The Navy just took a big step toward fighting smarter, not just harder. A containerized “factory‑in‑a‑box” from Firestorm Labs — called xCell — was carried aboard the Wasp‑class assault ship USS Essex and used to 3D print unmanned aerial systems and spare parts while underway during RIMPAC 2026. It’s a tidy bit of modern warfare: make parts where you fight, skip the long supply chain, and keep ships mission‑ready without sailing back to port.
What happened aboard USS Essex: 3D printing drones at sea
During the Rim of the Pacific exercise, the Navy and industry ran a theater‑wide experiment in expeditionary manufacturing. Firestorm’s xCell was one of several containerized systems operating on ships. Company briefings say xCell produced over 1,000 parts and multiple Squall FPV airframes while the Essex was underway. Rear Adm. Michael Mattis called the effort the largest advanced manufacturing event the fleet has held — and for good reason: the demo tied shipboard printers to autonomous delivery and networked logistics to test “point‑of‑need” production at sea.
Operational upside: shorter supply lines and affordable mass
This matters because contested logistics is a real problem. If supply lines are cut, a ship that can print spare parts and attritable drones could keep fighting. Firestorm’s CEO says xCell lets crews produce, sustain, and repair “at the point of need.” The Navy’s planners see this as a way to field low‑cost swarms and replace parts fast — a sound idea if you want to preserve tempo and pressure an adversary without begging for resupply convoys.
Practical limits and red flags: feedstock, quality, and rules
Don’t let the shiny demo fool you: printing is not a magic box. Raw polymer and metal feedstock still have mass and volume — you can’t fit infinite printers and never run out of plastic. Quality control at sea matters, too; waves, vibration, and salt air all affect part strength. Then there’s the policy side: who decides what gets printed, how firmware and cyber integrity are enforced, and whether modular platforms are restricted from becoming improvised weapons? We shouldn’t be cute about this — we need production logs, failure rates, and clear rules of engagement for printed systems.
Embrace the tech, but demand oversight
Innovation won’t wait, and we shouldn’t slow it down. With strong leadership from President Trump and War Secretary Pete Hegseth pushing a warrior ethos, the Navy is right to test tools that cut the tyranny of distance. But Congress, Navy leaders, and commanders must insist on hard metrics: verified production counts, QA results, feedstock math, and a secure supply‑chain plan. Scale the factories‑in‑a‑box, by all means — just don’t let a 3D printer on deck become an unaccountable black box. The future of sea power looks smarter; now make sure it’s also safe, sustainable, and under civilian control.
