Aqua-shuttle

From Memory Alpha, the free Star Trek reference

The aqua-shuttle was a type of Federation shuttle stowed aboard the shuttlebay of Constitution-class vessels during the late 2260s.

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. (TAS: "The Ambergris Element")
