What the FY2027 request buys
Verbatim from the R-2A exhibit for project 1265 of PE 0101226N. 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.
-MK5 DT/OT -Continue deliveries of MK5 LRIP units -Continue MK6 Prototype Development
The FY 2026 budget request for the Submarine Defensive Warfare Project 1265 includes $18,664K of discretionary and $8,700K of mandatory (reconciliation) for a total of $27,364K. This FY 2027 budget request represents a decrease of $6,985K from FY 2026 to FY 2027. This decrease is primarily driven by reduced development costs for the ADC MK5 program in FY 2027 and transitioning to DT and OT.
FY2026: the year under way
Prior-year accomplishments and current-year plans from the same exhibit. Context for the FY2027 plan, not a series — an activity partitions its project exactly in the request year, but can under-cover it in earlier years.
-ADC MK5 Production Readiness Review (PRR) -ADC MK5 HWIL (M&S) integration -Deliveries of ADC MK5 LRIP units -MK5 DT/OT -MK5 Iterative Development -MK6 Prototype Development
Three years, and no five-year plan
An R-2A activity publishes the prior year, the current year and the budget year. The FYDP outyears exist at project and program-element level and are deliberately absent here rather than inferred. Estimate types are colored and never summed into one figure.
| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2025 | Actual | 16.3 |
| FY2026 | Enacted | 18.7 |
| FY2027 | Request | 20.4 |
This activity is 100% of project 1265's FY2027 request and 18% of PE 0101226N'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.
