German Artillery Donated To Ukraine Is Already Failing After Just Weeks Of Use | ZeroHedge
Barely a month since their delivery, the first German armored self-propelled guns have already ceased service in Ukraine, according to a report by German newspaper Der Spiegel.
The German Ministry of Defense was informed by Kyiv last week that an error message appeared on the cannons and that several of them needed to be repaired. According to the Bundeswehr, the reason behind the malfunction may be that the Ukrainians are firing the guns more intensively than the technology is capable of.
This means that the stress on the loading systems may be too high. Another problem could be that the soldiers reportedly fire the units from too far away with the special ammunition; the smart grenades used by these cannons were meant for shorter-range, precision hits.
The Bundeswehr explained that misuse of the weapons could have contributed to a more accelerated wear and tear. Despite the problems, however, they agreed to supply Ukraine with additional weapons packages.
