The Regula series of stations were designed as small, flexible platforms for long-duration scientific missions in isolated locations. These kinds of missions could last for years; keeping a science team on station for that length of time would require the commitment of either a major starship asset or a fleet of small science vessels relieving one another every few months. Either of these was a significant draw on resources, while a small fixed station would offer the same capability at a fraction of the resources.

The stations were designed to be as simple and quick to build as possible, while offering the maximum flexibility in equipment. The Regula 1 station incorporated a 30 metre diameter dome capable of holding a large system such as an optical telescope, while the interior spaces included Geoplastics and Thermonics labs [3] and a small particle accelerator ring.

The stations had very little armament - the shields were included largely to screen the station from naturally occurring background radiation during sensitive experiments, while small phasers were included to provide defence against larger meteors and to deter raiders.

The most notable of the Regula stations was the first, Regula 1. The Genesis Project created by Carol Marcus had profound political and military implications; by housing it in a remote outpost the Federation hoped to assist in maintaining the secrecy around Genesis. In any case, stage two of the Genesis project required a large and completely lifeless underground location in an isolated spot. [3]

Unfortunately, the isolation of Regula also proved to be a major drawback when the project was attacked by Khan and the stolen USS Reliant. The only vessel nearby was the USS Enterprise, on a training mission with a largely cadet crew. The Enterprise was eventually forced to cripple the Reliant, provoking Khan to detonate the Genesis device with a Mutara nebula. [3]

The Regula stations provided valuable service for many years, but they have now been replaced by larger and more capable designs. none now remain in service.

Film: Star Trek II : The Wrath of Khan


Seen only in "Star Trek II : The Wrath of Khan", the Regula station
was a reuse of the Orbital Office seen in "Star Trek : The Motion Picture".
The creators simply flipped the station upside down and added a large dome
to one of the circular modules - one of many cost saving features of the
second film. Regula appears to be significantly larger than the office
- the former can be well scaled from the travel pod attached to it, while
the latter can be scaled against the Enterprise as it pulls up to the station
for the first time.

My viewing of this scene indicates that the distance from the base of
the stations upper hull to the top of the ring below is about the same
as the distance from the base of the Enterprise saucer section to the top
of the Engineering hull. This distance is about 21 metres on the Enterprise,
and I have used this figure to scale Regula to 242 metres high, about three
and a half times the height of the orbital office.

Like the much larger Starbase 173, Regula has a dome on one of the circular
sections, and I have again speculated that this houses a telescope or other

The canon section of the specs page is based around ST II. So far as
I know, we haven't seen a station of this particular type since and so
I have speculated that they have now been retired.
