A five-year mission was a standard mission duration for Federation starships in the 23rd century. For bigger, faster and more enhanced vessels, ships could perform exploratory missions farther outside Federation space, and not need to dock at a starbase so often.

History and specifics

Five-year missions were usually conducted by larger Federation starships such as the Constitution-class and Excelsior-class.

Between 2245 and 2285, the USS Enterprise (NCC-1701) conducted six five-year missions, most famously under Captain James T. Kirk between 2265 and 2270.

During his career, Robert April commanded four five-year missions. The Enterprise's first one was under his command, and prior to that he conducted three missions in command of the USS Tiberius. (EV comic: "Flesh of My Flesh")

The Federation and Starfleet abandoned five-year missions as of 3189 due to The Burn. (DSC episode: "Die Trying" )

Kelvin timeline

The USS Enterprise under Captain James T. Kirk was the first ship that was given the first five-year mission. However, the five-year mission briefly ended with destruction of the Enterprise at Altamid. The mission would resume after the construction of the USS Enterprise-A.
