US: 155mm Krab SPHs play important role in Ukraine, shells are problem

WASHINGTON — Polish Krab self-propelled howitzers play a significant role in the war in Ukraine, the American television CNN reported in a report from Donbass. In the material, Ukrainian soldiers praise the accuracy and modernity of these guns.

The report shows Krab shelling Russian positions from a distance of 30 km, as the entire operation, ie. “They are much better than what we had before. The mobile [equipment] gets us out of harm’s way quickly,” Krab Battery Commander said, a former math teacher Vasil, who underwent two weeks of training on how to operate a gun, told CNN after the shot.

The soldier also praised the advanced and “comfortable” Polish Topaz fire control system and the precision thanks to navigation, including GPS. These elements provide the Ukrainian gunners with very good situational awareness. This included having to make the “Crabs” “popular” with Ukrainians, while Kyiv ordered another 54 howitzer guns in addition to those donated by Poland [in the first batch – 18 guns]. The value of the order to be executed by Huta Stalowa Wola is PLN 2.7 billion.

However, CNN’s report suggests that the problem may be the availability of ammunition, as well as the integration of equipment from different NATO countries. A television reporter also noted that despite modern weapons supplied by the West, some Ukrainian soldiers lacked proper footwear and communication equipment.
