- For the Earthfleet of the alternate timeline in which Khan Noonien Singh won the Eugenics Wars, see: Earthfleet.
The Federation formed in the 22nd century without Earth as a member and considered it an outlaw world. In the 23rd century, Spock's human side prompted him to join Earthfleet. One of the ships in the fleet was the USS Enterprise (NCC-2101). Missions appeared to be profit-motivated, and officers saluted by raising right arms upward with fists clenched.
Male officers wore orange blazers with wide lapels over black shirts tucked into dark blue slacks. Security officers wore a yellow uniform shirt and dark blue pants. Female officers wore a maroon striped dress with short sleeves, with an optional orange tunic underneath. (TOS comic: "No Time Like the Past")
