A brief introduction to the ships of the Fletcher class destroyers

<> "Fletcher-class destroyers.

In World War II, the United States, as the main force against the Japanese in the Pacific Theater, relied on their outstanding performance and strong combat capabilities.

This Fletcher-class destroyer is a destroyer designed by the United States in 1940 to imitate the source cover. The length of the destroyer's hull is meters, the width of the hull is meters, the draft is meters, and the power system is capable of providing 60,000 horsepower, so it can reach a maximum speed of thirty-seven knots, a standard displacement of two thousand one hundred tons, and a full load displacement of three thousand and fifty tons.

The Fletcher-class destroyer was designed for superior maneuverability, high speed, and long-lasting endurance, so the destroyer's power system consisted of two high-performance steam turbines and four oil-fired boilers, with twin-shaft and twin-propeller propulsion, but the main engine output was increased to achieve higher speeds.

Secondly, this Fletcher-class destroyer is also the first class destroyer of the US Navy to install radar when it was built, and each of its ships is equipped with a complete radar system when it is in service. Including the air search radar and the sea search radar, these two pieces of equipment make this destroyer occupy a greater advantage in the competition with the Japanese Navy.

Another point is that this Fletcher-class destroyer has a very advanced ** system, and the most important weapon of this destroyer is its main gun ** system, which is composed of five 127 mm high-level dual-purpose naval guns and its firing control device, which is mainly responsible for the dual mission of striking surface ships and long-distance air targets.

In terms of the choice of medium and short-range air defense**, this Fletcher-class destroyer did not do well at first, but later, the US Navy chose a twin 40mm machine gun. The launch stability of this cannon is first-class, the firepower is continuous and lasting, and the ballistic performance is excellent, which is obviously better than the similar equipment of the British and American navies, so it was quickly determined to be a new generation of medium and short-range air defense ** for this destroyer, which perfectly fills the biggest shortcoming of this destroyer.

After this Fletcher-class destroyer was designed and developed, it soon became the main warship of the U.S. Navy destroyer fleet at that time, and in just two years, 175 ships were built, and participated in various important naval battles in the latter part of World War II, and played an outstanding role in the war.

Overall, in the era of "speed needed" at that time, the birth of this Fletcher-class destroyer allowed the US Navy to occupy a greater initiative at sea and made great contributions to the final victory of World War II for the United States.

<> destroyers of the Friesian class.

The "Friesland" class destroyers are an improved version of the "Dutch" class destroyers, and eight "Friesland" class destroyers were completed in 1956.

The "Friesland" class destroyer is 116 meters long, wide and has a draft of meters. The displacement amounted to 3119 tons.

**Armament is two twin-barreled 120mm high-level dual-purpose guns with a rate of fire of 50 rounds per minute, equipped with a sophisticated reloading and control system. Equip one at the bow and one at the stern of the ship. "The "Friesland" class ships were the first destroyers without torpedoes.

The ship was protected by armor on both sides and deck, which was relatively rare in destroyers. The middle part of the hull is equipped with 6 famous Bofors 40mm anti-aircraft guns. Two Bofors 375mm anti-submarine rockets and two deep-bomb launchers in front of the bridge serve as anti-submarine **.

These ships represent the last form of artillery-armed destroyers, on which missiles ** have already begun to be installed at that time. Two ships of this class were equipped with British Mk20E anti-submarine fish launchers, but they were dismantled in 1961.

The Friesland class is equipped with a new power strap system with a matching design. Four BW boilers are responsible for the high-pressure steam generation, which in turn passes through two steam turbines to output up to 60,000 hp to the two propulsion shafts. It has a maximum speed of 36 knots and a cruising range of 4,000 nautical miles and 18 knots.

During its service, most of the ships were deployed in the Dutch sphere of influence in Southeast Asia after the war, and became the last symbol of Dutch colonization. In 1972, all 8 "Friesland" class destroyers were decommissioned, and all but the first ship were given to the Peruvian Navy.

<> "Introduction to the destroyer.

The destroyer is a medium-sized destroyer with missiles, underwater guns, and naval guns as the main ones, and has a variety of combat performance. It is one of the ships with strong assault power in the formation of the ** navy. It is used to attack submarines and surface ships, fleet air defense, escort, reconnaissance, patrol, vigilance, mine-laying, attack on shore targets, etc.

The world's first destroyer was built by the British in 1893. Subsequently, both the United States and China successively built destroyers with a large tonnage at that time. Before World War I, Britain, Germany, Russia, France, the United States and other countries built nearly 600 destroyers.

Missile destroyers appeared in the 50s of the 20th century.

In the 60s, the United States, the Soviet Union, Britain, France, Canada, Japan and other countries installed anti-submarine *** on destroyers. The **, command and control systems, power plants of destroyers in many countries have been improved accordingly. Its development trend is to enhance the early warning, offensive and defensive, maneuverable, and seaworthiness capabilities, and adopt advanced devices and new technologies to improve the ability to resist the poor envy of guidance.
