Firestorm Labs raises $82 million for containerised drone factories

Firestorm Labs raised $82 million to expand a container-sized drone factory that can print airframes in under 24 hours, according to TechCrunch. The San Diego-based defence startup says its xCell unit fits in a shipping container and is already deployed with US Air Force research and special operations units. The round was led by Washington Harbour Partners, with investors including NEA, In-Q-Tel, Lockheed Martin and Booz Allen Ventures.

The pitch is less about a single drone model than about moving manufacturing to wherever the fight — or the supply-chain break — happens. Firestorm started as a drone maker, then pivoted after customers asked it to bring production closer to the front line, TechCrunch reports. In Ukraine, fixed factories and warehouses have become obvious targets, while drone designs change fast enough that traditional procurement cycles struggle to keep up. A mobile production line turns the vulnerability of a central plant into a smaller, relocatable asset, and it shifts the bottleneck from shipping finished systems to shipping raw materials and printer consumables.

That shift also changes who controls iteration. xCell uses an industrial-grade HP 3D printer to produce the body and shell, while weapons are added separately; Firestorm says the platforms can be configured for surveillance or electronic warfare and are capable of lethal operations. The company has a five-year global exclusive agreement with HP for the industrial 3D-printing technology used in mobile deployment units, giving it a choke point that looks more like a supplier relationship than a typical “buy drones” contract. When manufacturing becomes a software-and-materials pipeline, the party that owns the printer integration, design files and certification processes can decide what gets built, how fast it changes, and which customers get updates.

The funding arrives as the Pentagon elevates “contested logistics” into a critical technology priority — a recognition that modern conflicts punish long resupply lines and predictable depots. Firestorm says it makes money through hardware sales and government contracts across US military branches; an Air Force contract has a $100 million ceiling, with $27 million obligated so far, TechCrunch reports. The Army has used xCell to print replacement parts for a Bradley Fighting Vehicle on-site, a task that would otherwise take months, a detail that underlines the broader play: once a container can print drone components, it can print other hard-to-source parts too.

Firestorm says xCell is operational in the Indo-Pacific but declined to specify which units are using it, and it aims for full operational deployment there within two years. For now, the most concrete footprint is domestic: one unit with the Air Force Research Laboratory in Rome, New York, and another with Air Force Special Operations Command in Florida. The factory may travel, but the contracts — and the design authority — still sit at home.
