Class C shuttlecraft

The Disco-type shuttlecraft was a Federation spacecraft, a shuttlecraft in Starfleet service in the 23rd century, and from the 25th century onwards. In the mirror universe, the Terran Empire deployed shuttles of this type on Imperial Starfleet ships. This type of shuttlecraft, and its mirror counterpart, designated mirror universe shuttlecraft, re-entered Starfleet service in the early 25th century.

History and specifications
The Disco-type shuttle was in service as early as the 2230s. 

Its shape was roughly oblong, with a tapering front that housed the cockpit for the vessel's pair of pilots. The aft section was slightly enlarged and appeared more boxy. The craft's impulse engines and aft hatch were located here. The main cabin for passengers was located in the long main section between cockpit and aft section. The shuttle's pair of warp nacelles were fitted snugly to the either side of the ventral hull, without nacelle pylon in between. 

In 2256 and from 2409, vessels of this type were armed with S-rated phaser beam array and photon torpedo launcher, meaning these had 360° range and could only be equipped on shuttles. The minimum rank for a commanding officer to own such a craft was lieutenant. However, only Starfleet CO's originating from the Federation-Klingon War of 2256-2257 period could own a Disco-type shuttle in the 25th century. 

From the 25th century onwards, vessels of this type could access the Federation transwarp network. When owned by a vice admiral, this shuttle class was equipped with quantum slipstream drive. 

Livery
In the 25th century, the design of the Disco-type shuttlecraft allowed its mothership's commanding officer to choose from different designs of livery, which could be modified further at starbases. These options were numbered Types and Veteran. 

In the mirror universe, the Terran's version of the ship matched the design but its hull was emblazoned with the Imperial Starfleet insignia. (ARC website: The Mirror Engle Carrier Leads a New Infinity Lock Box!)

History
Circa 2239, the SHN 03 brought the Kelpien Saru and Lieutenant Philippa Georgiou from Kaminar to the USS Shenzhou. 

By the time the Federation-Klingon War of 2256-2257 raged, the Disco-type was the standard Federation shuttlecraft for Starfleet. Shuttles of this type were held in a hangar at Starfleet Academy, and in the shuttlebay of the USS Malachowski. 

In 2256, J'Ula escaped from the USS Glenn (NCC-1030) aboard a Disco-type shuttle with stolen plans for the spore-activated displacement drive. Justin Straal rigged the shuttle to explode aboard her cloaked ship, the, damaging it. 

When Starfleet captains from the Age of Discovery were dragged into the year 2409 by J'Ula's spore-based weapon, their Discovery-era ships retained their complement of Disco-type shuttles, and also received the Type-8 shuttlecraft. 

In 2410, Starfleet gained access to the, and its type of tier 6 mirror escort carriers. Ships of the class came equipped with a hangar housing Disco-type fighter-shuttles. (ARC website: The Mirror Engle Carrier Leads a New Infinity Lock Box!)
