The Tikhio Battleship is a 24 km long construct. The Tikhio do not deploy these much but built them in great numbers once, when they entered a relative long period of peace they stopped making more and instead improved those they had by adding more weapons, better engines etc.
The fist Tikhio Battleship was constructed in 13.602.492 -- BM, they utilised them for safeguarding their borders and keep out any hostile threat. Between 13.103.482 -- BM and 12.937.381 -- BM they mass produced this vessel and produced a total of several millions of them. After this period they halted production and decided to improve them with better technology.
The Tikhio never abandoned the spaceyards for constructing them as they believe they would need them again one day.
