The presence of three aircraft carrier strike groups in the area was also mentioned in President Donald Trump's speech in South Korea, the second leg of his five-nation tour of Asia that drew both supporters and anti-war protesters.
The last time such drills were held was during the Valiant Shield exercises in 2006 and 2007, which took place off the coast of the USA territory of Guam, which hosts two US military bases and is on the North Korean radar for a potential missile strike.
YOKOSUKA - The USS Ronald Reagan (CVN 76), USS Nimitz (CVN 68), and USS Theodore Roosevelt (CVN 71) strike groups will commence a three-carrier strike force exercise in the Western Pacific, Nov 11-14. A decade ago, Valiant Shield (VS) 2006 and 2007 had operated together off the coast of Guam, a USA island territory in Micronesia, and focused on the ability to bring together forces from all the three strike groups in response to any regional situation.
The three carriers will be likely together in the drills around Monday.
During the drill, the first of its kind in a decade, the warships will carry out air strike and defense simulations, maritime surveillance, sea supply, coordinated fenced maneuvers and other training, added the Navy.
The United States and South Korea on Saturday, Nov. 11, 2017, started joint naval exercises that will involve three US aircraft carriers in what military officials describe as a clear warning to North Korea. Ronald Reagan participated in VS 2006 while Nimitz took part in VS 2007.
The exercise will involve three of the Navy's 11 carriers, and concentrate more aircraft carriers the combined fleets of China and Russian Federation. The Fleet is just as committed to maintaining those security commitments for the next 70 years.
Pyongyang detonated its sixth and most powerful nuclear bomb in September after months of ballistic missile tests that riled Washington and its allies Japan and South Korea.
Also on Saturday, the US and South Korean navies launched four days of joint drills off the east coast of South Korea.
During his recent visit to Seoul, Trump said, " North Korea is not the paradise your grandfather envisioned.
