My fanmade 3D model of the Class J starship seen in the remastered version of Star Trek: The Original Series.
The Class J starship was a civilian craft used in the 23rd century coming in multiple variants, such as a space cruiser and a cargo ship. This model is based on the Stella, which was Harcourt Fenton Mudd's Class J starship, seen in the remastered version of the Original Series episode Mudd's Women. It has shorter nacelles and no larger windows compared to the other appearance of the Class J as the Aurora in the episode The Way to Eden. It was also very briefly seen in the episode Operation -- Annihilate!, obscured by the glare of the Denevan sun. This ship was designed by Mike Okuda, based on concepts for the original Class F shuttle by Matt Jeffries.
