U.S.S. Jubayr, Courage class

That is my fan-made recreation of one of the starships seen is the season 3 of Star Trek: Discovery. It is an Courage class USS Jubayr

The vertical-oriented hull resembles older 25c nausicaan ships from Star Trek Online (especially Vandal, Scourge and Ravager classes) albeit much bigger and smoother. The ship doesn't have specific orientation, so she may fly "backwards" in some cases. Just for me, the bigger part of the ship is her front, smaller part - back. However, in Star Trek Online, the front and back are reversed (but the ship can change her orientation while transitioning from science mode to tactical mode - the ship turns 180 degrees mid-flight while maintaining her course).

The name and registry are not seen at all in the series (with exception of those from USS Song), but they come from a databook "Star Trek Shipyards - Starfleet ships from 2294 to future".

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