Firestorm Labs has raised $82 million in a Series B round to scale xCell, its containerized drone manufacturing platform that fits an industrial-grade 3D printer inside a standard shipping container and produces complete drone systems in under 24 hours. The round brings total capital raised to $153 million.
Washington Harbour Partners led the round, with Lockheed Martin and In-Q-Tel participating — a combination that signals both strategic interest from a prime contractor and intelligence community validation for the underlying concept.
What xCell Actually Does
The core problem xCell addresses is supply chain exposure in contested environments. Fixed drone manufacturing facilities are stationary targets. Shipping components across thousands of miles introduces lead times measured in weeks or months and creates interdiction risk that conventional logistics planning struggles to mitigate.
xCell moves production to the point of need. A standard shipping container houses an HP industrial 3D printer capable of producing drone airframes and components configured for specific mission requirements — electronic warfare payloads, surveillance packages, or other specialized configurations — without returning to a fixed factory. The containerized format means the manufacturing capability is as mobile as any other piece of military equipment.
The platform is currently operational at Air Force facilities in Florida and New York. Firestorm has also deployed xCell in the Indo-Pacific, where it is targeting full operational capability within two years — a timeline that maps directly onto US military planning horizons for that theater.
Beyond Drones
The Army has used xCell to 3D-print replacement parts for Bradley Fighting Vehicles on-site, cutting around procurement delays that typically run months through conventional supply channels. That use case matters for the funding story: it means xCell’s addressable market extends beyond drone manufacturing into broader battlefield logistics, which expands both the revenue opportunity and the strategic rationale for defense investor participation.
Firestorm’s current revenue comes from hardware sales and government contracts, including an Air Force contract potentially worth $100 million. With $153 million in total capital and operational deployments across two services and an overseas theater, the Series B funds a scaling phase rather than a proof-of-concept. Indo-Pacific deployment timelines and additional service contracts will be the metrics to watch over the next 18 months.
