What the FY2027 request buys
Verbatim from the R-2A exhibit for project S0417 of PE 1160483BB. 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.
Continues extended table development. Finalizes testing of next collective propulsion device and acoustic communications devices. Continues testing of A/O communications devices and finalizes testing of next collective propulsion device. Begins development of Expeditionary Diver Treatment System and Submarine Lock Out Trunk trainer.
Increase of $12.088 million continues extended table development, testing of next collective propulsion device and acoustic communications devices, testing of A/O communications devices and next collective propulsion device. Begins development of Expeditionary Diver Treatment System and Submarine Lock Out Trunk trainer.
FY2025–FY2026: what came before
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.
Begin extended table development, both in depth and duration, testing and development of next generation diver navigation equipment, next generation propulsion devices, SO-p Lock In/Out (LIO) deep diving Underwater Breathing Apparatus, and continues development and integration of communications devices for both acoustic and optical. Note: FY 2026 President's Budget included $0.00 million in discretionary funding and $27.764 million in mandatory funding for CBDIV.
Continue development, prototyping and the advancement of Engineering Development Model (EDM), testing and rapid prototyping of new SO-p underwater mixed gas breathing apparatus and the development of associated diving procedures specific to SO-p capabilities. Development of emergency breathing systems and diving treatment systems supporting the SO-p diving deployment from USSOCOM maritime platforms, next generation diver propulsive equipment with integrated thermal protection increasing range and duration in the water, development of underwater communications networks of diver-to-diver communications, and optical and acoustic communication systems of a new mixed gas underwater breathing apparatus (UBA).
Three years, and no five-year plan
An R-2A activity publishes the prior year, the current year and the budget year. The FYDP outyears exist at project and program-element level and are deliberately absent here rather than inferred. Estimate types are colored and never summed into one figure.
| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2025 | Actual | 11.3 |
| FY2026 | Enacted | 0.0 |
| FY2027 | Request | 12.1 |
This activity is 4.2% of project S0417's FY2027 request and 3.4% of PE 1160483BB'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.
