RIMPAC 2026 Signals New Era In Deployable 3D Additive Printing In Contested Zones

SYDNEY - EntSun -- LCC Asia Pacific®, the Sydney-headquartered corporate finance and strategy advisory firm, today released RIMPAC 2026: Additive Manufacturing in the Contested Zone, an executive briefing examining how forward-deployed manufacturing is reshaping military logistics, combat generation and the mission life of defence assets across the Indo-Pacific.

The briefing draws on the 2026 Rim of the Pacific exercise, where a distributed advanced-manufacturing network of more than 50 nodes operated across warships, forward bases and autonomous logistics links. Aboard USS Essex, more than 1,000 parts and 12 complete FPV drones were manufactured at sea and subsequently flown in counter-UAS experimentation. Metal components were produced in conditions up to Sea State 5, and digitally crewed surface vessels delivered manufactured parts to joint forces in under 24 hours.

"RIMPAC 2026 demonstrated something far more consequential than 3D printers working at sea. It showed that manufacturing itself can become a deployable military capability — and that the strategic shift is from a fixed inventory to a partially regenerable combat load."  —  Nicholas Assef, Founder & Managing Director, LCC Asia Pacific

The paper argues that this convergence of additive manufacturing, autonomous systems and digital inventory arrives at a decisive moment for Australia, as the nation extends the Collins-class fleet, builds AUKUS submarine sustainment capability and prepares for increasingly contested regional logistics.

"For Australia, the opportunity is not simply to buy more printers," Nicholas Assef said. "It is to build an interoperable AUKUS manufacturing environment — qualified materials, secure technical data and multiple sovereign production nodes — so that a low-cost bracket or valve body never again determines whether a ship or submarine can sail. That is sovereign industrial capability, and it is also a significant opportunity for Australian technology companies with export potential."

Key findings

• The relevant capability is distributed manufacturing, not the standalone printer.
• Forward additive manufacturing can contribute to combat generation as well as sustainment — a vessel becomes a limited producer of combat mass.
• Inventory can shift from finished spares toward qualified feedstock and digital designs.
• Digital qualification of legacy parts can extend the mission life of ageing platforms through the AUKUS transition.
• For smaller maritime nations, dispersed manufacturing offers an asymmetric strategy — making a limited force far harder to exhaust.
