Type 052B destroyer

The Type 052B or Guangzhou class destroyer (NATO reporting name: Luyang I class) is a class of multirole missile destroyers built by the People's Republic of China. Two ships have been built, with Guangzhou (168) and Wuhan (169) both being commissioned into the People's Liberation Army Navy Surface Force in July 2004. This class features a stealthy hull and significantly improved air defence systems, an area that had been a major weakness on previous ships designed by China. These ships represent a major improvement over older generation vessels and reflects the PLAN's need for more modern destroyer designs.

Programme

The Type 052B (Guangzhou class) multirole missile destroyer was the first Chinese-built warship capable of area air defence. When domestic systems could not be ready in time for Type 051B destroyer, China was forced to purchase two pairs of Sovremennyy-class destroyer to fill the gap left behind in the fleet area air defense. By the time of Type 052B, China had already gained tremendous experience from Russian systems and Chinese domestic systems were also ready. As a result, Type 052B is built with considerable Russian technology including the Russian-made 9M38 Buk-M1-2 (NATO codename: SA-N-12 Grizzly) air defence missile system, an extremely effective air defence system with a range of 38 km. Most military analysts expect the Guangzhou class to be similar to the Russian Sovremenny class destroyer in terms of general performance.

Type (designation)

The word Type followed by a number is a common way to name a weapon or product in a production series, similar in meaning to "Mark". "Type" was used extensively by the Japanese and Chinese militaries beginning in the 1920s, and is still in current use by the militaries of both nations. The United Kingdom uses a type number system for much of their military equipment. Many other nations use the word "Type" to designate products in a series.

Japan

The Imperial Japanese Navy (IJN) began using the Type-Number System in 1921 to designate aircraft accepted for production. The numbers used after the word "Type" were based on the number of years that the Emperor Taishō had reigned. Since his reign began in 1912, an aircraft ordered into production in 1921 would have been called "Type 10", the tenth year of the emperor's reign. At the end of 1926, the emperor died, leaving his son Hirohito as the Emperor Shōwa, and the numbering system was reset to mark the new emperor's reign.

In 1929, the government of Japan adopted a new system based on the imperial year. Aircraft ordered for production from 1929 onward were assigned the last two digits of the year marking the continuity of Japanese emperors. 1929 was the 2589th imperial year, so aircraft ordered that year were designated "Type 89". 1940 was the 2600th year, and the IJN numbering system was reset to single digits. New aircraft were designated 0 (zero). The well-known Mitsubishi A6M Zero was ordered into production in 1940 as the IJN "Type 0 Carrier Fighter" (Rei shiki Kanjō sentōki, 零式艦上戦闘機), and was popularly called the "Zero" because of its type.
