The "Yangyan" class destroyer is a type of fleet destroyer designed and produced by Japan after getting rid of the constraints of the Washington Treaty and the Treaty of London after japan got rid of the constraints of the Washington Treaty and the Treaty of London after the end of the First World War, which is the prelude to the golden age of the development of the Japanese Navy.
The basic parameters of the Yangyan-class destroyer are 118.2 meters long, 10.8 meters wide, the normal displacement is 2540 tons, the maximum speed is 35-36 knots, the endurance is 5000 at 18 knots, some of the subsequent ships have reached nearly 6000 nautical miles, the crew is 239 people, the power system is three fuel boilers, two steam turbines, the main engine output power is 52000 horsepower, the design maximum speed is 35 knots, the endurance is 5000 nautical miles /18 knots, and the maximum range is 6000 nautical miles.
The main combat weapons were 3 double-mounted guns of the 50-caliber 127 mm C type, 2 single-barrel 25 mm anti-aircraft guns were initially installed, and the subsequent 25 mm anti-aircraft guns were increased to 28, and 4 12.7 mm anti-aircraft machine guns were added, and 2 type 4 610 mm heavy torpedo tubes were installed, equipped with Type 93 oxygen torpedoes, with mine laying and minesweepers, torpedo reloading devices, and the mine-laying and minesweepers in the stern were removed and replaced with 4 depth bomb throwers.
The avionics system and the hydroacoustic system are mainly: Type 3 sonar and Type 94 2 meter rangefinder for the main gun, And Type 91 Type 3 azimuth tester and Type 92 shooting commander for torpedoes. In 1943, the installation of the No. 1 Type 3 air-to-air radar (more than 1,000 units in total) and the Type 1-1 sea-to-sea radar were successively installed.
The main weapon 50 times caliber 127mm C type double-mounted gun (the first few types of ships are A, B type), gun length 6.48 meters, gun weight 4.2 tons, turret weight 31 tons, projectile weight 23.5 kg, usually only equipped with grenades and can take into account the air and ground shooting of the three types of ammunition, the subsequent firepower of the ship to improve the installation of armor-breaking shells, the gun muzzle initial speed of 915 m / s, the maximum range of 18380 meters, the maximum rate of fire to the sea 11 rounds / min, air: 4 rounds / min. With the requirements of air defense missions in the later stages of the war, most of the Yangyan-class destroyers replaced one with a main turret and replaced it with a 25mm anti-aircraft gun.
The ship of this class is also equipped with two type 24 610mm heavy torpedo tubes, mainly launching the Japanese Navy's heirloom Type 93 oxygen torpedo, the full mine is 9 meters long, 610 mm in diameter, weighs 2600 kg, using pure oxygen as the main propellant, the warhead is loaded with high explosives 490 kg (later 780 kg), a single shot can make a destroyer completely incapacitated, the maximum range of 48 knots / 20000 meters.
The power system is three fuel boilers, two steam turbines, at the beginning of the military command is required in the warship engine to power up to 6000 horsepower, so it is necessary to install a boiler or upgrade the boiler technology, the installation of boilers needs to redesign the hull, Japan's weak overall industrial strength is too difficult, so the Yangyan class uses a new type of heavy oil water tube boiler, reducing the consumption of fuel and increasing the range to meet the design requirements.
The battle of the Yangyan-class destroyers is completely based on the Japanese Navy's "nine-stage gradually reducing attack tactics", when the MAIN fleet of the United States army marches to Japan, the Japanese Navy will be in its voyage, and the Yangyan-class destroyers will cooperate with other navies to attack by various means, by sinking or severely damaging their warships, so that the main force of the US Navy fleet will be reduced to a lower than the Japanese Navy, or equivalent to the Japanese Navy.
However, this tactic has long been unsuitable in the war period of rapid development of science and technology, and the form of the battlefield has long been not a single fleet decisive battle that can be won or lost, perhaps Japan can win in several battles, but in the face of the enemy's all-round and system-wide attack and suppression, Japan with its teeth and claws is only destined to be crushed slag.
One of the most legendary destroyers of this type was the last very fortunate "Undead Bird Snow Wind", which remained until the end of the war, handed over to China as a trophy to change its name to "Danyang", and then served until retirement and dismantling.
