ONE F-22 LOSS AT RED FLAG ATTRIBUTED TO BAD TACTICS: The U.S. Air Force says that its F-22 fighter's debut in a Red Flag aerial combat training exercise with coalition forces underscored the known attributes of the stealthy jet, though the demonstration did not include trials of its most exotic electronic attack capabilities. Employment of electronic attack tactics, which are inherently offered by the F-22's Active Electronically Scanned Array (AESA) radar, was not included in the exercise that took place this month. The friendly "blue" force lost one F-22 during the exercise, Col. Tom Bergeson, who was the air expeditionary wing commander for the Red Flag, says. He attributes the loss to a confusing "mulligan," whereby an enemy "red" fighter regenerated or re-entered the fight unbeknownst to the blue forces. "We made some tactical mistakes and one slipped through," Bergeson said. Bergeson also praised software developers for a quick turnaround after the four lead F-22s of a 12-ship deployment to Kadena Air Base, Japan, recently encountered navigation computer problems upon crossing the International Date Line. "It wasn't anything catastrophic," Bergeson said, though the computers would not have been able to provide accurate navigation data to divert locations without the fix. But the decision was made to send the aircraft back to Hawaii as a "better-safe-than-sorry approach." (Aerospace Daily & Defense Report)
