AML3D wins first US Navy submarine production order from Austal USA

Order from Austal USA for submarine components

AML3D Limited (ASX:AL3) announced on September 17, 2026 that it had secured an initial production parts order from Austal USA valued at approximately A$0.5 million, covering three large, high-pressure Copper-Nickel fluid control components for US Navy nuclear submarines. The contract moves production of those parts from traditional manufacturing methods to AML3D's proprietary Wire-Arc Additive Manufacturing (WAM) process, converting a previously completed CuNi qualification program into commercial production.

Production terms and timeline

The company said the parts would be metal 3D printed at its US headquarters and technology center in Stow, Ohio, with completion targeted by the end of the third quarter of FY27. Payment terms were structured as 50% of the contract value upfront and the remaining balance on delivery, testing and commissioning, giving AML3D near-term cash flow while tying the remainder to validated output. AML3D framed component manufacturing alongside ARCEMY advanced manufacturing system sales as the two initial drivers of its US scale-up strategy in support of the US Navy submarine industrial base.

ARCEMY deployment and Navy industrial-base outlook

According to the company's September 17 disclosure, AML3D has deployed 17 ARCEMY systems to meet US demand to date, 16 of which are in direct support of the US Navy submarine industrial base. The same statement referenced prior US Navy forecasts pointing to a need for up to 100 advanced additive manufacturing systems and 1,600 additively manufactured components by 2030, underscoring the scale of the addressable pipeline behind the new order.

Strategic framing inside FY2026 reporting

Reporting on AML3D's FY2026 results on the same day, Kalkine positioned the Austal USA order as evidence that component-manufacturing demand was beginning to complement the ARCEMY systems business, rather than replace it, within the company's US defense strategy. The framing tied the production contract to AML3D's broader industrial path in supplying the US Navy submarine program, while leaving open whether further production parts orders would follow the initial A$0.5 million award.
