The drone that the United States Air Force sees as the replacement for the venerable U-2 spy plane is now flying surveillance missions over Nigeria as part of the search for 276 schoolgirls kidnapped by the Boko Haram terrorist group. A Northrop Grumman RQ-4 Global Hawk flew a mission over Nigeria on Tuesday, according to an NBC News report.

The Global Hawk, which first flew in 1998, can stay airborne for up to 28 hours and has a range of 8,700 miles. It has a wingspan close to that of a Boeing 747, weighs more than 32,000 pounds, and carries the Hughes Integrated Surveillance and Reconnaissance (HISAR) sensor system, a down-market version of the infrared, optical, and synthetic aperture radar gear Hughes developed for the U-2.
