Perhaps. I do not know, but the answer (truth or falseness of your statement) depends upon each of their acceleration abilities. I also do not know how much the just shot down spy sattelite was being accelerated by atmospheric reentry forces (probably not much as it was dense and in very thin air) but what ever that "atmospheric acceleration" was the SM-3 had more capability - a lot more, I suspect, as many of the eariler developmental tests (which also were successes) took place in much denser air with less dense targets. (Mainly spent rocket shells) I have had no direct contact with this APL program but note that the standard missle was designed to kill incoming cruise missles, even those that might be "bobbing and weaving" via the large aerodynamic forces even their small wings and fins could achive in sea-level dense air. Thus, I think it would not be easy for an ICBM to survive by "ducking" at the last second. I also do not know the horizontal reach of an Aegis ship' with an SM-3. The ship defense standard missle can fly far beyond the contolling ship's radar horizon for low level targets - Perhaps killing a bomber 100 miles away horizontally. The new "coperative engagement" system allows one to fly from the far side of the carrier battle group entirely across it (50 miles or more wide) and kill a sea skimmer that the launching ship can not even see. I.e. as it flys, it will be handed off to other ships in the battle group. This allows the most exposed ship (the one on the side of the battle group from which the attack is coming) to conserve (instead of exhaust) it load out of standard missles. My APL office mate wrote the program that the US Navy uses both to load out (usually in a port, but possible in a calm sea) the ship's limited number of missle boxes for the amazingly wide variety of missles that fit in them. That program also automatically determines which one is shot in battle when several could be. There is considerable errosion of the box liners by the hot exhaust - one would like to have all boxes in need of relining during next port call, so that the ships puts back to sea "brand new" rather than come back to port sooner for reload with half the boxes never used. It took him more than a year to get everything optimized and yet have the program be responsive to the dynamic needs and even the style of different captains.
