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.
Lt. Gen. Dan Caine, nominee to be chairman of the Joint Chiefs of Staff, told the Senate Armed Services Committee that the Defense Department needs to upgrade its electronic warfare capability and its EW training ranges; just as his predecessor said at his own confirmation hearing.
