OVERVIEW: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. 

DETAILS: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.
