10 Times Star Trek Reused Ships And Hoped You Wouldn’t Notice
3. Promellian Battlecruiser/Skreean Ship
This particular model is the most unusual on this list, as it wasn't even designed for Star Trek to begin with. It was, in fact, designed by Steve Burg for the 1986 B-movie Night Of The Creeps. In that fact, the model was shown in a single scene, floating over a graveyard. As it would not be presented in full relief, only the ventral side was given any detail.
Once filming was completed, David Stipes came into possession of the model. When the script for Booby Trap came up, with precious little time to design the new ship that was called for, Stipes stepped in and loaned Trek the model.
Interestingly, while Gregory Jein was normally responsible for building the new ship, he and his company were busy working on The Hunt For Red October, in which Gates McFadden appeared while on her gap year from Star Trek.
The production team significantly altered the model, flipping it so that the ventral side seen in the film would serve as the dorsal side in the episode. It would be filmed once again for the Deep Space Nine episode Sanctuary, serving as the Skreean ship, with stock footage of this being used as Noggra's shuttle in Sons Of Mogh, and as an unnamed alien ship in The Muse.
