They were taking part in an air combat drill, the Red Flag-Alaska exercise, hosted by the USAF at the Eielson Air Force Base in the US state of Alaska.
The training exercise, which allows pilots to execute air defence and strike operations in combat scenarios, started on May 8 and ends tomorrow.
Nine F-16C/D fighter jets and about 100 personnel from RSAF's Peace Carvin II detachment in Arizona, and another 67 aircraft from the US forces, are participating in the drill.
