Just a question here... There is probably something I'm missing.
IIRC, the Mk 16 dual stage missile has a useable range of about 40 million KM. The Mk 23 three stager seems to be used successfully at between 55 and 65 million km. With Apollo that extends out to about 80 million km.
The Catapharact, according to what I remember has a range of about 15.5 million klicks.
So how does this end up meaning that the range advantage has been overcome?

The ranges given are powered ranges, without including a ballistic component. Any missile with multiple drives or stages can put in a ballistic component in between them to get arbitrarily long range. You "just" get issues of:
(1) the target being too far from where the last ballistic stage ends for the final powered stage to catch it from there, due to its own movement in the meantime*, and
(2) the missile being practically on its own so far downrange with light speed control lags applying, so that even if it can reach, it will be helpless against the target's defenses, or too nearly helpless for the whole salvo to produce effective results.
* (Even a single-drive missile could have a ballistic component at the end, leaving the last "stage" as the stand-off attack range of the actual laserhead against the target. That would be enough against some target with absolutely predictable movement, but any final drive stage increases that range astronomically, in that familiar, literal, "space is BIG" sense.)
