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 applied research related to critical Science and Technology (S&T) for Rapid-Reaction Undersea Weapons and Counter-Measures, High-Speed Vehicle Technology, Undersea Warheads Technology, RPG-of-the-Sea and Air-Independent Power and Energy. - Continue applied research to explore additional transition opportunities for technologies developed under the High-Speed Vehicle Technology. - Continue expanding efforts associated with sensing and warhead testing. - Continue basic and applied research in directed energy for undersea applications, and undersea effects for deep sea and seabed warfare. - Continue sensing, target updating, and propulsion technologies for long endurance weapons. - Continue applied research in coordinated networks of weapons and sensors and new weapons concepts. -Initiate applied science for seabed warfare technologies. - Initiate investigation of free-space and fiber contained optical transport solutions and associated technology developments - Initiate measurement and model propagation in highly dynamic environment to enable performance prediction in support of validation of atmospheric prediction models - Initiate investigation of novel window materials and anti-reflection approaches and environmental impacts - Initiate exploration of novel enclosure materials to meet performance while addressing environmental and operational exposure
Funding decrease from FY2026 to FY2027 is due to reduced development across multiple Undersea Weaponry projects, including applied science for seabed warfare technologies.
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.
- Continue applied research related to critical Science and Technology (S&T) for Rapid-Reaction Undersea Weapons and Counter-Measures, High-Speed Vehicle Technology, Undersea Warheads Technology, RPG-of-the-Sea and Air-Independent Power and Energy. - Continue applied research to explore additional transition opportunities for technologies developed under the High-Speed Vehicle Technology. - Continue expanding efforts associated with sensing and warhead testing. - Complete related field activities under the Torpedo Field/Lab Experimentation Program. - Initiate basic and applied research in directed energy for undersea applications, and undersea effects for deep sea and seabed warfare. - Initiate sensing, target updating, and propulsion technologies for long endurance weapons. - Initiate applied research in coordinated networks of weapons and sensors and new weapons concepts.
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 | 14.4 |
| FY2026 | Enacted | 13.7 |
| FY2027 | Request | 10.9 |
This activity is 21% of project 0000's FY2027 request and 21% 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.
