Renton Is Where Every 737 MAX Is Born
Renton is not a city with an aerospace program — Renton is the 737. The Boeing Renton Factory at 737 Logan Ave N (ZIP 98057) is the world's highest-rate commercial aircraft production site: three final-assembly lines running 38–42 aircraft per month in 2026, every one of them a 737 MAX -7, -8, or -10. Every 737 MAX airframe has approximately 400,000 individual parts. Every P-8 Poseidon maritime patrol aircraft for the US Navy, exported to 8+ allied nations under ITAR, also assembles from a Renton-derived structure. Exotic Metals Forming Company at 1625 E Valley Rd sits less than a mile from the factory gate, forming titanium and nickel superalloy pylon and nacelle parts. GKN Aerospace in Auburn (12 miles south) supplies 737 fuselage stringers and frames. Safran Landing Systems provides Ti-alloy trunnions. RivCut machines parts for this entire supply chain from Union City, CA, with Boeing D6-17487, D1-9000-1 AQS, and ITAR-registered P-8 handling built in.

D1-9000-1 AQS, D6-82479 approved-source language, D6-17487 narrow-body process spec, AS9102 FAIR packages, and ITAR-registered chain of custody for P-8 Poseidon defense programs. Our QMS is structured to drop into a Boeing 737 supplier-portal audit.
