Two more nice views of KAWACHI....... :)

She and her sister had the odd main weapons fit of 4-12" 50s, the other 8 were 12"/45s. Fire control must have been interesting. DFO

Lead Ship, Dreadnought Battleship Kawachi pictured fitting out at Yokosuka Naval Arsenal on October 20th 1911...Her and Settsu were a two-ship class built for the IJN in the first decade of the 20th century. Both ships bombarded German fortifications at Tsingtao during the Battle of Tsingtao in 1914, but saw no other combat in World War I. Kawachi sank in 1918 after an explosion in her ammunition magazine with the loss of over 600 officers and crewmen. Settsu was disarmed in 1922 and converted into a Target Ship two years later to meet the terms of the Washington Naval Treaty and served until she was sunk in 1945 by American Carrier aircraft. She was refloated after the war and scrapped in 1946–1947.

Lead Ship, Dreadnought Battleship Satsuma pictured at Sasebo Naval Arsenal in 1916...She was laid down at Yokosuka Naval Arsenal on May 15th 1905. She was launched on November 15th 1906 with Emperor Meiji, the Navy Minister, and other high officials on hand for the ceremony, and completed on March 25th 1910. At the time of her launching, Satsuma had the largest displacement (19,700 tons) of any Battleship in the world. On August 5th 1911, she suffered an explosion in one of her 12-inch guns when it failed to fire during gunnery practice. After some time passed, the breech was opened and ignited the propellant; the resulting explosion and fire killed 16 crewmen and several officers. Satsuma was assigned to the 1st Battleship Squadron when World War I began in August 1914. She served as Rear Admiral Tatsuo Matsumura's flagship in the Second South Seas Squadron as it seized the German possessions of the Caroline and the Palau Islands in October 1914. Satsuma rejoined the 1st Battleship Squadron in 1915, was refitted at Sasebo Naval Arsenal in 1916 and served with the 1st Squadron for the rest of the war. Sometime during the war, she was fitted with two 12-pounders on high-angle mounts to serve as AA guns. She was disarmed at Yokosuka Naval Arsenal in 1922 to comply with the provisions of the Washington Naval Treaty, stricken from the Navy List on September 20th 1923 and converted into a Target Ship. Satsuma was sunk by Battleships Mutsu and Nagato off the southern tip of the Bōsō Peninsula, near the mouth of Tokyo Bay on September 7th 1924.
