Which does imply that there is something of the original Enterprise still left within the redesigned ship or that Starfleet still considers her to be the original as she retained her original name and hull registry.
Ok but I'm struggling to find it: the entire hull is changed, the nacelles, the struts, the bridge and corridors and rooms are different, the warp core and impulse engines are changed, the weapon system is upgraded, new torpedo launchers, shuttles, etc. Everything is different.
I believe only externally, because it could be that various parts of the ship's interior spaceframe (or hidden skeleton) consist of reused original support frame members that were mated with new ones. Many of the interior bulkheads and deck plates could also have been retained, but repainted and refurbished to match the ship's new aesthetics.
But I think the ship would have new shuttles no matter what.
