Type 6 was a material option, an Alpha Quadrant Alliance designation for the visual appearance of a spacecraft's outer hull, i.e. a vessel's "skin". This version of Type 6 was available for Federation Starfleet starships and shuttlecraft. It was one of the new default materials for ships of the line introduced in late 2409 and early 2410.
