Supersonic Strike: Japan Has Some Big Plans to Sink China's Navy In a War

Japan is developing a longer-range, air-launched anti-ship cruise missile. The reason? China’s navy is deploying longer-range anti-aircraft missiles, which means Japanese aircraft will have to launch their anti-ship weapons from longer range or risk being shot down.

Defense Minister Takeshi Iwaya cited longer-range air defenses on warships belonging to “some countries,” though there could be little doubt that he was referring to one nation in particular.  

“The plan involves extending the range of Japan's supersonic ASM-3 air-to-ship missiles, which are said to have a range of less than 200 kilometers [124 miles], to over 400 km [249 miles], with the aim of beefing up Tokyo's ability to defend a chain of outlying islands in the southwest,” according to Japan’s Mainichi newspaper.

“The F-2s are expected to retire in the 2030s and Iwaya said Japan is considering loading their successor fighter jets with the longer-range missiles,” Mainichi noted. Japan is developing the F-3, an indigenous stealth fighter.

What’s interesting is that the new missile is being developed even though Japan only finished developing its predecessor, the ASM-3, last year (for a graphic of the ASM-3, go here). The ASM-3 was designed to be launched by the F-2, Japan’s version of the U.S. F-16. The missile can either travel straight at the target ship from low altitude, or be launched low and “pop up” to high altitude before diving down on its target.
