Type 051 Luda - Variants
After the 051-type destroyer was put into service, the Chinese Navy discovered problems, new technology development, and changes in operational requirements. During the subsequent construction and service of the 051-type destroyer, it continued to make improvements and modifications and technical upgrades to the ship. 051 destroyer in 20 years of development, production process, the formation of a destroyer family includes 051 basic, 051D type, 051Z, 051G and other models a total of 17 ships, and become the backbone of China's surface ships that age.
Type 051
This type of warship includes: Jinan (105), Xi'an (106), Yinchuan (107), Nanjing (131), Guangzhou (160), Changsha (161), Nanning (162). The basic type of the 051 destroyer was the first batch of ships built. Due to the large demand for the 051 type by the Navy, the time was more urgent. After the first ship was started, it was built in 1970. Dalian and Guangzhou shipyards each built 3 One ship, built by Shanghai Zhonghua Shipyard, was built and served in succession during the 1970s. Limited to the industrial level in China at that time, the design of the first batch of 051 ships in the first batch of ships has improved the design and construction process. Some radars and electronic equipment have not kept up with the progress of shipbuilding and have not been installed. Some equipment has not been finalized and shipped to the ship, which has poor reliability and affects the use of combat readiness. Type 051 was officially approved by design in 1975. In September 1975, the 131 ship built by Shanghai Zhonghua Shipyard had created a speed record of 37.95 knots during the high-speed sea trial.
Type 051D
This type of warship includes: Xining (108), Kaifeng (109), Chongqing (133), Zunyi (134), Nanchang (163), Guilin (164). The 051D destroyer is the second batch of ships that are officially finalized and started to build in batches (D stands for finalization). After 1976, since 108 ships, 051D ships have built a total of 6 ships, 4 were built by Dalian Shipyard and 2 were built by Guangzhou Shipyard. The focus of this type of ship is to correct the problems exposed in the construction and use of the improved basic type. The main change is to replace the double 57 mm naval gun with a double 37 mm naval gun. The firing rate of the original double 57mm gun was not high and was eventually abandoned. The 051-type ship that was built before was returned to the factory for maintenance, the double 57-mm gun was removed and the double 37-mm gun was modified. In addition to naval guns, there are more than 40 changes to the 051D, including radar systems, anti-submarine electronic command systems, radio communication systems, satellite navigation systems and maritime supplies system etc. Later, the "Haiying-1A" anti-ship missile was used. The flying height was reduced to 50 meters. The frequency agile technology was used to guide the radar. The range was increased to 95 kilometers (51 nautical miles). Air conditioning facilities were added to the 164 ship built at the latest for the 051D to improve the living conditions of the crew.
051Z type
This type of warship includes: Hefei (132), Dalian (110). In 1977, in order to cooperate with the intercontinental missile flight test and ocean-going survey mission code-named " 718 Project " to be carried out in 1980, in order to implement unified command of the surveying fleet and escort formation, the Navy decided to develop the 051Z command ship (Z representative command) The command ship is mainly to enhance the communication function. The formation command room has been added, with multi-channel, ultra-short wave communication capabilities. It also solves the problem of oil and water supply equipment modification. The first 132 ship of the 051Z type was constructed at the Shanghai Zhonghua Shipyard in December 1977.
This ship served as a command ship. After it was delivered to the East China Sea Fleet in 1980, it participated in the escort mission for the intercontinental missile launch test and measurement fleet and served as a formation Command ship. The second 110 ship was launched in September 1981. The ship hull was shelved at the dock for two years because the main engine and other equipment could not be delivered on schedule. The ship was delivered to the North Sea Fleet in December 1984. In the modification of the 051Z ship in the mid-1980s, 381 three-coordinate air-to-air radar and 637-II intelligence center were added. The 132 ship was equipped with the "Poseidon 1" combat command system from March to August 1988-this constituted the first generation combat command system of the Chinese destroyer and was the first Chinese naval warship equipped with this system.
051DT
051DT type ship: Kaifeng (109) was selected as a platform for testing new equipment in the mid-1980s. In 1987, China signed an agreement with the French Thomson Company to purchase two sets of French Thomson Sea Rattlesnake ship-to-air missile systems. From October 1989 to December 1990, during the conversion of the 109 ship at the Dalian Shipyard, a set of "Sea Rattlesnake" anti-aircraft missile system was installed at the original dual 37mm naval gun at the stern for the test (the other set was installed at Type 052 destroyer 112). As ancillary facilities, the 109 ship also modified the Thomson-CSF TAVITAC combat data system introduced by France, the "Sea Tiger" radar, and the communication system imported from the United Kingdom. At the end of the 1990s, the 109 ship was refitted again, replacing the old-fashioned "Sea Eagle" anti-ship missile with four quadruple-mounted "Eagle Strike-83" (YJ-83) anti-ship missiles. The 76A double 37mm fully enclosed automatic The gun replaced the original dual 37mm anti-aircraft guns and modified modern fire control systems and electronic equipment, including 360 search radars, 342 and 344 fire control radars. China has carried out mid-term upgrades to several 051-type destroyers with better ship conditions, all of which are upgraded and transformed at once according to the 109 ship standard. In 2002, the 110 ship received a similar one-time modification.
Type 051S
In the early 1980s, China had intended to buy British Type 42 destroyers, and carry out imitation and give up because of budget issues. After consultations between the two countries, the modification of the 051S project was listed as the focus of military and technical cooperation between the two sides. The Chinese navy initially envisaged only a full modernization of the six 051-type destroyers in service, mainly covering shipborne weapons, fire control radar, command, electronic countermeasure equipment and combat command centers, with the emphasis on improving the air defense operations of fleets and single ships. ability.
However, after entering the negotiations, the British side found that the design concept of the 051 ship was still at the level of World War II based on the design data of the 051 destroyer provided by China. On the existing basis, the ship must be rebuilt and designed to include a large amount Special cabins for modern combat command centers are set up, so that the Chinese and British sides will redesign the 051 destroyer as necessary.
Reached a consensus, this is the origin of 051S. The specific assumption of the ship is that it adopts a high freeboard deck ship type with a normal displacement of 4100 tons. It is equipped with British "sea javelin" regional air defense missiles, so that the 051S ship has certain sea formation regional air defense and strong single-ship air defense operations. ability. In this plan, China is considering modifying two 051-type ships and building six new ships of the same type. And on the successor ship, the localized "Sea Javelin" missiles, gas turbines, "Dolphin" helicopters, A324 torpedoes, and "Eagle Strike" -8 missiles were successively installed. However, during the 1982 Massachusetts War , two Type 42 ships sank and one was seriously injured. The sound of dissatisfaction with Type 42 destroyers appeared within China. The cost required exceeded the budget. stranded. In general, if the 051S can serve in time, it can solve the situation of the Chinese navy lacking regional air defense capabilities. The situation until after the planned introduction of 20 years, the PLA Navy imported from Russia Modern-class destroyers, began to be eased.
Type 051G1: Zhanjiang (165); Type 051G2: Zhuhai (166)
After the 051S plan failed, the 051G design was determined in November 1983. Ships 165 and 166 were constructed at the Dalian Shipyard in August 1986 and October 1987, respectively. Focus on improving the automation of combat command systems and the electromagnetic compatibility of radar and radio equipment, improving short-range air defense capabilities, and improving anti-ship capabilities. The overall combat effectiveness has been greatly improved compared with the 051D, and accumulated experience for the development and construction of next-generation destroyers.
The biggest difference between the 051G1 / G2 and the old ship is the use of a fully enclosed bridge and hull; the original "Sea Eagle-1" missile (051G2 type) was replaced with the "Sea Eagle-1A" anti-ship missile. The 166 ship was replaced with the "Eagle Strike-8" or YJ-8 anti-ship missile), replacing the original dual 37mm anti-aircraft gun with a 76A dual 37mm fully enclosed automatic anti-aircraft gun, and a triple anti-submarine torpedo launch tube (American MK46) anti-submarine torpedo), also experimentally equipped with a towed variable depth sonar imported from Italy (due to excessive noise and vibration generated by the hull's own power system, which is not ideal for use and later removed during conversion); 381 A three-coordinate space The radar, the 347 type fire control radar system, the imitation RM-1290 navigation radar replaced the 751 radar, the 352 C radar with agile frequency conversion system replaced the 352 A radar, and the 825 type electronic countermeasure system was installed, and the introduction was installed. Combat data system. Electronic equipment as a whole reached the level of Western countries in the late 1970s. NATO listed the ship as a Luda III ship.
In the later modernization, the 165 ship / 166 ship was modified according to the 109 ship modification standard. The eight-unit "Haiqi-7" missile (HHQ-7) anti-aircraft missile (the legal "Sea Rattlesnake" anti-aircraft missile localized model) system, four quadruple-mounted "Eagle-83" anti-ship missile systems, correspondingly modified radar and electronic warfare and other electronic equipment, the difference is that it is replaced the original dual-mounted 100mm caliber guns by two double 130mm caliber naval gun.
