NAICS 336419

Overview

The North American Industry Classification System (NAICS) is the structure used by U.S. federal statistical agencies to classify business establishments for the collection, analysis, and publication of economic data. NAICS was developed under the Office of Management and Budget (OMB), first adopted in 1997 to replace SIC, and is jointly maintained by the U.S., Canada, and Mexico. The current statistical vintage in use is 2022, which governs official industry definitions, cross-references, and data reporting across agencies. ¹

NAICS 336419 covers establishments primarily engaged in manufacturing guided missile and space vehicle parts and auxiliary equipment other than propulsion units/parts, and in developing and making prototypes of those parts and auxiliary equipment. Work on complete guided missiles and space vehicles is classified in 336414, propulsion units and propulsion unit parts in 336415, and navigational and guidance systems in 334511. These boundaries are set by the official 2022 NAICS industry definition and cross-references. ²

What this NAICS covers

• Manufacturing non-propulsion parts for guided missiles and space vehicles (e.g., structures, control surfaces, housings). ²
• Fabrication of auxiliary equipment for guided missile and space vehicle systems (e.g., launch support, interfaces, fixtures), excluding propulsion. ²
• Developing and producing prototypes of the above parts and auxiliary equipment. ²
• Production aligned with system integration needs where the deliverable remains a part or auxiliary equipment rather than a complete vehicle or propulsion unit. ²

Key exclusions and cross-references

• Complete guided missiles and complete space vehicles are classified in 336414. ²
• Propulsion units and propulsion unit parts are classified in 336415. ²
• Navigational and guidance systems are classified in 334511. ²
• Research and development of guided missile/space vehicle parts and auxiliary equipment (except prototype production) are classified in NAICS research and development industries, not within 336419. ²

Frequently asked questions

• What activities define NAICS 336419?
  Establishments make guided missile and space vehicle parts and auxiliary equipment other than propulsion items and may develop and produce prototypes of those parts and equipment. This code does not include complete vehicles, propulsion units, or standalone navigation/guidance systems. ²

• How does 336419 differ from 336414 and 336415?
  336414 covers complete guided missiles/space vehicles; 336415 covers propulsion units and related parts. 336419 covers other parts and auxiliary equipment and related prototype production. ²

• Are navigation and guidance electronics included in 336419?
  No. Navigational, guidance, and related aeronautical/nautical systems and instruments are classified in NAICS 334511, not in 336419. ²

• Does 336419 include prototype work?
  Yes. Developing and making prototypes of guided missile and space vehicle parts and auxiliary equipment are covered, but broader R&D activities (except prototype production) fall under research and development industries, not 336419. ²

• Which PSCs commonly align with 336419 deliverables?
  Depending on the item, agencies often cite PSCs such as 1420 (Guided Missile Components), 1440 (Launchers, Guided Missile), 1675 (Space Vehicle Components), or 1735 (Space Vehicle Handling and Servicing Equipment). Use is contract‑specific. ³
