(written from a Production point of view)
This ship was identified by a Constitution-class icon in two display panels created for Star Trek IV: The Voyage Home. Two unnamed Constitution-class ships are seen docked at the Spacedock at the end of the film. It was assumed this ship was one of them. The panels were not clearly visible on screen in any scene of the final release. These two panels show NX-2000 and the NCC-1707 departure routes from the Spacedock. One of the panels abbreviated the registries to NX-200 and NC-177. It was possible these graphics were created to correspond with dialogue from a deleted scene found in the shooting script for the two dock controllers: "Excelsior and Intrepid are cleared to depart. Open spacedock doors" followed by the failure of both ships to power up and the doors to open, due to influence by the Whale Probe.
Star Fleet Technical Manual stated the registry NCC-1707 belonged to USS Hood. This would contradict the registry NCC-1703 given for that ship in the 2008 remastered version of "The Ultimate Computer".
