What the FY2027 request buys
Verbatim from the R-2A exhibit for project 673109 of PE 1203109SF. 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.
Complete baseline systems engineering, system optimization, cybersecurity updates, and EMI mitigation efforts to ensure capacity is available to the end user, including the development and fielding of EMI mitigation solutions and inclination control and eclipse contingency studies for the space segment. Complete baseline E2E MUOS usability enhancements including terminal certification, integration, and test. Complete development of alternative IBS solution to mitigate Legacy UHF communications shortfalls and integration and interoperability efforts with other DoW and commercial systems and prepare for fielding.
FY 2027 decreased as ground segment updates will be replaced and modernized under the MUOS Service Life Extension activity.
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 systems engineering, system optimization, cybersecurity updates, and electromagnetic interference (EMI) mitigation efforts to ensure capacity is available to the end user, including the development and fielding of EMI mitigation solutions and inclination control and eclipse contingency studies for the space segment. Continue E2E MUOS usability enhancements including terminal certification, integration, and test. Continue development of alternative IBS solution to mitigate Legacy UHF communications shortfalls and integration and interoperability efforts with other DoW and commercial systems. Field Digital Earth Terminal Interface (D-ETI) at remaining RAFs.
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 | 21.7 |
| FY2026 | Enacted | 26.7 |
| FY2027 | Request | 20.6 |
This activity is 2.4% of project 673109's FY2027 request and 2.4% of PE 1203109SF'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.

Every R-2A line of this project, largest FY2027 request first. Linked where the activity has enough of its own narrative to carry a page; the rest are shown in full on the program-element page.
