## What project 674567 buys

Project 674567, Modeling & Simulation Foundations, develops and supports a software tool named Air, Space and Cyberspace Collaborative Environment - Information Operations Suite (ACE-IOS). ACE-IOS is used during major theater exercises to provide realistic intelligence, surveillance, and reconnaissance (ISR), electronic warfare (EW), information operations (IO), and cyber effects simulation. ACE-IOS is part of the cyber live-virtual-constructive (LVC) environments for use during Joint training of offensive and defensive ISR/cyber capabilities for the USAF, DoW, select coalition, and national agencies. ACE-IOS is also used at Air Force and Joint ISR operational training, conducted by the AF simulation centers worldwide. Warfighters train using ACE-IOS models and simulations with specific extensions in support of the United States Air Force (USAF) ISR schoolhouse. Robust ACE-IOS modernization is imperative to ensure that air, space, and cyberspace training and mission rehearsal activities can provide warfighters with realistic, interoperable, and readily available tools, data, and services. Planned ACE-IOS enhancements support of the users at mod-sim centers for multi domain capability and the USAF ISR schoolhouse. Specific cyber effects software extensions are required for warfighter training and exercising of tactical cyber mission forces (CMF).

**R-3 lines of work:** Product Development; Management Services.

## 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.
