I actually found a launch from the Antietam that was fairly sharp
turner.

Like I said I've seen them turn faster than this.

Although most any modern SAM won't fly directly at the target, unless
the range is very short (or the guidance system is old and stupid).
Even with winged missiles, you usually get longer range if the missile
climbs into a semi-ballistic trajectory that comes *down* onto the
target. (There is also a tactical bonus: even alert pilots tend to
keep a much sharper watch for missiles coming up at them from below, so
coming down from above is rather more likely to take the pilot by
surprise.)
Understood. I was simplifying it a bit. More truthfully, the fire control
system computes a trajectory that the vehicle should be on to appropriately
close with the target (which might be a slightly lofted trajectory).
Obviously, since the missile is in its launch container, it doesn't actually
sense where the target is.
The vertical launch system launches the rocket nearly vertically and the
rocket then must get onto the trajectory calculated by the fire control
system. This is the quick turn you see.
The missile originally starts downrange on the trajectory that the fire
control system computed and then begins taking control of its own trajectory
as it integrates data about the target from its own sensors.
