context_page_description: 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.
context_section_description: Both of the Type 052 destroyers were upgraded in 2011. The four Type 76A guns were replaced by two Type 730 CIWS on top of the helicopter hangar. The Crotale/HHQ-7 short-range SAM may have been replaced by the newer model (FM-90?) which provides better interception against sea-skimming AShMs. Two Type 726-4 decoy launchers were installed on the sides of the forward bridge for better self-protection. Various onboard systems were integrated together (to a certain degree) by a Thomson-CSF TAVITAC combat data system which is thought to have been replaced by a new indigenous C3I system (ZJK-4B or a newer model). The Thomson-CSF Sea Tiger air/surface search radar was first replaced by an indigenous Type 518 Hai Ying radar and is now replaced by a Type 517M long-range air search radar. The Type 362 air/surface radar installed on top of the aft mast has been replaced by a Type 364. A pair of SATCOM antennas has been installed on top of the helicopter hangar as well.
