Introduced in June 2158, the Minotaur fighter and the M/AM-powered Yorktown Class carrier were an attempt to overcome the operational limitations of early M/AM ships by combining the speed and range M/AM-powered warp flight with the maneuverability of high-impulse fighters. Yorktown was based on the Pioneer class cruiser, which had entered service in 2154 and had itself been developed from the Bison-class transport. YORKTOWN carried a new M/AM reactor and four paired EFTL-7A warp nacelles. The impulse drive and its fusion reactor were moved to the extreme stern.

At the front of the cylindrical hull, which had been lengthened by some 20 m, were the ship’s sensors and navigational deflector, as well as command centers, the computer core, crew facilities, and life-support machinery. In the center section were docking cradles for 5 Minotaur long-range fighters. In the aft section were auxiliary deuterium tanks, the missile room, and support facilities for the fighters. With a displacement of some 670,000 tons, Yorktown was by far the largest Earth-designed warship produced to that time and would not be surpassed until the Ambassador class was launched in the 2330s.

After the war, many Yorktowns were converted to fast transports and tankers or sold

The YORKTOWN-class carrier UES SARATOGA and the MINOTAUR fighter Gwendoline are now on display at the Starfleet Museum.
