Dynametric tailfins
Dynametric tailfins were a design feature which Tom Paris had hoped to add while designing the  in 2375. According to him, they would add "sleekness and a sense of power" to the shuttlecraft.

While working on the craft's structural integrity, Paris attempted to add the tailfins when plans for the Delta Flyer were being considered, but they were quickly removed by Tuvok, who stated that they were purely decorative embellishments which served no practical purpose, and that they were not making a "hot rod".
