What the FY2027 request buys
Verbatim from the R-2A exhibit for project S40 of PE 0605457A. 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.
Funding in FY 2027 will support hardware upgrade development to include upgrades for Major End Items (MEIs), prototypes for emerging new requirements to further mature and validate planned hardware upgrades, and continuing evaluation of MEI upgrades.
FY 2027 IBCS Hardware Upgrades funding decreases from FY26 as the hardware baseline stabilizes to support Increment 2 Configuration.
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.
Funding in FY 2026 will support hardware upgrades to include support of System of Systems engineering and upgrades for Major End Items (MEIs) and system fielding, prototypes for emerging new requirements to further mature and validate planned hardware upgrades, and continuing evaluation of MEI upgrades.
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 | 18.6 |
| FY2027 | Request | 15.8 |
This activity is 18% of project S40's FY2027 request and 12% of PE 0605457A'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.
