Big machines. Bigger stakes.
Precision machining and large-format welding — Manchester and Nashua, NH.
THIS IS NOT YOUR TYPICAL MACHINE SHOP
Every part we make goes into a submarine.
We machine and weld complex components for Virginia- and Columbia-class submarines — parts as large as 30-foot structural assemblies that require 30-ton cranes to move.
The work demands deep material knowledge, five-axis capability, and the kind of problem-solving that only comes with real experience.
Features on multiple discrete parts must be machined, positioned, and welded to within a few thousandths of an inch of each other.
EVERY. SINGLE. TIME.
