Star Trek Expanded Universe

The Toron class was a type of shuttlecraft fielded by the Klingon Empire during the 24th century.

The Toron was the standard shuttle used by the Klingons. The exact configurations of the shuttles varied depending on their user as they were often reconfigured to suit the owner's need. (Ship Recognition Manual, Volume 3: Ships of the Klingon Empire)
