If Ukraine can hang on another 8'ish months, their supply of artillery shells is going to grow exponentially as we move towards 2025.
Here is recent breakdown of expanding Western artillery shell production capacity. It will increase substantially throughout 2024, and by 2025 the West's shells production will be more than enough to keep Ukrainian artillery pieces firing is near perpetuity.
2025 capacity...
USA DOD: 1,200,000
Rheinmetall: 700,000-800,000
BAE: 500,000-750,000
Nexter: 120,000-150,000
Europlasma: 150,000-180,000
General Dynamics: 50,000-75,000
South Korea: 200,000-300,000
Poland: 75,000-100,000
Czech Republic: 75,000-100,000
Sweden: 75,000-100,000
Finland: 75,000-100,000
Ukraine domestic: 75,000-100,000
All other sources: 200,000-300,000
By 2025 the West will have the capacity to produce between 4,000,000-4,500,000 artillery shells per year. If 2,500,000 of those shells go to Ukraine, they'll have the capacity to fire more than 208,000 shells per month, a sustained rate of 7,000 shells per day. Among those shells will be tens of thousands of GPS guided shells, that are extremely deadly when combined with Western counter battery RADAR.
Afaik, US DoD plants are operated by General Dynamics and BAE system in USA. Counting them sperately would be misleading.
