Ummm, F111's carry bombs, they are not interceptors. I guess they could attempt to crash into your theoretical Navaho, but the resulting wreckage sort of defeats the whole idea.
Rockets are exceedingly fast and have been known to shoot down aircraft.
Think 120 knots - two miles a minute - 40 miles = 20 minutes from outside radius to centre.
Moorabbin to MCG 10 miles - say six minutes = keep very close watch on this den of iniquity.
Defence in depth:
ASIC's
New Fence
Aircraft Locks
Destroyer
F18's
And perhaps one or two other things as well for good measure.
I'm going to paste my ASIC on the tail of my aircraft where the rocket can see it.
