The US Air Force's E-11A plays a key role in connecting ground forces, aerial assets and command-and-control.

The E-11A is a modified large-cabin Bombardier Global Express 6000/BD700-1A10 business jet employed as a platform for the Battlefield Airborne Communications Node (BACN).

The BACN payload is an airborne communication relay and gateway telecommunication system that enables the E-11A used to provide extended aerial command-and-control both to aerial assets and to ground-based troops.

It consists of equipment and processors that extend line-of-sight communications and transmit video, voice, tactical data and imagery between combat forces too far away to communicate directly.

The BACN streamlines communications from Link-16, a tactical military data network employed by the US, NATO and other allies to communicate relevant air and missile threat data to defense systems.

It also coordinates transmissions among fighters, bombers and Joint Terminal Attack Control air support teams who direct the action of airmen.

The E-11A is referred to as "Wi-Fi in the sky" because of its ability to serve as a low earth satellite, supporting critical, real time communications.

This capability, in addition to the many other land, sea and air assets of the US military, enables the United States to help its allies in times of need against common adversaries.

Critical communications

The US Air Force's 430th Expeditionary Electronic Communications Squadron (EECS) is the only unit that operates the E-11A with the BACN payload.

The unit is specifically tasked with providing and maintaining critical communication channels for air, ground and maritime forces in active combat zones, including communication among American forces, their allies and coalition partners in the Middle East.

"This new E-11A will relieve the pressure on the rest of our fleet and enable us to sustain a high mission capable rate," said Lt. Col. Todd Arthur, the commander of the 430th EECS, upon receipt of the second outfitted aircraft.
