QRA (Quick Reaction Alert)

QRA, or Quick Reaction Alert, is a military protocol where fighter jets are kept on standby, ready to scramble quickly in response to a potential threat, such as an unidentified or hostile aircraft entering secured airspace. These jets are constantly prepared to take off within minutes to intercept and assess the situation, helping to protect national airspace and ensure security. Essentially, QRA is a rapid response system designed to provide immediate defense against air threats, maintaining vigilance and readiness for swift action when required.
