Fears and questions about North Korea’s growing nuclear arsenal

North Korea’s latest missile launches are a demonstration of the country’s avowed ability to use nuclear force against South Korea and the mainland U.S. How immediate is that threat?

North Korea claims its nuclear forces are capable of destroying its rivals, and often follows its provocative weapons tests with launch details. But many foreign experts call the North’s claims propaganda and suggest that the country is not yet capable of hitting the United States or its allies with a nuclear weapon.

There’s no question that North Korea has nuclear bombs, and that it has missiles that place the U.S. mainland, South Korea and Japan within striking distance. What’s not yet clear is whether the country has mastered the tricky engineering required to join the bombs and the missiles.

North Korea has demonstrated that it has missiles that could fly far enough to reach deep into the continental U.S., but it’s not clear whether they can survive re-entering the Earth’s atmosphere on arrival.

North Korea said it launched a Hwasong-15 intercontinental ballistic missile on Saturday to verify the weapon’s reliability and the combat readiness of the country’s nuclear forces. It’s one of three kinds of ICBMs the country has developed, along with the Hwasong-14 and Hwasong-17. All three are liquid-fueled, and North Korea has portrayed them all as nuclear-capable.

Launched almost straight up to avoid the territories of neighbors, the weapon reached a maximum altitude of about 3,585 miles and flew 615 miles, according to North Korean state media. The reported flight details suggest the missile could travel 8,080 miles or beyond if launched on a normal trajectory.

“These days, North Korea has been disclosing information about its launches in a very detailed manner to try to let others believe what they’ve done is genuine,” analyst Shin Jong-woo at South Korea’s Defense and Security Forum said. “But I think that’s part of their propaganda.”
