The Hou-Yi class[2] was a 23rd century Federation starship, a stealth[2] mothership[3] in Starfleet's covert ops organization Section 31 service in the 2250s decade. (DSC episode: "Such Sweet Sorrow", DSC Issue 32: "Section 31 Hou-Yi-class")

History and specifications[]

Technical specifications[]

In the 2250s decade, capital Section 31 stealth ships shared a design lineage that was based on the smaller intel science destroyer. Apart from a size difference, the S31 ship classes shared the design for warp nacelles, nacelle pylons, bridge module and deflector dish.

Additionally, four capital ships shared the same arrowhead-shaped saucer section with a characteristic negative space between bridge and bow. The hull material was typically black. (DSC Issue 32: "Section 31 Hou-Yi-class")

The standard configuration of the Hou-Yi class consisted of a saucer section placed directly atop a flat, narrow secondary hull.

Above and below the saucer's trailing edge, a warp nacelles were suspended from short nacelle pylons. The bussard collectors and warp plasma in the nacelles were of the same shade of blue. All windows were blue and could be switched to white light, while the bridge dome remained white.

Rear-facing red impulse engines were attached to the saucer section. The shuttlebay was located at the aft end. A rollbar spanned across the dorsal hull.

Overall, the configuration mirrored the contemporary,[5] smaller Reliant-class[6] used by Starfleet The extra pair of dorsal warp nacelles between the rollbar set the Hou-Yi design apart from the Miranda and Shiva. (DSC Issue 30: "Section 31 Shiva-class")

The Hou-Yi-class starship's overall length was 645.26 meters (DSC Issue 30: "Section 31 Shiva-class")

The orientation of the nacelles, rising up from atop the pylons, contrasted the flat orientation of the smaller intel science destroyer.

The ship's widest points were either side of the saucer, measuring 421 meters from port to starboard. The total height of the Hou-Yi was 170.8 meters, including the upper- and lowermost nacelle edges. A variant of the design was the Shiva-class, which lacked the upper nacelles. (DSC Issue 30: "Section 31 Shiva-class")

When the Hou-Yi entered a cloak-like stealth mode called "dark mode", the pylons and nacelles folded inward, making the ship smaller. In dark mode, light sources were also eliminated. (DSC Issue 32: "Section 31 Hou-Yi-class")

A key tactical advantage was the ability to deploy scores of Section 31 drone swarms that normally filled the skeletal saucer section wings on either side of the central spine. They were unpiloted craft armed with phasers. (DSC episode: "Such Sweet Sorrow, Part 2")

Service history and disposition[]

In the 2250s decade, the secretive Federation intelligence branch Section 31 operated a fleet that included Shiva-class motherships. They could deploy Section 31 drone ships in a swarm. One of the ships in service at the time was the NI-0064. (DSC Issue 30: "Section 31 Shiva-class")

In the year 2257, the artificial intelligence Control assimilated Captain Leland and assumed command over the entire Section 31 fleet.

At the Battle near Xahea in 2258[7], Control's fleet engaged the USS Discovery and USS Enterprise in combat in a bid to seize the Sphere data. (DSC episode: "Such Sweet Sorrow")

The NI-0047 was one of the Shiva-class stealth ships joining the battle with its swarm ships. (DSC Issue 28: "Section 31 Nimrod-class")

Control, in the body of Leland, was temporarily defeated and its fleet destroyed. The Discovery was guided by the Red Angel through a rift into the 32nd century. (DSC episode: "Such Sweet Sorrow, Part 2")

USS Curie in 3189.

By the 31st century, Federation Starfleet deployed four-nacelle ships that resembled the basic arrangement of the Hou-Yi. Modifications of the design included a recognizable but filled-in space where the Hou-Yi's negative space had been. The nacelle pylons were removed to allow for detached nacelles, and the rollbar was absent. (DSC episode: "People of Earth")
