CONSTELLATION MACHINING LLC

Constellation Machining LLC specializes in precision machining and fabrication of mission-critical components for defense systems, with deep expertise in high-tolerance metalworking for ammunition, missile, and ordnance applications. The company produces complex hardware including cartridge cases, firing plugs, shear pins, heat shields, nozzle cups, and sabots using advanced CNC machining and secondary finishing processes. Their technical capabilities extend to working with hardened alloys and proprietary military-grade materials under tight dimensional tolerances, ensuring reliability in extreme operational environments. Specialization in small-batch, high-precision production for sensitive defense platforms distinguishes them as a trusted supplier for components requiring strict adherence to military specifications and traceability standards. The contractor maintains a consistent and exclusive relationship with the Department of Defense, delivering precision-machined parts across multiple branches and defense logistics centers, including direct support to the Letterkenny Munitions Command. Their work supports ground ordnance systems, guided missile assemblies, and propulsion components, indicating close collaboration with defense materiel developers and production facilities focused on munitions lifecycle management. Industry focus centers on NAICS 332710 (Machine Shops), where they deliver custom machining services for defense hardware, supplemented by expertise in hardware manufacturing (332510) and specialized components for guided missile and space vehicle systems (336419). This positions them as a niche supplier within the defense industrial base, serving the ordnance and aerospace propulsion sectors with precision-engineered, low-volume, high-reliability parts. Constellation Machining LLC is a small business based in Mechanicsville, Maryland, operating as a privately held entity without federal certifications. Their geographic proximity to key defense manufacturing corridors enhances responsiveness to DoD logistics networks, supporting just-in-time delivery for critical defense programs.
