We are pleased to announce the release of the Extended Air Defense Simulation (EADSIM) Version 20.0. EADSIM is a Government-owned many-on-many Simulation of Air, Missile, & Space Warfare. EADSIM is developed by Teledyne Brown Engineering for the US Army Space and Missile Defense Command and the Missile Defense Agency. EADSIM is used for Operational Planning, Mission Analysis, Military Utility Assessments, Integrated Air and Missile Defense analysis, Operational analysis, and training.

The following EADSIM capabilities have been improved in Version 20:​

  • Operator in the Loop
    • Multiple Command Level Focus
    • Improved Individual Aircraft Control
  • Coordinated Defense Fighter Support Package Operations
  • Simplified Rotating Radar Model Definition
  • Customizable Laser Dual Gimbal Slew Model
  • Additional Timing Effects Models
    • System Timing Errors
    • Operator Modeling Techniques (Combat ID and Engagement Focus)
  • Other Integrated Air and Missile Defense Enhancements

EADSIM is free for use by government agencies and their contractors.


EADSIM software runs on 64-bit Windows and Linux O/S.


EADSIM V20 has received an Army Assess Only Risk Management Framework approval.

Technical Support:​


EADSIM’s training approach is simple in concept, thorough in approach and provided in an interactive training lab environment. Model theory and operation are taught in a lecture format. Hands-on exercises use the theory and operation to build and execute scenarios, with each building upon the knowledge and skill of previous lecture elements. Application of this progressive training process to each of the model elements assures development of user skills and understanding of EADSIM.​

  • Basic Courses
    • EADSIM Fundamentals - This course covers the basic information and skills needed to develop models to evaluate system, technical and operational performance.
  • Advanced Courses
    • User Rules - Focuses on the concepts of EADSIM User Rules capabilities in operation across a variety of engagement types.
    • EADSIM Sensors - Covers details of various sensor models, from application of simple modeling techniques to detailed representations to associated C3 for emissions  control.
    • EADSIM Flex CDR/SAM – An advanced course that delves deeply into the building blocks of SAM/C3 modeling, including a greater learning of the outputs that illustrate performance and lead to Measures of Effectiveness (MOEs) and Measures of Performance (MOPs).
