Micro Precision

What Micro Precision does

Micro Precision, LLC is a privately held, U.S.-based precision machining and mechanical assembly company founded in 1981 and headquartered in South Windham, Connecticut. Operating from a 20,000 square foot NAVSEA- and Level1/SUBSAFE-certified facility under a workforce of roughly 40 skilled machinists, technicians, and quality personnel, the company serves as a sole-source contractor for the U.S. Navy's Virginia- and Columbia-class nuclear submarine programs. It supplies critical components - hydraulic accumulators, valves, valve actuators, manifold assemblies, and weapons handling equipment - directly to Navy prime contractors and shipbuilders. The company is a subsidiary of Nautilus Integrated Solutions, a strategic operating company serving the U.S. Navy and nuclear industries.

The company's product and technology stack is centered on vertically integrated, in-house manufacturing. Capabilities include vertical CNC milling (up to 65 x 30 x 26 inches), horizontal CNC milling with pallet changers (up to 28 x 28 x 30 inches), CNC boring with a rotary table (59 x 47 x 55 inches), and CNC turning up to 80 x 30 inches. Quality assurance is built around CMM metrology, MIL-I-45208-aligned inspection systems, in-house hydraulic and hydrostatic test stands, and non-destructive testing (visual inspection and liquid penetrant testing). CAD/CAM programming supports prototype and production runs across aluminum, bronze, stainless steel, titanium, Monel, and plastics. Certifications include ISO 9001:2015 (held for 15 years), NAVSEA, Level1/SUBSAFE, and MIL-I-45208, supplemented by memberships in ACIBC, SIBC, and a NAVSUP partnership.

Revenue is generated through quote-based, project-specific contracts with U.S. Navy prime contractors and shipbuilders, with work delivered directly from the shop to shipyards and into submarines. Pricing is not publicly disclosed; the operating cadence aligns with multi-year naval program lifecycles. The go-to-market motion is enterprise field sales supported by a request-for-quote workflow, a LinkedIn corporate presence, and certifications as the primary credibility signal. The customer base is concentrated almost exclusively in U.S. Navy nuclear submarine and adjacent naval shipbuilding programs, with a secondary stated presence in homeland security applications.
