The howitzer has an automatic loading system, providing a rate of fire of one round every 15 seconds or a burst-fire rate of three rounds every 25 seconds. The loader has 23 ready rounds, with seven more rounds stored in the hull. Including manual reloading of the charge, the overall firing rate is normally is one round per minute for one hour. Intense firing is four rounds in one minute. Sustained fire is one round every three minutes for an indefinite period. A wide variety of munitions includes specially developed Simmel ammunition with a range of 24.7 km and rocket-assisted projectiles with a range of 30 km.
The turret is hydraulic with manual backup, and has 360 degree rotation with elevation limits of -4 to +70 degrees. It has its own auxiliary power supply which conserves fuel for the main engine.| Palmaria | |
