About this award

NASA Johnson Space Center awarded a $23.922 billion definitive contract to The Boeing Company for International Space Station sustainment and operations on November 15, 1993, under cost-plus-award-fee pricing, with ultimate completion targeted for September 30, 2031.

The contract reflects NASA's ongoing reliance on Boeing as the prime systems integrator for ISS habitat modules, payload operations, and lifecycle support across multiple decades. Place of performance is Houston, Texas 77058, with subordinate performance at ISS operational sites and payload partner locations worldwide.

Boeing's subcontractor team for ISS work is extensive and spans aerospace propulsion, systems integration, and component supply. Named subcontractors include Hamilton Sundstrand Corporation (Collins Aerospace) delivering hydraulic and propulsion systems components, Moog Inc. supplying electromechanical actuators and servo valves, Honeywell International (multiple divisions) providing avionics and precision aerospace components, and a multi-vendor team including Redwire Space Enterprises (propulsion and solar array systems), S & K Global Solutions (tribally owned, minority-owned small disadvantaged business providing spacecraft assembly support), and smaller specialty suppliers including Onyx Aerospace, Barrios Technology (woman-owned small business), Parker-Hannifin (hose and coupling assemblies), and Glenair (electrical connectors and wiring harnesses). CDW Government delivers IT hardware and software, while Ignite Fueling Innovation (service-disabled veteran-owned small business) and All Points Logistics (veteran-owned small business) provide systems engineering and logistics support. Language Exchange Translation Services and specialized support vendors including Geocontrol Systems (HUBZone small business) and Atec Inc. round out the team across non-production, engineering, and procurement domains.

The contract ceiling of $23.922 billion represents one of NASA's largest single-award vehicles, anchoring the agency's human spaceflight program through multiple Space Shuttle retirement, ISS assembly, and permanent operations phases spanning three decades.
