Mach 1 is the speed of sound 768 mph. So if you had a plane flying at mach 2, which I believe we have, it would be close to 1,500mph. 450 miles away would be nothing.
Problem is, the probable choice of aircraft for a job like this (transport of 50-100 troops + weapons) would be a C-17.
Haven't had direct experience with them, but most likely maximum cruise is 550-600 MPH, which puts that trip out to around an hour.
OTOH, any Navy ship in the area would likely have a detachment of Marines on board to get support there in that half hour time frame. Even if the skipper had to beach the ship and make the Jarheads walk.
