Concorde cruised at M2 at FL550-600, well inside the snap-up frontal attack envelope for the AIM-7/Skyflash. (150-180 TCA)
It flew a couple of trail sorties in the North Sea using a figure of eight route through a set of CAPs with Ltgs with Redtop and F-4s and successful practice shots were taken.
SR-71 flew at 70K+ and M3. Height was outside the snap-up envelope, plus the closing speed meant the missile fusing would detonate the warhead too late to engage.
