@dennisvvugt G is acceleration (positiv or negative, so change in speed), Mach is speed itself. G forces are a problem for humans, because you can quickly black out, because your heart is not able to keep up with it or can hurt and damage your organs, including your brain.

@eliweiss5119 Air defense is just what the words say: air defense. Such missiles got 1000km range, no air defense missile on this planet got that range, not even the superior Russian one. You would also need much more to sink a ship that what you need to down an aircraft, so the warhead is also not made for that. You can of course use the same kind of weapon to fire back, overall: this missiles CAN be used to sink ships. It's that fast to counter air defense so it will be very hard to shoot it down.
