Full specifications
Performance
Speed, range, altitude and engagement capability.
| 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. | 62 km/h |
|---|---|
| Range Maximum distance: ferry range for aircraft, operational range for vehicles, maximum engagement distance for missiles. Higher means more standoff or persistence. | 500 km |
| Rate of fire Rounds per minute (cyclic). Higher increases suppression and hit probability. | 1 rpm |
Firepower
Armament, payload and guidance.
| Main armament Primary weapon: main gun, cannon or missile type. | 240 mm M-240 breech-loaded mortar |
|---|---|
| Caliber Bore diameter of the main gun or rifle. Larger throws heavier projectiles; not simply better, ammunition commonality matters. | 240 mm |
| Ammunition Rounds carried (main gun) or standard magazine capacity. | 40 |
| Max firing range Maximum range of the main gun or rocket artillery (with assisted/extended-range munitions where noted). Higher extends reach. | 19.7 km |
Physical
Dimensions, weight and crew.
| Combat weight Fully loaded weight. Lighter eases transport and bridging limits; heavier often means more armor. | 27,500 kg |
|---|---|
| Crew Personnel required to operate. Fewer reduces exposure; autoloaders trade a loader for mechanical complexity. | 5 |
Propulsion
Engine, power and fuel.
| Engine Powerplant model and type. | V-59 diesel |
|---|---|
| Engine power Engine output power. Higher moves more weight faster. | 520 hp |
| Propulsion type Turbofan, turboshaft, diesel, gas turbine, solid-fuel rocket, ramjet… | Diesel |
Program
Cost, production scale and operators.
| Units built Total production run. Higher means proven manufacturing, mature logistics and spares availability. | 588 |
|---|---|
| Operator countries Number of countries operating the system. More operators means broader support ecosystem. | 6 |
