Mach 10 = approximately 7100MPH. Their math figures to be .2817hours or approximately 14+minutes from launch to impact. Taking into consideration that the missle needs to ramp up to that speed give it another 15 minutes or so to escape gravity and reach velocity for a total of 30 minutes.

Being as a scram jet will not work until Mach 3+ the missle would need to incorporate some sort of rocket booster or ram jet to achieve enough forward velocity for a ram jet to work adding to the time it would take to impact from launch.

My guess would be 30 to 40 minutes at best. I would need to sit down and do the math.

uh, yeah, sniper63, you took the words right out of my mouth, I was thinking the exact same thing! I’m working on the math as we speak...let me know what you get first and I’ll tell you if you’re right. ;o)
