The Type 051B, also called the Luhai class, is a single-ship Chinese People's Liberation Army Navy guided-missile destroyer class built around the destroyer Shenzhen (DDG 167). Open references describe it as an experimental, modular design from Dalian Shipbuilding Industry Company, intended to improve Chinese experience with stealthier construction, fleet command-and-control, and modern naval systems before later PLAN destroyer families matured.
The Type 051B / Luhai class is best understood as a bridge design: one ship, one hull experiment, and a set of lessons that helped shape later PLAN destroyers. Sources describe Shenzhen as a modular, stealth-conscious test bed with fleet command-and-control capability, later upgraded with modern missiles and sensors.
