### Project 2222 — Modeling & Simulation

This Program Element supports activities and projects conducted by the Navy Modeling and Simulation (M&S) Office (NMSO). It enables technical and management initiatives that bring organization, focus, and efficiency to the development and use of M&S throughout the Navy and the Department of the Navy (DoN). NMSO provides a central organization for the formulation and implementation of policy and guidance in M&S and represents Navy interests in Department of War (DoW), Joint, and other agency initiatives. It funds efforts to define and coordinate Enterprise Navy M&S policy, execution, and guidance to evolve an interoperable and reusable core M&S capability consistent with the DoW's technical frameworks across the Future Years Defense Program (FYDP). Navy M&S priorities include interoperability and composability, effective capability use and reuse, and the incorporation of Model Based Systems Engineering (MBSE) products to help determine the networks, infrastructure, and data needed to support Enterprise Navy M&S capabilities. These leverage M&S standards, information systems, live virtual constructive environments, and collaborative design and development systems that support analysis, acquisition, training, and warfighting decision-making. NMSO's efforts are organized around three product areas: (1) Core Services: This activity provides leadership and essential planning, program and financial management, and execution of NMSO efforts as well as coordination with the other Services, the Office of Secretary of War (OSW), the Joint Staff, and other agencies. It also oversees initiatives to develop, promulgate, and track the policies and procedures necessary to support the creation of a robust and credible capability to create synthetic environments, accurately represent platforms and systems, predict outcomes, and provide inputs to Naval decision-makers and operational users. (2) Community Services: This activity provides M&S community-wide services, digital ecosystems, and technical exchanges; M&S plans and standards; and verification, validation, and accreditation (VV&A) handbooks and codes of best practice. It also develops M&S procurement guidance, digital engineering strategic goals, and supports M&S discovery and reuse capabilities across the DoN and Navy M&S communities.

| Activity (R-2A) | FY2025 | FY2026 | FY2027 |
|---|---|---|---|
| CORE SERVICES | 1.3 | 1.3 | 1.3 |
| COMMUNITY SERVICES | 2.6 | 4.9 | 7.2 |
| COMMUNITY EXPERIMENTS and PROTOTYPES | 6.7 | 6.2 | 7.9 |

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

## Mission & acquisition strategy

This Program Element supports activities and projects conducted by the Navy Modeling and Simulation (M&S) Office (NMSO). It enables technical and management initiatives that bring organization, focus, and efficiency to the development and use of M&S throughout the Navy and the Department of the Navy (DoN). NMSO provides a central organization for the formulation and implementation of policy and guidance in M&S and represents Navy interests in Department of War (DoW), Joint, and other agency initiatives.

This is a non-ACAT program. The focus of the Navy Modeling and Simulation Office's efforts is to facilitate and enable the efficient use of M&S by minimizing duplication of M&S efforts and maximize the reuse of M&S and data. The Navy's Enterprise M&S is being extended and scaled for applicability across the Department of the Navy to enable open, affordable and rapid integrated M&S capability development. This effort synergizes with and leverages/supports other funded efforts including Advanced Combat Systems Tech (RDTEN/PE 0603382N/Proj 0324) and Modeling & Simulation Support (OMN/4B3N).
