Frigates and destroyers are both classified as military ships, and they have some significant differences in design and function.
First of all, from the point of view of design and function, a frigate is a kind of ** smaller than a destroyer, which is mainly responsible for performing patrol, alert and anti-submarine tasks. Its main task is to protect the transport fleet, conduct reconnaissance and strikes against enemy submarines, as well as perform other auxiliary tasks. In contrast, a destroyer is a large ** that is mainly responsible for performing combat missions, including strikes, reconnaissance and patrolling enemy ships, etc. Destroyers are more advanced in armament and usually have more missile launchers and artillery.
Secondly, in terms of displacement and tonnage, frigates generally have less displacement and tonnage than destroyers. The destroyer has a larger displacement and tonnage, which can carry more first-class equipment and personnel, and also has better stability and seakeeping.
In addition, the construction and cost of corvettes is relatively low, since their design and functionality are relatively simple. In contrast, destroyers are more expensive to build and cost, as their design and functions are more complex and require more technology and resources for manufacturing and R&D.
What are the new frigates and destroyers in our country?
1.056 frigate (NATO codename: Jiangdao-class).
At present, China's main frigates have more than 70 Type A frigates (NATO code: Jiangdao class), and Type 056 frigates are a type of low-cost surface ships tailored by the Chinese Navy for long-term daily coastal patrol tasks in the past few years, mainly used to replace the retired Type 037 hunting submarines and Type 22 missile boats, as well as the early Type 053 frigates and other old ships. The captain 889 meters, width 1114 meters, draft 43 meters, standard displacement 1300 tons, full load displacement 1440 tons, crew establishment 60 people. With an overall stealth design, the superstructure is low, and the overall layout is compact and concise. The power plant is a diesel engine with a rated total power of 12200kw, a maximum speed of 25-30 knots, and a cruising range of 2000 nautical miles of 18 knots.
As a corvette mainly positioned for offshore patrols, the Type 056 frigate has a relatively simple ship electrical system and armament system. The ship's electrical system only has a simple machine-scan-to-air and sea-to-sea warning radar, as well as some basic navigation radars and communication systems. The armament system has only one H PJ-26 76 mm rapid-fire naval gun (with fire control radar gate H PJ-17 single-barreled 30 mm naval gun, two twin YJ-83 anti-ship missile launchers, two triple 324 mm torpedo launchers, and one 8-pack HQ-10A short-range anti-aircraft missile launcher. Although the stern of the ship is equipped with a flight deck, which can be used for the take-off and landing of domestic Z-9C D carrier-based *** or UAVs, there is no hangar.
2.Type 055 destroyer (NATO code: Blade Sea class) Type 052D destroyer (NATO code: Luyang class).
At present, there are more than 30 large destroyers represented by D, and the displacement of Type 055 is about 110,000 tons of standard displacement, a larger displacement provides it with better hull stability and space for the installation of shipboard equipment. The Type 055 destroyer measures about 180 meters in length and 21 meters in width, making it a relatively large destroyer. The power system adopts a composite power system, including a gas turbine and an electric motor, which can be flexibly adjusted and used in different situations to achieve high-speed navigation and low-speed cruise. The Type 055 destroyer is equipped with phased array radar and vertical launch systems (VLS), among others, and can carry a range of long-range air defense missiles, such as Haihongqi-10 and Haihongqi-9B, as well as medium-range anti-aircraft missiles, such as HHQ-16, and anti-ship missile systems equipped with anti-ship missile systems, such as YJ-18 (YJ-18) and YJ-12 (YJ-12), as well as the latest YJ-21 hypersonic missile, capable of delivering precision strikes against any target at sea and on the coast. The Type 055 destroyer is also equipped with an anti-submarine torpedo launch system for countering submarines, and can carry multiple *** such as the Z-8 series anti-submarine and rescue *** and the Z-9 series anti-submarine *** to provide support for maritime operations and reconnaissance.
The Type 052D destroyer is an upgraded 7,500-ton capital destroyer with a full load displacement on the basis of the Type 052C destroyer. Since the first Type 052D entered service in 2014, 25 Type 052D destroyers have entered service with the PLA Navy. Equipped with four Type 364A phased array radars and 64 square vertical systems, these destroyers can launch Hongqi-9C anti-aircraft missiles (with a range of more than 300 km) and YJ-18 anti-ship missiles (with a maximum range of 600 km). Their integrated combat capabilities are very strong. 100 help plan
