### Project 0000 — Ocean Wrfghtg Env Applied Res

This project provides the foundational environmental knowledge for undersea, surface and air-based warfighting technologies and effective operations anywhere on the globe, as well as the operation of unattended sensors and unmanned air, surface and underwater vehicles. This project includes the Navy contribution to broader federal research such as the National Oceanographic Partnership Program (NOPP), efforts aimed at understanding and predicting the impacts of underwater sound on Marine species, and efforts to improve extended range environmental prediction through coupled Earth system models. Major efforts of this project are devoted to gaining real-time knowledge of the Battlespace Environment (BSE), understanding the variability between processes in the world's ocean, atmosphere and coastal regions, and providing the on-scene commander with the capability to exploit the environment to tactical, operational, and strategic advantage. Research results are transitioned to the Fleet Numerical Meteorology and Oceanography Center and to the Naval Oceanographic Office where they are used to provide timely information about the natural environment for all fleet operations. Efforts include ocean and atmospheric analysis and prediction for real-time description of the operational environment from near space to the sub-seafloor, shallow water acoustics, sensors for undersea surveillance and weapon systems, and influences of the natural environment on Mine Countermeasures, Naval Mining, Anti-Submarine Warfare (ASW), Information Warfare, and Naval Special Warfare systems.

| Activity (R-2A) | FY2025 | FY2026 | FY2027 |
|---|---|---|---|
| Coastal Geosciences/Optics | 9.4 | 9.2 | 5.7 |
| Marine Biology | 3.5 | 3.5 | 2.5 |
| Marine Meteorology | 19.0 | 25.1 | 26.7 |
| National Oceanographic Partnership Program (NOPP) | 8.8 | 8.9 | 5.9 |
| Task Force Ocean (formerly Ocean Acoustics) | 26.8 | 24.1 | 19.2 |
| Physical Oceanography | 10.6 | 10.4 | 4.7 |

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

### Project 9999 — Congressional Adds

Congressional Interest Items not included in other Projects.

## Mission & acquisition strategy

Assuring access to the global maritime domain is ensured by technologies that reliably and accurately sense and predict the ocean, atmosphere and littoral environment. Coordinated distributed maritime operations is only possible when timely, actionable information is delivered to commanders. This program element (PE) addresses applied research to develop and exploit tactical understanding of the maritime environment to maintain U.S. maritime superiority and ensure national security.
