What is the primary purpose of the DF-21D missile?

The primary purpose of the DF-21D missile is to serve as a "carrier killer," specifically designed to target and destroy aircraft carriers at sea. This missile features advanced technologies, including a range of maneuverability and terminal guidance, which enhance its effectiveness against moving maritime targets. The DF-21D is part of China's efforts to develop asymmetrical warfare capabilities, allowing it to counterbalance the naval superiority of other nations, particularly in the Asia-Pacific region.

The design and strategic intent behind the DF-21D underscore its role in anti-access/area denial (A2/AD) strategies, where adversaries aim to deter or defeat larger naval forces, such as those carried by aircraft carriers, within contested maritime environments. This capability has significant implications for naval warfare, as it poses a credible threat to surface vessels, altering operational planning and maritime security strategies for nations relying on carrier strike groups.
