This massive mushroom-shaped station was in service as early as the 2270s and continued operating into the late-24th century. Its design was suited for starbases and starship construction. The primary hull sat atop a thick, cylindrical central core and housed the main docking bay. Nearly halfway down the core was a smaller, hemispherical hull that contained another docking bay. At the base of the core was a spherical housing for matter/antimatter tanks and the impulse engines.

Known stationsEdit



Deep Space Station G-6 in 2248.

The G-type space station was in service from at least the mid-23rd century. It was much larger than its contemporary K-class stations, but had a similar layout. However, it did not have the discus-shaped primary hull or the lower shuttle bay module, instead, the central core was topped with a rounded command tower, while at the base was a sensor or communications dish.

Orbital office complexEdit

This relatively small, modular space station class came into service during the late-23rd century. The lower section housed shuttle and cargo bays. Multiple habitat and office modules could be attached to the central core which led up to a torus-shaped observation lounge or arboretum. Various structures or modules could be attached to the top of the core, such as botanical tanks. (TOS movie: Star Trek: The Motion Picture; TOS comics: "The Return!", "The Sentence")

Modular space stationEdit

Construction support station

A modular space station being assembled.

This type of station in use in the 24th century had a modular design which was suitable for various roles, such as starbases and support stations. The main hull consisted of a core of three conjoined cylinders with a large hemispherical dome on either end. The lower hemisphere had four landing pads located on its dorsal surface. Branching off the central core were smaller truncated hemispherical modules and circular habitats. The different components could be towed to a particular location and assembled within a drydock frame with tractor beams, workbees and Sphinx workpods.
