USS Enterprise

The Enterprise or USS Enterprise (often referred to as the "starship Enterprise") is the name of several fictional spacecraft, some of which are the main setting for various television series and films in the Star Trek science fiction franchise. Star Trek art director Matt Jefferies was the primary designer of the original Enterprise, which was originally named Yorktown in series creator Gene Roddenberry's first outline drafts of the series. Jefferies' experience with aviation led to his Enterprise designs being imbued with what he called "aircraft logic". However, Jefferies years later confessed to have taken some inspiration and artistic license from electric stove coils.- memory-alpha.org
