The U.S. Air Force recently awarded Northrop Grumman Corp. a $372 million contract to begin designing an advanced electronically scanned array (AESA) antenna system as part of Increment 2 of the B-2 extremely high frequency (EHF) satellite communications program. The new antenna system will enable the B-2 Spirit stealth bomber to send and receive battlefield information securely by satellite up to 100 times faster than it can today. Under terms of contract, the company will complete the preliminary design of the AESA antenna system, demonstrate technology readiness, and prove its functionality using hardware prototypes. The required engineering design, manufacturing, assembly, integration, and test activities will take place at company facilities in Palmdale, El Segundo, and Redondo Beach, CA; Dayton, OH; and Tinker Air Force Base, OK. The three-increment EHF satcom program is part of an ongoing effort by the USAF and Northrop Grumman to keep the B-2 fully mission-capable against evolving enemy threats.
