Space Force Adds $95M to GPS IIIF Contract to Settle Production Line Disruption

The U.S. Space Force has awarded Lockheed Martin a $95 million contract modification for the GPS III Follow-On program, raising the spacecraft production contract's cumulative value to $4.73 billion. The modification resolves production line impacts caused by prior federal budget deferrals, stabilizing manufacturing at the company's Littleton, Colorado facility.

The Department of Defense announced the modification, designated P00208, on Friday, Oct. 30, 2026. It fully funds an equitable adjustment tied to a year-long production hiatus known as a "Zero Buy," which resulted after the Department of the Air Force omitted new satellite orders from the fiscal year 2025 budget request.

The $95 million award settles a formal Request for Equitable Adjustment submitted after that budget omission. The payment covers overhead and parts continuity costs without adding new spacecraft hulls to the manifest. In June 2026, Space Systems Command awarded Lockheed Martin a $514 million contract for GPS IIIF space vehicles 23 and 24, expanding the total number of follow-on spacecraft under firm contract to 14. That procurement reinforced the primary constellation following congressional scrutiny over the service's decision to terminate the Resilient GPS program in favor of hardening heavy orbital assets.

The program operates under prime contract FA8807-18-C-0009, originally awarded in 2018 with options for up to 22 space vehicles. The GPS IIIF line introduces survivability enhancements over baseline GPS III platforms. It integrates Regional Military Protection, delivering a 63-fold increase in anti-jam resistance over legacy military code transmissions. Starting with vehicle SV13, satellites will integrate Lockheed Martin's LM2100 Combat Bus, featuring enhanced cyber defenses and hardened structural shielding. Each satellite also incorporates an upgraded search-and-rescue payload and a laser retroreflector array for high-precision orbit determination.

The modification stabilizes Lockheed Martin's manufacturing line in Littleton without expanding the current manifest, resolving the production impacts created by the year-long Zero Buy. The June 2026 award reinforced the core positioning, navigation, and timing constellation following congressional scrutiny of the Resilient GPS termination.

Lockheed Martin is scheduled to deliver the first GPS IIIF space vehicle, SV11, in 2027, transitioning the program from development to operational fielding under Space Systems Command's Military Communications and PNT Directorate. The Space Force retains eight unexercised production options under the master contract, with fiscal year 2027 budget deliberations set to determine procurement for SV25 and SV26.
