Hatsuharu-class Destroyer
The were a class of Imperial Japanese Navy destroyers in the service before and during World War II. The final two vessels in the class, completed after modifications to the design, are sometimes considered a separate "''Ariake'' class". Background The provisions of 1930 London Naval Treaty stipulated that the overall destroyer tonnage for the Imperial Japanese Navy would be capped at 105,500 tons with a maximum permissible tonnage per ship of 1,850 tons. Furthermore, only 16 percent of the overall tonnage could be of this size, with the remainder not exceeding 1,500 tons per vessel. This effectively meant that additional units of the previous and destroyers could no longer be built. The Imperial Japanese Navy responded by ordering naval architects to design ships that were lighter by at least 260 tons, and yet mount the same armament.Stille, pp. 35–38 In the end, the new class ended up with one less gun (three turrets with five 127 mm guns instead of six), with a smaller ...

Sasebo Naval Arsenal
was one of four principal naval shipyards owned and operated by the Imperial Japanese Navy.

After the establishment of the navy base, a ship repair facility was established in 1889 with a dry dock. With the addition of equipment and facilities for ship production by 1897, the "Sasebo Shipyards" were officially established, and renamed the "Sasebo Naval Arsenal" in 1903. Construction of the arsenal was supervised by the French engineer Louis-Émile Bertin. In 1913, a 250-ton crane was installed, and the shipbuilding facilities expanded to permit the construction of large warships. With the mothballing of the Maizuru Naval Arsenal due to restrictions by the Washington Naval Treaty, much of the design and prototype work for new classes of destroyers and torpedo boats formerly done at Maizuru was shifted to ...
