The conducted trials included e.g. measuring the initial velocity of projectiles and the accuracy The tests were an element of verification of Krab howitzers potential and the correctness of adaptation of the gun-howitzer to the Polish army's requirements, but they also served to perform measurements forming the basis of development of range tables for the new artillery equipment of the Polish field artillery. The test-firing process was also an opportunity to train and make the gun-howitzer crews "play" well together in the scope of preparing the crews to fire, managing the fire-control system, adjusting the artillery fire and providing logistic support, including loading shells from an ammunition supply vehicle. The March tests were the culmination of the multi-stage trials carried out from October 2015 to April 2016, finished with MOD's declaration of type conformity with the relevant tactical-technical assumptions. Firing tests included use of shells from two different manufacturers and modular propellants of different energy. The trials involved also checking the behavior of suspension system and hull at every position of the turret against the carrier's longitudinal axis, including the turret being turned 90° to the left and to the right with respect to the longitudinal axis, and turned 180°, back to front. Apart from that, during 2016 tests, the tested vehicle traveled over 4,000 km (required was 3,000 km), reaching a maximum speed of 67 km/h (required 60 km/h), and range of approx. 500 km (required 400 km). The testing procedure was also about assessing the wear of some sub-assemblies and parts (e.g. track elements) and verifying the operating assumptions. There were also high and low temperature chamber tests conducted at the Military Institute of Armoured and Automotive Technology (PL: WITPiS), with the temperatures ranging from –50 o C to www.fragoutmag.com
