The country fired a medium-range ballistic missile, with South Korea, the United States and Japan conducting a joint aerial exercise involving nuclear-capable B-52H bombers just hours later.
Pyongyang’s latest launch comes less than two weeks after its leader Kim Jong-un supervised a solid-fuel engine test for a new intermediate-range hypersonic missile (IRBM), with experts suggesting yesterday’s launch could be of the same weapon.
Seoul’s military said the missile, launched early yesterday, flew around 600km before splashing down in waters between South Korea and Japan.
The Joint Chiefs of Staff said the military was analysing the launch, with a defence official telling the Yonhap news agency that it had likely involved a hypersonic warhead “on top of the delivery system used in the engine test last month”.
North Korea has long sought to master more advanced hypersonic and solid fuel technologies, to make its missiles more able to neutralise South Korean-US missile defence systems and threaten America’s regional military bases.
In January, Pyongyang said it had launched a solid-fuel IRBM tipped with a hypersonic warhead, then last month flagged the successful engine test of the “new-type intermediate-range hypersonic missile”.
Hypersonic missiles are faster and can manoeuvre mid-flight, making them harder to track and intercept, while solid-fuel missiles do not need to be fuelled before launch, making them harder to find and destroy, as well as quicker to use.
Seoul’s defence ministry said it conducted a joint aerial exercise with Washington and Tokyo yesterday involving a nuclear-capable B-52H bomber and F-15K fighter jets near the Korean peninsula.
The drill aimed to “improve joint readiness against the North’s nuclear and missile threats,” it added.
The launch yesterday “appears to be part of Pyongyang’s missile development blueprint, including hypersonic weapons,” said Han Kwon-hee of the Korea Association of Defence Industry Studies.
It seems Kim is developing such technology domestically, rather than with Russian help “given the sensitive nature of the weapons”, he added. — AFP
