The large-scale naval drills, known as Invincible Spirit, kicked off Monday and are due to run for six days, the South’s navy said in a statement.
On Monday, the allies carried out exercises involving ship-to-ground and submarine-to-ground cruise missiles with average flight ranges of up to 1,000 km, the South Korean Defense Ministry said.
The exercises come just days after reports that the North may be making preparations for a sixth nuclear test or a long-range rocket launch…….
The reclusive nation [North Korea] also stoked concern in August when it claimed to have successfully test-fired a submarine-launched ballistic missile (SLBM). North Korean leader Kim Jong Un called that test “the greatest success” after the missile landed in Japan’s air defense identification zone, flying about 500 km — its longest test-flight by a weapon of that type.
The SLBM test has left the United States, South Korea and Japan worried that further developmental successes could give the North a difficult-to-detect weapon that would pose a serious security threat to all of them.
The U.S. and its Asian allies have responded to the North’s tests by showing off their own military muscle.
Late last month, the U.S. and South Korea conducted joint naval exercises in the Sea of Japan after Washington earlier in the month flew two supersonic bombers over the South — with one landing on the Korean Peninsula for the first time in 20 years.
One of the bombers also flew the closest a B-1B strategic bomber had ever flown to the border between the North and South. It was the second time in less than a month that the U.S., which has about 28,500 troops in South Korea, had flown bombers over the country. http://www.japantimes.co.jp/news/2016/10/10/asia-pacific/u-s-south-korean-joint-naval-drills-kick-off-nuclear-powered-uss-ronald-reagan-set-take-part/#.V__uQeV97Gg
