To provide a simulation product line that meets the modeling and simulation (M&S) needs of both the current and future force across the Army's M&S community. To eliminate the need for multiple simulation tools across the Research, Development and Acquisition; Advanced Concepts and Requirements; and Training, Exercises and Military Operations M&S domains. To provide software solutions supporting Live, Virtual and Constructive (LVC) applications by fostering common components, interoperability, standardization and reuse.


OneSAF is a next-generation, entity-level simulation that supports both Computer Generated Forces and Semi-Automated Forces applications. This enables it to support a wide range of constructive and virtual simulator system solutions. OneSAF has been integrated as the replacement SAF for the Aviation Combined Arms Tactical Trainer (AVCATT), the Non-Rated Crew Member Manned Module (NCM3), and Close Combat Tactical Trainer (CCTT). It is serving as the basis for subsequent modernization activities across the U.S. Army for simulators such as the Longbow Crew Trainer (LCT) and Transportable Flight Proficiency Simulator (TFPS). OneSAF was built to represent the modular and future force and provides entities, units and behaviors across the full spectrum of military operations. OneSAF has been crafted to be uniquely capable of simulating aspects of the urban operating environment and its effects on simulated activities and behaviors. Special attention has been paid to urban operations details including interior rooms, furniture, tunnels and subterranean features, and associated automated behaviors to make use of these attributes. OneSAF is unique in its ability to model unit behaviors from fire team to company level for all units for both combat and non-combat operations. Intelligent, doctrinally-correct behaviors and a range of constructive, gaming and virtually-based user interfaces are provided to increase the span of control for workstation operators. OneSAF combined with the U.S. Army Night Vision Image Generator (NVIG) Toolkit is providing a range of high-fidelity sensor system training capabilities and supporting analysis of future system capabilities. The OneSAF Environmental Runtime Component provides a range of terrain database services and capabilities already supporting LVC applications across the world and bridging a critical interoperability gap by establishing a common terrain basis. 

In addition, interoperability support is present for industry standards such as Distributed Interactive Simulation, High-Level Architecture, Military Scenario Development Language, Joint Consultation Mission Command Information Exchange Data Model and Army Mission Command System devices. As a cross-domain simulation suitable for supporting training, analysis, research, experimentation, mission-planning and rehearsal activities, OneSAF provides the latest physics-based modeling and data, enhanced data collection and reporting capabilities.

OneSAF provides a domestic release that is available to all U.S. government users and an international version to support non-U.S. requirements. OneSAF also provides a full range of training, development, technical support and on-site event support services.
