Frigate destroyer (destroyer frigate difference)
Let's start with the definition. For destroyers, the definition is a multi-purpose warship, which is a medium-sized warship with strong assault force in the naval fleet. At the same time, it can also undertake air defense, anti-submarine, landing support and anti-landing operations, as well as patrol alert, maritime blockade and rescue tasks. It can be said that the destroyer's functions basically cover all the functions that the fleet needs in naval battles except that it can't take off and land fixed-wing aircraft and can't dive into the water to fly to the sky.
Let's talk about frigates. The definition of frigate is very similar to that of destroyer. They can perform anti-submarine and patrol missions, but the difference with destroyers is that frigates are light warships, and their tonnage and firepower are often inferior to destroyers in modern naval formations. In other words, the functional coverage of frigates is narrower than that of destroyers. As the name implies, frigates tend to "guard" and protect their fleets and interests in the central and offshore areas.
Traditional destroyers are designed around torpedo attack warfare, which determines that destroyers need higher speed and lighter tonnage to ensure maneuverability. They played an auxiliary attack role in the battle, and were responsible for carrying out reconnaissance missions and reconnaissance of the enemy before the war. The traditional frigate is for anti-submarine escort, which has low requirements for tonnage and relatively more important functionality.
But these were decades ago. With the continuous development of technology, the concepts of universality, modularity and serialization of modern shipbuilding industry are also constantly improving. The situation of early driving and protecting aliens no longer exists today, but driving and protecting the same type is becoming the mainstream trend of future warship development.
Simply put, destroyers and frigates are nominally two kinds of warships, but there are actually many overlaps: needless to say, there may be overlaps in construction, that is, the same berth, the same equipment and the same group of people are built. This is the result of the three modernizations of shipbuilding mentioned this morning. In this context, the difference between destroyers and frigates may be only the difference in functional coverage and tonnage, and the rest are basically the same.
In terms of functional coverage, destroyers can generally perform more tasks, while frigates tend to guard. The difference in tonnage is also an important reason for the different functional coverage to some extent. Because of the higher tonnage, destroyers can often carry more functional modules, such as a dozen or dozens of frigates on vertical holes, which gives them the possibility of carrying more different types of missiles. However, frigates cannot develop more comprehensive capabilities like destroyers because of their insufficient tonnage, so they tend to specialize in one or several functions to ensure the necessity.
Therefore, destroyers are generally equivalent to sea generalists, while frigates are sea bodyguards. This reflects the changes in modern naval warfare: the Pacific War has determined the unshakable position of the aircraft carrier in the navy, and the air superiority has since become the focus of contention between the warring parties. Many old warships in the past can no longer meet the needs of modern warfare, but after these old warships withdraw, new warships not only need to adapt to modern naval battles with air superiority, but also make up for the gap caused by the departure of these old warships. Therefore, the development of new warships to generalists and panaceas can be said to be an inevitable result.
The difference between destroyers and frigates will be smaller and smaller in the foreseeable future-however, this situation may be more aimed at naval powers such as China, the United States and Russia, as well as warships of ordinary countries, and they are not even qualified to participate in the discussion of "destroyers or frigates".
The difference between destroyers and frigates
The difference between destroyers and frigates
1. Different definitions, destroyers refer to medium-sized warships with various combat capabilities such as missiles, torpedoes and naval guns. Frigate refers to a light surface combat ship with anti-submarine torpedo guns and missiles as its main weapons.
2. With different functions, destroyers are mainly used to attack submarines and surface ships, fleet air defense, escort, reconnaissance patrol alert, mine laying and attack onshore targets. Frigates are mainly used for escort of ship formations, as well as reconnaissance, vigilance, patrol, mine laying and landing support.
3. Different tonnage, the tonnage of destroyers is about 6,000 to 7,000 tons; The tonnage of frigates is around 4000 tons.
What is the level of 055 in the world?
The Type 055 destroyer is the most powerful destroyer of the People's Liberation Army, and there are currently six destroyers in service. The destroyer Type 055 may be the main warship of China Navy in the future, among which 107 and 108 ships have conducted several rounds of sea trials, and China 1 batch of destroyers Type 055 have appeared in front of people. According to the latest news, the second batch of Type 055 destroyers of China Navy is also under construction and will be in service in 2025. The technical level of Type 055 large destroyer is in a leading position in the world, and it is also the most advanced combat ship.
The technology of Type 055 destroyer has surpassed that of the western navy, and it occupies a very important position in the history of China's naval development. Even the US Navy is not as good as the Type 055 destroyer in technical performance. Although the United States also has battleships that compete with the Type 055 destroyer, American battleships will not be in service until 2030, which means that the Type 055 destroyer will crush destroyers around the world in the 2020s. With the continuous development of technology, 055 destroyer has also made great breakthroughs in information technology.
Type 055 destroyer will bring great visual impact to people, but compared with its size, it is advanced information equipment that can better reflect combat vessels's attack power. Type 055 destroyer has made great achievements in multi-band radar, which not only has very strong detection ability, but also reflects the development level of China on warships. Dual-band radar has very strong detection and information acquisition ability, and it can also obtain the desired information by cooperating with radars of different bands.
The technology of dual-band radar is difficult to realize, so multi-band radar is very challenging for many countries. The navies of many countries are stuck in dual-band radar, let alone multi-band radar. Type 055 destroyer may become an important force in the future maritime combat system, with many advantages such as small position, relatively low cost, strong general ability, and being able to use different types of missiles. Compared with some foreign destroyers, the cost of Type 055 destroyer is relatively cheap.
What are destroyers and frigates?
First, the playing time is different
1. The destroyer appeared in the 1990s.
2. The appearance time of frigates:16th century.
Second, the executive function is different.
1. destroyer: the main duties of modern destroyers are escort, as well as reconnaissance, patrol, mine laying and attacking onshore targets. Its extensive combat functions make destroyers the most widely used ships in modern naval vessels.
2. frigate: it can carry out escort, anti-submarine, air defense, reconnaissance, alert patrol, mine laying, landing support, protecting the flank of the offshore army and other combat tasks. It was once called escort ship or escort destroyer. In modern naval formations, frigates are surface warships with tonnage and firepower second only to destroyers. However, due to their small tonnage, their self-sustaining power is weaker than that of destroyers, and their ocean-going combat capability is inferior to that of destroyers.
Third, the tonnage is different.
1, destroyer: 1000 tons or more.
2. frigate: more than 500 tons.

How many destroyers are there?
China 13 052D destroyer Lhasa has been launched and is expected to enter service next year!
Type 052D destroyer is the latest destroyer in service of China Navy in recent years. Compared with before, it has been greatly improved in air defense, radar and vitality. At present, the destroyer 052D is also one of the main warships of our navy, and it bears a heavy burden. Last year, China's latest Lhasa ship was launched, and it is expected to enter service next year. Let's take a look at it today.
052D destroyer is a type of guided missile destroyer equipped by the Chinese people's liberation army navy. At present, seven destroyers have been in service, six have been installed and many more are under construction. It is the latest improvement of Type 052C destroyer, and another modern air defense destroyer equipped with phased array radar and vertical launch area air defense missile system after Type 052C destroyer.
The first 052D destroyer Kunming was launched on August 28th, 20 12, and officially joined the PLA Navy battle sequence on March 28th, 20 14.
At present, there are 13 Type 052D destroyers launched and put into service in China, the latest of which is Lhasa, which was launched on June 26th last year and is expected to be put into service next year.
Lhasa has a length of 157 m, a width of 19 m, a draft of 6 m, a full-load displacement of 7,000 tons, a capacity of 280 passengers and a speed of 32 knots.
The Lhasa ship will soon be equipped with the South China Sea Fleet, which will greatly enhance the strength of the South China Sea Fleet.
The layout and ship form of Lhasa ship are the same as those of the previous 052D ship, and the inward contraction angle of both sides of the ship body is larger, so the front of the bridge becomes narrower and the inclined planes for installing phased arrays on both sides become larger. 052D is replaced by a new phased array, which tends to be square in shape, and has a larger area without the arc cover of 346 phased array.
There are four sets of eight-pack vertical launch systems in front of the bridge of Lhasa ship, while the hangar structure is equipped with four other sets of eight-pack vertical launch systems, so there are 64 units in total. Compared with the thermal vertical launching system previously used for Haihongqi-16 shipborne air defense missile, the new vertical launching tube of 052D is square and similar in overall size, but the exhaust flue is cancelled to make room for the missile launching tube, thus increasing the aspect ratio of each missile launching slot.
As for the short-range defense weapon system, the 30mm short-range weapon system of 1 130 was still maintained in front of the bridge in 052D, but a new HQ- 10 short-range air defense missile launcher imported from China in 20 10 was refitted above the hangar, adopting a 24-pack configuration. Originally, 052C was used to install the anti-ship missile launcher, and 052D was used to install four sets of eight-pack vertical launch systems.
Lhasa can be equipped with a Ka -28 or Zhi -9 anti-submarine helicopter at the stern. The outline and configuration of the rear hull of 052D are basically the same as that of 052C, but the poop structure has obviously changed. First of all, the hangar has been moved from the left side to the middle position, and closed cabins similar to 054A have been added on both sides. The rear mast used to carry the Yagi antenna of the 5 17HA radar also moved forward. Because a vertical launching system is set between the rear mast and the hangar, the 5 17HA radar moved forward, away from the missile flame.
The launching of Lhasa means that 14 destroyer 052D will not appear too far away. It is estimated that it will be launched this summer. I hope our navy will become stronger and stronger!
