Starfleet Starships

Antares type

General description

The Antares type is a small cargo vessel of the 23rd century.
Article: The Antares Class(es)
Article: Starships in TOS and TOS Remastered

Known ships

(Name unknown) NCC-502

Annotations

In the junkyard in LOW: "Terminal Provocations", we can see a ship based on the TAS cargo drone and the automated freighter Woden from the remastered version of TOS: "The Ultimate Computer". A very similar design, essentially just with an additional crew module, could be seen as the Antares in TOS-R: "Charlie X".
The ship in LOW: "Terminal Provocations" appears to be the same as the automated cargo drone, without the crew module. Yet, we may argue that the module is simply missing. We never see the front side, where the two designs should be distinguishable due to the different placement of the deflector dish. The registry NCC-502 as visible on the ship in "Terminal Provocations" is very close to that of the Antares, NCC-501. This is why I assume it is an Antares-type ship, rather than a cargo drone.
There is a goof in the sequence in which the Drookmani bombard the Cerritos with debris. We can see how the a fragment of an upper hull with the registry NCC-502 breaks apart when it hits the shields of the Cerritos. A little later, the secondary hull of a ship labeled NCC-502 is largely intact again. This certainly doesn't mean there were two ships with the same registry at the same time, although it is possible that one was so labeled to provide spare parts for the other.

Cargo vessel

California

General description

The California class is a support vessel for tasks such as "second contact", salvage operations or engineering support. The design includes a circular saucer, two underslung nacelles and a pod between the nacelles in which the deflector dish is located.

Known ships

USS Alhambra
USS Cerritos NCC-75567
USS Merced NCC-87075
USS Rubidoux NCC-12109
USS Solvang NCC-12101

Annotations

California-class ships have stripes running across the saucer hull that come in three different colors: yellow on the Cerritos, blue on the Merced, red on the Rubidoux and Solvang. While this may have been done primarily to visually distinguish the otherwise mostly identical ships (especially regarding the Cerritos and Merced in LOW: "Moist Vessel"), the real-world reason my be to indicate different primary operational areas of the ships (yellow for engineering, blue for science, red for command). As a further difference, the roughly triangular raised sector behind the bridge is gray on the Cerritos and on the Rubidoux, whereas it is the same color as the stripes on the Merced and on the Solvang.
The master systems display with 11 identifiable decks in the saucer hull points to a length of the California class of around 500m. The shot with the Cerritos and the Titan side by side in LOW: "No Small Parts" confirms that both ships are about the same size. Yet, the window arrangement of the California class as visible from the outside is inconsistent. There are three narrowly spaced window rows in the saucer rim, although there should be only two. This may have led Eaglemoss to list a length of 794m(!) in the book Starfleet Ships: 2294 to the Future. The actual design size has been confirmed by Lower Decks producer Brad Winters to be 535.2m.
The Cerritos looks somewhat different in season 2. A side-by-side comparison of the ship in the opening credits of season 1 and season 2 reveals that some of these apparent changes are due to a different animation style, such as of the hull reflectiveness and the window brightness. Some are trivial, such as the new light illuminating the ship name and registry. The actual changes are a bit more than just cosmetic: indentations added to the upper nacelle aft ends, a more pronounced structure on the bottom of the saucer hull, slight modifications to the uppermost parts of the pylons and the warp field grille, removal of the decorative yellow stripes on the nacelles and, perhaps most importantly, "blue squares" indicating shuttlebays.
We can see Rutherford's very accurate scale model of the Cerritos in LOW: "An Embarrassment of Dooplers".
Although not explicitly stated, it is absolutely certain that the Alhambra is another California-class ship, because of the striking similarities to the Cerritos that confuse T'Ana in LOW: "Veritas".
Apparently all ships of the class are named for towns in California. This, however, makes it unlikely that the lead vessel really is called USS California.
The USS Rubidoux NCC-12109 and USS Solvang NCC-12101, the two ill-fated ships commanded by Captain Dayton, have hull numbers that don't comply with the Starfleet registry scheme and may be real-world in-jokes, perhaps referring to dates.

Class specifications

Length: 535.2m

Constitution

Constitution (refit)

General description

The Constitution class was introduced around 2240. At that time the Constitution class was the fastest and most powerful ship type of the fleet. Starting around 2271, a number of Constitution-class ships have undergone a complete reconstruction that included new warp nacelles, modification of the engineering hull and "neck", enlargement of the saucer section and a new bridge module. The ships may have been decommissioned at the end of the 23rd century, one of them is displayed in the Starfleet Museum.

Known ships

USS Enterprise NCC-1701 (refit 2271)

Annotations

The Enterprise refit from "Star Trek: The Wrath of Khan" appears in the holographic scenario "The Good of the Many" for Rutherford in LOW: "I, Excretus".
The diagram of the ship in the same episode shows the Phase II Enterprise, rather than the version that appeared in the movies. We can identify it by the kink in the nacelle pylon.
Three pictures of the pre-refit Constitution can be seen in the bar in LOW: "An Embarrassment of Dooplers".

Danube

Danube with rollbar

General description

Runabouts are small starships for personnel transport over longer distances than a shuttlecraft. The Danube-class runabouts are equipped with an interchangeable mission module and an optional weapons or sensor pod at the top of the spacecraft. The ships, which have been introduced in 2368, are usually named after rivers on the planet Earth.
Article: Runabouts with Rollbars
Gallery: Other Small Federation Vessels

Known ships

No name given

Annotations

Runabouts appear in LOW: "Where Pleasant Fountains Lie" (to rescue Mariner and Boimler) and in "I, Excretus" (in Boimler's Borg scenario). These runabouts are definitely supposed to be of the Danube class. On both occasions, we see the ship from just one angle, and the superstructure looks a bit odd, not quite as the familiar rollbar would. Although this may be just an inaccuracy, Lower Decks might show a new pod or new variation.
Furthermore, several Danube-class ships can be seen in Mariner's holographic scenario in LOW: "Strange Energies" where they look as we would expect. At least some, if not all of them, have a rollbar.

Intrepid

General description

First introduced around 2370, the Intrepid class is among the fastest starships of the fleet. It features bioneural computer components and a variable geometry warp field which is accomplished with folding warp pylons.
Article: Voyager Inconsistencies

Luna

General description

The Luna class is a top-of-the-line starship with high combat strength. The design consists of a an ovaloid saucer directly attached to an engineering, with two nacelles that align to the bottom of that engineering hull. A sensor or weapons pod sits atop the saucer hull.

Known ships

USS Titan NCC-80102

Annotations

Riker's USS Titan of the Luna class appears in LOW: "No Small Parts", "Strange Energies" and "Kayshon, His Eyes Open".
The USS Titan was designed by Sean Tourangeau. It was the winning entry in a competition to design Riker's ship (as mentioned in "Star Trek Nemesis") for the novel series Star Trek: Titan. The ship was first pictured in The Sword of Damocles, released in 2007. As such, although often otherwise stated, the Titan was non-canon until its appearance on Lower Decks.
The Titan as seen in LOW: "No Small Parts" is the exact design as in the illustrations by Sean Tourangeau. The registry is the same as well. Yet, the animation doesn't get some details right or interprets them very liberally, such as the window placement. This is especially noticeable in the undetailed and windowless saucer rim of the animated version.
The name "Luna class" is official since LOW: "An Embarrassment of Dooplers".

Length: ca. 450m

Miranda

General description

The Miranda class belongs to the same design family as the reconstructed Constitution class. The warp nacelles are attached to the saucer bottom, which is extended at the rear end to hold additional sensor arrays on the top and two shuttlebays. The original version has a photon torpedo tube mounted on a "rollbar".
Article: Miranda Class Variations
Miranda Gallery

Known ships

USS MacDuff NCC-1877

Annotations

The USS MacDuff is a holographic ship in Mariner's probably not quite realistic holoprogram in LOW: "Strange Energies".
The detailing of the hull (as well as the design of the bridge) overall match with how the USS Reliant looked in "Star Trek: The Wrath of Khan". But the holographic ship has more windows in the saucer section, only two rows of windows in the angular superstructure instead of three and a couple of detail changes on the aft sensor platform and the phaser cannons.

Models in the USS Titan observation lounge, as seen in LOW: "Kayshon, His Eyes Open"

We can't clearly identify the four golden models. But the most likely candidates are (from left to right): the Titan rocket used to launch the Phoenix (an obvious choice for even two reasons), a disk-shaped design from an old sketch by Matt Jefferies, a Loknar-class frigate (FASA), the USS Titan.

Nova

General description

The Nova class is a small ship with a crew complement of about 80.
Gallery: Various Starfleet Ships

Known ships

No name given

Annotations

Starfleet officials arrive in a Nova-class ship at the end of LOW: "First First Contact". It is apparently the variation seen in VOY: "Equinox I+II", not the supposed upgrade (USS Rhode Island) in VOY: "Endgame".

Obena

General description

The Obena resembles an Excelsior class but is a distinct and substantially larger ship class.
Article: Size of the Excelsior Class

Known ships

USS Archimedes NCC-83002

Annotations

The Obena-class USS Archimedes promeninently appears in LOW: "First First Contact".
The neck and secondary hull of the Obena class look mostly the same as on the Excelsior class, the striking extension around the main deflector is like on the Enterprise-B sub-class. Many details are different, such as the exact arrangement of windows and the shuttlebays. The saucer with its typical U-shaped superstructure looks much like that of the Excelsior too, but besides some detail changes such as new phaser emitters there are two decisive differences: The saucer is not round but elliptical now (with the major axis in flight direction as on the Sovereign class), and it is clearly larger, as indicated by the three rows of windows in the saucer rim. Three decks in this location on the original Excelsior would be absolutely impossible, and although Lower Decks has a history of window rows not complying with decks (California class!), the additional fact that the saucer shape is wholly different leads to the conclusion that the ship can and should be larger.
The most noticeable difference to the Excelsior class is the different nacelle type. Under the assumption that the nacelles are the same type as on the Sovereign class (note that the connection point to the pylons is the same too), the Obena class would be some 630m long. The three instead of two decks in the saucer rim, on the other hand, would necessitate a length of some 700m.
The title graphic for the holographic scenario "Escape from Spacedock" too shows an Obena class, rather than an Excelsior. We can recognize the sloping nacelle pylons and the extensions around the deflector dish.
The class is named for art director Nollan Obena, according to Mike McMahan.

Oberth

General description

The Oberth class is a very common science vessel design that is used by Starfleet as well as other Federation institutions. Although its first construction dates back at least as long as the Excelsior class, many ships of this class are still in service as of 2381.
Article: Size of the Oberth Class

USS Pegasus NCC-53847

Annotations

A model of an Oberth class (obviously the ill-fated USS Pegasus, we can almost read the registry) is on display in Riker's ready room on the Titan.
One Oberth class can be seen salvaging the ripped off nacelle of the USS Archimedes in LOW: "First First Contact".

The Olympic class is a mid-sized ship with a spherical main hull.
Gallery: Various Starfleet Ships

Known ships

USS Quito

Annotations

The USS Quito as it appears in Mariner's flashback in LOW: "Cupid's Errant Arrow" is a faithful reproduction of the USS Pasteur from TNG: "All Good Things".
So far, the Olympic class was only shown in the parallel reality in TNG: "All Good Things". Lower Decks features the first verifiable appearance of the ship class in the persistent timeline.

Osler type

General description

The Osler is a more or less secret small starship operated by Division 14 of Starfleet. The vessel is dart-shaped and painted black.

Known ships

Osler NX-75300

Annotations

The Osler can be seen in LOW: "Much Ado About Boimler" where the ship emerges from an anomaly. It seems that this is a deliberate cloaking strategy (although an anomaly would raise unnecessary suspicions).
The ship is apparently named for Sir William Osler, a Canadian physician. Note that the Osler doesn't seem to have a USS prefix.

Class specifications

None available

Parliament

General description

The Parliament class is a capital starship of Starfleet in the late 24th century. The design consists of a circular main hull and two nacelles, whose pylons extend all the way down from the top of the saucer hull around its aft edge.

Known ships

USS Vancouver NCC-70492

Annotations

The USS Vancouver appears in LOW: "Cupid's Errant Arrow", where the illustrious ship literally overshadows the USS Cerritos. Another ship of the class can be seen at the end of "First First Contact".
It is unusual that the warp pylons apparently contain inhabitable space, as indicated by the windows in this region.
The master systems display with 9 decks in the saucer hull points to a length of the class of between 500 and 600 meters. Unlike the ship encounter suggests, the Vancouver shouldn't be much larger than the Cerritos if we go by the two MSDs. Also, just as with the attempt to match the structure of the Cerritos with its exterior, there are more windows visible on the hull of the Vancouver than the MSD would permit.
In "An Embarrassment of Dooplers" there are two ships that may have been supposed to be of the Parliament class, but that have substantially different superstructures and nacelle pylons (see "unknown class 4").

Class specifications

Peregrine

General description

The Peregrine class is a small fighter with a crew of one or two and a size only slightly larger than a 20th century fighter aircraft. The design was used by the former Maquis and is also in Starfleet service.

Fighter
Length: approx. 25m

Unnamed class 1	General description This is an apparently smaller ship type with two nacelles directly attached to the saucer hull, and without a visible deflector.	Known ships No name given
	Annotations In LOW: "Second Contact", "Crisis Point" and "No Small Parts", we can see two otherwise identical starship types at Douglas Station, one with the nacelles up and one with the nacelles down. Although in Star Trek all ships (even of different civilizations) traditionally match their orientations, I assume these two are the same design.	Class specifications None available

Unnamed class 2	General description This is an apparently smaller ship type with two nacelles attached to a small engineering hull with a deflector.	Known ships No name given
	Annotations This previously unseen ship can be seen in LOW: "Second Contact", "Crisis Point", "Veritas" and "No Small Parts".	Class specifications None available

Unnamed class 3, visible outside the museum (probably on Vulcan) in LOW: "Veritas"

At least two of the ships look like they are the same Federation design with a saucer and two nacelles. There is no clue whether they are active and parked on landing pads or whether they are on display in the museum.

Unnamed class 4

General description

This is a mid-sized ship type with two nacelles underneath a saucer hull with two pods on its top aft end.

Known ships

No name given

Annotations

Two of these ships can be seen docked at the starbase in LOW: "An Embarrassment of Dooplers".
Although this may have been supposed to be the same design (Parliament class) as the USS Vancouver from "Cupid's Errant Arrow", there are clear differences about the superstructure and the nacelles struts.

Unnamed class 5

General description

This is a very small ship type with a spherical main hull.
Article: Daedalus Class Problems

Known ships

No name given

Annotations

Two of these ships can be seen docked at the starbase in LOW: "An Embarrassment of Dooplers". They are clearly supposed to be Daedalus-class ships.
While we might explain why one museum ship is docked to the (old) station, perhaps permanently, the existence of two Daedaluses would be a stretch. We can't see the ships up close, and there may be detail differences to the Dadalus (that so far never appeared as a "real" ship anyway) besides the illuminated nacelles. So the interpretation is possible that these are two newer ships that resemble the Daedalus.
For what it's worth, the length of just around 100m looks just right for the Daedalus, but only for the too small size of the ship as given in the Star Trek Encyclopedia.

Class specifications

None available

Unnamed class 6	General description This is a comparably small ship type with an elonagted main hull and two underslung nacelles.	Known ships No name given
	Annotations The ship is docked to the station in LOW: "An Embarrassment of Dooplers". It appears in only one short take behind Ensign Barnes, as seen from the bridge of the Cerritos. Just before and just after that, there is no sign of the ship. While this is a clear continuity error, we assume that the type is real.	Class specifications None available

Starfleet Shuttles

Air tram

General description

This is a planetary shuttle used on different planets of the Federation or affiliated with the Federation.

Known shuttles

No name given

Annotations

We can see a vehicle that was clearly inspired by the San Francisco air tram from "Star Trek: The Motion Picture" in front of the gate to the Klingon district in LOW: "Envoys". The air tram also appears on Qualor II in "We'll Always Have Tom Paris".

Class specifications

Length: approx. 13m

Auxiliary craft I	General description This is an auxiliary craft with two engine pods and an additional pod on top. It has a brownish color and is equipped with a tractor beam.	Known shuttles No name given
	Annotations We can spot this craft through the windows of the Cerritos in LOW: "First First Contact". It could be a Lapeerian design but Starfleet likely would not enlist alien help at this time.	Class specifications None available

Auxiliary craft II	General description This is a shuttle-sized auxiliary craft with three or four engine pods.	Known shuttles No name given
	Annotations This small auxiliary craft can be seen between the bigger ships in LOW: "First First Contact".	Class specifications None available

California captain's yacht	General description The design of the California class includes a captain's yacht.	Known shuttles No name given
	Annotations It doesn't make sense why the Cerritos, which is consistently referred to as a low-grade ship, is equipped with something as prestigious as a captain's yacht, seen in LOW: "First First Contact".	Class specifications None available

Cargo shuttle I	General description This appears to be a cargo shuttle of the late 24th century. It is designed to haul cargo containers that are connected to "freight trains".	Known shuttles No name given
	Annotations Several of these shuttles appear on Starbase 25 in LOW: "An Embarrassment of Dooplers" in various locations, most of them inside the cargo bay.	Class specifications None available

Cargo shuttle II	General description This appears to be a cargo shuttle of the late 24th century. It consists of a main body and separate engine pods.	Known shuttles No name given
	Annotations One such shuttle shows up on Starbase 25 in LOW: "An Embarrassment of Dooplers", parked almost next to the small Vulcan ship.	Class specifications None available

Delta Flyer

General description

The Delta Flyer is a large long-range shuttlecraft. The first Delta Flyer was built by the crew of USS Voyager in 2375, using Federation technology with Borg enhancements. The Delta Flyer has extendable warp nacelles, extendable supplemental impulse exhausts and escape pods.
Gallery: Delta Flyer
Article: Size of the Delta Flyer

No name given

Annotations

Several Delta Flyer designs appear in Mariner's holographic scenario in LOW: "Strange Energies". As they are only holographic, there is no need to explain if and how many new Delta Flyers Starfleet may have built after Voyager's return. Yet, there is an actual design based on the Delta Flyer, see "large Starbase 25 shuttle".

Large planetary shuttle	General description This appears to be a shuttle for public transport on Federation or affiliated planets.	Known shuttles No name given
	Annotations We can see the same shuttle type both on Tulgana IV (non-Federation but with strong Federation presence) in LOW: "Envoys" and on Qualor II (Federation) in "We'll Always Have Tom Paris".	Class specifications None available

Large Starbase 25 shuttle	General description The exact purpose of this shuttle is unknown.	Known shuttles No name given
	Annotations This shuttle type seen at Starbase 25 in LOW: "An Embarrassment of Dooplers" incorporates design elements of the Delta Flyer. But I wouldn't go as far as saying it has to be related to, or based on the Delta Flyer.	Class specifications None available

Orbital platform	General description This type of orbital platform is self-propelled, has one deck and features a large cockpit with a panoramic window.	Known shuttles Orbital Platform Gamma
	Annotations In LOW: "Cupid's Errant Arrow", these platforms assist in the controlled destruction of a moon.	Class specifications None available

Sequoia type	General description The Sequoia is a one-off shuttle, composed of the shortened body of a Type 6a and Type 6 nacelles.	Known shuttles Sequoia
	Annotations We can see the four ensigns work on the Sequoia during season 1, until it is used for the suicide mission in LOW: "No Small Parts". It is quite obviously not a shuttle officially assigned to the Cerritos and probably built of parts that would otherwise have been scrapped.	Class specifications None available

Shuttle Number 5 type	General description This is a streamlined design, and could be a (former) Starfleet shuttle.	Known shuttles Shuttle 5
	Annotations We can see this shuttle, among several others, on a landing platform on Qualor II in LOW: "We'll Always Have Tom Paris".	Class specifications None available

Shuttles at Starbase Earhart, as seen in LOW: "We'll Always Have Tom Paris"

These are too small to be identified.

Shuttles on Qualor II, as seen in LOW: "We'll Always Have Tom Paris"

Many of these are too small to be identified. We can recognize the air tram and the large shuttle that both already appeared on Tulgana IV and have separate entries.

Shuttles on Tulgana IV, as seen on the surface and in the air in several regions of the planet in LOW: "Envoys"

Considering that it is probably not a Federation planet, most of the shuttles seem to be of alien origin. Yet, regarding possible Federation designs, there may be several more besides the Type 6, the Galileo 7, the air tram and the large shuttle that are described in separate entries.

Small Starbase 25 shuttle	General description The exact purpose of this shuttle is unknown.	Known shuttles No name given
	Annotations This small rounded shuttle is visible at Starbase 25 in LOW: "An Embarrassment of Dooplers". It is similar to car-like shuttles seen on Earth in Star Trek: Picard.	Class specifications None available

Tug	General description These small support crafts are used for starship construction and repair in the late 24th century.	Known shuttles No name given
	Annotations Two tugs appears when the Cerritos is repaired inside Douglas Station in "No Small Parts". The tug may be an unmanned spacecraft.	Class specifications None available

Redwood (USS Cerritos)
Yosemite (USS Cerritos)

Annotations

The designation "Type 6A" is visible on an LCARS panel inside the shuttle in LOW: "Envoys" and again in "Mugato, Gumato". There is no rationale for the designation Type 6A, as it doesn't look a lot like Type 6.
The Titan shuttle Coltrane continues the fad that shuttles have nacelles reminiscent of their mother ship, rather than a standard type. At least, it is a more subtle resemblance than on the Voyager, let alone the Defiant shuttles.
The shuttles attached to the Cerritos are all named for California national parks, those on the Vancouver for neighborhoods in Vancouver. Riker apparently named the shuttle Coltrane of the USS Titan for jazz musician John Coltrane. An unnamed shuttle of the type appears at the end of LOW: "Much Ado About Boimler" to take Boimler and Tendi back to the Cerritos.

Douglas Station type

General description

This is a huge type of space station. The upper portion of the mushroom-shaped spacedock may house several large starships.

Known stations

Douglas Station

Annotations

Douglas Station appears in LOW: "Second Contact", "Crisis Point" and "No Small Parts". The unnamed station in "First First Contact" looks the same, is in orbit of apparently the same planet and hence is likely Douglas Station as well.
The design of Douglas Station is very similar to, but not quite the same as the familiar Earth Spacedock and its various re-uses. We can see that Douglas Station has some kind of platform on top where the antennae are located. Also, the shapes of the lower sections are somewhat different. Considering the relatively high level of detail in Lower Decks, we may argue that the differences are more than just artistic license.
In LOW: "I, Excretus", we see the original Earth Spacedock from "Star Trek: The Search for Spock" in a holographic sequence.

TOS starbase type (upgraded)

General description

This is an old type of starbase that was originally built in the 23rd century but has been rebuilt and extended ever since.

Known stations

Starbase 25

Annotations

We can see Starbase 25 in LOW: "An Embarrassment of Dooplers".
The design of Starbase 25 dates back to Masao Okazaki's J-Class station. It appeared in its original form in TOS-R: "The Ultimate Computer" and was adapted for the first book of the Star Trek Vanguard novel series by David Mack (with an increased diameter of 849m). The Starbase on Lower Decks was modified with an extra habitat ring. But we can see that the upper cap and the lower docking ring and antenna are still much the same. The size complies with the one given in the fold-out in the novel.

Probes & Satellites

Disaster recorder

General description

The disaster recorder is a type of log buoy of early starships, and is ejected in case of an emergency.

Known probes

No name given

Annotations

The buoy from TOS: "Where No Man Has Gone Before" belongs to Kerner Hauze's collection in LOW: "Kayshon, His Eyes Open".

Subspace relay type II

General description

Largely or fully automated subspace relays serve to amplify subspace signals to achieve a greater communication range.

Known stations

No name given

Annotations

The purpose of the station or satellite seen in LOW: "I, Excretus" is not revealed, but it doesn't seem to be similar to the subspace relay from TNG: "Aquiel" by accident. But instead of the habitat module and the subspace antenna (as described in the TNGTM and reproduced in the TNG episode) on either side, the LOW episode shows a design with two 20th century solar panels (useless in outer space). This error obviously came to pass because whoever drew the subspace relay for Lower Decks was aware that the model of the station originated as the old cryosatellite Birdseye in TNG: "The Neutral Zone". But instead of checking how the modification to the 24th century station looked like, they took the original Birdseye as an unfitting reference.

Earth Vessels

Phoenix

General description

The Phoenix is the first ship built by humans to go faster than light. The Phoenix was launched by Zefram Cochrane's team from an old missile base in Montana, mounted onto a Titan intercontinental missile to reach orbit.

Known ships

Phoenix
Probably no further ships

Annotations

A not quite accurate model of the Phoenix is on display in the bar in LOW: "An Embarrassment of Dooplers".

Class specifications

Warp ship prototype
Length: 35m (launch), 20m (warp ship)
Speed: Warp 1
Launched in 2063

Vulcan Vessels

Sh'vhal type	General description This is a huge Vulcan vessel, which is not built for combat, but is well-armed.	Known ships Sh'vhal
	Annotations The Sh'vhal with its typically Vulcan annular warp drive appears in LOW: "wej Duj". The ship may have been scaled up to an unreasonable size for the dramatic impact. In comparison with the Klingon BoP and the Cerritos the Sh'vhal looks like it is 2 kilometers long!	Class specifications None available

Small Vulcan ship	General description This is a small Vulcan ship, designed to land in shuttlebays or cargo bays.	Known ships No name given
	Annotations The ship can be seen aboard Starbase 25 in "An Embarassment of Dooplers" and is less than 100m long. The design is reminsicent of Vulcan ships of the 22nd century.	Class specifications None available

T'Plana Hath type

General description

The T'Plana Hath was a small survey ship of unknown class with a threefold structure from the 21st century. It was capable of landing on a planet.

Known ships

No name given

Annotations

A ship of the T'Plana Hath type is visible in the museum in LOW: "Veritas". Perhaps this is even the T'Plana herself.

Class specifications

Survey ship
Diameter: approx. 43m

Vulcan warpshuttle

General description

The Vulcan warpshuttle is a design from the 23rd century that is apparently still in use by the year 2380. It consists of a passenger compartment and a warp sled that can be separated to allow the passenger compartment to dock with starships.

Known shuttles

No name given

Annotations

The warpshuttle is hijacked by the team led by Shaxs in LOW: "Veritas".

Class specifications

Length: 48m

Andorian Vessels

Kumari

General description

The Kumari class is an Andorian design from the 22nd century.
Gallery: Major Alien Ships of the 22nd Century

Known ships

No name given

Annotations

One ship docked to the station in LOW: "An Embarrassment of Dooplers" is undeniably a Kumari class, just like Shran's ship on Star Trek Enterprise.
The appearance of a second anachronistic Andorian design in the same episode doesn't exactly help because it rules out the possible interpretation that the Kumari class could be a museum ship.

Class specifications

Length: approx. 360m

Kumari variant	General description This appears to be a variation of the Kumari class from the 22nd century with additional "fins".	Known ships No name given
	Annotations This ship is docked to the station in LOW: "An Embarrassment of Dooplers". It adds to the anachronism of the Kumari class in the same episode.	Class specifications Length: approx. 360m

Other Civilian Vessels

Maquis raider

General description

The Maquis raider is a small and maneuverable ship with moderate armament
Gallery: Various Federation Ships

Known ships

No name given

Annotations

A Maquis raider is docked to the starbase in LOW: "An Embarrassment of Dooplers". It is likely meant to be the better known variant II, the same as Chakotay's ship. The size relative to the other docked vessels looks about right.
Since the Maquis doesn't exist any longer as of 2381, the ship may belong to a different organization or a private owner. As we know from TNG: "Preemptive Strike", the Maquis didn't possess proprietary ship designs (and definitely wouldn't have had the time to build them).

Class specifications

Length: approx. 60m

Unknown Class

USS Bakersfield, mentioned in LOW: "I, Excretus" as being caught in a causality loop

This may be another California-class starship. Is Bakersfield small enough?

USS Illinois, mentioned in LOW: "Moist Vessel" as a previous common posting of Captains Freeman and Durango

USS Oakland, mentioned in LOW: "Much Ado About Boimler" as being commanded by Captain Amina Ramsey

This may well be another California-class starship. Are there any Lower Decks ships not named for Californian cities anyway?

USS Sacramento, mentioned in LOW: "No Small Parts" as an opportunity for a "huge career boost"

This may be another California-class starship, if it were not for the implication of it being a better positioning than the Cerritos.

(Name unknown) NCC-77567, shuttle with this mother ship registry shown in LOW: "Veritas"

Perhaps this is the USS Alhambra, the California-class starship that T'Ana mistakenly boarded in the same episode? The very similar registry fits with the fact that everything and everyone else is nearly the same.

Non-Existent Ships

USS San Clemente, mentioned in "The Rise of Vindicta" in LOW: "Crisis Point"

The USS San Clemente is referred to in Mariner's holodeck scenario and is said to be non-existent. If it existed, it would quite clearly belong to the California class.
