RTX's (NYSE: RTX) BBN Technologies demonstrated a system that automatically reroutes military communications when networks face jamming or disruption, according to a company statement. The system, called PACE4ACE, received funding from the Air Force Research Laboratory.

The technology operates across military and commercial communication pathways, including satellite links and tactical radios. During testing, four geographically dispersed sites maintained connections when high-capacity links were jammed, with the system switching to alternative communication methods without operator input.

"For warfighters on the ground and in the cockpit, PACE4ACE helps ensure critical data never disappears, even under jamming," said Dr. Sam Nelson, principal investigator at RTX BBN Technologies.

The system features a compact architecture designed for space and power-constrained environments. It supports multiple communication bands and integrates with existing mission systems. The technology automatically selects optimal communication links and reroutes traffic in real-time as conditions change.

The demonstration involved collaboration between multiple organizations. Long-range radios were supplied by the Institute for Human & Machine Cognition in Pensacola, Florida, while Collins Aerospace, an RTX business unit in Ottawa, Canada, provided high-frequency support.

The project validates the U.S. Air Force's Agile Combat Employment concept, showing that dispersed air support units can maintain secure communications across combinations of satellite, radio, and low-power links in contested environments.

Work on PACE4ACE is conducted in Cambridge, Massachusetts. The development is supported by contracts from the U.S. Air Force Research Laboratory and U.S. Army Aviation and Missile Command.
