and Northrop Grumman officials officially unveiled the Block 40 RQ-4 Global Hawk unmanned aerial vehicle at the company’s Palmdale, Calif., facility June 25. It is the first of 15 aircraft in the latest iteration of the high-flying reconnaissance UAV and includes the multi-platform radar technology insertion program (MP-RTIP) sensor. USAF expects to begin fielding the Block 40 aircraft at Grand Forks AFB, N.D., next year. In a company release, Duke Dufresne, sector vice president for Northrop’s strike and surveillance systems division, said that with the new sensor, which just completed initial testing last month, “the Block 40 aircraft will provide game-changing situational awareness for our warfighters with its unprecedented capability to detect, track, and identify stationary and moving targets.” The aircraft, AF-18, is slated to begin flight tests in July.
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.
