Key Industries

Primary Industries in Seattle

Seattle’s strongest manufacturing sectors — and the precision parts we machine for each.

Aerospace

Flight-critical precision parts

Seattle's aerospace ecosystem revolves around Boeing's Everett widebody assembly plant — the largest building in the world — producing 747, 767, 777, and 787 aircraft. Boeing's Renton facility builds the 737 MAX. Blue Origin develops orbital launch vehicles in nearby Kent, and hundreds of Tier 1 and Tier 2 suppliers machine aerostructures, engine components, and interior fittings across Puget Sound.

Defense

Mil-spec components & assemblies

Seattle's defense sector centers on Boeing's military aircraft division — P-8 Poseidon, KC-46 tanker, and advanced fighter programs all flow through Puget Sound facilities. Joint Base Lewis-McChord to the south and Naval Base Kitsap across the Sound drive steady demand for maintenance and depot-level machined parts.

Semiconductor

Wafer handling & chamber components

Seattle's semiconductor footprint extends beyond chip design at Amazon (Annapurna Labs) and Microsoft's custom silicon teams. Applied Materials and Lam Research maintain regional service operations, and local companies machine equipment components for fabs across the Pacific Rim.
