Evolved Strategic SATCOM (ESS)

The Evolved Strategic SATCOM (ESS) program is a significant initiative under the Air Force, aimed at enhancing the United States' strategic satellite communications capabilities. Its primary objective is to replace the existing Advanced Extremely High Frequency (AEHF) services with a more resilient and survivable system. This system supports global, integrated communications for the National Command Authority, Combatant Commanders, and joint warfighters. The program ensures that strategic SATCOM capabilities remain robust against emerging threats, providing secure, jam-resistant communications across ground, sea, and air assets.

ESS is divided into several segments to expedite capability delivery by FY 2032. The Space Segment emphasizes rapid prototyping and technology maturation through Middle-Tier Acquisition strategies to reduce risks and enhance resilience. Concurrently, the Ground Segment, known as GRIFFON (Ground Resilient Integration & Framework for Operational NC3), focuses on developing a modular and cybersecure architecture. This architecture integrates modern software practices with legacy systems using agile Modular Open Systems Approach principles to efficiently onboard mission applications and services.

The Crypto Segment of ESS is tasked with developing NSA-certified End-Cryptographic Units essential for secure communications encryption across various system components. Its modular acquisition strategy encourages industry competition and collaboration with small innovative partners through the Space Enterprise Consortium. By requiring prime vendors like Lockheed Martin and Raytheon to engage small businesses for a significant portion of prototyping work, ESS aims to integrate innovative practices while reducing costs and development timelines.

ESS adheres to stringent NC3 classification requirements and addresses capability gaps identified in strategic studies. The program's architecture aligns with validated operational concepts and capability documents to meet legacy AEHF requirements while enhancing resiliency and cybersecurity. Through its comprehensive approach involving multiple parallel efforts, ESS seeks to deliver a robust strategic SATCOM ecosystem capable of supporting future military operations in contested environments.
