EventsEdit

V'Ger destroys the Epsilon IX station and incapacitates Earth's defense network before merging with Willard Decker and Ilia and ascending into a higher plane of existence. ^[3]
General Chang founds the Klingon Defense Forces Elite Command Academy on Qo'noS. ^{[citation needed]}
Betazed is admitted into the United Federation of Planets. ^[4]
The Helvans are gripped by madness. ^[5]

stardate 2286.0: The Klingon Empire's F5GB-subclass commando frigate, a variant of the QuD-class bird-of-prey, enters service. In particular, the F5GB was a refit of the F5G-subclass with uprated deflector shields. All F5G frigate vessels would eventually be modified in this manner.^[6]

Promotions and transfersEdit

Admiral James T. Kirk re-assumes command of the USS Enterprise. Despite his rank of rear admiral, Kirk began wearing a uniform with captain's braid. For the duration of his command, he was referred to as both "admiral" and "captain" in everyday address.^[3]
Shortly before receiving his first operational command, Captain Willard Decker is temporarily demoted to commander, and made ship's science officer and first officer. Admiral Kirk required him to begin wearing a uniform with commander's braid for the duration of his command, and referred to him as "commander" in everyday address.^[3]

Admiral Kirk was very specific about demoting Captain Decker to commander and giving himself a nominal demotion to captain in order to facilitate his takeover of command. However, in TOS movie, novelization & comic adaptation: The Voyage Home, no such move is made to demote Captain Spock, who is coincidentally made Kirk's first officer and science officer.

Births and deathsEdit

Commander Sonak and Admiral Lori Ciana die in a transporter accident. ^[3]
Marla McGivers dies on Ceti Alpha V. ^{[citation needed]}
Tasari dies on Yonada. ^[7]

Mirror universeEdit

In the mirror universe, Harry Mudd succeeds John Gill as ruler of the Terran Empire. ^{[citation needed]}
