North Korea’s military said on Monday that its recent missile tests were practice to “mercilessly” strike key South Korean and US targets such as air bases and operation command systems with a variety of weapons likely to have included nuclear-capable ones.
The North’s announcement underlined leader Kim Jong Un’s determination not to back down in the face of his rivals’ push to expand their military exercises. But some experts say he also used their drills as an excuse to modernise his nuclear arsenal and increase his leverage in future dealings with Washington and Seoul.
North Korea fired dozens of missiles and flew warplanes toward the sea last week – triggering evacuation alerts in some South Korean and Japanese areas – in protest at massive US-South Korean air force drills that the North views as an invasion rehearsal.
US and South Korean officials responded that they would further enhance their joint training events and warned the North that the use of nuclear weapons would result in the end of Mr Kim’s regime.
The General Staff of North Korea’s military said in a statement carried by state media: “The recent corresponding military operations by the Korean People’s Army are a clear answer of (North Korea) that the more persistently the enemies’ provocative military moves continue, the more thoroughly and mercilessly the KPA will counter them.”
It said the weapons tests involved ballistic missiles loaded with dispersion warheads and underground infiltration warheads meant to launch strikes on enemy air bases; ground-to-air missiles designed to “annihilate” enemy aircraft at different altitudes and distances; and strategic cruise missiles that fell in international waters about 50 miles (80km) off South Korea’s south-eastern costal city of Ulsan.
The North’s military said it also carried out an important test of a ballistic missile with a special functional warhead aimed at “paralysing the operation command system of the enemy”. This could mean a simulation of electromagnetic pulse attacks, but some observers doubt whether North Korea has mastered key technologies to obtain such an attack capability.
The North’s military statement did not explicitly mention a reported launch last Thursday of an intercontinental ballistic missile aimed at hitting the US mainland, though its main newspaper published a photo of an ICBM-like missile as one of the weapons mobilised during last week’s testing activities.
Some experts say many other North Korean missiles launched last week were short-range nuclear-capable weapons that place key military targets in South Korea, including US military bases there, within striking range.
Later on Monday, South Korea’s military disputed some of the North’s accounts of its missile tests.
Spokesman Kim Jun-rak said South Korea did not detect the North’s cruise missile launches and that it is also notable that North Korea did not mention what Seoul assessed as an abnormal flight by an ICBM.
This year’s “Vigilant Storm” air force drills between the United States and South Korea were the largest-ever for the annual autumn manoeuvres. They involved 240 warplanes including advanced F-35 fighter jets from both countries.
The allies were initially supposed to run the drills for five days, ending on Friday, but extended the training by another day in reaction to the North’s missile tests.
On Saturday, the final day of the air force exercises, the United States flew two B-1B supersonic bombers over South Korea in a display of strength against North Korea, the aircraft’s first such flyover since December 2017.
South Korea’s Joint Chiefs of Staff said the participation of the B-1Bs in the joint drills demonstrated the allies’ readiness to sternly respond to North Korean provocations and the US’s commitment to defend its ally with the full range of its military capabilities, including nuclear.
After their annual meeting in Washington on Thursday, US Defence Secretary Lloyd Austin and South Korean Defence Minister Lee Jong-Sup issued a joint statement strongly condemning the North’s recent launches and carrying Mr Austin’s warning that any nuclear attacks against the United States or its allies and partners “is unacceptable and will result in the end of the Kim regime”.
South Korea’s military has previously warned the North that using its nuclear weapons would put it on a “path of self-destruction”.
Both defence chiefs also agreed on the need to enhance combined exercises and training events to strengthen readiness against North Korean nuclear and missile threats.
Even before the “Vigilant Storm” drills, North Korea test-launched a slew of missiles in what it called simulated nuclear attacks on US and South Korean targets in protests of its rivals’ other sets of military exercises that involved an American aircraft for the first time in five years.
In September, North Korea also adopted a new law authorising the pre-emptive use of its nuclear weapons in a broad range of situations.
South Korean and US officials have steadfastly maintained that their drills are defensive in nature and that they have no intentions of invading the North.
The US and South Korean militaries have been expanding their regular drills since the May inauguration of conservative South Korean President Yoon Suk Yeol, who has promised to take a tougher stance on North Korean provocations.
Some of the allies’ drills had previously been downsized or cancelled to support now-stalled diplomacy on North Korea’s nuclear programme or to cope with the Covid-19 pandemic.
For months, South Korean and US officials have said North Korea has completed preparations to carry out its first nuclear test in five years.
On Monday, South Korean Unification Minister Kwon Youngse told politicians that North Korea could carry out the nuclear test at any time but there are still no signs that such a test explosion is imminent.
