Germany has reportedly planned to procure field artillery pieces, starting with dozens of howitzers, to help replenish the billions of dollars worth of military aid they sent to Ukraine.

According to Reuters, Germany plans to purchase up to 28 self-propelled howitzers to restock its diminishing arsenal, which the country began supplying to Ukraine last year to ramp up the latter’s effort to fight against the Russian invasion.

In the document the news outlet reviewed on Monday, Berlin’s defense ministry said to procure at least ten howitzers from a local manufacturer, Krauss-Maffei Wegmann (KMW), at the cost of 180 million euros ($194 million). They are also seeking an option for eighteen more self-propelled artillery systems.

Likewise, the defense ministry intends to activate procurement options for 12 more howitzers, effectively replacing all weapons transferred to Kyiv while providing spares to the Ukrainian forces.
