    After the Russian-Japanese War, it was decided to build battleships and cruisers of the program in 1906 (1903 according to the plans of the financial year) on state-owned shipyards, under which were laid vYokosuka and Kure class ships "Sadzuma." < / p>

    Frames on both the Japanese ships have put much more closely than in large U.S. courts or England, namely with an em space only about 800 mm. Two bilge keel to limit roll occupied about one-third the length of the two battleships. The wood was limited to only the most necessary.

    Dimensions superstructures decreased as much as possible. Their conning habitually distinguished by their small size, while in the other fleets, especially in the German and American constructors already inclined to increase their size. Both were equipped with anti-torpedo nets armadillo. Ships like "Sadzuma" forecastle had no guns and the main fire on the same level.

    armor protection, is already considered insufficient, consisting of a complete belt of Krupp armor, who had in the middle of the thickness of 229 mm, thinned to bow up to 152 mm (according to other sources, 127 mm) and to feed up to 102 mm. Above the main belt was second, thick in the middle of 203 mm and thinned to nose up to 127 mm. It extends from bow to stern barbette. From the second zone between bow and stern bridges to the upper deck was the third - 152 mm thick. Karapasnaya deck armor had a thickness of 51 mm in the horizontal portion and 76 mm on the bevel. While more feared grazing fire than attachment - before the tragedy Hood was still far off.

    significant slowdown of construction "Sadzuma" occurred, according to the explanation of Japanese newspapers 1910., due to changes that followed after the descent of the water of ships, of their artillery weapons. It was originally supposed to install them, following the example of the British ships tipaNelson, gun caliber 305 and 254 mm, and only then decided to install the arms, which became such a classic Dreadnought - only from one 305-mm guns.

    In Japan, of course, know the opinion of the British Admiralty that fire management is greatly simplified for the adoption of all the major instruments of a single size (and this could confirm the validity of their own combat experience) and that the average 152-mm artillery became less important and 75-mm guns are sufficient to repel the attacks of destroyers. Aviation is not yet afraid.

    The feasibility

    rejection of 152-mm guns hotly debated during construction. In the end it turned out that Japanese shipbuilders triumphed cautious compromise version of different calibers with 305-and 254-mm guns for both ships and 120-mm artillery for mine "Sadzuma", and 152 mm for "Aki". Scheme with a single main battery after a long discussion then recognized impractical. Of course, of great importance and had insufficient funding after the war fleet.

    Increasing the number of trunks

    single main 305-mm caliber allowed, on the one hand, to increase the range of possible destruction of the enemy, and on the other, made when the system had more rapid-firing guns useless smaller caliber, the weight of each shell in the total volley was very high. At large distances no longer get to use the method used so successfully iron rain and had it cast and again get behind the calculations.

    But the old version was much cheaper and - draft modernized type "Kashima" armadillo cost less dreadnoughts, and scientific research and then verify in practice do not have to spend money. As a result, Japanese designers dream about a ship with a large artillery odnokalibernoy incurred before the construction of "Sadzuma" were temporarily shelved until better times and for reasons conjugate as to the drafting of such a ship, so its construction and financing.

    Thus, ships like "Sadzuma", though sometimes called dreadnoughts, in fact, due to heterogeneity of heavy artillery rightly attribute it to dodrednoutnoy era (battleships) ..


    August 1914 "Sadzuma" met as part of the 1st Squadron, then in 1915. became the flagship of the 2nd (South) Squadron and in the same year he was transferred in the 1st Squadron of the 1st Fleet. In 1916, the ship stood at Sasebo for repairs, after which from 1917 to 1918. again was part of the 1st Squadron, and in December 1921 was 4 Division 3 squadron of battleships.

    In 1922, the battleship, lasted only 12 years, pursuant to the conditions of the Treaty of the five Powers, disarmed in Yokosuka, transferred to Kure. September 20, 1923 he was stricken from the Naval and ship converted into a goal. September 7, 1924 skeleton "Sadzuma" sunk in Tokyo Bay battleship Nagato and Mitsu.


    Combat Life "Aki" was short and inconspicuous. The outbreak of World War II, he met in Kure, in 1915-17. was a member of the 1st Squadron of the First Fleet in 1918 was transferred to the 2nd squadron. In 1919 he was repairing.

    September 20, 1923 turned out to be struck from the Navy list (according to other sources, in 1922) by the Treaty of five powers, converted into a ship-goal and 2 September 1924 in Tokyo Bay sunk by artillery and battleships Congo , Haruna.
