NCC-1697

From Memory Alpha, the free Star Trek reference

NCC-1697 was the registry number of a Federation starship which underwent a layover at Starbase 11 in 2267. The ship's number was seen on a chart indicating the repair status of several vessels. (TOS: "Court Martial")

[edit] Background

This ship was only identified by its hull number. According to the Star Trek Encyclopedia, which is in turn, based on Greg Jein's article The Case of Jonathan Doe Starship, this registry was assigned to the Constitution-class USS Essex.
