"The exercise scenario for the final week of COPE North 2019 evolved from a humanitarian assistance and disaster relief operation to combat air operations after an aggressive nation downed a friendly aircraft," the release said on Friday. "This brought about a combined effort from three nations and an opportunity to integrate and project air superiority to deter further aggression and when necessary, defeat the aggressors."
"When you look at the combat capabilities that are exercised for this event, air superiority, air interdiction, electronic warfare, tactical airlift, air refuelling — all of these are critical capabilities to all of our nations to be able to deter conflict, and in the event that deterrence fails, these are war-winning capabilities," US Forces Japan and 5th Air Force commander Lieutenant General Kevin Schneider said in the release.
