## What project 666158 buys

The Integrated Simulation and Analysis project funds activities that develop and support integrated analysis and digital engineering tools for the Capability Development Enterprise. In addition, the project develops tools and methodologies to support required analysis and studies; this produces system performance representations/models, environments, architectures, digital artifacts, data, and tools that underpin variable fidelity, stand-alone, interactive, and distributed simulations. The project incorporates Mission Engineering and Digital Engineering enterprise tools and methods (i.e. Model-Based Systems Engineering [MBSE], Modeling Simulation and Analysis [MS&A] ecosystem) as the technical and digital underpinning for the simulation models/ behaviors; it develops and maintains digital records for future analytical needs and serves as a template to identify, road map, and enable the Modeling and Simulation- centric portions of the acquisition life cycle and of operational missions. The project may fund IT and licenses to execute modern Mission Engineering and Digital Engineering. The project initiates and leverages studies performed by industry, academia, FFRDCs and UARCs that may be required to develop and create technology representative models and data. Program management support costs including, but not limited to, hardware, software, travel, contractor support services, civilian pay, supplies, facilities, and infrastructure. This program may include necessary civilian pay expenses required to manage, execute, and deliver Requirements Analysis and Maturation capability. The use of such program funds would be in addition to the civilian pay expenses budgeted in program element 0605829F, 0605831F, 0605833F, and 0605898F.

## Activities (R-2A) — 1

| Activity | FY2025 | FY2026 | FY2027 | Move | Page |

> Activities carry the prior, current and budget year only — no five-year plan. In the request year they partition this project exactly; in earlier years they can under-cover it.

### Modeling, Simulation, Analysis, and Experimentation Ecosystem

-Continue to develop, enhance, and proliferate enterprise MS&A capabilities on behalf of the USAF and DAF (and Joint MS&A community through tool interoperability and reusability). - Continue to implement USAF Acquisition network for classified analysis while providing a production development environment with stable RDT&E investment to…

## What is NOT on this page

Congressional marks, the R-2 mission description and acquisition strategy, the industry vs government split of the whole request, and related program elements are recorded at **program-element** grain — an NDAA mark lands on a PE, never on a project.
