An anonymous reader writes "South Korea and Japan seem set to purchase the advanced American Grumman RQ-4 Block 30 Global Hawks. The UAVs will be a major upgrade to both nations intelligence gathering capabilities in light of recent regional tensions.
Japan and South Korea would not be the only non-US user of the advance UAV, "The Global Hawk is in U.S. and German service (the latter under the Eurohawk name) and is one of the largest UAVs in operation. Basically an unmanned U-2, it operates from 15,240 meters to 19,810 meters (50,000 feet to 65,000 feet) and has a loiter time on station of 24+ hours. The U.S. Air Force used it to monitor the Fukushima Daichi nuclear power plant after the March 2011 tsunami and earthquake, while the Japanese government is also believed to have “borrowed” Global Hawks to monitor areas of the East China Sea close to Okinawa Prefecture. (Japan is also interested in buying the UAV, with reports out of Tokyo saying that two to three could be inducted by FY 2015).""
