The Star Trek Star Fleet Technical Manual (ISBN 0345340744, Ballantine Books 1975, reprinted 1986, 1996, 2006) is a fiction reference book by Franz Joseph Schnaubelt about the workings of Starfleet, a military, exploratory, and diplomatic organization featured in the television series Star Trek.
Although it is fiction, the book is presented as a collection of factual documents describing the 23rd-century Starfleet and United Federation of Planets, sent from the future to the 20th century.
The book was culled for background imagery in the first three Trek films. Elements from the manual that appear on screen include:
* its listings of starship names, adapted for opening-scene backgrounds at the communications outpost in Star Trek: The Motion Picture; * its starship-class schematics, seen in background bridge displays in the Kobayashi Maru test in Star Trek II: The Wrath of Khan; and * its Enterprise plans, used in Star Trek III: The Search for Spock in a monitor display when the seal on Spock's living quarters is broken.
