China Begins Testing of Russia’s S-400 Air Defense System Reportedly Capable of Downing F-35s

I wonder how long before the Chinese reverse engineer the S-400?  Even more worrisome is if this system or a Chinese knockoff ends up in North Korea in the future:

Russia’s TASS news agency and a Hong Kong daily report that China could test fire a new Russian missile defense system in the coming days.

The South China Morning Post said Saturday that China could put the defense system, which is capable of downing U.S. F-35 stealth fighters, through its paces within a few days.

The report says the Chinese army has already been trained in the use of the S-400 Triumph in Russia.

The S-400 Triumph, which was delivered just last week, is a surface-to-air missile system designed to complement China’s home-grown defense capabilities.

With a range of 24-hundred kilometers, the S-400 can engage up to 36 targets simultaneously with as many as 72 missiles at altitudes of between five meters and 30 kilometers.

The South China Morning Post said the U.S. has had F-35s at its own and allies’ military bases in the Asia-Pacific region since October and this deployment pushed China into bringing its first stealth fighter, the J-20, into service ahead of schedule in February.

Some pundits say the S-400 deployed on the Shandong Peninsula, which is near Korea, will pose a major threat to the combat power of South Korea and U.S. Forces Korea.   [KBS World Radio]
