155mm Artillery Shell Production EU 2026: Race to Supply Ukraine
Artillery ammunition has been the single most important supply constraint in Ukraine's war. Russia fires 5–10 million shells per year; Ukraine needs millions to compete. Europe's pre-war 155mm production capacity barely covered training needs. Since 2022, a massive industrial mobilization has attempted to scale to wartime requirements — with significant progress but persistent shortfalls that continue to shape the battlefield in 2026.

Why 155mm Shells Are the Decisive Resource
Modern high-intensity warfare is fundamentally an industrial war. The side that can sustain the higher rate of artillery fire — maintained over months and years, not days — creates cumulative attrition that eventually collapses enemy forces. During WWI, this was called "shell hunger." In Ukraine, it manifests as rationing fire: Ukrainian commanders limiting guns to 20 shells per day when 200 would be optimal.
Russia inherits massive Soviet-era ammunition stockpiles and domestic production capacity running at wartime rates. By 2023–2024, Russian 152mm and 122mm production reached an estimated 3–5 million shells per year. Combined with drawn-down stockpiles from Soviet depots plus North Korean deliveries (1M+ shells from 2023), Russia fires 20,000–40,000 rounds per day during active operations.
Ukraine's entire war effort depends on closing — or at least narrowing — this firepower gap.
Pre-War Baseline Production
Before February 2022, European NATO members collectively produced approximately 300,000–400,000 155mm shells per year. This covered standing peacetime military requirements — replacing training expenditure, maintaining minimum war stocks — but was never designed for industrial-scale warfare.
The United States produced ~93,000 155mm shells per year in 2022. By comparison, Russia was producing at a rate already 10× higher. The baseline gap was enormous.
The Scale-Up Effort 2022–2026
The EU launched its first-ever joint ammunition procurement initiative in 2023 — the Act in Support of Ammunition Production (ASAP), committing €500M to incentivize production increases. This was followed by a commitment to procure 1 million shells for Ukraine within 12 months (by March 2024).
That target was not fully met in the timeline — approximately 700,000–900,000 shells were delivered or contracted by end of 2024. However, the production investment drove a genuine structural increase: European production capacity roughly quadrupled from pre-war levels to reach ~1.3 million rounds/year by late 2025.
The USA simultaneously expanded from 93,000 to 100,000 shells/month (1.2M/year) by 2025 — a massive 15× increase from pre-war. South Korea also became a key supplier, delivering ~500,000+ shells through US end-user certificates in 2023–2024.
Major European Producers

155mm Production by Key Source 2022–2026
| Source | 2021 (Pre-War) | 2022 | 2023 | 2024 | 2025 | 2026 (Target) |
|---|---|---|---|---|---|---|
| EU (combined) | ~300–400K | ~350–450K | ~600–700K | ~900K–1.1M | ~1.2–1.3M | ~1.5–1.8M |
| United States | ~90K | ~100K | ~480K | ~900K–1M | ~1.1–1.2M | ~1.5M+ |
| South Korea | Domestic use only | ~100K (indirect to US) | ~300–500K (via US) | ~400–500K | ~400–500K | ~500K |
| Russia (152/155mm combined) | ~1–1.5M | ~2M | ~3–4M | ~4–5M | ~4–5M | ~4–5M (est.) |
Supply Chain Bottlenecks
Despite the scale-up, significant bottlenecks persist as of 2026:
- Powder/propellant: The most critical bottleneck. Nitrocellulose and other propellant intermediaries require specialized chemical plants with long lead times. European propellant capacity is well below shell casing and projectile body production — creating a "guns but no powder" problem.
- Fuzes: Electronic and mechanical fuze production requires semiconductor components and precision manufacturing. Extended fuze production timelines create a second bottleneck independent of the shell body chain.
- Shell steel: High-grade steel for shell bodies requires specifically certified mills. EU steel supply chains were strained in 2022–2024 amid broader industrial demand.
- Skilled labor: Shell filling and explosives operations require specially trained workers — safety regulations limit how quickly new workers can be certified to handle explosive components.
- Quality control: Artillery shells are high-precision items — dud rates increase if quality control is compromised. Rapid scale-up creates risk of quality issues that could endanger Ukrainian gun crews.
Non-EU Sources: USA, South Korea, Japan
Western allies outside the EU have been critical to bridging Ukraine's shell gap:
United States: The most significant single source. US 155mm production expanded from ~7,000/month in 2022 to ~100,000/month by 2025 — a ~14× increase driven by Army contracts awarded to General Dynamics Ordnance, BAE Systems, and others. US shells dominate Ukraine's 155mm inventory.
South Korea: With the largest 155mm production capacity in Asia, South Korea supplied shells via US end-user arrangements. South Korean political constraints (reluctance to be seen as directly arming Ukraine) mean recent supplies have been channeled through US or third-party mechanisms.
Japan: Explored mechanisms to supply shells in 2025, loosening some export restrictions. Japan produces significant 155mm quantities for its own Ground Self-Defense Force.
Ukraine Consumption vs Supply
| Period | Est. Daily Consumption | Monthly Need | Monthly Supply (est.) | Gap |
|---|---|---|---|---|
| 2022 (peak) | ~4,000–6,000/day | ~120–180K | ~40–60K | Large deficit |
| 2023 (high intensity) | ~4,000–7,000/day | ~120–210K | ~80–120K | Moderate deficit |
| 2024 | ~3,000–5,000/day | ~90–150K | ~120–160K | Near balance (some periods) |
| 2025 | ~2,000–4,000/day | ~60–120K | ~150–180K | Modest surplus (allows stockbuilding) |
| 2026 (projected) | ~2,000–4,000/day | ~60–120K | ~170–200K+ | Surplus if consumption moderate |
2026 Outlook and Projections
The strategic artillery ammunition picture in 2026 is dramatically improved versus 2022–2023 but remains fragile:
- EU production capacity continues to grow as 2023–2024 investment comes online through 2026
- US production at ~100,000 shells/month provides a substantial foundation
- The US political environment under the Trump administration creates uncertainty about sustained US supply commitments to Ukraine — Europe accelerating domestic production as insurance
- Propellant remains the most critical bottleneck — multiple EU programs to expand nitrocellulose capacity are ongoing but not yet delivering at full scale
- Ukraine's own domestic production program for artillery shells (Soviet calibers initially, with 155mm under development) could add modest capacity by 2026–2027
- Russian shell production advantage persists — Russia still fires at 5–10× Ukraine's sustainable rate, making conservation and precision (Excalibur, GMLRS) increasingly important
