Granite State Manufacturing Insights
What We Do
Granite State Manufacturing (GSM) is a New Hampshire-based precision manufacturer with more than 85 years of history and a clear purpose: building complex systems that support the U.S. Navy submarine fleet. From our facilities in Manchester and Nashua, NH, our 170+-person team produces precision-machined components, certified weldments, electromechanical assemblies, and integrated systems for U.S. Navy programs, including submarine life support, sonar, & communications systems. We hold AS9100D, ISO 9001:2015, and ITAR registrations — and we take those standards seriously, because the people who use what we build depend on them. GSM is a growing company. We've received Navy Supplier Development Funding across four programs, invested in advanced 5-axis machining, large-scale welding, and high-bay assembly capability, and helped build active training partnerships with Nashua Community College, Manchester Community College, and UMass Lowell — with machining and welding programs funded in full by the U.S. Navy. Machinists, welders, quality professionals, engineers, planners, and program managers are some of the roles we hire for. People who do their best work when the stakes are real. If that sounds like you, we'd like to talk.
Why Work With Us
We machine, weld, and assemble systems for U.S. Navy submarines. Not generic contract work — specific, high-consequence builds that have to be right. Family-owned for 85+ years. Two NH facilities. Work worth being good at.
