Background information 
The Inquiry class was identified by name by Michael Chabon. He identified the class as "a heavy cruiser: the Inquiry-class. That's the Zheng He." Originally, when asked by fans on his Instagram account, he identified the USS Zheng He as a  ship, but he later amended the classification of the ship. 

According to the Star Trek Universe collection gift issue 6 magazine (pp. 6-7), three additional starships were named and may have been among those that appeared in the class' first appearance: , , . While not confirmed in canon, all contents therein is compiled from valid background information provided by the production staff. The Zheng He, Toussaint, Varian Fry and Maui incidentally, each received its own individual model/magazine outing in the collection, as a regular, gift, and two bonus issues respectively. The latter three vessels may well have been part of Riker's fleet in "Et in Arcadia Ego, Part 2", as class designer John Eaves is known to habitually provide his producers with additional back-up names/registries when requested to come up with one. It is for this reason that the USS Inquiry is not listed here, as no mention of this vessel was made in the Universe publications.

CGI model 

The class was designed by John Eaves, who in turn based it off one of the three starship designs he had originally submitted for Perpetual Entertainment's ultimately abandoned 2007 version of the  computer game. (Star Trek Universe: The Official Starships Collection, issue 2, p. 9) Eaves' designs were not labeled with names or registries, but he was asked at the eleventh hour to submit one endowed with the name Zheng He and a corresponding registry, which Eaves decided upon as "NCC-86505", even though they remained indiscernable on the production-used CGI model (constructed in  at Pixomondo by Tobias Richter ) as seen onscreen in the episode. (Star Trek Universe: The Official Starships Collection, issue 2, p. 14)

A publication version of the model became prominently featured in several issues of the Star Trek Universe: The Official Starships Collection, the first of which released in the Spring of 2021 and each accompanied by a physical display model based off the production CGI model. The model had to be re-rendered in , as that was the software package of choice for the publisher of the publication, Eaglemoss Collections. The re-rendering was done by publisher mainstay Fabio Passaro, who also created the corresponding  files needed for the construction of the master from which the display models were produced. After its debut in the Universe publication, the publication version became also prominently featured in the August 2021 second edition of the Star Trek: Shipyards - Starfleet Ships 2294 to the Future reference book.

Apocrypha 
The (current) Star Trek Online game features the  as the class-vessel. The notion was also adopted in the Shipyards - Starfleet Ships 2294 to the Future second edition book.
