North Korean leader Kim Jong Un thanked workers during a visit to a factory that built the tires for a huge vehicle used to transport a new intercontinental ballistic missile that was test-launched this week, the country's media reported yesterday.
The five-day Vigilant Ace drill - involving some 230 aircraft including F-22 Raptor stealth jet fighters - begins Monday, five days after the North test-fired an intercontinental ballistic missile believed to be capable of hitting the USA mainland in a new challenge to President Donald Trump. On Wednesday, 29 November, the North fired the long-range missile which flew about 950kms and touched an altitude of 4,475kms during the almost hour-long flight before hitting the sea waters off the Japan coast.
National Security Adviser H.R. McMastersaid Saturday that the chances of war between North Korea and the United States are "increasing every day".
Named Vigilant Ace, the air manoeuvres will simulate strikes on "mock North Korean nuclear and missile targets and transporter erector launchers that move the North's missiles", the South Korean Air Force was quoted by Yonhap news agency as saying on Sunday.

"Our initial analysis of the photos showed that there were clear differences between the Hwasong-15 and Hwasong-14 in terms of the looks of the warhead, the joint of the first and second stages of the missile, and overall size", Roh told a briefing on Thursday.
The North says the Hwasong-15 missile can be tipped with a "super-large heavy warhead" capable of striking the whole USA mainland. "We're asking China to act in China's interest, as they should, and we believe increasingly that it's in China's urgent interest to do more".
"We are in a race to be able to solve this problem", McMaster said.
