A class of large Starfleet vessels of the 2380s suited to major engineering projects, represented by the USS Vancouver and USS Toronto in Star Trek: Lower Decks.
The Parliament class shares the look of the California class but is considerably bigger and better equipped. Its ships are used for large, complicated engineering jobs, and their up-to-date tools are the envy of the crew of the Cerritos.
The USS Vancouver appears in Cupid's Errant Arrow, where it works with the Cerritos to demolish an unstable moon. Tendi and Rutherford are dazzled by its facilities and compete to win a new T-88 diagnostic scanner, only to learn the prize comes with a transfer they do not want. Mariner meanwhile suspects Boimler's girlfriend Barbara Brinson, a Vancouver officer, of being an impostor. A second ship, the USS Toronto, takes part in the talks on Ferenginar in Parth Ferengi's Heart Place.
