Thank you for your interest in the Modeling and Simulation Enterprise (MSE).

M&S is a key enabler of Department of Defense (DoD) capabilities, supports the full range and scope of DoD missions and operations, and underpins innovative solutions meeting national security challenges, and saves resources. Over the past 20-plus years, modeling and simulation (M&S) has become pervasive, almost ubiquitous, throughout the Department... Read more

    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.

    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 collaborative forums.

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.
