China is pursuing the development of very long-range, land-mobile, maneuverable re-entry vehicle-equipped (MaRV'd) antiship ballistic missiles (ASBMs), apparently a variant of the DF-21 medium-range ballistic missile (MRBM). Imagine very long-range artillery with great accuracy, that was land-mobile, making counter-battery fire virtually impossible. Then imagine that someone had the idea to turn it seaward and make it capable of hitting a ship under way. This is what China's ASBM amounts to: extraordinarily long-range coastal artillery.
Public awareness of Chinese ASBMs is gaining steam, as evidenced in this issue of Proceedings. This unprecedented anti-access capability has numerous implications for the U.S. Navy.
