Scale of the Shortage
Artillery dominates modern high-intensity warfare: in Ukraine, artillery accounts for the majority of battlefield casualties on both sides. Shell availability therefore directly and immediately translates to the ability to hold and contest ground:
| Period | Ukraine Daily 155mm Fire Rate | Russia Daily Artillery Rate | Approximate Ratio |
|---|---|---|---|
| Early 2022 | 2,000–3,000+ rounds/day (peak) | 30,000–50,000 rounds/day (peak) | ~10:1–20:1 Russian advantage |
| Late 2022 (Kharkiv/Kherson) | 5,000–7,000 rounds/day | 20,000–30,000 rounds/day | ~4:1–5:1 |
| Mid-2023 counteroffensive | 3,000–5,000 rounds/day | 20,000–30,000 rounds/day | ~5:1–8:1 Russian advantage |
| Early 2024 (Avdiivka) | ~2,000 rounds/day (shortage) | 25,000+ rounds/day | ~10:1 Russian advantage |
| Mid-2024 (post-US package) | ~4,000–5,000 rounds/day | 20,000–25,000 rounds/day | ~5:1 |
| Early 2026 | ~4,000–6,000 rounds/day | ~15,000–20,000 rounds/day | ~3:1–4:1 Russian advantage |
Operational Impact: Losing Ground
The shell shortage's operational consequences in 2023–2024:
- Ukrainian units defending Avdiivka reported cases of being allocated 10–20 shells per position per day versus Russian attackers firing hundreds at each defended building; this severely limited Ukraine's ability to suppress Russian infantry
- Counter-battery fire — the use of artillery to destroy Russian artillery — nearly stopped when Ukraine was conserving shells; this freed Russian artillery from degradation and allowed sustained barrages
- Ukraine's 2023 counteroffensive was heavily constrained by ammunition limitations; Ukrainian brigades attacking Russian fortification belts reported running low mid-battle, slowing advances that might have been sustained with more ammunition
- Avdiivka fell in February 2024 in direct correlation with Ukrainian ammunition shortage; Ukrainian forces withdrew under conditions of extreme fire imbalance
- The shortage created a negative operational feedback loop: fewer shells → less counter-battery fire → more Russian artillery operating freely → more Ukrainian casualties → fewer remaining effective defenders → more ground lost
Russian Artillery Advantage
Russia's artillery advantage derived from multiple sources:
- Soviet legacy stockpiles: Russia inherited enormous stockpiles of 122mm and 152mm shells from Soviet era — estimates range from 2 to 10 million rounds depending on condition — providing a years-long buffer even at high consumption rates
- North Korean supply: An estimated 1–3+ million artillery shells (primarily 122mm and 152mm) delivered from North Korea from mid-2023 onward, compensating for Russian domestic production shortfalls and accelerated consumption
- Domestic production: Russia has three main artillery ammunition production facilities (Kirov machine-building, Ulyanovsk, Caspian region plants) reportedly running 2–3 shifts and producing ~3–4 million rounds/year by 2024
- Iranian ammunition: Some reporting suggests Iranian-produced 122mm compatible rounds were also supplied alongside Shahed drone deliveries, though less definitively confirmed than North Korean supply
International Supply Response
- US supplemental package (April 2024): $61B including ~800,000 155mm shells drawn from US Army stockpiles and ordered into production for future delivery; the most significant single injection into Ukraine's ammunition supply
- Czech Ammunition Initiative (from Feb 2024): Coordinated non-EU sourcing of ~500,000–800,000 shells by end of 2024 at an estimated cost of ~€1.5B contributed by 20+ nations
- EU EDIRPA/ASAP production ramp: EU domestic production rising from ~400,000 rounds/year (2022) toward 1.5–2M rounds/year target
- Bilateral donations: South Korea (indirect), various Eastern European NATO states transferring national stockpiles and ordering replacement production
- Combined effect: by mid-2024 Ukraine's daily fire rate had roughly doubled from the late-2023 trough; the most acute shortage was resolved but the underlying Russia-Ukraine fire ratio remained significantly in Russia's favour
Ukraine's Own Production Capacity
- Ukraine's pre-war artillery ammunition production was minimal — the former Soviet system produced most ammunition centrally in other republics that became Russian territory (and Belarus)
- During the war Ukraine has scaled up some domestic production: primarily 122mm Grad rockets and mortar rounds; some 152mm compatible production with international components
- NATO-calibre (155mm) domestic production is a stated priority via the Ukraine Defence Joint Ventures programme; Germany's Rheinmetall has discussed in-Ukraine 155mm production but this is not yet operational at scale
- Ukraine's artillery manufacturing challenge is compounded by factory vulnerability — Russia has deliberately targeted Ukrainian defence industrial facilities with missiles, requiring geographic dispersal and hardening
Calibre Complexity
Ukraine operates artillery systems across multiple incompatible calibres, creating a logistics challenge:
- 155mm: NATO standard; required by Western howitzers (M777, Caesar, PzH 2000, M109A6, FH70, Howitzer M109)
- 152mm: Soviet standard; older 2S3, 2S5, 2S19, D-20 systems still in service; supplied by Eastern members and through non-NATO market
- 122mm: Soviet standard for BM-21 Grad, D-30 howitzers; widely available from legacy stockpiles; North Korea delivered compatible shells
- 120mm: Mortar standard (both NATO and Soviet); relatively well supplied
- The two-track supply chain (NATO 155mm + Eastern-legacy 152mm/122mm) creates planning complexity and prevents full interoperability with NATO stocks
- Ukraine's declared long-term intent is to fully transition to NATO-calibre 155mm as old Soviet systems wear out or are destroyed, but this transition will take years
Status in Early 2026
- The most acute shortage of early 2024 has been resolved — Ukraine is no longer facing unit-level ammunition blackouts of a few shells per day
- Russia maintains a significant fire-ratio advantage, currently estimated at ~3:1–4:1 in artillery exchange rates overall — down from the catastrophic ~10:1 of early 2024 trough
- Ukraine's adaptation: significantly increased FPV drone usage as partial artillery substitute (drones have taken artillery's role in some counter-infantry missions, as they are cheaper and more abundantly available); glide bombs have substituted for some long-range artillery missions
- Uncertainty with US political situation (Trump administration reducing supplemental commitment) has pushed EU and bilateral sources to increase their share; the Czech initiative has continued at reduced but ongoing pace
- While the shortage is no longer catastrophic, sustained artillery undersupply versus Russia remains a structural constraint that limits Ukrainian offensive capability and imposes defensive costs
Frequently Asked Questions
What does it actually mean to run out of shells mid-battle?
In practice, "running out" rarely means absolute zero — it means ration levels so low that artillery can no longer perform its core missions. When a defending unit is allocated 20 shells per position per day while facing Russian attackers with near-unlimited consumption, the defender cannot: suppress Russian infantry assaults in open ground, conduct counter-battery fire against Russian mortars and artillery, interdict Russian logistics bringing fresh troops to the attack, or neutralise Russian observation drones directing fire. The defending unit is essentially fighting blind and unprotected while the attacker enjoys fire support. In this situation casualties mount faster, soldiers withdraw from exposed positions, gaps appear in the line, and Russian forces exploit them. The arithmetic is brutal: fire imbalance translates almost directly into ground lost.
Has Ukraine learned to fight with fewer shells?
Yes, substantially. Ukrainian forces have developed significant expertise in shell-conservative tactics. FPV drone strikes are now heavily used for the counter-infantry mission that previously consumed enormous quantities of shells — a $400 drone replacing what might have been 10–20 howitzer rounds ($3,000–$8,000 worth). Precision-guided rounds (Excalibur, Krasnopil when captured, Copperhead) are used for high-value targets to improve hit probability per round. Counter-battery fire has become more intelligence-driven rather than volume-based. Ukraine has also pushed production of domestic rocket munitions (Grad 122mm) and mortars to reduce 155mm dependency for certain missions. These adaptations are genuine military innovation — Ukrainian artillery units in 2026 are accomplishing missions with 30–50% fewer shells than they would have consumed using 2022-standard Western doctrine.
When will Russia run out of artillery ammunition?
Russia shows no immediate signs of running out. Conservative estimates put Russia's remaining usable stockpile at several million rounds even after nearly four years of high-consumption warfare. North Korean deliveries of 1–3+ million rounds have directly offset Russian consumption shortfalls. Russian domestic production is running at ~3–4 million rounds/year across multiple calibres. Western analysts who predicted Russia would exhaust its artillery ammunition in 2022–2023 have been consistently wrong; the Soviet logistics inheritance was larger than anticipated, and North Korea's willingness to supply strategically compensated for gaps. The more relevant constraint on Russia is not quantity but quality: some reports indicate Russian stockpile quality is degrading (mis-propellant charges, dud rates increasing), and the transition away from precision-guidance to legacy volume fire has quality implications. But pure quantity constraint is not an imminent Russian problem.
