Star Trek: Phase II

Phase II told an alternate version of the events of Captain Kirk's second five-year mission aboard the refurbished USS Enterprise (NCC-1701).

Overview
In this continuity, the Enterprise was refitted into a different configuration than seen in. Warp engines, support pylons, and the interconnecting strut appeared to have the most differences. The primary hull closely resembled its pre-refit design, although there were two turbolifts connected to the bridge.

Regarding the crew complement, Most of Kirk’s senior staff from his first five-year mission returned. However, Lieutenant Xon replaced Commander Spock as science officer. Commander Willard Decker served aboard the ship as executive officer. Lieutenant Ilia served as the ship’s navigator. In this version of events, Decker and Ilia survived their encounter with V’Ger in 2273 and continued to serve aboard the ship. 

Uniforms were nearly identical to the Starfleet uniform (2265-2270). A thin stripe matching the shirt color ran through the middle of the black collar. The insignia was the same as in the Starfleet uniform (early 2270s). Female security officers wore pants and a shirt with a tight collar. Ilia wore a short-sleeved gold shirt. 

Media
Star Trek: Phase II was an unproduced TV series developed in the late 1970s. Its pilot script, In Thy Image, was adapted to become the script for when Paramount chose to produce a major motion picture instead of a TV series. The first half-season of episodes had been prepared for the TV series. Complete scripts for In Thy Image and The Child were published, along with detailed summaries of the other episodes.
