Originally planned to launch on a Falcon Heavy, GPS IIIF-1 was shifted to Vulcan when GPS III SV08, intended to launch on Vulcan, was moved to the Falcon 9 in 2025.
GPS IIIF (Global Positioning System) is the second evolution stage of the third generation of GPS satellites. The U.S. Air Force announced in September 2018 that a team led by Lockheed Martin won the competition to build the next-generation Global Positioning System (Navstar) Space System program, known as GPS IIIF. The satellites will be based on Lockheed Martin's LM2100M bus. These satellites are redesigned to be serviceable in orbit so they can be upgraded with new hardware.
