Recently, two variants of the vertical launch system (VLS)—standard and extended—aboard China’s Type 052D destroyers appeared together in the same frame for the first time, drawing significant attention. The Type 052D is a domestically developed mainstay air-defense destroyer of the Chinese Navy, equipped with a universal VLS capable of launching multiple missile types. The standard VLS cells are approximately 7 meters deep, primarily used for medium-to-long-range surface-to-air missiles like the HHQ-9B, while the extended cells reach nearly 9 meters in depth, designed specifically to accommodate larger missiles such as the YJ-21 hypersonic anti-ship ballistic missile. The coexistence of both VLS types signals an ongoing functional expansion and mission diversification of the 052D class—some vessels are being partially retrofitted to enhance anti-ship or ballistic missile defense capabilities. This not only underscores the Chinese Navy’s emphasis on multi-role combat platforms but also reflects a broader trend toward modular and standardized weapon systems. In the future, such ‘mixed-configuration’ setups may become standard for upgraded 052D variants and subsequent warships, significantly boosting fleet operational flexibility and strategic deterrence.
近期，中国海军052D型驱逐舰的两种垂发系统——标准型与加长型——首次同框亮相，引发广泛关注。052D型驱逐舰是中国自主研制的主力防空驱逐舰，配备通用垂直发射系统（VLS），可兼容多种导弹。其中，标准垂发单元深度约7米，主要用于发射中远程防空导弹如HHQ-9B；而加长型垂发单元深度接近9米，专为搭载更大型号导弹（如鹰击-21高超音速反舰弹道导弹）设计。两款垂发同框，表明052D正经历功能拓展与任务多样化升级：部分舰艇通过局部改装，增强对海打击或反导能力。这不仅体现中国海军对多任务作战平台的重视，也反映出其装备体系正向模块化、通用化方向演进。未来，这种“混装”配置或将成为052D改进型乃至后续舰艇的标准模式，进一步提升舰队整体作战灵活性与战略威慑力。
