Sound barrier at sea level is 761. Most missiles that are fired from a Tactical aircraft are fired from much higher altitudes where the speed of sound decreases due to the thinner atmosphere. Missiles accelerate at a rate suitable enough for the missile to be under the strain of 14+G's and travel at supersonic and hyper sonic speeds. Hyper sonic being a value greater than 5 times the speed of sound. You must understand that modern warfare is advanced as such that pilots often fire at ranges of thirty to fifty miles away from their targets thus requiring ordinance capable of reaching their targets at great distances with great accuracy at staggering speeds.

Yes. The missile would only need a small thrust to speed it up to the speed of sound -about 760mph. Most modern missiles fly several times the speed of sound anyway, even if they are not given a push start by the plane.

Yup.
A missile that didn't break the sound barrier would be pointless anyway as it could easily be evaded / intercepted. Most travel between 2 and 5 times the speed of sound.

I would have thought yes since the missile is already travelling at 750 mph in the plane therefore if you then further accelerate it surely it should speed up?
I am not a scientist though so probably way off :)

It already has.
750 mph is supersonic. And then some. Most missiles, depending on type, are supersonic--some up to three times the speed of sound.
670 mph at sea level by the way.

Depends on the speed and direction of the missile.

Of course.
The rocket launch speed is relative to the plane, and so the two speed add relative to the air or ground.
This rule only breaks down at non Newtonian speeds, when special relativity becomes important.

if the missile is located outboard it has already broken it. I don't think you rebreak it at mach two, but I must plead ignorance....hmmm,..went and looked. 761mph! Who knew! sorry.

it has to be. since supersonic planes exist ....supersonic missiles should come to play otherwise there would not be a purposes of its their existense
