Air Force likely to retire Block 30 Global Hawks

The Air Force is likely to retire its fleet of Block 30 RQ-4 Global Hawk high-altitude unmanned aerial vehicles, which is surprising considering that the Global Hawk was on the verge of replacing the five-decade-old U-2 manned spy plane program, reports Defense News.

The Defense Department is not only planning to mothball recently acquired Block 30 Global Hawks, which gather imagery and signals intelligence, but also stop building the aircraft, the story says.

The aircraft is being terminated primarily due to its high cost to buy and maintain and also because it has failed to live up to the promises that the program had originally offered the military, defense experts told the publication. The Air Force declined to provide an official comment.
