10 Times Star Trek Reused Ships And Hoped You Wouldn’t Notice
8. Federation Fighter/Kralor Warship
Jim Martin designed the Federation fighter for the Deep Space Nine episode The Maquis. It was built with Star Wars as an inspiration, something Doug Drexler would later joke gave people acid indigestion! The model would return in Preemptive Strike, again used by the Maquis, before they would make their debut as true Federation vessels in A Time To Stand.
For these uses, having the ship appear with the Maquis and Starfleet suggested that these vessels had simply been coopted by the terrorist organisation, so having them play multiple roles made sense.
Slightly more difficult to explain, once again, was their appearance in the Delta Quadrant. In Nightingale, Harry Kim takes command of a Kraylor medical ship that bears a striking resemblance to these small attack ships. The design was altered to give the Nightingale a larger feel, adding decks to the ship via multiple lights, along with the suggestion of a beefier engine.
The ship would return a second time in Voyager, though this is somewhat excusable. In The Void, an Annari warship bearing the same configuration is encountered by Voyager, though the Annari had been established as combatants in a war with the Kraylor in the earlier episode. Much like the Klingons and Romulans, who's to say there weren't some shared ideas between the two?
