Sissoi Veliky (Russian: Сисой Великий) was a pre-dreadnought battleship built for the Imperial Russian Navy in the 1890s. The ship's construction was marred by organizational, logistical and engineering problems and dragged on for more than five years. She was commissioned in October 1896 with an appalling number of design and construction faults, and only a few of them were fixed during her lifetime. Immediately after sea trials, Sissoi Veliky sailed to the Mediterranean to enforce the naval blockade of Crete during the Greco-Turkish War. On March 15 [O.S. March 3], 1897 she suffered a devastating explosion of the aft gun turret that killed 21 men. After nine months in the docks of Toulon for repairs, the ship sailed to the Far East to reinforce the Russian presence there. In the summer of 1900, Sissoi Veliky supported the international campaign against the Boxer Rebellion in China.
