Kongo battlecruiser (1912) High resolution picture

The Kongo was a Japanese battlecruiser launched in 1912; she was the leading ship of her class and unlike the others she was built in British shipyards. The ships of the Kongo class were based on the British battlecruisers of the Lion class, but they were fitted with many improvements to satisfy the Japanese requirements. Instead of the 343-millimeter cannon in use in Britain the Japanese demanded that of caliber 356 millimeters to keep pace with the American progress. The third main turret was reallocated from within the funnels to after the superstructure, but still so its new position between the boilers and the engine room was far from ideal.

As the largest part of the projects of battlecruisers the Kongo class had a relatively weak protection theoretically vulnerable to heavy grenades at every range. The intention was to transport a heavy armament at high speed to pose a formidable threat to lighter units. The limitations imposed by the naval treaties of the interwar period caused the cancellation of the Japanese naval programs whose purpose was the creation of a modern fleet of capital ships. For such reason, the Imperial Japanese Navy preserved its veteran battleships modernizing them as much as possible. Along this period the ships of the Kongo class suffered a long series of small improvements, being reconstructed two times. The illustration shows the Kongo as she was in 1944; note the tall "pagoda style" conning tower crowned by a radar, the additional antiaircraft cannons and the seaplane E13A1 "Jake" on the catapult.

Initially conceived as battlecruisers, the ships of the Kongo class were reclassified as battleships in 1929 when their armor was slightly strengthened, and finally as fast battleships in 1937, after further improvement of their speed, to make them capable of accompanying the carrier fleet. After a hard service in the Pacific, the Kongo was eventually torpedoed and sunk by the submarine USS Sealion in November 1944. Two years ago, her sister Kirishima had been sunk in a matter of minutes by the modern battleship USS Washington, demonstrating this fact the obsolescency of the Kongo class.
