Rheinmetall will supply 444 million euros ($521 million) worth of artillery ammunition to an undisclosed Eastern European country under a contract commissioned by the US.
The German arms maker will deliver both 155mm M107 projectiles with M4A2 propellant charges and 105mm M1 shells.
The M107 is a standard high-explosive 155mm artillery round widely used by NATO forces and designed for long-range indirect fire. Meanwhile, the 105mm M1 projectile remains a staple of lighter artillery systems, valued for its mobility and effectiveness in supporting maneuver units.
Out of the total contract amount, at least 170 million euros ($199 million) was booked earlier as a pre-order, while the remaining 274 million euros ($321 million) was recently confirmed.
Shipments are scheduled to start in 2026 and be completed by June 2027.
Fixing Strained Arms Supply
The latest deal, structured through Global Military Products on behalf of the US government, comes as ammunition stocks in Europe are being stretched and allied nations are scrambling to secure reliable supply chains.
Europe has for years relied on US and allied stocks to sustain heavy artillery campaigns, especially in the context of the war in Ukraine, but those stocks are also strained.
This deal is aligned with a broader pivot that sees the use of defense firms to re-shore or expand production capacity within the continent and its periphery.
Rheinmetall, for example, set a goal of producing up to 1.5 million 155mm artillery shells annually by 2027. It also inaugurated in August 2025 a large munitions factory in northern Germany and signed partnerships for ammunition production facilities in allied countries.
