What the FY2027 request buys
Verbatim from the R-2A exhibit for project 3389 of PE 0603564N. 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.
Research, development and testing of advanced refueling systems and concepts to include: completion of the iMFDS at sea demonstration; DP CONSOL investigation, concept design, and material procurement; and MCAK 2.0 initial concept designs and initial material procurement.
Increase of funding by $7.098 million due to two new R&D efforts: MCAK 2.0 spiral development and Double Probe (DP) CONSOL.
FY2026: the year under way
Prior-year accomplishments and current-year plans from the same exhibit. Context for the FY2027 plan, not a series — an activity partitions its project exactly in the request year, but can under-cover it in earlier years.
Research, development, and testing of advanced refueling systems and concepts to include: completion of the improved Modular Fuel Delivery Station (iMFDS) tanker version detailed design, material procurement and starting prototype fabrication
Three years, and no five-year plan
An R-2A activity publishes the prior year, the current year and the budget year. The FYDP outyears exist at project and program-element level and are deliberately absent here rather than inferred. Estimate types are colored and never summed into one figure.
| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2025 | Actual | 5.6 |
| FY2026 | Enacted | 7.2 |
| FY2027 | Request | 14.3 |
This activity is 66% of project 3389's FY2027 request and 2.1% of PE 0603564N'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.
