The Polish Krab self-propelled gun supplied to Ukraine has shown that this is a weapon that shows good performance in combat, but the continuous high-intensity firing of the gun has led to the damage to the gun barrel.

Recently some images were published by the Russian Avia Site, showing that the Krab self-propelled howitzer has been “ripped off”, the result of high-intensity combat. Previously, the German-supplied Self-propelled Artillery Pzh2000 was also damaged in Ukraine due to heavy use.

It is known that Poland has given Ukraine 18 units of self-propelled Krab Artillery Systems.

The Russian Avia Site, published the following information about the Krab Artillery System, “The Ukrainian army lost the first Polish howitzer AHS Krab.

During the next shelling with the use of the Polish howitzer AHS Krab, the barrel of the latter was torn off. This was not due to the detonation of ammunition inside the bore, but probably due to a defect or severe wear of the howitzer barrel, as indicated by the presence of damage characteristic of this. Given the lack of spare parts, the repair of the Polish howitzer may take sometime.
