AHS Krab

A Polish tracked self-propelled howitzer combining a British AS-90-derived turret with a 155 mm/52-caliber gun on a K9 Thunder-derived hull, giving it NATO-standard ammunition compatibility and long range. Large deliveries to Ukraine from 2022 made it one of the most combat-tested Western-pattern howitzers of the war.

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.: 60 km/h

Stronger than 27% 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 52% of artillery systems
Rate of fire Rounds per minute (cyclic). Higher increases suppression and hit probability.: 6 rpm

Stronger than 53% of artillery systems

Firepower

Armament, payload and guidance.

Main armament Primary weapon: main gun, cannon or missile type.: 155 mm/52-caliber howitzer
Caliber Bore diameter of the main gun or rifle. Larger throws heavier projectiles; not simply better — ammunition commonality matters.: 155 mm
Max firing range Maximum range of the main gun or rocket artillery (with assisted/extended-range munitions where noted). Higher extends reach.: 40 km

Stronger than 43% of artillery systems

Physical

Dimensions, weight and crew.

Length Overall length including gun/probe where applicable.: 11.7 m
Combat weight Fully loaded weight. Lighter eases transport and bridging limits; heavier often means more armor.: 48,000 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.: MTU 8V199 diesel
Engine power Engine output power. Higher moves more weight faster.: 1,000 hp

Top 8% of artillery systems
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.: 120

Stronger than 18% of artillery systems
Operator countries Number of countries operating the system. More operators means broader support ecosystem.: 2

Stronger than 36% of artillery systems
