What the FY2027 request buys
Verbatim from the R-2A exhibit for project 0000 of PE 0602271N. 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.
Navigation Technology: - Continue development on next generation atomic clocks to improve long-term stability and precision. - Continue development of earth magnetic anomaly maps for improved magnetic navigation. - Continue development of magnetic anomaly-aided navigation systems. - Continue development of celestial navigation and progress the development of onboard ephemeris. - Complete development of optical time transfer. - Complete development of modeling and simulation of PNT threats in the Live Virtual Constructive simulation. - Initiate development of navigating unmanned aerial system with cellular.
The funding decrease from FY 2026 to FY 2027 reflects reduced investments in Navigation Technology Applied Research to meet higher priority Navy requirements.
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.

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 | 14.2 |
| FY2026 | Enacted | 12.8 |
| FY2027 | Request | 11.0 |
This activity is 15% of project 0000's FY2027 request and 15% of PE 0602271N'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 project page.
