From the looks of it and given the Wells 'time' ship theme (science ship with some cruiser-like features? Aka a much stronger and more sci stations version of the Nebula?) I would guess the Korath class to be a strong science based raptor hull.
I would really hate to receive another cruiser for either federation or KDF. Science and Raptors are what each side has not received a strong z-store ship in more than a year.
Its 'time' .

The Wells class is actually a canon ship, not propaganda.

The Korath is Cryptic's own invention.
