How can "veteran" class frigates be competent for new combat missions?

How can "veteran" class frigates be competent for new combat missions? Frigate is a "veteran" in naval equipment, and its definition and function are different in different periods. Nowadays, people call the small tonnage warships that mainly perform anti-submarine and air defense tasks frigates, and their activities are generally in the central and offshore areas.

During the sail warship period, frigates were smaller in tonnage and faster than battleships. They generally perform tasks such as battlefield reconnaissance, alert surveillance, fleet escort, and destruction of maritime traffic lines, but generally do not participate in the decisive battle of the fleet.

Since the end of19th century, with the development of power system and weapon system, the types of warships have also changed. At that time, navies of various countries divided warships into battleships, cruisers, destroyers and frigates according to their functions. Development was once neglected.

During World War II, the frigate Dust was put into use again. In order to quickly make up for the lack of destroyers and strengthen the anti-submarine capability, the British Navy developed a river-class warship named frigate. This level of weapons and equipment is very simple, but the cost is low and the practicality is strong. It can carry out ocean escort missions.

As a result, frigates were "resurrected" again after 60 years, and navies of various countries followed suit.

At this time, the US Navy developed fleet destroyers and escort destroyers. Fleet destroyers are mainly used for decisive battles at sea with a speed of 25-30 knots.

Escort destroyers, also known as escort destroyers, mainly undertake tasks such as fleet escort, self-defense air defense and anti-submarine. They are small in tonnage, slow in speed and relatively low in cost. At that time, there was a small-tonnage patrol frigate, mainly used for maritime patrol, with a tonnage of about 1500 tons and a speed of about 20 knots. The representative is the Tacoma class patrol frigate of the United States, with a total of 96 ships built.

Before and after World War II, the British and American navies also developed a class of ships called "guided missile destroyers", which mainly enhanced the formation command and control function and anti-submarine and air defense capabilities. It also belongs to a branch of frigate, but in practical application, it is not often used as a command ship, but more as a guard for mobile formations.

After the war, the task of escort destroyers was replaced by a class of ships called ocean frigates, and its main task was anti-submarine. In the 1970s, the US Navy collectively referred to escort destroyers, ocean-going frigates and patrol frigates as frigates.

From 65438 to 0975, the US Navy began to build Perry-class frigates under the guidance of the equipment development idea of "high and low collocation".

Since then, the United States once gave up the development of frigates. 2/kloc-at the beginning of the 20th century, in the process of military transformation, a "littoral combat ship" was developed, which was mainly responsible for anti-submarine and mine warfare. After several years of use, it was found that the ship was not practical, so it was incorporated into the frigate sequence.

In 20 17, the US Navy decided to "bring order out of chaos" and return to tradition, and began to design and build a new FFG-X frigate, named Constellation.

The names of frigates are not as complicated as before, and they are generally only called frigates and light frigates. However, judging from the task, the boundary between frigates and destroyers is becoming more and more blurred, because with the enhancement of functions and the expansion of tasks, the displacement of frigates is gradually increasing, and its tonnage has already exceeded that of cruisers before the war. ?

In order to hide people's eyes and ears, Japan called the destroyer "frigate", which means to protect the ships belonging to the fleet, not the ship type. The 26,000-ton Izumo-class helicopter carrier is also known as the helicopter frigate in Japan.
