The US Air Force has a new toy to play with in Osan:

The U.S. Air Force has deployed an updated version of its U-2 spy plane in South Korea, but a military official said on Monday the move was previously planned and not related to a possible North Korean missile launch.

In recent days, U.S. officials have said evidence such as photographs from spy satellites indicated that North Korea might be preparing to test launch a long-range missile.  Washington and others have warned Pyongyang that such a launch would pose a grave danger to regional security.

A USAF statement said that an improved U-2S Dragon Lady had arrived at Osan Air Base in South Korea on June 14.
