The Type-18H shuttlecraft[1] was a 25th century[2] Federation auxiliary craft class, a shuttlecraft for personal use[1] by Starfleet personnel in the 2400s decade[2]. Through time travel, this type prochronistically entered service in the late 24th century.[3] (VOY episode & novelization: Endgame, The Official Starships Collection Issue Shuttle 24: "Janeway's Armored Shuttle", SOTL calendar: Ships of the Line 2020)

Service history[]

SC-4 at Starfleet Academy.

In an alternate timeline, Type-18H shuttlecraft had entered service by the year 2404. (VOY episode & novelization: Endgame)

In its design, it was an evolution of the Type-9 shuttlecraft of the 2370s decade. The newer type carried different warp nacelles, and the aft section behind the avionics bay had been enlarged to make room for a small cargo compartment. (VOY reference: The USS Voyager NCC-74656)

24th century Starfleet acquired the shuttle's specs when USS Voyager returned from the Delta Quadrant with its futuristic technology[2] in 2377. This technology was removed from Voyager, its databanks, and studied, all under the auspices of Project Full Circle. (VOY novel: The Farther Shore)

At some point after, the Type-18H shuttle SC-4 entered service and was launched from Starfleet Command. (SOTL calendar: Ships of the Line 2020, September image)


Standard version[]

In its standard configuration, the Type-18H shuttle could accommodate two flight crew and additional cargo. (VOY reference: The USS Voyager NCC-74656)

The shuttle was approx. 9.5 meters long and could maintain a speed of warp 6, which outcompeted the baseline Type-9 shuttle.

With ablative armor deployed.

The vessel was fitted with anti-Borg technology, some of which had been developed by USS Voyager in a decades-long journey across the Milky Way Galaxy. This included an ablative generator that, when active, could protect the hull by deploying a nigh-impenetrable ablative armor. In addition, the shuttle was fitted with a type of -stealth technology. (The Official Starships Collection Issue Shuttle 24: "Janeway's Armored Shuttle")

This stealth technology was incompatible with a 2370s-era Intrepid-class starship. (VOY episode & novelization: Endgame)

Weaponry consisted of a forward-facing[4] transphasic torpedo launcher[1] built into the ventral hull. (VOY reference: The USS Voyager NCC-74656)

While the ship's weaponry was no match for a Klingon Voodieh-class warship, the ablative could effectively protect the shuttle and its occupants from nadion-laced disruptor fire. (VOY episode & novelization: Endgame)

A Type-18H shuttlecraft could be controlled by its pilot in three ways: through tactile control consoles with LCARS touch interface, voice commands to the computer, and a neural interface. For the latter, a synaptic transceiver had to be implanted into the pilot's brain. (VOY reference: The USS Voyager NCC-74656)

Special operations[]

In 2404, Vice Admiral Kathryn Janeway fitted a Klingon chrono-deflector on the roof the Type-18H shuttle SC-4. This transformed the vessel into a timeship shuttle but the chrono-deflector burned out after one use. (VOY episode & novelization: Endgame)
