The Klingon civilian transport is a class of ship used by the Klingon Empire in the 24th century.
In 2372, a ship of this type crashed in a mountainous region on Galorda Prime. All aboard were killed.
Three months later, another civilian transport was used in a plot by the Empire to extradite Worf back to Qo'nos. The ship, under cloak, entered a battle between the USS Defiant, a Klingon bird-of-prey and a K't'inga class battleship. The transport decloaked, and while in the process of doing so, Worf ordered the Defiant to fire quantum torpedoes, destroying it. Luckilly for Worf, the transport was empty. The Klingons had faked lifesigns and had used the names of the ship that crashed on Galorda. (DS9: "Rules of Engagement")
