1. Ships of the Luna class appear in PIC: "The Star Gazer" and "Farewell". As many as 36(!) Luna-class ships are part of the doomed fleet in PIC: "Vox" and "The Last Generation".
2. The Luna 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. Although often otherwise stated, the design was non-canon until its appearance on Lower Decks.
3. The name "Luna class" is official since LOW: "An Embarrassment of Dooplers". All ships are named for moons in the Sol system.

1. No ship of this class was ever visible. The class name and individual ship name come from a TNG Okudagram labeled "Starfleet Operations". Actually, there are two versions of this display, of which one lists the Trieste NCC-37124 as a member of the "Yosemite class". According to the Star Trek Encyclopedia II, the one with "Merced class" is correct though.
2. A model of the USS Trieste was built for use on DS9, a kitbash consisting of a Miranda-class saucer and Galaxy-class nacelles. The registry was shortened to NCC-3724. This model probably didn't make it to the screen.

1. The original Miranda (USS Reliant) was designed by Mike Minor and Joe Jennings for "Star Trek II" and built at ILM. It appeared in many episodes of TNG and DS9, set almost 100 years later.
2. The two modified versions seem to be far less common, since the only known ships of these subclasses are the Lantree in TNG: "Unnatural Selection" (Miranda II) and the second Saratoga in DS9: "Emissary" (Miranda III), respectively. Demoted to a transport ship, the Lantree apparently does not need the weapons in the rollbar any more. The actual reason is that Gary Hutzel didn't get the lighting of the rollbar to work when he prepared the model for shooting, and decided that the ship would still look good without it, thereby "inventing" the sub-class. The Saratoga can be seen firing phasers from the sensor dome (like the TOS Constitution). Maybe we should discount this as an VFX error.
3. The more recent Mirandas in Dominion War have nacelles visually identical to the ones of the USS Reliant and all other standard Mirandas before, but they are lighted like on newer Starfleet ships, with red Bussard collectors and blue warp field grilles. This could point to a refit of the ship and might explain why these old ships are still in service. It is not evident, however, if the 24th century Miranda is really faster. All we can say is that the ships are cannon fodder, considering how fast most vessels of this class are obliterated in DS9: "Sacrifice of Angels" and once again in the stock footage shown in DS9: "What You Leave Behind". The area of the aft torpedo tubes in the pod are lighted on some of the Dominion War Mirandas like the impulse engines below in the main hull. If we don't want to discount this as an error, these Mirandas constitute yet another variant.
4. Though frequently otherwise stated in the Star Trek Encyclopedias, the Brattain has a rollbar, as can be clearly seen in TNG: "Night Terrors". The ship is named for Walter Brattain, the co-inventor of the transistor. The model, however, was mislabeled as "Brittain".
5. Which one was first, the Miranda or rather the Constitution refit? There are several possibilities.
6. The Miranda class is often called "Avenger class" in fandom. As long as any canon evidence is missing, I go with the name stated in the Star Trek Encyclopedia. Other class names listed there were not on screen either, but are commonly accepted.
7. The USS Trial appeared in DS9: "The Way of the Warrior" as a part of the task force led by the Venture. Model photo (AMT/Ertl kit) courtesy of Larry Nemecek. Note that "RELIANT" was simply rearranged to "TRIAL" and "1864" to "1948".
8. The registry NCC-1864 of the Reliant (without the name) can be seen as soon as on the wall chart in TOS: "Court Martial".
9. The actual registry of the Saratoga from "Star Trek IV" is NCC-1887 and can be clearly seen in the Drex TV episode 4, unlike everything ever stated before.
10. According to the deployment status display in TNG: "The Measure of a Man" there is a Saratoga with the registry NCC-31640 (or similar). This is overruled by the hull number NCC-31911 visible on Sisko's ship in DS9: "Emissary", unless we make up another complicated history of ships being renamed.
11. A ship of the class in the same configuration as the destroyed USS Saratoga NCC-31911 is on display at the Fleet Museum, as seen in PIC: "The Bounty". This is explained in the museum file as follows: "This exhibit features the USS Saratoga NCC-1887 which was salvaged and restored to replicate the USS Saratoga NCC-31911 which was destroyed at the Battle of Wolf 359. The exhibit features restored sections of both eras of Miranda class ships."

1. The Nebula prototypes were designed and built by Ed Miarecki. His basic design was developed into a fully-fledged ship by Rick Sternbach and Mike Okuda, which first appeared as the USS Phoenix in TNG: "The Wounded".
2. There are at least four variants of the fully-fledged Nebula design. Only the Phoenix could be seen with the different (and less detailed) sensor pod than on later Nebula-class ships. The Sutherland of TNG: "Redemption" was the first ship with the triangular pod, followed by a slightly different variant, the USS Farragut from "Star Trek Generations".
3. There is at least one CG version by Digital Muse as in VOY: "Message in a Bottle" and "Endgame" (Bonchune variant). A Nebula CGI seen in DS9: "The Changing Face of Evil" seems to have a very strange cone-shaped saucer. I think it is just an inaccurate rendering, not still another variant. Read everything about the variants here.
4. Older drawings of the Nebula class from the Encyclopedias show the saucer of the standard Nebula with the same diameter as that of the Galaxy, while the top half is flattened (and therefore has fewer decks). The saucer of the Nebula studio model, however, seems to have exactly the same height, only all the windows on the decks 6-9 are removed compared to the Galaxy model. The CGI featured in VOY: "Message in a Bottle" even includes all the missing windows.
5. The Nebula prototype II appeared as "USS Melbourne NCC-62043" in TNG: "The Best of Both Worlds II", but its name and registry were not readable. The very same name and registry were visible on the Excelsior in DS9: "Emissary", however. Prototype I appeared in TNG: "Future Imperfect", and it was modified to with a pod to become No. III in Sisko's ready room on DS9. The depictions of model I and III may not be quite correct, as we only have screen caps as references. Read everything about the Nebula study models and about the naming conflict.
6. In TNG: "Interface" Geordi says the USS Hera has a crew complement of more than 300, although there should be considerably more on a ship of this size. Maybe it was running with a minimum complement at the time. The same may apply to the Prometheus in DS9: "Second Sight" where there seemed to be neither a captain nor a first officer.
7. The NCC-6xxxx registries of some Nebula-class ships suggest that the class has been introduced some years prior to the Galaxy class if the ships are sequentially numbered.
8. "Bellerophon" is the correct spelling of the ancient Greek hero, although the ship is sometimes listed as "Bellerephon". The ship seen in DS9: "Emissary" might have been incorrectly labeled, but it was not readable, and the later Intrepid-class ship was definitely "Bellerophon".
9. The non-canon Ships of the Line calendar shows a Nebula-class vessel USS Bonchune NCC-70915 (after Rob Bonchune of Foundation Imaging). The same CGI may have appeared in VOY: "Message in a Bottle", and at least its number was finally legible in VOY: "Endgame".
10. One ship of the class, the USS Lexington, can be seen at the Fleet Museum in PIC: "The Bounty". Instead of NCC-61832 as in all editions of the Star Trek Encyclopedia, this ship has the registry NCC-30405, which is way off but is apparently what appeared on the (illegible) status chart in TNG: "The Measure of a Man".

1. The ship was built by Greg Jein for TNG: "The Best of Both Worlds II". The official diagram from the Star Trek Fact Files is not very precise. It reproduces the overall structure, but lets it look like an awful kitbash job. Actually, the model was scratch-built by Greg Jein but it uses three way too large nacelles. We have tried to correct at least the most blatant errors.
2. Reviewing the Wolf 359 graveyard scene, the Niagara is the rather prominent vertical ship when the Enterprise is shown entering the debris field.
3. The registry of the Princeton is NCC-59804, as can be seen on the model itself. The Star Trek Fact Files and the Star Trek Encyclopedia II (individual entry) give NCC-58904. The registry NCC-33821 for the Wellington comes from the deployment status chart in TNG: "The Measure of a Man", as opposed to the NCC-28473 as listed in the Encyclopedia.

1. Contrary to all rumors the Norway class appeared exclusively in "First Contact" (except for a few indirect appearances on displays). There was only a rather poorly detailed CGI by ILM of the ship, not a real studio model. At some point, the mesh of the Norway was purportedly irretrievably lost, and we never saw it again. Ironically, the DS9TM lists the ship as part of the task force to retake Deep Space 9, though.
2. The unusual phaser cannon of the Norway is reminiscent of the cannon the alternate Enterprise-D possessed in "All Good Things". For the reconstruction in the Official Starships Collection, the ship was given standard phaser strips that were not on the original CG model.
3. The length of 355m is based on the ILM size chart, with the assumption that all other Starfleet vessels were scaled down by 0.88 relative to the Sovereign.

1. According to the TNG Technical Manual the Galaxy class was supposed to be replaced by a new capital ship type called "Nova class". The producers of Star Trek Voyager, however, decided to give this name to a small type of science vessel in VOY: "Equinox" instead.
2. The design of the Nova class is derived from the Defiant pathfinder design, whose top view is depicted in the DS9 Technical Manual.
3. The future Nova variant could be seen in VOY: "Endgame", the obvious modifications being that the deflector gap in the saucer was largely filled, there was a new bridge or bridge dome, and the fins on the nacelles had been tone down. I assume that, although the future has been altered, the variant actually exists. At least the USS Rhode Island, with its registry from the early 2370s, must already have been built, with or without the modifications.
4. The direct comparison of Voyager and Equinox MSDs in VOY: "Equinox" shows the latter at only 150m, less than half the length of the Intrepid-class ship. Fitting the eight decks into the Nova class, with about the same deck heights as on Voyager (3.5m to 4m), would require a length of at least 180m. Considering that the Equinox used largely the same internal sets as Voyager. Rick Sternbach gives the design length as 221m, although this would make the decks very tall. The Rhode Island in VOY: "Endgame" is way off scale, as it seems to be at least half as long as the Klingon Negh'Var variants. Either the VFX people had no idea of the Klingon vessel, or they unwisely decided to let the Rhode Island, fighting against two of them, appear more powerful.
5. 20 ships of this class appeared in the ill-fated fleet in PIC: "Vox" and "The Last Generation".

1. The USS Grissom was built at ILM for "Star Trek III". It is unlikely that the Oberth class is a much older design than the Excelsior class (see starship class inconsistencies), although the registries suggest so. In any case, the Oberth class has been very successful, since production continued for at least 80 years. I don't think that we should predate the whole class by several more decades.
2. Curiously, only three of the various ships of the class we could see in live action Trek were not destroyed: the Biko, Copernicus and Cochrane. It is a miracle the design lasted as long as it did!
3. The USS Grissom most likely has weapons in "Star Trek III". Kirk, who is probably aware of the ship's class, wonders whether the Captain Esteban of the Grissom will fire at the renegade Enterprise. The simple explanation why the ship is destroyed so quickly nonetheless may be that there is no time to raise the shields, and that the Klingons target the impulse engines and thereby hit the warp plasma conduits.
4. There is one Oberth-class ship at Wolf 359, and the class is present at the Sector 001 battle in "First Contact" too. These vessels may have been equipped with state-of-the-art weapons in the meantime. But the USS Bonestell, as seen in DS9: "Emissary", may have entered the battle area accidentally. Although this was never the writer's intention, it may have been the transport ship that was to rendezvous another ship at Wolf 359, as mentioned in VOY: "Infinite Regress". In this episode, Seven is possessed by the personalities of several assimilated individuals, among them a mother who was to meet her son, a Starfleet member, at Wolf 359.
5. The Star Trek Encyclopedia lists the Biko as Olympic class, but TNG: "A Fistful of Datas" clearly shows an Oberth-class vessel.
6. The registry of the Raman is given as NCC-59983 in the Encyclopedia, but NCC-29487 is clearly perceptible on a display in TNG: "Interface".
7. The registry NCC-640 of the Copernicus can be identified in "Star Trek IV". The model was not relabeled for its next appearance in TNG: "The Naked Now", so the Tsiolkovsky has the hull registry "NCC-640" (barely legible) too, although the dedication plaque reads NCC-53911. For TNG-R the hull registry was accordingly fixed to NCC-53911, but only in some shots.

1. The most prominent ship of the class is clearly the USS Enterprise NCC-1701-F. The ship is scheduled for decommission for some unknown reason (although the class is fairly new) as shown on a display in PIC: "The Next Generation". We can see see the Enterprise lead the fleet under the command of Admiral Shelby in PIC: "Vox". As many as 13 ships of the class appear in "Vox" and in "The Last Generation".
2. The class was originally designed for Star Trek Online, including the particular ship USS Enterprise-F. For Star Trek Picard, the design was slightly modified, which is most noticeable in the curvature of the nacelles. The game version also features multi-vector attack mode and includes an auxiliary craft (Aquarius class) that may not be part of the PIC design.
3. Length of the Odyssey class according to the official Picard season 3 scale chart. Disregarding outliers from the Abramsverse, this is the by far longest canon Starfleet ship class (whereas Galaxy/Ross and Nebula/Sutherland are the same order of size in terms of internal volume).

1. The Olympic-class USS Pasteur was built by Bill George as a homage to the earliest sketches of the original Enterprise by Matt Jefferies. It is a free-style interpretation of this original design and retains just the spherical main hull, while the Daedalus closely follows Jefferies's concept. The side view here at EAS is taken from the Star Trek Fact Files and is much closer to the studio model than the one from the Encyclopedia II.
2. The widespread idea that the Olympic class may be derived from the Daedalus class is only bad fan speculation. In engineering, very different design considerations may easily lead to the same shape if it is a simple shape. The two ships have absolutely nothing in common except for the spherical main hull (just as all Enterprises have saucer-shaped main hulls). I could well imagine that a variant or sister design of the Olympic comes with a traditional saucer, which would ultimately invalidate the idea of a Daedalus-Olympic lineage.
3. The Olympic class was only shown in the parallel reality in TNG: "All Good Things". However, the USS Nobel is evidence that the class exists in the "real" universe as well. Since the registry of the Pasteur is not higher than "present" registries, it can be supposed that the individual ship is legit too.
4. Mike Okuda initially christened the ship design "Hope class", as the dedication plaque of the Pasteur shows. The model was labor of love for Bill George, and he named his ship Olympic class. When it was used for the episode, it needed to become the USS Pasteur, and Mike Okuda changed the class name to Olympic out of respect for Bill George. Since the Star Trek Encyclopedia II the design is consistently listed as "Olympic class". The number NCC-58925 on the model does not comply with the NCC-58928 on the plaque either. It is evident that the clearly readable hull number supersedes the one on the obscure plaque.
5. The ship class finally shows up in the "real" 24th century in LOW: "Cupid's Errant Arrow".

1. The USS Voyager NCC-74656-B of this class can be seen on a display in PIC: "The Next Generation". 36(!) ships of the class appear in the doomed fleet in PIC: "Vox" and "The Last Generation".
2. This class was designed for Star Trek Online. In-game, it is a further development of the Intrepid class. It too has pivoted warp nacelles, which are down when at rest or at sublight speed and horizontal at warp.
3. Length of the ship according to the official Picard season 3 scale chart.
4. Since this is already the Voyager-B, the Voyager-A (whose existence was teased in PRO: "Supernova II") must already have been decommissioned.

1. The small Federation fighter, as seen in various DS9 episodes (most prominently in "Sacrifice of Angels"), is listed here and not under the shuttle category because it seems to be capable of independent operation. We have no evidence that the fighters are deployed from carrier ships. The doors on the Akira, the most prominent candidate, seem to be too small for that purpose.
2. In visual effects shots the fighter seems to be 30m long, maybe more. But the cockpit exterior may have been designed with the Type-15 shuttlepod in mind. Actually, the shuttlepod set was used for the interior of the ship in DS9: "The Maquis". 25m is a compromise that wouldn't enlarge the cockpit too much, while giving us a big enough ship.
3. The name "Peregrine" is not certain, but was mentioned for a Maquis fighter type. It is more likely this one than Chakotay's raider.
4. Although frequently otherwise stated, Chakotay's raider (VOY: "The Caretaker") is not a variant of the above presumed Peregrine class. Chakotay's ship has a completely different structure and is much larger, with a crew of at least 40. It is not known if this design is also employed by Starfleet.
5. One of the most embarrassing flaws of the Star Trek Encyclopedia II can be found on the very first page where a Peregrine-class ship is depicted, but labeled as "Academy trainer craft". The error evidently occurred as soon as the image was created, since the ship carries the Federation and Academy emblems. Unfortunately the depiction with the wrong label found its way into VOY: "Drone" where we can see the Federation fighter along with several other (correctly labeled) ship diagrams. I have removed the wrong logos in the above image.

1. NX-59650 is seen on the hull in VOY: "Message in a Bottle", whereas the MSD and the dedication plaque are labeled as NX-74913. While the latter registry suits the ship much better, it could never be identified on screen. We might think it would be superseded by the clearly visible hull registry, but there are theories that would allow both numbers to be authentic.
2. The Prometheus has something akin to a landing gear, very similar to Voyager's, visible in the ship's MSD. It is a matter of interpretation how close a look we are allowed to have at the MSD.

The ASRV (autonomous survival and recovery vehicle) may be a novel, substantially upgraded type of lifeboats.

1. The Saber class was first seen in "First Contact". For some time it was not clear whether "Sabre" or "Saber" is the correct spelling. Although I like "Sabre" better, in reverence of the classic F-86 jet fighter, I adopted "Saber" as in an issue of Star Trek: The Magazine.
2. One ship of the class (USS Argo) can be seen on display at the Fleet Museum in PIC: "The Bounty".
3. The image in the Star Trek Encyclopedia II (see above) shows the registry NCC-81947 for the USS Yeager. However, the CG design clearly has a NCC-61947 (both are a clear homage to Chuck Yeager who broke the sound barrier in 1947). In this case it is hard to explain why there is a quite modern ship design with another USS Yeager and a higher registry. Maybe the USS Yeager NCC-61947 was destroyed in the Borg battle of 2373, and the name "Yeager" was reused for the new ship seen at DS9 soon after.
4. While much of the data in the starship section of the DS9TM is already wrong enough, the Saber is listed with exactly the same dimensions as the Norway. The specs in question at least roughly fit the larger Norway, while a length of 365m is way off for the Saber. The length of 223m is based on the ILM size chart, with the assumption that all other Starfleet vessels were scaled down by 0.88 relative to the Sovereign.

1. The Stargazer, commanded by Captain Rios, appeared in PIC: "The Star Gazer" and "Farewell", as the then only ship of its class. But as many 14 ships appeared in the doomed fleet in PIC: "Vox" and "The Last Generation".
2. This class was designed by Dave Blass, Doug Drexler and John Eaves. It has four nacelles to allow a better distinction from the other ships of the fleet and also to insinuate a lineage that includes Picard's old Stargazer of the Constellation class. In the ready room, we can see a model of that ship as well as of the still older Stargazer of the Radiant class, also with four nacelles.
3. According to Seven in PIC: "The Star Gazer", "the Stargazer is the first of a new class of ship", which contradicts naval naming tradition. Perhaps she meant to say that it is the first ship of the class that was enhanced with Borg technology. Either that, or it is not actually the Sagan class, but the Stargazer class.

1. Also designated as "mission scout", this vessel type was prominently featured in "Star Trek: Insurrection", where it was piloted by Data. The CGI apparently has no name printed on the hull. I took the side view in the upper left from the Star Trek Fact Files. Albeit its lines are less elegant, this rendition is more accurate than the one previously published in Star Trek: The Magazine .The latter is probably based on a pre-production sketch, rather than on the final model.

2. Of course, this is the design that appeared as Magee class in Star Trek Discovery. SHO: "Children of Mars" was produced by the same staff as Discovery, which (in addition to being cost-saving) explains the crossover. In order to preserve the status of Picard as unrebooted Star Trek, it is inevitable to disregard the link to Discovery. The assumption that the ship type is relatively new in the late 24th century also removes the two dilemmas to explain why Starfleet would upgrade or even newly build ships whose construction is 150 years old, and why those ships looked too advanced for the pre-TOS era in the first place.

1. The starship was designed for "Star Trek: First Contact" by John Eaves and Herman Zimmerman with support from Rick Sternbach. The stretched appearance is a strong contrast to almost all other classes and is obviously intended to make the Enterprise-E look "fast".
2. Pre-production drawings of the Sovereign class show a saucer separation. In separated mode, the quantum torpedo tube/captain's yacht is still connected to the engineering hull. This configuration is also reproduced in the parts of the AMT/Ertl model kit. It is unlikely, however, that the ship is actually separable.
3. The combination of the quantum torpedo launcher with the captain's yacht is a major design flaw. The torpedoes almost scratch the yacht's windshield. Accelerating the torpedoes in the preferred horizontal direction is impossible, and it is extremely complicated to get them to the launcher, passing the docking area of the yacht.
4. The ship was slightly redesigned for its appearance in "Star Trek Nemesis". A new CGI model (the third one) was built. Aside from additional torpedo emitters and phaser strips, a small adjustment was made to the upper shuttlebay area, where the side walls next to the impulse engines were extended, smoothing the transition from the saucer to the engineering hull. Also, the nacelles were moved slightly forward (3.5%) and upward (1.3%). All these changes were only cosmetic and arguably unnecessary on the model as well as on the real ship. While it would be no problem to replace smaller hull segments on the full-scale Enterprise, I don't think the nacelle assembly would be entirely taken apart for a minor redesign and I tend to ignore this modification on the model (which would also make the ship around 12m shorter if we took them for granted).
5. Considering that the Reman intruders were detected on "deck 29" in "Nemesis", it has been speculated that the engineering hull was extended too. But the shape is still the same, so a potential deck relocation must have been internal. The (pre-Nemesis) MSD, on the other hand, shows 24 decks in an arrangement that would not allow to split them or turn Jefferies tube levels into full decks. The error seems to become even worse if we consider that Riker and the Viceroy go down a Jefferies tube, and then the Viceroy falls down several more decks. But actually, while the order of events creates the impression that this happened on deck 29, we can see a door label "0940" behind the Viceroy, implying that they had already gone all the way up to deck 9.
6. No Sovereign-class vessel except for the Enterprise-E could be seen until as late as 2022 when several ships of the class appeared in PIC: "The Star Gazer" and "Farewell". As silly as it is, the producers did not want to "waste" the then new ship design in DS9 or Voyager, but exclusively reserve it for the big screen. Finally, as many as 38(!) Sovereign-class ships were part of the doomed fleet in PIC: "Vox" and "The Last Generation".
7. The registry of the USS Sovereign may be NCC-75000, as more or less approved of by Mike Okuda. On the other hand, the games Star Trek Bridge Commander and Star Trek Legacy both use NCC-73811 as the Sovereign's registry.

1. The USS Chekov was built by Ed Miarecki and could be seen only faintly in the Wolf 359 graveyard scene. Michael Okuda describes the ship as a scaled-down Galaxy saucer with engineering hull and two marker nacelles. The underslung pod seems to be taken from the Galaxy class.
2. Since the name Chekov (without the usual "h" as in Chekhov) is uncommon, we can suppose that Pavel has gained much appreciation in Starfleet. The registry of the Chekov is actually NCC-57302.

1. The Steamrunner class first appeared in "First Contact" and only exists as a (comparably poorly detailed) CGI. We may infer from the registry of the Appalacia that it is not among the most recent starship classes, although its design looks quite modern and has several design features in common with the Sovereign class, e.g. the hull plating and the escape pods. The class name is information from behind the scenes.
2. The length of the ship is based on the assumption that the lifeboats are the same type as on the Sovereign, and indirectly on the ILM size chart.
3. On the size chart, the Hiroshima has the number NCC-52136, but this one was eventually placed one the Appalacia CGI model.

1. Ships of this class appeared in PIC: "The Star Gazer" and "Farewell". The USS Chandrasekhar and USS Hypatia were visible in PIC: "The Next Generation".
2. The Sutherland class was designed and modeled by Thomas Marrone for Star Trek Online. Like the Nebula, it is equippable with a mission pod.
3. The Sutherland, however, is not a variation of the Nebula class (at least not in canon Trek) because the dimensions and proportions are too different.

1. This class is often mistakenly classified as runabout, but it is definitely much larger than e.g. a Danube class. The studio model was originally used for an orbital shuttle, but substantially modified with Constitution and Miranda components in a fashion to look like a "real" starship with several decks. There is no way it could be in any way related to a runabout.
2. "USS Jenolan" is the correct spelling (after the Jenolan Caves in New South Wales), although the older Encyclopedias call it "Jenolen" and the model was labeled "Jenolin".
3. The USS Nash is the ship that could be frequently spotted at Deep Space 9 since the fifth season. In the VFX shots the ship was turned upside down, probably to indicate it might be of another, perhaps smaller type. Nevertheless, there is no reason to believe this is actually the case. The silly registry NCC-2010-5 of the Nash should be ignored.

1. The Wallenberg class can be seen in large numbers as footage in PIC: "Remembrace" and for real in the flashback in PIC: "Maps and Legends". We can recognize the word "TUG" on the upper aft hull.
2. The class name can be inferred from a statement of the former Romulan senator in PIC: "Absolute Candor". Michael Chabon confirmed that the ships seen on screen are indeed the mentioned Wallenberg class. Raoul Wallenberg is famous for saving thousands of Jews from the Nazis in Hungary and disappeared mysteriously during the following Soviet occupation.

1. No ship of this class was ever visible. The class name Wambundu is from the Star Trek Encyclopedia; only the two individual ships were mentioned on screen.
2. It can be conjectured that a number of Wambundu-class ships, which do not meet the requirements of a light cruiser any more, have been reassigned as medical transports such as the USS Fleming. Clearly the statement of the fake Captain Paul Rice in TNG: "Arsenal of Freedom" that the Drake was only capable of Warp 2 is nonsense, just as Riker's answer that his ship was the "USS Lollipop".

1. In TOS: "The Ultimate Computer", the ore freighter Woden that gets destroyed by M-5 looks like Khan's ancient DY-100 class because the same model was used. The Woden has to be a more recent ship, however. The DY-100 did not have warp or only impulse drive, and it is highly unlikely that the design might be of any use by 2268, least of all in interstellar space. Most likely all ships of this class, save for the Botany Bay, did not even survive the Eugenics Wars and the Third World War anyway.
2. In TOS-R the unfitting vessel was replaced with the cargo drone from TAS. The TAS design had previously been adapted to serve as the USS Antares in TOS-R: "Charlie X", but there with a new crew section that was omitted for the Woden. The registry is NCC-325, indicating that the Woden is a Starfleet freighter and numbered in the same fashion as a "real" manned ship. This is consistent with Spock's statement that the Woden is "listed in Starfleet Registry as an old-style ore freighter converted to automation".

1. The Yeager was visible in stock footage of ships in no less than 24 DS9 episodes. It is a kitbashed design, which incorporates components of the Intrepid and Maquis raider in an impossible combination. Even the weapons and other protrusions of the Maquis model were retained. The "official" image in the DS9 Technical Manual reproduces the look of the model basically correctly, except that the nacelles should be tilted, as they are glued directly to the "wings" of the Maquis raider.
2. Until recently we believed that Yeager was the class designation, and not the name of the individual ship. This would have allowed to reconcile this Yeager with the USS Yeager NCC-61947 of the Saber class that could be seen in "First Contact". Now the situation is different, as we are left with two Yeagers with very close registries. Even if the Yeager in DS9 had been named in honor of the ship that may have been destroyed by the Borg, this would still raise the question why the new ship has such a low registry (while other newly commissioned ships of the time are around NCC-75000).

1. No ship of this class was ever visible. The class name Zodiac is from the Star Trek Encyclopedia.
2. It is not clear whether this starship class really exists, since the Yorktown comes from Q's projected future in TNG: "All Good Things". Anyway, we may presuppose that Q's future would not fabricate facts that can be refuted already in the present, such as a ship with a registry from the 2350s or 2360s. Furthermore, a USS Yorktown was talked about in TNG: "Frame of Mind", which may easily be the Zodiac-class ship of this name.
