The Type 052 Luhu-class is one of the first modern multi-role guided missile destroyers built by China. There are currently two units in active service with the People's Liberation Army Navy Surface Force. It was succeeded by the Type 051B.

Designed by the China Warship Design Institute (formerly the Seventh Academy of the Ministry of National Defense), both ships were built at Jiangnan Shipyard - No. 112 Harbin was the first Luhu destroyer followed by No. 113 Qingdao. The chief designer was academician Mr. Pan Jingfu (潘镜芙). The class is said to be the first indigenous Chinese warship design approaching modern standards, a significant improvement over the earlier Luda class. The Luhu class made extensive use of foreign technologies that were accessible to the PRC prior to the Tiananmen Square incident of 1989. These included French-made radars and fire-control systems and the General Electric LM2500 gas turbine engines from the US, two of which power each ship. The Type 052 became the first Chinese destroyer design to use gas turbine engines, and also the first equipped with a integrated combat system.

Even with incorporation of Western technology, the chronic lack of adequate shipborne air defense systems has had great impact on PLAN operations. Equipped with a small number of surface-to-air missiles with visual-range only and guns with limited range and performance, Chinese warships have historically limited their operations to the area covered by their land-based aircraft due to a lack of fleet defense capability. To rectify this trend, the Luhu destroyers (and the smaller Jiangwei class frigate) were fitted with the HQ-7 SAM that gives them much better air defense capability than other previous Chinese designs, although they are still limited to within visual range (WVR).
