GPS IIIF: Space Force Pays $95M for Skipped Satellite Buy
The Space Force paid Lockheed Martin $95 million to settle costs from its paused GPS IIIF satellite purchase, money that buys no new hardware.
The U.S. Space Force has put a price on a year it chose not to buy GPS satellites: $95 million. In its contract announcements for 30 October, the Pentagon said Lockheed Martin of Littleton, Colorado, received a $95,000,000 modification (P00208) to contract FA8807-18-C-0009 “for fully funding the Zero Buy request for equitable adjustment.” A request for equitable adjustment is the formal claim a contractor files to recover costs caused by a government change to the terms of its work.
The modification raises the contract’s cumulative face value from $4,633,023,341 to $4,728,023,341. The full $95 million comes from fiscal 2025 and 2026 procurement funds and was obligated at award. Work is listed at Littleton and was due to be completed by 27 October 2026, three days before the announcement. The contracting office is the Space Force Portfolio Acquisition Executive for Satellite Communications and Positioning, Navigation, and Timing at Los Angeles Air Force Base. The announcement does not break down what the money covers, and neither the Space Force nor Lockheed Martin has published that detail.
How a skipped year became a bill
Contract FA8807-18-C-0009 is the GPS III Follow-On (GPS IIIF) production deal signed in 2018. According to the draft fiscal 2026 spending bill quoted by Breaking Defense in January, it covers up to 22 satellites and “includes pre-priced production options to leverage economies of scale, significantly reducing unit costs when buying more than one spacecraft in a year.”
The Department of the Air Force’s fiscal 2026 budget request put off the next scheduled satellite purchase. House and Senate appropriators objected, writing that the resulting “gap year” was “triggering a costly penalty payment” to the detriment of taxpayers, and that they “do not seek to encourage such fiscally imprudent decisions in the future.” They added $528 million for two satellites, raising the program’s procurement request from $110 million to $638 million, and told Air Force Secretary Troy Meink to prioritize GPS IIIF in the fiscal 2027 request rather than use it “to pay for other projects.”
The Space Force then exercised a fifth contract option worth $514.4 million for Space Vehicles 23 and 24, Space Systems Command said on 16 June. That brought the number of GPS IIIF satellites on contract to 14. The 30 October payment settles the cost of the gap in the production schedule that the budget request had created. The trade outlet Defense WarRoom, which reported on the payment, calculated that the $95 million equals about 37% of the cost of one satellite at the June price.
What GPS IIIF adds
GPS IIIF is the next block after the 10 GPS III satellites now in orbit; Lockheed Martin said the last of those, SV10, launched on 21 April 2026. The follow-on satellites are numbered SV11 through SV24. In its 15 June release, Lockheed listed three headline features: a Regional Military Protection capability that it says provides a 63-fold increase in anti-jam capability, more satellites broadcasting the encrypted military M-Code signal, and a fully digital navigation payload. Starting with SV13, the satellites move to Lockheed’s LM2100 Combat Bus, which the company says adds cyber hardening and more power, propulsion and room for later upgrades.
The satellites also carry civilian missions. The appropriators’ language cited improved search-and-rescue capabilities and improvements to the nuclear detection payload, and Lockheed says the new satellites broadcast all civil signals, including L1C and L5. Breaking Defense reported in January that Lockheed was scheduled to begin delivering the first IIIF satellite, SV11, in 2027.

Why it matters
Analysis, based on the sources cited in this article:
Anti-jam capability is the main selling point Lockheed and Space Systems Command cite for GPS IIIF, and the satellites are the Space Force’s main path to a more jam-resistant constellation. The zero-buy episode shows a budget trade-off that rarely shows up so plainly in contract notices: under a contract with pre-priced annual lots, skipping a year did not avoid spending. Part of the money went to a settlement that buys no hardware.
It also left fewer backup options. The Space Force ended its Resilient GPS effort, a plan for roughly 20 smaller satellites at $50 million to $80 million each, on 19 January 2026 after leaving it out of the fiscal 2026 request, according to SatNews. Congress responded with $15 million to keep resilient GPS space systems development going and $15 million for a commercial navigation demonstration, Breaking Defense reported.
The money also comes from the same space budget that funds other recent programs, from the Wideband Global SATCOM sustainment deal to geosynchronous reconnaissance prototypes and the Space Force’s satellite communications jammers. How the service balances older lines like GPS against new projects is a recurring question in Congress.
What to watch: whether fiscal 2027 appropriations fund the two GPS IIIF satellites in the request (Defense WarRoom puts that request at nearly $680 million); delivery of SV11 in 2027; how many of the eight remaining options the Space Force exercises; and whether any other contract in the program sees a similar adjustment.
