Polish Ministry of Defense to Send 18 AHS Krab Self-propelled Howitzers to Ukraine

Polskie Radio reported that the Polish Ministry of Defense (Ministerstwo Obrony Narodowej, MON) is transferring 18 AHS Krab tracked self-propelled howitzers, which are currently the latest type of artillery weapon deployed in the Polish Army to Ukraine. Polish sources say the Polish army has already trained 100 Ukrainian artillerymen to operate these weapons. Polish authorities have not officially confirmed the media revelations. This is related to information policy. Thus, together with 12 PzH 2000 from Germany and the Netherlands, Ukraine will already have 30 tracked 155-mm self-propelled guns.

The AHS Krab (Crab) is a 155 mm NATO-compatible self-propelled tracked howitzer designed in Poland by Centrum Produkcji Wojskowej Huta Stalowa Wola combining K9 Thunder chassis, a AS-90M Braveheart turret with 52-calibre gun and WB Electronics “Topaz” artillery fire control system. The 2011 version used a Nexter Systems barrel and UPG chassis. The 2016 production batch utilize the K9 chassis and a Rheinmetall barrel. The KRAB can be ready to fire in less than 1 minute and leaves its firing position in 30 seconds. In December 2016, The Polish Company Huta Stalowa Wola (HSW) has signed a contract for the delivery of artillery vehicles to the Polish Army for a total amount of €1 billion including 24 Krab 155mm self-propelled howitzer armoured vehicles. As of 2016 full-rate production of 120 Krabs for Polish Army has started with 16 guns completed and deliveries to be completed by 2024.

Standard equipment of the KRAB 155mm self-propelled howitzer includes night vision for the driver, direct fire sight, NBC protection system, automatic fire suppression system and a laser range-finder. The vehicle also integrates a navigation system and a DD-9620 terminal providing target information. The muzzle velocity measuring system above the main gun feeds information to the fire-control system. The ZZKO TOPAZ fire-control system controls the turret, gun layer computer and other subsystems. The KRAB is also fitted with an auxiliary power unit for the turret to ensure the use of on board electrical and electronic equipment during shut down of the main diesel engine.

The KRAB turret is mounted at the rear of the tracked chassis. Turret traverse is through a full continuous 360º and weapon elevation is from -3.5° to +70°. Elevation and traverse drives are both electric and operate at a rate of 10°. Main armament of the KRAB consists of one 155mm 52 calibre designed and manufactured by BAE Systems. The gun can fire all standard 155mm NATO projectiles with a range from 4.7 to 40 km. An automated loading system enables the gun to fire with a burst rate of three rounds in fewer than ten seconds, an intense rate of six rounds a minute for three minutes and a sustained rate of two rounds a minute.
