AML3D Secures $9.9M ARCEMY X Order From HII for U.S. Navy Shipbuilding

Why It Matters

The contract signals a decisive shift toward wire‑based additive manufacturing in naval production, promising faster shipbuilding cycles and lower costs for the defense sector.

Key Takeaways

• $6.5M order adds four ARCEMY X printers to NNS.
• Total ARCEMY X fleet at Newport News reaches six units.
• WAM process cuts metal waste and lead times.
• Systems to be operational by Q3 FY2027.
• AML3D expands U.S. footprint via Ohio technology centre.

Pulse Analysis

The U.S. Navy’s push to modernize its production lines has found a new ally in large‑scale metal additive manufacturing. AML3D Limited, an Australian pioneer of wire‑based deposition, landed a roughly AU$9.9 million (about $6.5 million) contract with Huntington Ingalls Industries to deliver four ARCEMY X printers to Newport News Shipbuilding. The deal, announced in March 2026, marks the company’s most significant U.S. defense sale to date and underscores the growing confidence of American shipbuilders in overseas AM innovators. By situating the machines in AML3D’s Ohio technology centre, the firm shortens logistics and aligns with domestic content requirements.

The ARCEMY X platform leverages AML3D’s proprietary Wire Additive Manufacturing (WAM) process, which feeds metal wire into a high‑energy welding head to build parts layer by layer. Compared with powder‑bed systems, wire feed delivers higher deposition rates, lower material costs and eliminates the need for expensive powder handling and recycling. For naval applications—where components can exceed several meters and weigh multiple tonnes—these attributes translate into shorter lead times, reduced scrap, and the ability to produce replacement parts on‑demand. Integrated sensor suites and AI‑driven process monitoring further boost repeatability, allowing the printers to fit seamlessly into Industry 4.0 shop‑floor networks.

The contract expands Newport News’s ARCEMY X fleet to six units, positioning the shipyard to prototype and produce critical hull sections, propulsion brackets, and structural reinforcements in‑house. This capability not only trims the traditional casting‑machining cycle but also strengthens supply‑chain resilience by limiting reliance on external foundries. For AML3D, the order validates its U.S. expansion strategy and opens doors to additional defense programs seeking rapid, cost‑effective metal fabrication. As the Department of Defense continues to prioritize additive manufacturing for readiness, similar large‑scale wire‑based deployments are likely to accelerate across other military platforms.
