Building a Resilient and Secure Battery Supply Chain to Support Military Drone Operations
Summary
As drones transition from niche equipment to mass-consumption weapons systems, militaries are being forced to treat batteries with the same operational seriousness historically reserved for fuel and ammunition. The U.S. Department of Defense's Drone Dominance Program is rapidly scaling one-way attack drone production from tens of thousands to over 200,000 units by 2027, creating significant and urgent demand for reliable battery supplies while simultaneously working to reduce dependence on Chinese supply chains. Because the commercial battery market dwarfs the defense sector by two to three orders of magnitude, the military remains a price taker in a global battery economy dominated by electric vehicles, consumer electronics, and Asian manufacturing, making it vulnerable to supply disruptions at critical points that could directly halt combat operations. A three-part resilience framework has been proposed to address these vulnerabilities, encompassing the creation of a strategic battery reserve, investment in domestic and allied battery manufacturing, and leveraging U.S. technological innovation to develop advanced battery chemistries. Lessons drawn from the conflict in Ukraine have further underscored the tactical burden of battlefield electrical logistics, highlighting how vulnerable charging infrastructure, battery degradation, and limited power access can critically constrain drone operational capacity.
Key Takeaways
- 1. Drone batteries serve multiple logistical roles simultaneously — functioning as fuel for reusable drones, expendable components for one-way attack drones, and shelf-life-limited parts for loitering munitions
- 2. Defense battery demand reached 4.3 gigawatt-hours in 2025, with drones accounting for 39% of that demand, yet this remains commercially small relative to the broader global battery market
- 3. The U.S. military is a price taker in the global battery economy, making it dangerously dependent on commercial supply chains that could be disrupted at critical chokepoints
- 4. A three-part resilience strategy — strategic battery reserves, domestic/allied manufacturing investment, and R&D innovation — is recommended to reduce supply chain vulnerabilities
- 5. Battlefield experience in Ukraine revealed that charging infrastructure, battery depletion, and power logistics represent significant tactical weaknesses that could be magnified in a Pacific conflict scenario
