Russia's announcement last Saturday that it will sell Syria the supersonic Yakhont anti-ship cruise missile was a testament to Iran's rising regional power and the US's loss of power.
Complementing the anti-ship ballistic missiles, China has purchased advanced Russian anti-ship missiles like the supersonic Sunburn and the very advanced Club-two-stage anti-ship missile. (We need to ensure that our ship defense can defeat these missiles).
China is likely developing a new strategic bomber, and has recently revealed that it has a supersonic, air-launched, anti-ship missile called the YJ-12, that can be launched by its bombers and fighter-bombers.
