NAICS 336419: Other Guided Missile and Space Vehicle Parts and Auxiliary Equipment Manufacturing

NAICS 336419 – Other Guided Missile and Space Vehicle Parts and Auxiliary Equipment Manufacturing encompasses the design, development, and production of specialized components and subsystems that support guided missile systems and space vehicles, excluding complete missile or spacecraft assembly. This includes guidance and control units, propulsion subsystems, telemetry interfaces, thermal management systems, structural mounts, and other auxiliary equipment critical to mission-critical aerospace platforms. These components are often integrated into defense and space systems by prime contractors and must meet stringent military and aerospace standards such as MIL-STD and NASA-STD. The sector operates at the intersection of advanced materials science, precision machining, and avionics integration, serving as a vital enabler for national security and space exploration programs. STARWIN INDUSTRIES, LLC is the leading contractor in this NAICS code, recognized for its specialized manufacturing of high-reliability components used in missile defense and orbital systems. The competitive landscape is dominated by small to mid-sized defense subcontractors with deep expertise in niche aerospace systems, many holding AS9100 and ITAR certifications. These firms often operate under tiered supply chains, supporting prime contractors such as Lockheed Martin, Northrop Grumman, and Raytheon. The Department of Defense is the primary procuring agency, with demand driven by modernization initiatives in hypersonic weapons, missile defense architectures, and next-generation satellite constellations. Programs under the Missile Defense Agency, Space Force, and Army Aviation and Missile Command represent the core sources of procurement activity. The market is characterized by high technical barriers to entry, long qualification cycles, and a reliance on classified or controlled technical data. Opportunities exist for firms with proven capabilities in precision fabrication, radiation-hardened electronics, and rapid prototyping of flight-certified hardware. Contracting is increasingly focused on resilient supply chains and dual-use technologies that serve both defense and commercial space sectors.
