I do not know. It looks a lot like the foundation of "Cruizerg" fleets in base HoI2, which would, if I am not mistaken, "warp into" firing range of all ships.
But then, normal SAGs do it right now, no need to have one and the same firing distance on all ships included, so yes, it probably is somewhat "new".
