It was usually considered to be based on the Soviet Kotlin class destroyer design though some other sources say the Neustrashimy class destroyer, with some features from the Kotlin class. Chinas Peoples Liberation Army Navy decommissioned its Luda-class guided-missile destroyer Nanchang on 8 September, the vessel, which served with the PLAN for almost 34 years, was believed to be the countrys last active Type 051 destroyer. The ship is set to be sent back to Nanchang, Jiangxi Province, where it is expected to become a tourist attraction at a local military-themed park, the website added. In the late 1960s, China began testing its long-range rockets for the Chinese space program, the Peoples Liberation Army Navy Surface Force operated only four ex-Soviet Gnevny class destroyers at the time, which were unsuitable for long-range ocean recovery missions. The 701 institute was instructed to develop Chinas first indigenous guided missile destroyer, the design was approved in 1967, and construction of the first Type 051 Luda class destroyer began in 1968. A total of 16 Type 051 destroyers were built between 1968 and 1991, major refit for ships of this class began in the 1990s, replacing the old HY-1/HY-2 with YJ-83 missile, and manual guns with automatic guns. For air-defense, an 8-cell HQ-7 Surface-to-air missile system is installed with the upgrade. The general designers of Luda class destroyer were Mr. Li Fuli, a total of 732 types of material, and 1240 kinds of equipment were tasked to over a dozen establishments under Ministry of Industry in 22 provinces and municipalities. A total of 16 ships were constructed, consisted of 7 ships of the Type 051,6 ships of Type 051D, later versions are the subsequent upgrade of earlier units. This is the configuration of the design, albeit with equipment inconsistencies among the units. Three shipyards built the original 16 vessels of this group, units 106-109/133/134/165/166 in Dalian, units 110/131-132 in Shanghai, and units 160-164 in Guangzhou. Of these, Jinan was converted into Luda II type, Kaifeng and Dalian were converted into Luda III type, while Guangzhou suffered an explosion in August,1978 and was eventually scrapped. The original Luda destroyer was equipped with 2 x triple HY-1 or HY-2 missile launchers,2 x 130 mm guns, plus an assortment of manual 25 mm,37 mm and this initial batch is the first Chinese surface warship to have a bow-mounted sonar. A more capable indigenous Chinese sonar was ordered to be developed, sJD-1 sonar was jointly developed by 706th Research Institute, 726th & 461th Factories, and it is the first bow-mounted sonar adopted by Chinese navy. SJD-1 is frequently confused with its successor SJD-2, more commonly referred as SJD-II, whose design started in the 1970s, anti-ship missiles s of Type 051 was HY-1. This launcher / container /reloading system is designated as Type 7222, electromagnetic compatibility proved to be a major difficulty which caused AShM to be potentially detonated and launched, and this problem was not solved until the early 1980s. As a result, when Luda I class ships were deployed in 1982 to escort the convoy of submarine-launched ballistic missile testing, Type 051D is the 2nd batch of Luda I class, with D stands for Dingxing, meaning finalized design. The primary difference between Type 051D and earlier Type 051 is in electronics, to save valuable space, depth charge racks on Type 051 were eliminated
