Two U.S. F-22 Raptors arrived in Japan Saturday, the first overseas deployment of the America's most advanced stealth fighters, the U.S. Air Force said.
Ten more F-22s were expected to arrive at Kadena Air Base on the southern island of Okinawa on Sunday, the Air Force said in a statement.
It said the deployment of the jets and more than 250 personnel from the 27th Fighter Squadron, Langley Air Force Base, Virginia, was a scheduled rotational assignment.
The fighters' arrival had been delayed by seven days due to bad weather and some problem with the navigation system software.
The newest fighters, which are successors to the F-15 fighters, will take part in drillings with U.S. Air Force units based in northern Japan and South Korea.
