I saw a lot of names, canon, and not canon, I know there is constitution and sovereign class, it can have names of locations of earth.
Lower decks ship is the Cerritos, which is a "California" class, together with other ones which I presume have name cities or provinces of that state, but since Lower Decks is more comedy, I start to have doubts about the true canon name and ranks of each ship, since the fanpages and wikis put ships which are doubtly canon.
Most of the time are just names like Rio Grande, but I think that was a shuttlecraft or a runabout.
So still, I don't get the criteria of ranks of names for the ships in general.
This are the kind of doubts I have when I try to understand things related with the lore.
EDIT: So, reading a bit, historically aircraft carrier enterprise was class Nimitz because, well, they like the name, so I can give an idea how can work in Star Trek. I didn't know ships have "class" and random names, I always thought it was more logically choosen. Like, they make 10 ships which are from one class, and given with a name for each one, probably throwing a bottle on it.
Sumarise: Now I know ships has random names and class with all similar ships, but class is not equal of ranks or something. Like hierarchy, that's why I didn't get it.
I didn't know all of this before posting this.
I notice california class was a joke, that's why I ask how much is canon in general.
I look that Zhenzhou and is "Walker-class" what does class means? At least Crazy horse is from the original series, so maybe was a time of brainstorming.
It's all based on navies here on Earth. They chose the language to make certain ships this-or-that class. There are no definitive rules so far as I'm aware. A certain class of submarines would be designated something class because they shared the same weapons or the same propulsion system. So when sci-fi writers picked up this ball they played fast and loose with already fast and loose rules.
You may need to clarify what you mean by canon in this context exactly. If this Walker class appeared in a live action TV show I would say it's canon. If it's in a novel or an animated show I'd say it's not or not necessarily. Trekkies can spend weeks debating this sort of thing.
So, reading a bit yesterday and reading your comment now, historically aircraft carrier enterprise was class Nimitz because, well, they like the name, so I can give an idea how can work in Star Trek. I didn't know ships have "class" and random names, I always thought it was more logically choosen.
