- The IKS Amar and two other vessels attempted to intercept the V'Ger situated in Klingon space, but were vaporized by an energy cloud, taking the three ships, and their crews, out of existence. (Star Trek: The Motion Picture)
- There is some controversy over the dating of Star Trek: The Motion Picture. The earliest the film could take place is late 2272, based on information from VOY: "Q2", which stated that Kirk's first five-year mission ended in 2270, and information within the film that Kirk had not "logged a single star hour in two-and-a-half years." The latest the film could take place is 2277, since the Star Trek II: The Wrath of Khan-style uniforms were in use by 2278. (TNG: "Cause and Effect"). Pocket Books officially places the film in 2273.
- According to Star Trek: Star Charts, on page 33, Betazed (Beta Zeta V) was admitted into the United Federation of Planets.
