The Air Force has suspended training missions for B-2 stealth bombers because of problems with the aircraft's crew ejection system.

Ten of the service's $2 billion bombers are at Whiteman Air Force Base. Eleven other bombers in production are at Edwards Air Force Base in California and will be repaired as well.The suspension was precautionary and should last seven to 10 days, officials said. It would not interfere with the aircraft's ability to be deployed in combat, should that be necessary, the Air Force said in a statement Thursday.

The Air Force said the suspension was due to "a potential problem associated with initiators which operate the air crew ejection system." It said the potential flaw had been discovered during routine testing.
