What I'm asking is can a heavy object diving at extreme velocity maneuver effectively in such a short span of time and at such sharp angles.
Yes. How do you think endo/exo ABMs work? You think all they can do is fly to pre-determined point? You can see Interceptors do wild maneuvers too.
ABM can do strong G force manueveres up to the point prior to structural integrity loss, however since it goes against gravity it expends more energy, but it has more fuel since it hasn’t dropped its fuel tanks(stage 1).
BM has gravity pulling it down during descent so it flows with gravity thus it makes maneuvers easier per energy spent, however it likely jettisoned its tanks (stage 1 & 2) long ago thus it relies on fins/thrusters/or glide-skip to best ABM.
I mention Kinetic Energy penalty maneuvers and F-pole bleeds, yet no one listens. Patrames talks about it all the time as well.
ABM vs BM is a dance. BM does some dances and ABM does some dances who runs out of energy first loses.
Qiam = not a dancer, gets kicked off dance floor easily
Emad = not really a dancer, but will bust a move if needed
Keiyban = pretty good dancer
Fattah-2 = incredible dancer
Iran also deployed endo chaffs (flare like objects) + decoys that many confused with Iron Dome rockets.
