U.S.S. Voyager J, 32c Intrepid class (Janeway class)

That is my fan-made recreation of one of the starships seen is the season 3 of Star Trek: Discovery. It is a 32c Intrepid class USS Voyager, named in honor of a main starship from Star Trek: Voyager. In Star Trek Online this ship is called Janeway class, in honor of Captain Kathryn Janeway, who was CO of an original USS Voyager.

The design is similar to the 24c Intrepid class and consists of a four floating sections - primary and secondary hulls with two nacelles (yes, there's no neck between the hulls).

The name and registry can be clearly seen in one scene in the series (when USS Discovery passes by Federation ships while approaching Federation headquarters). They're even referenced by characters onscreen.

I know, it's not as good as in Star Trek Online, I just tried to recreate the ship on my own.
