What the FY2027 request buys
Verbatim from the R-2A exhibit for project 653170 of PE 1203269SF. This is the budget justification's own description of work that has not happened yet — the one thing no other level of the budget carries.
Continue Development of GPS IIIF SV 11 and SV12. Continue development and initiate launch vehicle assembly of GPS IIIF SV12. Finalize the build, qualification, and delivery of GSS+ which will be utilized for Mission Readiness testing, Integrated Cyber Testing, System Integration Demo 31, and Space Vehicle risk reduction events and provide critical capabilities for on- orbit checkout testing (OOCT) and anomaly resolution for the GPS IIIF constellation. As part of overall GPS IIIF advanced capabilities development, continue developing the Enhanced Command & Control/Modular Open System Approach capability through continued special studies and reviews, continue development toward a GPS IIIF optical crosslinks demonstration (as a follow-on to the GPS III SV10 crosslinks demonstration), and continue development of the On-Orbit Reprogramming capability. GPS IIIF will continue special studies targeted to mitigate on-ramp capability risks. Rapidly respond to implement system resiliency and situational awareness necessary to operate in the contested space domain. Activities may include, but are not limited to program office support, studies, technical analysis, experimentation, risk reduction, prototyping, and activities that may leverage commercial, U.S. Government partnership, and international opportunities to respond to existing and emerging adversarial threats with speed and agility.
FY 2027 Funding decreased due to the delivery of risk-reducing simulators (GSS+) and reduction in costs in late-stage development of SVs 11 and 12.
FY2026: the year under way
Prior-year accomplishments and current-year plans from the same exhibit. Context for the FY2027 plan, not a series — an activity partitions its project exactly in the request year, but can under-cover it in earlier years.
Continue Development of GPS IIIF SV 11 and SV12. Continue development and initiate launch vehicle assembly of GPS IIIF SV12. Continue the build, qualification, and delivery of GSS+ which will be utilized for Mission Readiness testing, Integrated Cyber Testing, System Integration Demo 31, and Space Vehicle risk reduction events and provide critical capabilities for on-orbit checkout testing (OOCT) and anomaly resolution for the GPS IIIF constellation. As part of overall GPS IIIF advanced capabilities development, continue developing the Enhanced Command & Control/Modular Open System Approach capability through Implementation Design Review 1 (IDR.1)/Preliminary Design Review, continue development toward a GPS IIIF optical crosslinks demonstration (as a follow-on to the GPS III SV10 crosslinks demonstration), continue the On-Orbit Reprogramming capability through IDR.1. GPS IIIF crosslinks IDR will focus on risks, interoperability to the larger architecture, and incorporating/validating commercial/driving modernization of capabilities. GPS IIIF will continue special studies targeted to mitigate on-ramp capability risks. Rapidly respond to implement system resiliency and situational awareness necessary to operate in the contested space domain. Activities may include, but are not limited to program office support, studies, technical analysis, experimentation, risk reduction, prototyping, and activities that may leverage commercial, U.S. Government partnership, and international opportunities to respond to existing and emerging adversarial threats with speed and agility.
Three years, and no five-year plan
An R-2A activity publishes the prior year, the current year and the budget year. The FYDP outyears exist at project and program-element level and are deliberately absent here rather than inferred. Estimate types are colored and never summed into one figure.
| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2025 | Actual | 171.2 |
| FY2026 | Enacted | 89.6 |
| FY2027 | Request | 59.3 |
This activity is 100% of project 653170's FY2027 request and 48% of PE 1203269SF's. In the request year the activities under a project sum to it exactly; in the current year they under-cover it in about 9% of cases, so an activity's delta can legitimately exceed its parent's and the two must not be compared row to row.
