During Zulu Alert Scrambles the F-4 Phantoms had to be airborne within 5 minutes of horn going off
Noteworthy Zulu Alert is the air-sovereignty mission where fighters scramble to intercept unknown ADIZ (Air Defense Identification Zone which actually is airspace over land or water in which the identification, location, and control of unidentified aircraft is performed in the interest of national security) intruders or anyone else who shouldn’t be where they are.
As explained in the video the interceptors had to be airborne within 5 minutes of horn going off, while the usual loadout of the Phantoms for this type of mission consisted of 20 mike mike M61 Vulcan cannon, AIM-9 Sidewinder heat-seeking missiles and AIM-7 Sparrow semi-active radar homing (SARH) missiles.
According to the clip description, moments during Zulu Alert scrambles were so tense that “sometimes during taxi and takeoff you were still trying to finish strapping in.”
So sit down, enjoy the video and feel the adrenaline of a Cold War Era Zulu Alert Scramble.
