Propellant and Powder Production in Ukraine 2026: The Hidden Foundation of Ammunition Self-Sufficiency

1. Why Propellant is the Critical Bottleneck

In the analysis of ammunition supply chains, propellant (gunpowder) is often overlooked in favor of the more visible components — warheads, shell casings, fuzes, and finished rounds. Yet propellant is arguably the most fundamental bottleneck in ammunition production, for a simple reason: it is a specialty chemical manufactured at dedicated energetics facilities that operate under unique safety, environmental, and security requirements. You cannot rapidly convert a generic chemical plant or a food processing facility into a propellant manufacturer.

The starkness of this constraint emerged clearly in the global response to Ukraine's ammunition needs. Western nations that could rapidly source steel shell casings and brass from commercial suppliers found propellant to be the limiting factor in accelerating artillery ammunition production. Powder works across NATO reached capacity constraints within months of accelerated contracting in 2022–2023.

For Ukraine specifically, domestic propellant production is the single most important step toward genuine ammunition self-sufficiency. A country that can produce its own propellant can, in principle, manufacture all its own ammunition given sufficient time, tooling, and raw materials. Without domestic propellant, every ammunition component advantage is hostage to foreign supply chains.

2. Pre-War Ukrainian Propellant Capacity

Ukraine inherited Soviet-era propellant manufacturing facilities as part of the USSR's distributed defense industrial base. The key pre-war facility was the Shostka Powder Works (Шосткинський казенний хімічний завод — ShKhZ) in Sumy Oblast — one of the oldest chemical/munitions facilities in the former Soviet Union, with roots dating to the 19th century.

Shostka produced primarily single-base nitrocellulose propellant for small arms ammunition (5.45×39mm, 7.62×54mmR) and some double-base propellant for rocket systems. Its capacity was sized for peacetime consumption rates — essentially a maintenance production operation preserving institutional knowledge rather than a surge capacity facility.

Shostka's Vulnerable Location

A critical strategic problem emerged early in the war: Shostka is located in Sumy Oblast, approximately 60 km from the Russian border — within easy missile and eventually drone range. Operations at Shostka have been significantly complicated by security considerations, requiring dispersal of key operations, staff protection measures, and careful production scheduling to maintain output while minimizing vulnerability to targeted strikes.

3. Types of Military Propellant

Military propellant is not a single product but a family of chemically distinct formulations, each suited to different applications:

Single-Base Propellant (Nitrocellulose)

The simplest military propellant, consisting primarily of nitrocellulose. Used in small arms ammunition (most pistol and rifle calibers) and some artillery applications. Relatively straightforward to manufacture but requires controlled nitration chemistry.

Double-Base Propellant (Nitrocellulose + Nitroglycerin)

Higher energy density than single-base, used in many artillery propellant charges and some rifle ammunition. More energetic but also more sensitive during manufacture. The nitroglycerin component adds significant manufacturing hazard.

Triple-Base Propellant (adds Nitroguanidine)

Provides very high energy with lower flame temperature than double-base, valuable for large-caliber artillery where barrel erosion is a limiting factor. Used in 155mm NATO propellant charges. Most chemically complex and historically produced at very few specialized facilities globally.

Composite Propellant (Rocket)

Solid rocket propellant — typically HTPB (Hydroxyl-Terminated Polybutadiene) binder with ammonium perchlorate oxidizer and aluminum fuel — used in rockets and missiles rather than guns. Manufactured using different processes than gun propellant, at separate specialized facilities.

4. Wartime Production Challenges

Ukraine's propellant production expansion faced a perfect storm of challenges:

• Geographic vulnerability: Primary facility in Sumy Oblast is under constant threat of attack, requiring defensive operations, night-shift scheduling, and hardened storage
• Raw material sourcing: Nitrocellulose production requires cotton linters or wood pulp and concentrated nitric/sulfuric acids — supply chains disrupted by war and logistics constraints
• Safety constraints: Explosives and propellant manufacturing cannot be rushed without compromising safety — standard processes involve extended drying, conditioning, and stability testing cycles
• Worker expertise: Propellant chemistry requires specialized engineers and chemists; wartime mobilization drew personnel away from this sector before selective exemptions were applied
• Energy supply: Propellant manufacturing is energy-intensive; Russia's attacks on energy infrastructure created significant operational disruptions
• Export restrictions: Some propellant precursor chemicals require export licenses from producer countries; securing these approvals added time and bureaucratic complexity

5. Current Production Capacity Assessment

Ukraine has not publicly disclosed propellant production figures, for obvious operational security reasons. Drawing on available information — Ukrainian defense ministry statements, Western analyst assessments, and industry reporting — the following assessment is possible as of March 2026:

• Small arms propellant: Shostka and at least one other (undisclosed) facility operating at combined rates estimated to support several hundred million rounds of small arms ammunition per year — meaningful but still below full wartime demand
• Artillery propellant: The most constrained area. Ukraine relies primarily on imported artillery propellant charges (from NATO members) rather than domestic production. Domestic 152mm propellant production for legacy Soviet artillery maintains some output; 155mm NATO propellant domestic production is in its very early stages
• Rocket propellant: Ukraine maintains small-scale solid rocket propellant capability, primarily for domestically produced rocket systems. This has been scale-up priority given the importance of rocket artillery (MLRS) in the conflict
• Explosive fill (RDX/TNT): Closely related to propellant manufacturing, Ukraine maintains TNT and some RDX production capability of classified scale

Overall assessment: Ukraine has a propellant manufacturing base that covers a meaningful fraction of its small arms needs but remains heavily import-dependent for artillery propellant — the category most critical to the current conflict's operational dynamics.

6. Western Technical Assistance

The United States, UK, France, and Germany have all provided some level of technical assistance for Ukrainian propellant/energetics manufacturing capacity expansion. This assistance takes several forms:

• Technical consultancies: Propellant chemists and engineers from Western defense companies working under bilateral government arrangements to advise on process optimization and capacity expansion
• Equipment supply: Manufacturing equipment including mixers, extruders, granulators, and test equipment supplied under government aid packages
• Process documentation: Technical specifications for NATO-standard propellant formulations shared with Ukraine's defense industry to enable domestic production of compatible charges
• Supply of precursors: Western chemical companies authorized to export nitrocellulose and other propellant precursors to Ukraine under expedited licensing
• Investment: Several European defense companies have announced investments in Ukrainian energetics capacity, creating public-private partnership arrangements to accelerate capability development

The most strategically significant assistance has been for 155mm artillery propellant capability, which would allow Ukraine to manufacture complete artillery rounds domestically rather than importing the entire round from Western sources — a logistics and supply independence game-changer.

7. Import Dependency and Sourcing

In the interim period before domestic propellant capacity reaches sufficiency, Ukraine relies on a diverse import network:

• Czech Republic: Czech energetics companies (Explosia, Chemická továrna Alvernia) supply propellant as part of the Czech ammunition initiative for Ukraine
• Slovakia: ZVS Holding provides propellant components alongside ammunition supply agreements
• Poland: Nitro-Chem Bydgoszcz (one of Europe's largest propellant manufacturers) is a significant supplier
• United States: St. Marks Powder and other US energetics manufacturers supply propellant components under DoD contracts
• Norway: Nammo AS (Norwegian Ammotechs) supplies propellant alongside ammunition packages

The geographic diversification of propellant supply represents deliberate resilience architecture — no single supplier represents more than about 30% of Ukraine's total propellant import needs, protecting against single-source disruption.

8. The 155mm Artillery Propellant Supply Chain

155mm howitzer propellant is the most critical single propellant supply chain item in Ukraine's war. Each 155mm round requires a propellant charge comprising approximately 500–600 grams of propellant in modular bags. With Ukraine consuming (at peak) 6,000–8,000 rounds per day across all artillery calibers, and 155mm representing perhaps 25–35% of this, the propellant requirement runs to tens of tonnes per day.

Propellant Charge Types

NATO 155mm artillery uses modular propellant charge systems (MACS — Modular Artillery Charge System), particularly US M231/M232 MACS and European-standard JBU charges. These are not interchangeable with Soviet 152mm propellant charges, requiring completely separate supply chains.

Domestic 155mm Production Path

Ukraine's path to domestic 155mm propellant production involves:

1. Establishing triple-base propellant formulation capability (most chemically complex step)
2. Acquiring the specialized extrusion and granulation equipment for charge geometry
3. Qualifying the propellant against NATO partner testing standards to ensure compatibility with Western artillery pieces
4. Scaling production to militarily meaningful rates

Ukrainian officials have stated that steps 1–3 are effectively completed as of early 2026, with scale-up in progress. Full domestic 155mm propellant production at meaningful scale is targeted for late 2026 to 2027.

9. Small Arms Propellant

For small arms propellant (primarily single-base nitrocellulose for 5.45×39mm, 7.62×39mm, 7.62×54mmR, and now 5.56×45mm NATO), Ukraine's Shostka facility and any supplementary production have maintained output through the war. Small arms propellant production is less technically complex than artillery propellant, and Shostka's pre-war capability in this area remained largely intact.

The key development in small arms propellant is the addition of 5.56mm NATO propellant to the production slate — required to support Ukraine's transition to Western rifles and to achieve domestic 5.56mm ammunition production. This NATO-caliber propellant uses similar chemistry but different burn rates than Soviet calibers, requiring formulation adjustment and equipment calibration at Shostka.

10. Rocket and Missile Propellant

Solid rocket propellant for rocket artillery (BM-21 Grad, BM-30 Smerch, and imported HIMARS/M270 rockets) represents a separate manufacturing challenge. Ukraine has maintained some capacity for Soviet-standard rocket propellant, primarily supporting older BM-21 rockets manufactured or refurbished domestically.

The massive increase in drone usage has also driven demand for small rocket motors used in FPV drone warheads and in Ukraine's domestically developed loitering munitions. These applications use simpler rocket propellant formulations that are easier to manufacture in distributed small-scale facilities — an area where Ukraine's wartime industrial creativity has been most effective.

For imported rocket systems (HIMARS/M270 rockets, British Storm Shadow cruise missiles), propellant is supplied pre-integrated in the rocket motor and not separately manufactured in Ukraine — making these systems fully import-dependent for propulsion, though Ukraine is interested in domestic production arrangements for certain rocket types as a longer-term goal.
