Background information

This ship was not mentioned in the movie's dialogue, but was listed in several starship status charts seen on the sets of the film.

USS Helin dedication plaque given to Eleanor Helin

In an issue of Bjo Trimble's Space-Time Continuum, it was mentioned that American astronomer Eleanor F. Helin was given a model of an Oberth-class ship which bore this name. The Palomar Observatory website has a picture of a dedication plaque for the ship, also stating that it was given to Helin "by the Star Trek franchise". It is unclear if a ship model was indeed given as well, or if the reference to a model in Space-Time Continuum is erroneous. [1]

According to a ship list included in the plans, and not seen in the extended cut of the movie, this ship was commanded by R. Brookshire, and the ship was located in Sector 21290.

The ship's captain was named after Rebeca Brookshire, an assistant to the sixth movie's producer Ralph Winter. [2]
