I made that statement offhand, because I was remembering Klub did that, but I'd forgotten Klub's name at the time. Then Viky said it and I was like "yay that's the one".
It's basically the optimal unless you have hypersonic cruisers. You get the range of a subsonic with the terminal effectiveness of a supersonic. The only problem is that it's vulnerable to interception by fighter aircraft in the Outer Defense Zone during flight. Supersonic cruisers are somewhat of an annoyance in that shooting them down is hard during all phases of the flight, which is why Outer Defense Zone fighters would be tasked with intercepting and destroying the launch platforms before they could fire, ideally.
Given that a carrier battlegroup's "long arm of the law" is about 250-450 kilometers along the threat axis, if we take fighter patrols and pickets into account and add another 100-200 kilometers for weapons range at the patrol distance, you're going to be in for a rather long period of puckering before the other guy is.
Of course if you're that serious, you'll be shotgunning megatons of ordnance at a battlegroup. And the battlegroup still won't be knocked out of the fight despite its escorts evaporating in multiple miniature suns.
