Northrop Grumman has flight tested the Battlefield Airborne Communications Node—an Internet-based communications relay and information server that, flying at extremely high altitude, extends the range of line-of-sight radios to relay data to airborne and surface-based units. It can even link, via satellite, to distant command centers. USAF and Northrop flew the BACN aboard a high-flying NASA WB-57 test aircraft, acting a surrogate for USAF’s RQ-4 Global Hawk UAV. Officials plan to evaluate the system further during the Joint Expeditionary Force Experiment in April.
The rate of building B-21 bombers would speed up if the fiscal 2026 defense budget passes. But it remains unclear how much capacity would be added, and whether the Air Force would simply build the bombers faster, or buy more.
