"Right now I'm on the bridge of the toughest, fastest, most powerful ship Starfleet ever put into service."
The USS Zheng He (NCC-86505) was an Inquiry-class Federation starship operated by Starfleet in the late 24th and early 25th centuries.
In 2399, the Zheng He was commanded by Acting Captain William T. Riker at the head of a fleet of ships tasked to help defend Coppelius from Zhat Vash forces. (PIC: "Et in Arcadia Ego, Part 2")
In 2401, Starfleet Academy cadet Sstefaan Treereko was assigned to the Zheng He. The ship subsequently joined a Starfleet armada assembled to oppose the massive Singularity that emerged from a spatial anomaly. It was briefly compromised when the Borg Queen began assimilating the USS Stargazer and obtained its command codes. After an understanding was reached with the Queen, the Zheng He joined the Borg in a coordinated effort to deflect a massive energy burst from a newly forming transwarp conduit.

The ship was presumably named for the fifteenth century Ming Dynasty Chinese admiral and court eunuch Zheng He. The bridge set was a redress of the USS Discovery bridge set. 
For the Star Trek: Picard Official Starship Collection from Eaglemoss Collections, the USS Zheng He has been assigned the registry number NCC-86505. 
The appearance of this ship in "The Star Gazer" was confirmed by Dave Blass. 
This ship was listed, with other spacecraft, under "Assignment" on a PADD used by a Starfleet Academy officer. This PADD is seen in the The Ready Room episode "Mercy".
