Quick Reaction Alert
Quick Reaction Alert (QRA) is the state of readiness and modus operandi of air defence maintained at all hours of the day by NATO air forces. The United States usually refers to Quick Reaction Alert as Airspace Control Alert. Some non-NATO countries maintain a QRA, either full-time or part-time.
