Russia’s full-scale invasion of Ukraine has forced the West to rethink defense production at scale. One of the clearest symbols of the war’s brutal logic is the 155 mm artillery shell – a standard NATO round and the core of modern firepower on a positional battlefield. As Ukraine burns through thousands of shells daily, the U.S., Germany, and Poland are racing to meet demand. But can they keep up?
Why 155 mm Ammunition Is So Crucial
The 155 mm round is the standard caliber across NATO and is compatible with howitzers such as the M777, Krab, PzH 2000, and Caesar. It’s essential for suppressing enemy positions, destroying fortifications, and conducting counter-battery fire.
Ukraine currently uses between 5,000 and 7,000 shells daily — which adds up to around 2.1 million per year. That’s more than global production capacity in 2022.
United States – The Giant Awakens
Before the war, U.S. production of 155 mm shells was around 14,000 per month – a figure that reflected peacetime assumptions more than battlefield realities.
Since 2022, the Pentagon has significantly ramped up efforts. By mid-2025, production reached approximately 40,000 shells per month, with a target of 100,000 monthly by the end of the year. That would bring annual production to over 1.2 million rounds.
New production lines have opened in Pennsylvania, Texas, and other states – and the U.S. military is treating this like a wartime mobilization.
Germany – Rheinmetall Goes Big
Germany, long criticized for being a “sleeping giant” in defense manufacturing, is catching up quickly. Rheinmetall, one of Europe’s largest arms producers, plans to manufacture 700,000 shells annually by 2025 and scale up to 1.1 million by 2027.
New factories – including a major site in Unterlüß – are being built to supply the Bundeswehr and NATO partners. Rheinmetall has even positioned itself as the future “arsenal of Europe.”
Poland – Fast-Tracking Industrial Expansion
Poland, one of Ukraine’s staunchest supporters, is also building up capacity. In April 2025, the Polish Armaments Group (PGZ) received 2.4 billion PLN (over $600 million) in state funding to expand 155 mm shell production.
Plans include three new factories, with a target of reaching 150,000 shells per year by 2027. Poland aims not just to cover its own needs but to become a regional supplier for NATO’s eastern flank.
Europe – Waking Up, But Still Lagging
Europe’s defense industry operated for decades in “just-in-time” mode – minimal stockpiles, outsourced supply chains, slow procurement cycles. The war changed everything.
The EU launched the ASAP program (Act in Support of Ammunition Production) to boost shell manufacturing via subsidies, shared contracts, and faster coordination. However, many countries still act individually, and efforts to build a unified defense production strategy remain fragmented.
Some states, like the Czech Republic, have taken matters into their own hands by organizing foreign purchases on behalf of Ukraine. Others, like France or Sweden, are expanding domestic production but remain limited in scale.
Production vs. Usage: The Numbers
Even with expanded capacity, the combined output of the U.S., Germany, and Poland barely meets Ukraine’s wartime needs – and that doesn’t even account for NATO’s own reserve requirements.
| Country | Target Annual Production | Ukraine’s Annual Use |
|---|---|---|
| USA | 1,200,000 | 2,100,000 |
| Germany | 1,100,000 | 2,100,000 |
| Poland | 150,000 | 2,100,000 |
Conclusion: A War of Logistics and Industry
Modern warfare isn’t just fought on the battlefield – it’s fought in factories. The 155 mm artillery shell is now a strategic resource. And while Western production is increasing, it still falls short of demand.
Europe is finally mobilizing its industrial base, but time is short. Nations like Poland are stepping up, but even with support from the U.S. and Germany, long-term security depends on rapid, scalable, and cooperative production strategies.
