The Class S-4 shuttlecraft was an aquashuttle, an auxiliary vehicle specifically constructed by the Federation Starfleet for submersible undersea operation as well as spaceflight in the 23rd century.

History and specificationsEdit

The S-4 class was an experimental shuttle type configured to explore deep oceans while having relatively similar internal control systems to the class F shuttlecraft. It featured a small power plant and specially belted and padded seats. Customized sensor arrays were specialized for underwater studies. This class of vessel was assigned for evaluation to several Constitution-class starships in the late 2260s. It was armed with a phaser cannon intended for defense against threatening undersea lifeforms, with firepower comparable to twice that of a phaser rifle. (FASA RPG module: Cadet's Orientation Sourcebook)

The S-4 class was designed primarily for maneuverability within a liquid, and secondarily as a spacecraft. As such, it took some experience to pilot the craft smoothly through a planetary atmosphere. The vessel was fitted with a recorder-sampler to collect data from the water. Storage lockers contained survey equipment, including tricorders and a self-powered mesh that would return samples of microbial life for analysis. The ship's window was made of a plexalloy.

Aquashuttle NCC-1701/5A was armed with two forward phasers set at stun force, charged by a power pack. It had a hatch and could also travel on top of the water like a boat. (TAS episode & Log Five novelization: The Ambergris Element)
