This Unruya class aircraft carrier, above, is pictured in Sasebo Bay in 1945. Note the submarine on her port side with yet more submarines in the middle ground. The Kong&#333; class of 4 battlecruiser / battleship (26,230 ton, length 728 ft), were the most active capital ships of the Japanese Navy during World War II. Only the Kong&#333; was built in England (Barrow-in-Furness, Aug 1913). She was active during World War I and afterwards as one of the fastest units, at 27 knots, of Japan’s battle fleet.
