Will North Korea’s New Missile Push US to Expand Missile Defenses

North Korea showed off a new intercontinental ballistic missile (ICBM) at a big military parade earlier this month.

Security experts say the missile appears designed to overpower U.S. missile defenses. They believe it may push the United States to add costly2 new anti-missile defenses to guard against the new weapon.

The huge ICBM is the largest ever shown by North Korea. Commentators3 say it is likely to be the "new strategic weapon" promised by North Korean leader Kim Jong Un at the beginning of the year. A strategic weapon is one that can strike from a great distance.

The missile was presented at a parade marking the 75th anniversary of North Korea's ruling Workers' Party.

Little is known about the weapon, which is being called the Hwasong-16. But experts say North Korea is likely trying to show it can put several nuclear warheads on a single missile. That would make intercepting5 such a weapon more difficult and costly for U.S. missile defense1 systems.

Costly defense system

"If you have multiple warheads coming out of that single missile, you now have to have multiple interceptors for each incoming warhead," said Melissa Hanham. She studies North Korea's weapons program and is deputy director of the Austria-based Open Nuclear Network.

The new ICBM, Hanham said, appears large enough to be deployed6 with many warheads. It is so large that it may also be able to hold decoys, which are meant to confuse anti-missile systems.

Hanham noted7 that such missiles are not only costly, but they increase the cost of defense systems designed to stop them. She added that it is less costly and easier to build a new missile than to create a missile defense system.

Andkit Panda is a nuclear policy specialist at the U.S.-based Carnegie Endowment for International Peace. He says the United States will have to spend hundreds of millions of dollars to keep up with changes in North Korea's growing force.

The United Nations expanded sanctions against North Korea in 2017 after the country carried out a series of nuclear and ICBM tests. The U.S. and North Korea were involved in nuclear negotiations8 in 2018 and 2019. But North Korea eventually walked away, angry at the U.S. refusal to ease the sanctions and provide security guarantees.

U.S. officials have dismissed concerns that North Korea's missile program could produce a weapon able of avoid ground-based U.S. missile defenses.

In January, General John Hyten, vice9 chairman of the Joint10 Chiefs of Staff, said he had "100% confidence" in their ability.

However, independent defense experts wonder about U.S. missile defenses, especially if North Korea deploys11 ICBMs with multiple warheads.

Markus Garlauskas and Bruce Perry are two former members of the U.S. intelligence community. They wrote that: "It is hard to see how Americans could be confident that...U.S. missile-defense interceptors would be sufficient to stop an attack...by North Korean ICBMs with multiple warheads each."

The two noted that building more interceptors might be too costly.

Is a test in the future likely?

North Korea's new ICBM, however, does have strategic issues. The missile is carried by a transporter launch vehicle that has at least 22 wheels. The launcher may be too large to travel on many North Korean roads, which are often in poor condition.

The large size of the missile also means it likely must travel with a team of fuel trucks and machinery12 to help lift it, Hanham said. She added that preparing the missile for launch would take hours. That would permit observers to identify the missiles setup. In addition to that, the missile remains13 untested.

But some experts say that could change. In January, the North Korean leader said that he no longer felt he had to continue his own ban on nuclear and long-distance missile tests.

U.S. President Donald Trump14, however, has warned Kim against any provocations15 before the U.S. elections on November 3. Kim may be unwilling16 to risk such a test.

Bruce Klingner is a North Korea specialist at the Washington, D.C.-based Heritage Foundation.

Klinger told VOA, "What I would expect is to see that ICBM tested next year." He added: "North Korea tends to...do something very provocative17 in the first year of a new U.S. or South Korean administration."

Hanham said that North Korea may watch to see what happens in the U.S. elections. Although the North may choose to do nothing, they "have a powerful way of signaling their dissatisfaction now by testing this missile," she said.
