A US defense official said there has been no order given to move forward with any kind of operation against Iran using the B-2s.

As of Saturday, the planes are flying over the Pacific and appear to be headed toward Guam.

Trump is set to hold a meeting with his national security team in the Oval Office on Saturday and Sunday evening.

The White House didn’t respond to a request for comment.

On Friday night, eight US Air Force KC-135 Stratotankers took off from Altus, Oklahoma, according to data from FlightRadar24.

Over Kansas the tankers refueled two groups of planes, identified on air traffic control audio by their callsigns MYTEE11 FLT and MYTEE21 FLT.

Previously, the callsign MYTEE has been linked to particular missions involving B-2 bombers, with many social media flight trackers confirming that the aircraft refueled were B-2 bombers originating from Whiteman Air Force Base in Missouri.

Flight tracking data and air traffic control audio reviewed by CNN show the bombers refueled again off the coast of California, and over Hawaii.

On Thursday, satellite images revealed six KC-135 refueling aircraft positioned at Diego Garcia, a secluded island in the Indian Ocean, potentially serving as a refueling site for the bombers if they head towards Iran.
