The Office of the Undersecretary of Defense, Research and Engineering (OUSD R&E), is discontinuing the M&S Catalog and associated guides and sites,
effective March 31st, 2023. We appreciate the community that shared information and we are eager to work with you as we build knowledge bases such
as the Digital Engineering Body of Knowledge (DEBoK) and The Modeling and Simulation Body of Knowledge (ModSimBoK).
The following websites/tools will be discontinued:
Please visit OUSD R&E Systems Engineering and Architecture at https://ac.cto.mil/engineering/ for information on new developments and key initiatives
in Digital Engineering and Modeling and Simulation. You can access the DEBoK at https://www.de-bok.org. The new ModSimBoK will attain full operational capability in Summer of 2023.
Please contact OUSD R&E with any questions or comments at firstname.lastname@example.org, or by visiting the M&S Webpage at https://ac.cto.mil/modsim/.
Effective immediately, the organizational designation for the Defense Modeling and Simulation Coordination Office (DMSCO) has become the Modeling and Simulation Enterprise (MSE). As an organization within the Office of the Deputy Director for Engineering (DD, ENG), we adopted this new name because it better reflects our focus on developing solutions to M&S problems. Our priority actions include: focus on prioritizing current efforts with new responsibilities; establishing a body of work responsive to the modeling and simulation enterprise challenges; and, standing up the new Modeling and Simulation Community of Practice (M&S CoP). If not already, you will begin to see this change reflected in email correspondence and calendar invitations. However, we ask for your patience while we work to update our respective websites, organization charts, etc.
The Department of Defense (DoD) Modeling and Simulation Enterprise (MSE) is the focal point for coordinating all matters regarding
modeling and simulation across the DoD for the Office of the Under Secretary of Defense (Research and Engineering) (OUSD(R&E)).
Modeling and simulation (M&S) is an enabler of warfighting capabilities. It helps to save lives, to save taxpayer dollars, and to
improve operational readiness. MSE assists the DoD to use M&S in a cost-effective manner through tools, policies, standards, guidance, and
The use of simulations and simulators to provide training procedures improves individual and collective capabilities. Military forces train
with a wide range of simulated weapons, ships, aircraft, and other vehicles in conjunction with live training on actual equipment. Within
the military--and in other professions--, M&S helps provide a safer and lower resource-intensive rehearsal capability for a wide variety of training.
Training is one of the most employed of the M&S applications, but there are many other ways that M&S enables Department’s functions. In
particular, M&S is used to analyze and inform the Department decisions in acquiring new capabilities, adopting new tactics, processing
intelligence, and testing systems before they are put into the hands of our fighting forces.
