What the FY2027 request buys
Verbatim from the R-2A exhibit for project 67A021 of PE 1206423SF. 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 upgrades to modernize the AEP legacy ground control segment system to deliver OCX CDD requirements in place of OCX. Upgrades include GPS IIIF Launch, GPS IIIF C2, SAASM and NGA Receiver Integration. Additional upgrades to system interface tools are planned to support development and fielding of CNAV monitoring CDD requirements. 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 increases due to on-going AEP modernization efforts.
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.
Develop upgrades to modernize the AEP legacy ground control segment system to deliver OCX Capability Development Document (CDD) requirements in place of OCX. Upgrades include GPS IIIF Launch, GPS IIIF Command & Control (C2), Selective Availability Anti‐Spoofing Module (SAASM) and National Geospatial‐Intelligence Agency (NGA) Receiver Integration. Additional upgrades to system interface tools are planned to support development and fielding of Civil Navigation (CNAV) monitoring CDD requirements. 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) |
|---|---|---|
| FY2026 | Enacted | 72.5 |
| FY2027 | Request | 222.2 |
This activity is 100% of project 67A021's FY2027 request and 67% of PE 1206423SF'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.
