Oh boy, she's a beauty.
And TLR may correct me if I'm wrong, but it she does look quite a bit like an Albacore-class cutter with a regular Starfleet livery.
I have to say, I've always thought the Oberth-class is kinda funky looking but this video really makes her pop. Although I still wonder how the crew moves back and forth from the primary and secondary hulls. I suppose it has to be via those nacelle struts, though they look rather thin to support turbolift shafts, not to mention they are awfully exposed.
Maybe the upper deck/lower deck division is more stringently enforced on these ships .... 😀
