“How did it get to that speed?
FUEL and TIME”
That’s true.
But you didn’t read my post. It’s launched from an aircraft cruising at high speed (i.e., supersonic). The aircraft spends its fuel and time to get up to speed, then kicks off the missile scramjet engine.
Fuel usage is not a concern with this missile concept. It’s all the other stuff that comes into play that makes it extremely difficult to develop.
I did read your post, but I dont believe the missile pictured is a scram jet type, look at the intake: you honestly think an orifice that small is going to receive enough air to force feed a scram jet that small?
And from what aircraft are they going to launch a missile from an initial speed of mach 1.5 or greater to start the scram process?
That missile seen there is a small missile, does not contain enough fuel on board for more than a 60 second burn, regardless of it’s operating method, and if it reached mach 5 using a scram jet method of propulsion, it would be out of fuel within 60 to 90 seconds of burn time. The actual missile would have to have a 10 to 12” diameter to contain the fuel, avionics and warhead to even be a threat and not just a technology demonstrator.
that means the aircraft that launched it was within range of any and every counter measure and anti-aircraft system known before it reached it’s maximum velocity
speed is nice, but it has to actualy get to the target safely and within 15 miles to launch, paint the target, and release and stay on course and correct itself at that speed.
