Klingon starships: In the "Star Trek" franchise, the Klingon Empire makes use of several classes of starships.  As the Klingons are portrayed as a warrior culture, driven by the pursuit of honor and glory, the Empire is shown to use warships almost exclusively and even their support ships, such as troop transports and colony ships, are armed for battle.  This contrasts with the exploration and research vessels used by Starfleet, the protagonists of the franchise.  The first Klingon ship design used in "", the D7-class battlecruiser, was designed by Matt Jefferies to evoke a shape akin to that of a manta ray, providing a threatening and instantly recognizable form for viewers.  The configuration of Jefferies's design featured a bulbous forward hull connected by a long boom to a wing-like main hull with the engine nacelles mounted on each wingtip.  Though a variety of Klingon ships have appeared in "Star Trek", their design generally conforms to this style.  Most Klingon vessels were physically built as scale models, although later computer-generated imagery was used to create the models.  In recent years, many of the original studio models have been sold at auctions.
