Star Trek - Aqua-shuttle

Aqua-shuttles were multipurpose vessels that were designed for traveling through space; through a planetary atmosphere; transporting across water, like a boat; and as well, were submersible, like a submarine. These vessels were also lightly armed with dual forward phaser emitters, as well as an aft emitter, which were powered by an internal power pack. (TAS: "The Ambergris Element")
