1. 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".
2. 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.
3. 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.

1. 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.
2. The master systems display with 11 identifiable decks in the saucer hull points to a length of the California class of about 460m. 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.
3. 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".
4. 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.
5. 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.
6. We don't know for sure if the USS San Clemente really exists because it only appears in Mariner's holodeck scenario in LOW: "Crisis Point". If it does, it quite clearly belongs to the California class.

1. 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. It was first pictured in The Sword of Damocles, released in 2007. As such, the Titan was non-canon until its appearance on Lower Decks.
2. 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.
3. Although it was not mentioned on screen, it is a reasonable assumption that the Titan belongs to the Luna class, as proposed by the designer and stated in the novels.

1. 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".
2. 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.

1. 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).
2. The ship is apparently named for Sir William Osler, a Canadian physician. Note that the Osler doesn't seem to have a USS prefix.

1. The USS Vancouver appears in LOW: "Cupid's Errant Arrow", where the illustrious ship literally overshadows the USS Cerritos.
2. It is unusual that the warp pylons apparently contain inhabitable space, as indicated by the windows in this region.
3. 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.

1. The designation "Type 6A" is visible on an LCARS panel inside the shuttle in LOW: "Envoys".
2. The shuttles attached to the Cerritos are all named for California national parks, those on the Vancouver for neighborhoods in Vancouver. 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.

1. Douglas Station appears in LOW: "Second Contact", "Crisis Point" and "No Small Parts".
2. 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.
