In a bold strategic move, the U.S. Navy, in partnership with ASTRO America, is launching a $40 million advanced 3D printing facility on Guam. Named the Guam Additive Materials & Manufacturing Accelerator (GAMMA), the project promises to shrink naval repair times from months—sometimes years—to just weeks. It’s a game-changer not just for military readiness, but for economic development, education, and innovation in the Indo-Pacific.

Guam’s Strategic Role in U.S. Naval Operations
Guam sits roughly 6,000 miles from the U.S. mainland, yet it’s a cornerstone of American power in Asia, home to five nuclear-powered fast-attack submarines at Polaris Point. Until now, essential parts often took 6 months to 2 years to arrive from stateside, hamstrung by logistics and supply chain delays. That’s changing fast with GAMMA’s on-demand manufacturing.

The GAMMA Project: A $40 Million Strategic Push
ASTRO America leads the initiative, with a $5 million initial Navy contract already awarded, and an additional $12 million expected soon, supplemented by BlueForge Alliance and the Navy’s Maritime Industrial Base Program Office.
The $40M facility is slated to be fully operational by April 2026, with temporary training spaces opening as early as late 2025. The permanent facility will span 8,000 square feet, featuring a manufacturing lab, classrooms, offices, and a conference space.
Guam’s Governor Lou Leon Guerrero sees GAMMA as a double win: “This means economic improvement, more jobs for our people, more training for our people… beyond the military into the broader civilian community.”
From Years to Weeks: A Maintenance Revolution
Broken components—like a submarine valve—traditionally required long lead times to manufacture and ship. GAMMA promises a dramatic turnaround: from 2 years to just 2 weeks. This firm’s director, Alex Benham, says the time savings are enormous, and the cost savings astronomical.
This acceleration not only improves fleet readiness but also lightens the load on Guam’s submarine tenders, which can then focus on repairs best suited to their capabilities.
Cutting-Edge 3D Printing Capabilities
GAMMA will house:
- Polymer 3D printers for smaller plastic parts.
- Directed Energy Deposition (DED) machines for large metal components.
- Laser Powder Bed Fusion (LPBF) systems for intricate metal parts.
All printed parts will undergo on-site inspection and quality assurance, meeting naval standards in-house. The facility will even be able to print its own tools and replacement components, a self-sufficiency advantage in Guam’s isolated environment. Over time, the techniques proven here could extend into aerospace, automotive, and construction industries.

Workforce Development and Economic Impact
With no local mechanical engineering programs, GAMMA aims to fill that gap through partnerships with the University of Guam, Guam Community College, and potentially a mainland U.S. university satellite campus. The project is expected to create 85–100 local jobs, offering career paths in advanced manufacturing and supporting Guam’s economic diversification.
A Broader Naval Strategy: “Point-of-Need” Manufacturing
GAMMA supports the Navy’s larger shift toward distributed, on-demand production—manufacturing components at the point of need rather than transporting them across the globe. It complements other Department of Defense additive manufacturing projects.
Looking Ahead: Guam as an Innovation Hub
By spring 2026, GAMMA could transform naval logistics in the Pacific—making once-lengthy repair times routine. It’s poised to serve as a model of dual military and civilian benefit, potentially expanding beyond defense to support aerospace, construction, and other industries. Guam might soon be known not for its delays, but as a rapid-response manufacturing powerhouse.
