Guam Additive Manufacturing hub to cut Navy repair times
The US Navy, through the Guam Additive Materials and Manufacturing Accelerator (GAMMA), led by the Applied Science and Technology Research Organization of America (ASTRO America), is building a new Additive Manufacturing hub on Guam to reduce repair timelines for deployed vessels.
The $40 million facility is intended to produce critical ship and submarine components locally rather than relying on long supply chains from the mainland. In a recent update, officials estimated that turnaround time could be reduced to as little as two weeks, reportedly a potential reduction of up to 98%.
Located in Dededo, Guam, the 8,000-square-foot site will house polymer AM machines, Directed Energy Deposition machines, and Laser Beam Powder Bed Fusion (PBF-LB) machines to cover a wide range of naval needs.
Beyond faster repairs, GAMMA supports the Navy’s broader shift toward distributed, point-of-need manufacturing in the Indo-Pacific. If successful, the model could strengthen fleet readiness, reduce logistics risk, and help build a regional advanced manufacturing workforce ahead of its planned 2026 operational launch.
