What the FY2027 request buys
Verbatim from the R-2A exhibit for project 0000 of PE 0602747N. 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.
-Continue Active Sonar development of advanced signal and information processing for high duty cycle active sonar. Further development of concepts for next-generation active sonar system automation, leveraging the latest advances in machine learning and artificial intelligence. -Continue non-acoustic, orthogonal concepts that complement and augment active sonar concepts. -Continue Sensors applied research in improved sensor technology to include both passive and active acoustic and optical sensing to extend the capabilities of platform-based systems as well as innovative sensor technology for off-board and rapidly deployable systems. -Continue Signal Processing development of advanced signal and information processing for high duty cycle active sonar. -Continue development of technologies and techniques for exploiting structural acoustic vulnerabilities of adversary undersea platforms conducting an at sea trial. -Continue efforts that will lead to optimized sensing and behaviors by adapting in dynamic and uncertain environments; cooperative vehicle autonomy with increased endurance; data exfiltration and networking to expand reach; next generation sensors (acoustic and non-acoustic); adaptive, autonomous technologies to detect, classify, and track underwater mobile threats. -Continue development of technologies and signal processing, verified through sea trials that exploit the structural acoustics of undersea vehicles and structures.
Decrease in funding from FY2026 to FY2027 is due to decreased research efforts across multiple areas including active sonar development, sensor applied research, and signal processing development.
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.

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 | 11.8 |
| FY2026 | Enacted | 23.5 |
| FY2027 | Request | 18.8 |
This activity is 36% of project 0000's FY2027 request and 36% of PE 0602747N'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.
