SS Kamchatka was a Russian steamship,(built as a collier) which entered service as a repair ship in the Russian Baltic Fleet in 1903. Her main features were a large hold and large cranes that made her ideal for the role as a repair ship. The ship was infamous for its actions during the voyage of the Second Pacific Squadron, where it precipitated the Dogger Bank incident, as well as numerous other incidents including misidentification of neutral vessels as torpedo boats, and mistakenly firing at the Russian cruiser "Aurora". The ship was lost with all hands when it was sunk in 1905 during the Battle of Tsushima to Japanese shell fire.
