North Korea boasts of its new long-range missile targeting the US

SEOUL, South Korea (AP) — North Korea on Friday bragged of its recently tested new intercontinental ballistic missile, calling it “the world’s strongest,” a claim viewed by outside experts as propaganda though the test showed an advancement in the North’s quest to build a more reliable weapons arsenal.

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 had so far fired. It signaled that the North has achieved progress in acquiring a nuclear-armed ICBM that can hit the U.S. mainland. But foreign experts assess that the country has still a few remaining technological issues to master before acquiring such a functioning ICBM.

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

KCNA said leader Kim Jong Un observed the launch, describing it as “an appropriate military action” to express North Korea’s resolve to respond to its enemies’ moves that escalated tensions and threats to North Korea’s national security. It said 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 didn’t say what propellant the Hwasong-19 ICBM uses. Observers say the color of exhaust flames seen in North Korean media photos on the launch still suggest the new ICBM 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
