North Korea boasts of ‘the world’s strongest’ ballistic missile after test

North Korea has dubbed its recently tested new intercontinental ballistic missile “the world’s strongest,” a claim viewed by outside experts as propaganda.

A missile launched by North Korea on Thursday flew higher and stayed in the air for a longer duration than any other weapon the country has fired.

It signalled that the North has achieved progress in acquiring a nuclear-armed ICBM that can hit the US mainland, but foreign experts assess that the country has a few remaining technological issues to master before acquiring such a functioning weapon.

On Friday, the North’s Korean Central News Agency (KCNA) identified the missile as Hwasong-19 ICBM and called it “the world’s strongest strategic missile” and “the perfected weapon system”.

It said Mr Kim thanked weapons scientists for demonstrating North Korea’s “matchless strategic nuclear attack capability.”

South Korea’s military earlier said that North Korea could have tested a solid-fueled missile, but Friday’s KCNA dispatch did not say what propellant the Hwasong-19 ICBM uses.

Observers say the colour of exhaust flames seen in North Korean media photos on the launch suggest the missile uses solid fuels.

Before Thursday’s test, North Korea’s most advanced ICBM was known as the Hwasong-18 missile which uses solid fuels.

Pre-loaded solid propellants make it easier to move missiles and require much less launch preparation times than liquid propellants that must be fueled before liftoffs, making it more difficult for opponents to detect launches by solid-fuel missiles.

There are questions on whether North Korea has acquired the technology to shield warheads from the high-temperature, high-stress environment of atmospheric re-entry.

Many foreign analysts say North Korea requires improved altitude control and guidance systems for missiles. They say North Korea needs an ability to place multiple warheads on a single missile to defeat its rivals’ missile defenses.

All of North Korea’s known ICBM tests, including Thursday’s, have been performed on steep angles to avoid neighbouring countries.

South Korean military spokesman Lee Sung Joon said on Thursday that a high-angle trajectory launch cannot verify a missile’s re-entry vehicle technology, although North Korea has previously claimed to have acquired that technology.

Observers say Thursday’s launch, the North’s first ICBM test in almost a year, was largely meant to grab American attention days before the US presidential election and respond to international condemnation over North Korea’s reported dispatch of troops to Russia to support its war against Ukraine.

North Korea’s reported troop dispatch highlights the expanding military cooperation between North Korea and Russia.

South Korea. the US and others worry North Korea might seek high-tech, sensitive Russian technology to perfect its nuclear and missile programs in return for joining the Russian-Ukraine war.
