The Bombardier Global Express is a large cabin, ultra long range business jet manufactured by Bombardier Aerospace in Toronto,Canada. There are currently three variants, the original Global Express, Global 5000 and Global 6000. The Global Express has been modified for military missions, such as the Raytheon Sentinel and the USAF E-11A. The Global Express can fly intercontinental ranges without refueling (e.g. New York–Tokyo) or between most two points in the world with only one stop. In this class the Global Express competes with the Airbus Corporate Jet, Boeing Business Jet and Gulfstream G550.

The Battlefield Airborne Communications Node (BACN) is an airborne communications relay and gateway system hosted on a variety of aircraft that provides flexible radio connectivity across the battlespace for airborne and surface operators. BACN enables real-time information flow between similar and dissimilar tactical data link and voice systems through relay, bridging, and data translation in line of sight and beyond line of sightsituations. By acting as a translation proxy between dissimilar communications systems, it allows interoperability without modification to the individual platforms' systems. While many of the interoperability problems were due to aging systems, there has been a special problem with stealth aircraft such as the F-22 Raptor, which, in the interest of security, could only communicate with other aircraft of its type.
Because of its flexible deployment options and ability to operate at high altitudes, BACN can enable air and surface forces to overcome communications difficulties caused by complex mountainous terrain and range while performing as a key node for tactical networks. BACN provides decision-makers at all operational echelons with critical information and increases situational awareness by correlating tactical and operational air and ground pictures. For example, an Army unit on the ground currently sees a different picture than an aircrew, but with BACN, both can see the same picture.
