Seoul: North Korean leader Kim Jong Un observed a test of a high-thrust, solid-fuel engine test and hailed it as a development to boost the country’s strategic military capability, state media reported Sunday.
The test likely indicates Kim is intent on enlarging and modernising an arsenal of missiles capable of reaching the United States mainland.
The report Sunday from Korean Central News Agency (KCNA) came days after Kim delivered a speech at North Korea’s Parliament pledging to irreversibly cement his country’s status as a nuclear power and accusing the US of global “state terrorism and aggression,” in an apparent reference to the war in the Middle East.
Kim watched the ground jet test of the newly upgraded engine, which uses a composite carbon fibre material, according to KCNA, which reported the engine’s maximum thrust at 2,500 kilotons, up from about 1,971 kilotons reported in a similar solid-fuel engine test in September.
A push to increase the engine power is likely associated with efforts to place multiple warheads on a single missile to increase chances of defeating US defences, observers say.
The KCNA did not report exactly when or where the test occurred.
The test was conducted as part of the country’s five-year military escalation program. The plan’s objectives include upgrading “strategic strike means,” the KCNA reported.
The reference is understood to mean nuclear-capable, intercontinental ballistic missiles targeting the continental US.
Kim said the latest engine test had “great significance in putting the country’s strategic military muscle on the highest level,” the KCNA reported.
In recent years, North Korea has test-fired a variety of ICBMs demonstrating the potential range to reach the US mainland, including missiles with solid propellants that make detection before liftoff more difficult.
The country’s older liquid-fuel missiles must be fuelled before liftoff and cannot last long.
Some foreign experts say North Korea still faces technological hurdles before it has a functioning ICBM, such as ensuring its warheads survive the harsh conditions of atmospheric reentry.
But others dispute that assessment, given the number of years the country has spent on its nuclear and missile programs.
North Korea has pushed hard to expand its nuclear arsenal since Kim’s high-stakes diplomacy with US.
President Donald Trump collapsed in 2019. In a ruling Workers’ Party congress in February, Kim left open the door for dialogue with Trump but urged Washington to drop demands for the North’s nuclear disarmament as a precondition for talks.
