PRE-TOS Yorktown Class

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. Whereas PIONEER had a large fusion reactor, a single midline Pachyderm III warp nacelle, and two auxiliary directional Jaguar I nacelles, YORKTOWN carried a new SSWR-IIIB M/AM reactor and four paired Jaguar III warp nacelles. The impulse drive and its fusion reactor were moved to the extreme stern. At the front of YORKTOWN\'\'s cylindrical forehull, which had been lengthened by some 20 m, were sensors and the navigational deflector, command centers, the computer core, crew facilities, and life-support machinery. In the center section of the forehull were docking cradles for 5 MINOTAUR long-range fighters. In the aft section of the forehull were auxiliary deuterium tanks, the missile room, and support facilities for the MINOTAUR fighters. With a displacement of some 670,00 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.
In June 2158, the M/AM/fusion-powered MINOTAUR fighter (P/A-33) and the M/AM-powered YORKTOWN carrier (CVM-5) were introduced in an attempt to overcome the operational limitations of early M/AM ships
