The D'Vahl is a cone-shaped Vulcan ship with "wings" on
either side of the front tip, and three engine pods, separated by
120°. It is capable of planetary
landings. The ship was in service during Earth's 20th century. Gallery: Vulcan Starships
D'Vahl appeared at the end of ENT: "Carbon Creek" and
rescued two of the three surviving crew members of the survey ship
(below) that had crashed on Earth. It is
quite obviously a design different than the survey ship. The model
reappeared without changes in ENT: "Awakening" and
"Kir'Shara", 200 years later (see below),
where it arguably has to be a different design.
The T'Plana Hath is a small survey ship of unknown class with a
threefold structure from the
21st century. It is capable of landing on a planet.
While there is no evidence in
"Star Trek: First Contact" itself, the secondary literature (namely ST
Magazine and Fact Files) makes it clear that it is the
entire starship that lands on Earth, and not a shuttle or dedicated
landing module. The name T'Plana Hath wasn't mentioned in
the movie either, but only in the script.
Well, the design with its many movable parts and the incredibly
complicated procedure of just opening the door doesn't seem to be very
The D'Kyr is a member of a yet unnamed class. The ship is
significantly larger than Enterprise. Like on the Surak class and the Sh'Ran, an
annular warp drive is employed, but here the hull of the ship splits,
thereby forming a second ring that wraps horizontally around the
engine ring. The (inner) engine ring may be tilted until it is
horizontal and hence completely covered by the outer hull. Gallery: Vulcan Starships
D'Kyr may be of the yet unseen Maymora class, but this is only
It is noteworthy that the Tal'Kir of the D'Kyr type from ENT: "Future Tense" is explicitly called "combat cruiser", just as the Sh'Ran
of about the same size shown in "Fallen Hero". But unlike we previously speculated, the Sh'Ran probably wasn't just a stand-in for
the not yet finished D'Kyr type but was built especially for "Fallen Hero".
The crew complement is stated by T'Pol in "Impulse".
We can see
the D'Kyr type with
an inclined engine hoop in ENT: "Future Tense",
"Impulse", "Bounty" and "The Awakening". In the first two episodes
this may be because of the battle damage. Still, it points to a hinge
between the outer and the (inner) engine ring that the inner ring
doesn't simply fall off when the ship is heavily damaged. In
"Bounty" the inner ring is completely horizontal and
submerged. We can safely say that the inner ring is not simply missing
because it is glowing blue on the inside -- we know from all other
appearances that the outer ring is never illuminated. Actually the
ring may have been brought to horizontal position to launch the
support craft (read on below). A sketch by John Eaves depicted in the
German Star Trek Communicator (issue #88) corroborates this
The D'Kyr was originally designed by John Eaves as D'Vahl ("Carbon Creek").
Vessels of the D'Kyr type have a support vessel with a smaller
version of an annular warp drive. This shuttle normally docks inside
the ship's engine hoop. On the D'Kyr the engine hoop may be inclined
up to the point where it is horizontal and completely inside the outer
ring in order to release the shuttle.
No name given
We can see the support vessel in most appearances of the D'Kyr class,
most clearly when we look at the ship from the aft, as for instance in
ENT: "Cease Fire". The support craft is docked at its
forward end in the center of the two rings. As a matter of fact, the
three times when the engine ring of a D'Kyr type was not in vertical
position, in ENT: "Future Tense", "Impulse", "Bounty"
and "The Awakening", the support craft was missing too! In the latter
episode we may see the support craft alone on the lower left (#3 on
the screen cap), but it is barely recognizable even on the DVD caps.
John Eaves envisioned the support craft as a kind of rescue vessel comparable to the US Navy's DSRV.

small vessels could be seen in ENT: "Awakening" and
"Kir'Shara". They are somewhat larger than
an Enterprise shuttlepod, maybe 12m long. They are better shielded
against the geomagnetic field near the Forge on Vulcan than the
Starfleet shuttle too. The model is an unchanged re-use of the D'Vahl from
"Carbon Creek" (see above). We
previously believed that at least the number of engine pods is
different, but both ships have three of them. Still
the fighter evidently can't be the same
design as a much larger interstellar ship from 200 years ago, so it is
listed as a distinct type.
This starship class is at least several years old as of 2151.
Archer mentions this ship class
to the Vulcan captain in ENT: "Breaking the Ice".
The ship's interior was visible
in ENT: "The Seventh". We can identify the ship from outside, as it is the
only vessel besides the NX-01 shuttlepod that does not lift off
after the fire has broken out in the station. Find the analysis of all
vessels on the page on unknown ships.
Menos's ship is essentially the same design as
the Klingon "rebel"
ship from ENT: "Judgment", without the nacelles, with a
cockpit window and with a door instead of the round docking port.

A picture of the satellite could
be seen on a display when Soval and Trip were talking about how to
disable it in ENT: "The Awakening". It may be a simple
cut&paste work using parts of the Surak class.
The Sh'Ran is a Vulcan combat ship type around 2151. The ring around the needle-shaped hull holds the warp drive. The ship is
equipped with much more powerful weapons than on Enterprise NX-01. Gallery: Vulcan Starships
The CGI model used for the combat cruiser Sh'Ran in ENT: "Fallen Hero" is clearly based on that of the Surak class. But
it is an entirely new mesh with dissimilar proportions (most obviously not quite as elongated) and dissimilar details. Doug
Drexler needed just two days for his Surak class (below). It could not be shown up close, but a high-resolution version would have
taken about two weeks. Pierre Drollet later built the Sh'Ran in high resolution.
Isn't the Sh'Ran simply a more detailed version of the Surak, with perhaps a few detail changes, but essentially the same ship
class? 3D artist Rob Bonchune on the issue: "The original model was just not up to snuff for what we needed. So it was
superseded. They are theoretically the same ship, not two different classes or types." However, the many obvious changes
to the model are a clear sign that it is indeed a distinct class, and the smaller windows insinuate a larger size. Aside from the
visual differences the two ship types also have different roles and different top speeds. Doug Drexler: "I like to think
that they are two different classes."
The Surak class is a Vulcan ship type around 2151. The ring around
the needle-shaped hull holds the warp drive. The ship is equipped with a tractor
beam and with more powerful beam weapons than on Enterprise NX-01. Gallery: Vulcan Starships
Doug Drexler quickly built this model for use in the background: "It was my first
pass concept model. Like all the concept models, it's low to medium resolution. Usually I only take 2 days to build something like
that, because Herman [Zimmerman] needs it pronto for approval. A high rez version was built later by Pierre [Drollet] so that they
could get close to it." This better detailed model would appear as the Sh'Ran in "Fallen Hero" (see above).
The Surak class is a positive surprise, because here is a starship that reconciles different design lineages
instead of screwing them up even more. First of all, it helps to
rationalize the SS Enterprise with its odd ring structure.
Secondly, the T'Pau from TNG: "Unification" has some sort of
ringed warp drive too. Thirdly, the color of the Surak is similar to
the one of the T'Plana Hath. We can hardly expect more consistency of
a starship design. Cordial thanks on behalf of all concerned fans! Yet, from an engineering viewpoint it is quite adventurous and
little logical to connect the ring to the hull at only one point at the bottom. Enormous lever forces would act upon the ship
which could have been significantly lowered just adding a few tiny spokes. A preliminary version by Doug Drexler had additional
struts, but they were removed on the final model.
The Surak class first appeared as the science ship Ti'Mur in ENT: "Breaking the Ice",
then as the Ni'Var in "Shadows of P'Jem". The color was
switched from red to brown between the Ti'Mur and the
otherwise identical Ni'Var, in addition the lighting of these two
ships is not quite the same.
The Surak class is depicted upside down in Daniels's files in ENT:
"Future Tense". I assume this is accidental and not yet
another ship class (some other vessels on that display are upside down
too, if I recall correctly).
The class name of the Ti'Mur may have been supposed to be "Suurok"
as in the close-captioning of the episode "Breaking the
Ice", and the Fact Files confirms that. On the other hand,
a more prominent article about the ship in Star Trek: The Magazine makes it
clear that the name was indeed supposed to be "Surak". This class name is no problem, if it remains an
exclusively Vulcan design, as opposed to the later Surak class of
Starfleet. I take it that "Suurok" is simply a tentative spelling or something
alien-looking made up based on the pronunciation in the
episode because a part of the script was accidentally not available.
The latest suggestion about the name comes from the Japanese Fact
Files, where there are suddenly two classes, the science ship
Suurok and the combat cruiser Surak. The author
obviously turned the name dispute into an advantage. Yet, it seems
idiotic that the two classes would have names that sound the same,
even if there may be a slight difference in the original Vulcan
The ship type with its characteristic crescent-shaped warp engines
first shows up as the civilian ship Vahklas, not under control of the Vulcan High Command,
in ENT: "Fusion". T'Pol is a bit surprised and says that "this class of vessel hasn't
been used for a long time". The ship is somewhat shorter than Enterprise's
saucer, giving us an overall length of about 110m.
Two years later, the High Command seems to have pulled some of
these vessels off the mothballs for low-grade duty, as we see them in the
Vulcan trilogy in ENT: "Awakening"
and "Kir'Shara". I previously believed there were some
modifications to the CGI model, but it is the same that was in
"Fusion". Two of these small

and Archer spot a diagram of this vessel on the display device in
Daniels's quarters in ENT: "Future Tense". Considering the similarity to the Surak class, it
shouldn't be commissioned too far into the future. A label on the display, close to the depiction of
the ship, reads: "RetroFitted Dorsal Carrier, Design XRT-55D, Commission Date 3125".
This doesn't make much sense, and it could refer to anything else on
the chaotic screen.
