Similar in capability to the Russian S-300 and American Patriot systems, the HQ-9 uses a HT-233 PESA radar system.[7] The naval variant, HHQ-9 (simplified Chinese: 海红旗-9; traditional Chinese: 海紅旗-9; pinyin: Hǎi Hóng Qí-9; literally: 'Sea Red Banner-9'), appears to be identical to the land-based variant. HHQ-9 is equipped in the PLAN Type 052C Lanzhou class destroyer in VLS launch tubes.[8]
