BB Settsu


Settsu seen here in her final appearance before being disarmed for use as a target ship, and then later, a radio-controlled ship (1938). Note that she is still carrying her torpedo net defence at this late date (August 1921).


The 21,440-ton Settsu and Kawachi, laid down in 1909 and completed in 1912, were Japan’s first dreadnoughts. Their twelve 12-inch guns were imported Armstrongs, but their Brown–Curtis turbine engines were made in Japan, under license by Kawasaki. Their armor, too, was manufactured in Japan, which had first produced Krupp armor under license for the two 13,750-ton armored cruisers of the Tsukuba class, laid down in Kure early in 1905 as replacements for the battleships Hatsuse and Yashima, lost to Russian mines earlier in the war. These warships, and the two 14,640-ton armored cruisers of the subsequent Ibuki class, eventually were re-rated as battle cruisers, owing to their large size and heavy primary armament of four 12-inch guns. 18 After laying down the Settsu and Kawachi, Japan waited three years to begin another dreadnought.
