Summary North Korea has threatened nuclear strikes on Washington and Seoul.
WASHINGTON (AP) - The U.S. Air Force says it cost $2.1 million to send two nuclear-capable B-2 bombers on a training exercise over South Korea that was widely viewed as a show of force in response to threats from North Korea.
The service's Global Strike Command said Friday in a statement that the total flight time for the B-2s was 75 hours. The aircraft made the more than 6,500-mile (10,500-kilometer) round trip from the Midwest state of Missouri to a South Korean island range on Thursday.

Defense Secretary Chuck Hagel said the decision to send the B-2s for drills with South Korea was part of normal military exercises with a close ally and not intended to provoke a reaction from North Korea.
