Firestorm Labs Proves On-Ship 3D Printing: Manufacturing Drone Parts at Sea
Additive Manufacturing Moves Aboard a Navy Warship
San Diego-based Firestorm Labs has demonstrated that additive manufacturing can produce mission-critical UAV components far from any factory floor, completing a two-week exercise in which the company 3D printed more than 1,000 components for its Squall UAVs and other equipment while underway aboard the USS Essex.
The trial answers a long-standing question for defense logistics: can a warship sustain its own small-drone fleet with parts printed on demand? Firestorm’s results suggest the answer is yes, and the implications reach well beyond the Navy.
Why At-Sea Manufacturing Matters
Military drone operations are constrained by the supply chain that feeds them. A broken propeller hub, a cracked housing, or a worn mounting bracket normally means waiting days or weeks for a replacement to reach a deployed unit. Printing those parts on the vessel that operates the drones collapses that timeline to hours.
The approach is especially relevant to smaller Group 1 and Group 2 UAS, whose airframes and payload mounts are increasingly built from engineered polymers and short-run composite structures rather than heavy metal tooling. These are exactly the part categories that fused-deposition and other polymer additive processes handle well.
What the Exercise Actually Produced
Across the deployment, Firestorm reports that its printers turned out more than a thousand individual components spanning the Squall platform and supporting equipment. The volume matters as much as the part count: it shows the process can keep pace with operational demand rather than serving as a one-off demonstration.
Equally important, the printed parts entered real use alongside conventionally manufactured inventory, a step that matters more than a laboratory benchmark. Operators gained confidence that a printed bracket or fairing performs to the same standard as its molded or machined counterpart.
The Broader Industrial Drone Angle
While the at-sea test is a defense story, the capability it proves is directly relevant to industrial and enterprise UAV programs. Remote mining sites, offshore energy platforms, and field survey crews all share the same pain: a grounded aircraft waiting on a spare part.
Distributed additive manufacturing, whether aboard a ship or in a field container, changes the economic calculation. A modest printer stock of certified filament can replace a shelf of pre-made spares, cutting inventory cost while improving uptime. For operators running large fleets of industrial drones, that is a meaningful margin shift.
What Comes Next
Firestorm’s demonstration is a proof point, not an endpoint. Scaling on-ship printing to broader fleet use will require certified material stocks, validated print recipes for each part, and quality-control procedures that hold up under maritime conditions, including humidity and motion.
Those are engineering challenges rather than fundamental obstacles. As the U.S. military and its allies push toward smaller, more expendable, and more distributed drone fleets, the ability to manufacture and repair at the point of need is becoming a capability requirement rather than a novelty.
For industrial drone operators watching from the commercial side, the lesson is the same one the Navy just learned: the factory is no longer the only place a drone part can come from.
