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 development and systems engineering activities for the fabrication and integration of IBCS/ADAM prototypes at the A/B interface. Efforts include hardware and software design, updates to interface control documentation, interoperability and data exchange testing, and end-to-end system validation to ensure seamless communications and operational synchronization between IBCS and ADAM. Activities will culminate in prototype build completion, laboratory testing, and field integration events in preparation for follow-on developmental and operational testing.
FY 2027 funding was increased to support RDTE design and prototyping efforts on various platforms integrating AMDPCS and IBCS Increment 2 into IBCS Increment 3.
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 the development and systems engineering efforts for prototype builds and testing for IBCS and Air Defense and Airspace Management (ADAM) integration at the A/B interface.
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 | 11.0 |
| FY2027 | Request | 71.8 |
This activity is 82% of project S40's FY2027 request and 57% 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.
