Fundamentals of Evolved Strategic Satellite Communications (ESS) Training by Tonex
The Evolved Strategic SATCOM (ESS) program is the U.S. Department of Defense’s next-generation strategic satellite communication system, designed to replace and enhance the Advanced Extremely High Frequency (AEHF) constellation. This foundational course introduces both technical and non-technical professionals to the architecture, objectives, capabilities, and development lifecycle of ESS.
The course balances technical depth for engineers with accessible explanations for program managers, planners, and acquisition personnel.
Learning Objectives
By the end of this course, participants will be able to:
- Describe the mission and architecture of the ESS program.
- Understand the key differences between ESS and AEHF systems.
- Identify the technical components of ESS, including space, ground, and terminal segments.
- Explain how ESS supports strategic nuclear command and control (NC3), allied interoperability, and secure warfighter communications.
- Explore system-level engineering practices for secure, resilient SATCOM.
- Navigate acquisition and development milestones, including prototyping and risk reduction.
- Support ESS-related projects from both engineering and non-engineering roles.
Target Audience:
- Space systems engineers and SATCOM developers
- DoD acquisition professionals and program managers
- Strategic communications planners
- Military officers (J6/C5ISR roles)
- Government and contractor staff supporting ESS
- Cybersecurity and survivability specialists
- Technical and non-technical decision-makers
- Allied partner liaisons and coalition users
