The United States held joint air exercises bilaterally with South Korea and Japan involving strategic bombers on Sunday, a day after North Korea fired a Hwasong-15 intercontinental ballistic missile (ICBM) in a "sudden launching drill".
South Korea's Joint Chiefs of Staff said the exercise, in which South Korea's F-35A, F-15K, and U.S. F-16 fighters escorted American B-1B bombers, demonstrated the allies' "overwhelming" defence capabilities and readiness posture.
"(The exercise) strengthened the combined operation capability and affirmed the United States' ironclad commitment to the defence of the Korean Peninsula and the implementation of extended deterrence," the South's military said in a statement.
Japan flew F-15s over the Sea of Japan with the U.S. Armed Forces' B-1 bombers and F-16s in tactical exercises, Japan's Defense Ministry said in a statement, calling the security environment "increasingly severe" after the latest North Korea missile landed within its Exclusive Economic Zone (EEZ).
"This bilateral exercise reaffirms the strong will between Japan and the United States to respond to any situation, the readiness of (Japan's Self Defense Forces) and U.S. Armed Forces, and further strengthens the deterrence and response capabilities of the Japan-U.S. Alliance," the ministry said.
The air drills come a day after North Korea launched a long-range ballistic missile into the sea off Japan's west coast, following a warning of a strong response to upcoming military drills by South Korea and the United States.
North Korea's state media KCNA said the country conducted a "sudden launching drill" on Saturday an "actual proof" of its efforts to turn the "capacity of fatal nuclear counterattack on the hostile forces into an irresistible one".
Leader Kim Jong Un's sister, Kim Yo Jong, issued yet another warning and accused the United States of trying to turn the U.N. Security Council into what she called a "tool for its heinous hostile policy" toward Pyongyang.
"I warn that we will watch every movement of the enemy and take corresponding and very powerful and overwhelming counteraction against its every move hostile to us," she said in a statement.
Saturday's missile launch, the North's first since Jan. 1, came after Pyongyang threatened on Friday an "unprecedentedly persistent, strong" response as South Korea and the United States geared up for their annual military exercises as part of efforts to fend off the growing nuclear and missile threat that the North poses.
North Korea's state news agency said its missile had flown for 1 hour, 6 minutes and 55 seconds, as high as 5,768 km (3,584 miles), before accurately hitting a pre-set area 989 km (614 miles) away in open waters. It first test-fired a Hwasong-15 in 2017.
'WITHOUT WARNING'
Last year nuclear-armed North Korea fired an unprecedented number of missiles, including ICBMs capable of striking anywhere in the United States, while resuming preparations for its first nuclear test since 2017.
South Korean Foreign Minister Park Jin said Saturday's launch "clearly" signals the North's intent to conduct further provocations.
"If North Korea conducts the seventh nuclear test, which could happen at any time, it will be a game changer in a sense that North Korea could develop and deploy tactical nuclear missiles," Park told the Munich Security Conference on Saturday.
KCNA said the North's latest launch, guided by the Missile General Bureau, was conducted on an "emergency firepower combat standby order" given at dawn, followed by a written order from Kim Jong Un at 8 a.m. (2300 GMT on Friday). South Korea's military said it detected the missile at 5:22 p.m. (0822 GMT).
"The important bit here is that the exercise was ordered day-of, without warning to the crew involved," said Ankit Panda, a missile expert at the Washington-based Carnegie Endowment for International Peace. "The amount of time between the order and the launch is likely going to be decreased with additional testing."
Analysts say North Korea is likely to conduct more weapons tests, including a possible new solid-fuel missile which could help the North deploy its missiles faster in the event of a war.
North Korea's ballistic missile and nuclear weapons programmes are banned under U.N. Security Council resolutions, but Pyongyang says its weapons development is necessary to counter "hostile policies" by Washington and its allies.
