L-3 Communications selected the Gulfstream G550 Conformal Airborne Early Warning (CAEW) aircraft to host the US Air Force’s Compass Call program after their analysis and sharing that with the program office, USAF spokeswoman Ann Stefanek said in a statement.

Despite the objections of Bombardier and Boeing, the U.S. Air Force awarded  L3 Technologies an undefinitized contract action for The Compass Call “crossdeck” program which will transition mission equipment from the USAF’s existing fleet of Lockheed Martin EC-130H onto a new airframe.
