Russian cruiser Asia

Asia (Russian: А́зия) was a cruiser of the Imperial Russian Navy. The ship was originally the Philadelphia-built iron merchant steamship Columbus completed in 1874 
The iron passenger-cargo steamship Columbus was built 1873/74 in Philadelphia by William Cramp & Sons as Yard No.184 for local shipowner William P Clyde & Co.
"Columbus" was bought by Russia in May 1878, one of three merchant ships purchased in the United States to be transformed into naval cruisers: "State of California" became "Europa", "Saratoga" became "Afrika", and "Columbus" became "Asia". After initial conversion by her builders, Cramp, in Philadelphia, she was sailed to Russia by a Russian crew for further outfitting in Kronstadt during 1878 and 1879.
The cruiser saw initial duty in the Far East, but then returned to the Baltic. She was downgraded to Cruiser 2nd Class on 1 February 1892. The future Vice Admiral Karl Jessen was her commanding officer in 1895 and 1896. In 1898 she received a new engine, increasing her power from to , and adding to her top speed.
In August 1911, now rather obsolete, "Asia" was transferred to the reserve fleet. In October 1912 she was renamed "Kaukas" (Russian: "Кавказ"). Following the outbreak of the First World War, she was once again renamed "Asia" on 11 September 1914, assigned to the Baltic Fleet's transport squadron and used as a minelayer.
The ship was deactivated in May 1918 and scrapped in 1923.
