The Navy S3 Standard missile also has antisat capabilities.
The Block IIA missile has a top speed of Mach 15, and a maximum altitude of over 900 miles.
SM3 has whacked a bunch of satellites in orbit.
IIRC, the Ethan Allen has quite a record of sat-swatting.
I think the USN has pretty much demonstrated that it can take out any satellite it wants at any time, at least in LEO.
Problem with Aegis on a ship is it needs to be fairly near the orbital track and is not going to be able to reposition quickly. An airborne solution can.
