It's an airshow maneuver. Speed is life. USAF (and presumably other AF's) send out 2 to 4 ship (or if we look at Desert Storm, over 70 ships). If you "stall" or perform this maneuver, whomever is behind you might overshoot, but his or her buddy will nab you.

Check out Stroke 3. This is an F-16 strike on an oil facility in Iraq. Stroke 3 avoided six Iraq (Russian-made) SAMs /without/ deploying any counter measures. Simply amazing to listen to.

And here's a visual illustration of the entire strike package that went out. 76 aircraft as part of Package Q.

Fun (?) fact -- the first strike in Desert Storm was performed by eight Apache attack helicopters with two Pave Low helicopters leading them at NAP of the earth level at nighttime.

Like a CIWS? They get through far far too much ammunition to be mounted in a plane. Planes have just a few seconds of ammunition for a medium weight of fire, CIWS fire for tens of seconds at a much higher rate of fire at each missile.
