The second ENTERPRISE was also a Constitution-class ship. She was started in 2286.This ship, originally designated U.S.S. Yorktown was redesignated U.S.S. Enterprise and assigned to the command of Capt. James T. Kirk, following an incident in which Kirk and his crew were responsible for saving Earth for the effects of an alien probe (ST IV : TVH). Though Kirk held the rank of Admiral before taking command of NCC-1701-A, he was demoted to Captain for disobeying a direct order from the Star Fleet Commander of the time, Fleet Admiral Morrow. This demotion gave Star Fleet and Kirk the excuse needed to give Kirk command of a starship once again, and the renaming of this ship was considered a gift to Kirk by StarFleet Command. This vessel played a crucial role in the Khitomer Conference of 2293, preventing a group of conspirators from sabotaging the Conference and assasinating President Ra-ghoratrei of the United Federation of Planets and Chancellor Azetbur of the Klingon Empire. The ship was decommissioned along with her command crew after the Conference.
The missions of this ship while under the command of Captain James Tiberius Kirk were the subject of the fifth and sixth Star Trek movies.
