The Global Hawk Block 20, seen here in a hangar in Palmdale, Calif., will receive the Battlefield Airborne Communications Node, or BACN, as a result of an Air Force contract awarded June 24. The contract, let by the Electronic Systems Center at Hanscom AFB, Mass., also calls for first outfitting two BD-700 business jets with BACN, meeting a joint urgent operational need.
