturing, mature logistics and spares availability.	70 Bottom 8% of artillery systems
Operator countries Number of countries operating the system. More operators means broader support ecosystem.	2 Stronger than 36% of artillery systems
