Granite State Manufacturing

Granite State Manufacturing is a key supplier of mission-critical systems to the US Navy.

Every member of our team of welders, machinists, assemblers, engineers & business staff, plays a vital role in supporting our country’s men & women in uniform. Their mission is our mission.

In support of this mission, GSM is growing at the most rapid pace in our company’s 85+-year history.

Our major customers, the United States’ two largest shipbuilders, depend on GSM & our manufacturing know-how to supply complex, life-critical systems and solutions, as they design & build the US Navy’s fleet of warships & nuclear-powered submarines.

GSM is proud of our crucial role at this pivotal moment in history.
