Current hypersonic missiles require extensive guidance to intercept their targets (i.e. hit them); momentum will carry a defeated hypersonic missile right into the water. The Dongfeng 21 is a ballistic missile, and not usually referred to as hypersonic; the latter usually refers to cruise missiles capable of travel at > Mach 3. In addition, the DF-21 is very unlikely to be used in a conventional war, as it may look like a tactical nuclear weapon. The DF-21 is also relatively easy to intercept, and could only be successful if used in a saturation attack; the Wikipedia article is written more like an advertisement than a fact-based informational piece.
