Business Insider:
The US Navy today faces a devastating missile gap between its two biggest rivals, Russia and China, but a new upgrade could quite literally blow the two competitors out of the water.
The US Navy’s destroyers and cruisers field advanced missile defenses and far-reaching land-attack cruise missiles, but the Harpoon, the current anti-ship missile first fielded in 1977, has been thoroughly out-ranged by more advanced Chinese and Russian systems.
China’s YJ-18 and YJ-12 each can fly over 240 miles just meters above the surface of the ocean. When the YJ-18 gets close to the target, it jolts into supersonic speed, at about Mach 3. When the YJ-12, also supersonic, approaches a target, it executes a corkscrew turn to evade close-in ship defenses.
