Boeing has decided to not submit a proposal to build up to 22 GPS III satellites for the U.S. Air Force. The GPS III Follow On (GPS IIIF) program will supply additional upgraded satellites to replace ones now in the constellation. “We have not put in a proposal for GPS III,” said Rico Attanasio, Boeing’s director of Department of Defense and civil navigation and communications programs, to Space News. Lockheed has been the only producer of GPS III satellites, and is now under contract to build the first 10. Boeing built earlier versions of GPS satellites. Lockheed Martin has submitted a proposal for the Follow On contract. In February, the U.S. Air Force Space Command (AFSC) released its request for proposals (RFP) to build the 22 GPS III satellites, called the GPS III Follow-On Phase 2 contract. The estimated dollar value of the acquisition is $10 billion including all options. Phase 2 is planned as a single, predominantly fixed-price incentive-type contract awarded via full and open competition for production of 22 GPS III satellites. Deadline for proposals is April 16. Construction is to begin in fiscal year 2019 (Oct. 1, 2018), with delivery of the first satellite in 2026. Boeing thought it could compete based on “innovation, resilience [and] a new payload, but that wasn’t emphasized,” Attanasio told Space News. “It wasn’t a good fit for us.”
