### Project 0000 — Undersea Warfare Applied Res

This PE funds applied research efforts in undersea target detection, classification, localization, tracking, and neutralization. Associated efforts focus on new Anti-Submarine Warfare (ASW) operational concepts that promise to improve wide-area surveillance, detection, localization, tracking, and attack capabilities against quiet adversary submarines operating in noisy and cluttered shallow water environments. Related efforts are aimed at leveraging technologies that will protect the country's current capital investment in surveillance, submarine, surface ship, and air ASW assets.

| Activity (R-2A) | FY2025 | FY2026 | FY2027 |
|---|---|---|---|
| Anti-Submarine Warfare (ASW) Distributed Search | 11.8 | 23.5 | 18.8 |
| Anti-Submarine Warfare (ASW) Precision Localization | 3.7 | 3.6 | 2.9 |
| Anti-Submarine Warfare (ASW) Surveillance | 27.7 | 21.0 | 18.8 |
| Marine Biology | 2.6 | 2.5 | 1.1 |
| Undersea Weaponry | 14.4 | 13.7 | 10.9 |

> R-2A activities carry the prior, current and budget year only — no five-year plan. Coverage is partial, so count them, never total them.
