This activity requests $110.1M in FY2027, 100% of project 67A023, up 58% on FY2026. The R-2A exhibit describes it across FY2026–FY2027, including what the FY2027 money is planned to buy.

What the FY2027 request buys

Verbatim from the R-2A exhibit for project 67A023 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.

FY2027 planned work

Complete software development to enable Global PNT C2 and continue software development for RMP checkout and Rapid Warfighter Effects (RWE) initial operations. Continue integration activities that support the validation of requirements with use of the OCX 3F GPS System Simulator. Deploy GPS IIIF Launch and Checkout System hardware. Prepare and continue coordination for System Integration Testing (SIT) of OCX 3F launch capabilities into the Operationally Accepted (OA) OCX baseline. Continue to support early GPS Enterprise integration testing in support of Mission Readiness Campaign (MRC) for GPS IIIF to include early development and testing specific to the evolved bus. Continue to incorporate Enterprise Mission Planning Systems capability into OCX 3F baseline. The Enterprise Mission Planning Systems enable Over the Air Rekey capability and other navigation warfare effects taskings. Additionally, initiate OCX 3F development for launching SV-13 Extended Bus (eBus) to the ground C2 systems for Launch and Checkout and PNT capabilities. 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.

FY2026 to FY2027 change

FY 2027 funding increases due to software development phasing adjustments to include development of evolved Bus updates to OCX 3F baseline.

Before the request year

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.

FY2026 plans — current year

Continue software development to enable Global PNT C2, RMP checkout and RWE initial operations. Continue integration activities that support the validation of requirements with use of the OCX 3F GPS System Simulator. Continue functional and physical control audits for delivery of OCX 3F baseline. Prepare and begin coordination for System Integration Testing (SIT) of OCX 3F launch capabilities into the Operationally Accepted (OA) OCX baseline. Continue to support early GPS Enterprise integration testing in support of MRC for GPS IIIF to include early development and testing specific to the evolved bus. Continue to incorporate Enterprise Mission Planning Systems capability into OCX 3F baseline. Continue development of Cadre Training and Technical Orders. The Enterprise Mission Planning Systems enable Over the Air Rekey capability and other navigation warfare effects taskings. 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.

Money

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.

This activity is 100% of project 67A023's FY2027 request and 33% 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.
