Russian artillery range and accuracy is inferior to the U.S. and Germany's:
The towed M777, one of the U.S. howitzer models to be delivered, has a maximum range of 24km to 30km depending on the munitions used — more for the latest models — outstripping most Russian equivalents. It also has a better capability for digital targeting, meaning fewer shots fired to strike a target.
State of the art German-made Pzh 2000s are also on their way from the Netherlands. A more than 60-tonne, armored, self propelled and self loading 155mm howitzer, the gun has integrated GPS, weather and other systems as well as a maximum range in excess of 60 km with rocket assisted shells. That could allow it to fire out of range of Russia’s artillery.
The Russian military may soon become a sitting duck to devastatingly accurate and long range strikes. The 60km range of the Pzh 2000 means that a single Pzh 2000 sitting in Myoklaiv can deliver ten GPS-guided 155mm howitzer shells into Kherson within one minute. Terrifying.
