In a significant advancement for military communications, the Air Force Research Laboratory (AFRL) is engaged in pioneering the creation of advanced antennas and radio receivers. These systems are designed to interact with various commercial satellite internet constellations, facilitating secure and versatile communication for military operations.

Set to initiate flight testing in late 2025 through early 2026, this initiative, termed Global Lightning, aims to enhance the military’s connectivity capabilities. It will enable seamless switching between different satellite networks to bolster resistance against potential jamming attempts and support the Pentagon’s ambitious Joint All Domain Command and Control (JADC2) strategy.

Noteworthy for its collaborative approach, the program accommodates input not only from the Air Force but also from Navy, Army, and Coast Guard specialists, focusing on both aerial and terrestrial platforms. The concept revolves around creating radios that communicate with numerous satellite systems, thereby integrating new technologies as they become available.

Since its inception with initial contracts in 2018, Global Lightning has seen considerable investment, amounting to nearly $500 million, allocated for contracts with various technology providers. Recent funding focused on developing antennas tailored to connect with a range of operational satellites in low, medium, and geosynchronous orbits.

The upcoming flight tests are designed to assess the stability and reliability of connections, ultimately striving to achieve adaptive communication across multiple satellite constellations within singular missions.

The development of innovative satellite communication systems by the Air Force Research Laboratory (AFRL) marks a transformative phase in military operations, focusing on crucial challenges inherent in modern warfare. While the initiative described in the previous article gives a foundational view, several key aspects remain to be explored.
