The Yorktowns were one of the final classes of capital ships built by the Terran Confederation. They clearly show the design trends that were to dominate naval architecture during the Rule of Man. Armour was becoming more uniformly distributed, the previous high levels of automation had been abandoned, the missile armament was becoming heavier, and the powerful spinal particle accelerator had been replaced by a low powered meson gun.
The first Yorktowns were built during the 9th Interstellar War, and they formed the backbone of the Terran Confederation Navy during the following Nth Interstellar War, with a total of over 300 being built before the end of the War. Production continued after the defeat of the Vilani and they proved highly effective against the Vargr until the Vargr successfully reverse engineered Meson Gun technology.
The most famous example of the class was the Ark Royal. Only the fourth Yorktown to be completed (commissioned in 2273 AD, shortly before the outbreak of the 9th Interstellar War). The Ark Royal's name was forever engraved into the history books when on the 14th September 2299 AD, Admiral Sirikit Chalarak accepted the surrender of the Sirkakirun Adkhar Makrus on her deck, finally bringing to an end the 1700 year old Ziru Sirka. With the end of the wars, the Ark Royal continued in commission until she was finally retired in 2334 AD and placed on permanent display at the Terran Fleet Museum on Dingir. In 2392 AD she was moved to the new capital of the Rule of Man at Hub/Ershur where she remained until the Solomani Rim War. In 1000 Imperial (5518 AD) she was reactivated and moved back to the Solomani Rim. It was intended that the final surrender of the Solomani Confederation should be signed on her decks (which would have been a powerful political symbol). However, with the invasion of Terra in 1002 Imperial, the war ended in a stalemate and the surrender never came. In 1004 Imperial, the Imperial High Command ordered her destruction and in 1005 Imperial she was destroyed by the combined firepower of the Imperial Rim Fleet. It is interesting to note that officer originally assigned to carry out her destruction (Admiral Veras Lepart) choose to resign her commission rather than carry out what she described as "an act of gross vandalism in the guise of petty revenge".
