US Taking North Korean Threats Seriously

ICBM

As part of the preparation for North Korea’s growing threat, the Pentagon will try to shoot down an intercontinental-range ballistic missile (ICBM) for the first time in a test. The goal is to more closely simulate a North Korean ICBM aimed at the U.S. homeland, officials recently told japantimes.co.jp.

The American interceptor has a spotty track record, succeeding in nine of 17 attempts against missiles of less-than-intercontinental range since 1999. The most recent test, in June 2014, was a success, but that followed three straight failures. The system has evolved from the multibillion-dollar effort triggered by President Ronald Reagan’s 1983 push for a “Star Wars” solution to ballistic missile threats during the Cold War — when the Soviet Union was the only major worry.

North Korea is now the focus of U.S. efforts because its leader, Kim Jong Un, has vowed to field a nuclear-armed missile capable of reaching American territory. He has yet to test an ICBM, but Pentagon officials believe he is speeding in that direction. Marine Lt. Gen. Vincent Stewart, director of the Defense Intelligence Agency, said that “left unchecked,” Kim will eventually succeed.

The basic defensive idea is to fire a rocket into space upon warning of a hostile missile launch. The rocket releases a 150-centimeter long device that uses internal guidance systems to steer into the path of the coming missile’s warhead, destroying it by force of impact.  An interceptor rocket will be launched from an underground silo and soar toward the target, which will be fired from a test range on in the Pacific.

The target will be a custom-made missile meant to simulate an ICBM, meaning it will fly faster than missiles used in previous intercept tests, according to Christopher Johnson, spokesman for the Missile Defense Agency. The target is not a mock-up of an actual North Korean ICBM. “We conduct increasingly complex test scenarios as the program matures and advances,” Johnson said. “Testing against an ICBM-type threat is the next step in that process.”

While it wasn’t scheduled with the expectation of an imminent North Korean missile threat, the military will closely watch whether it shows progress toward the stated goal of being able to reliably shoot down a small number of ICBMs targeting the United States. The Pentagon is thirsting for a success story amid growing fears about North Korea’s escalating capability.

The interceptor system has been in place since 2004, but it has never been used in combat or fully tested. There currently are 32 interceptors in silos in Alaska and four north of Los Angeles. The Pentagon says it will have eight more, for a total of 44, by the end of 2017.

In its 2018 budget presented to Congress, the Pentagon proposed spending $7.9 billion on missile defense, including $1.5 billion for the Ground-based Midcourse Defense program.

Other elements of that effort include the Patriot designed to shoot down short-range ballistic missiles and the Terminal High Altitude Area Defense (THAAD), which the U.S. has installed in South Korea as a defense against medium-range North Korean missiles.

President Donald Trump recently ordered the Pentagon to undertake a ballistic missile defense review. Some experts argue the current strategy for shooting down ICBM-range missiles, focused on the silo-based interceptors, is overly expensive and inadequate. They say a more fruitful approach would be to destroy or disable such missiles before they can be launched, possibly by cyberattack.
