Bill asks Pentagon to examine more options for stopping North Korean missiles

A bill signed by President Donald Trump on Monday asks the Pentagon to pursue more options for defeating U.S.-bound North Korean missiles by using radar and more missiles to spot and shoot down inbound threats.

The National Defense Authorization Act gives the Pentagon $716 billion, with almost $10 billion going to the Missile Defense Agency to fund the expansion of missile defences, emphasizing the need to stop any North Korean or Iranian attacks.

The military is already exploring whether the United States can add another layer to defences to those already in place for intercepting incoming missiles in flight, Keith Englander, the U.S. Missile Defense Agency`s director for engineering, said at the Space and Missile Defense Symposium in Huntsville, Alabama, last week.

The Missile Defense Agency`s head, Lieutenant General Samuel Greaves, has said he wants to integrate the Aegis Combat System into the current ICBM defences of the U.S. homeland. The Aegis system, mainly found on ships, could be fitted with the Standard Missile 3 Block IIA (SM-3 IIA) interceptors that are being developed in a joint venture between Raytheon Co and Japan`s Mitsubishi Heavy Industries Ltd .

The Lockheed Martin Corp-made Aegis system is currently deployed aboard 36 U.S. Navy ships, as well as at the Pacific Missile Range Facility on Hawaii.

If given the new mission, the ships could patrol the Pacific Ocean and augment the network of Ground-Based Midcourse Defense interceptor missiles in Alaska and California that protect the nation from intercontinental ballistic missile (ICBM) attacks.

This is one of several avenues the Pentagon is studying to knock down inbound missiles. These include shooting the missile down soon after takeoff, stopping it in space as it flies above the Earth`s atmosphere, and killing it soon after it re-enters the atmosphere before hitting its target.

Concern about U.S. missile defences has grown with the escalating threat from North Korea. Last year, North Korea conducted about a dozen missile tests, including the launch of a suspected ICBM that could hit the U.S. mainland and the test of a purported hydrogen bomb.

North Korea and the United States are struggling to agree on how to bring about the North`s denuclearisation, after Kim vowed to work toward that goal at a landmark summit in June in Singapore with Trump.

The potential new defences must first be tested to make sure the intercepting missile can take out what could be an ICBM fired by Pyongyang.

In a previous spending bill, Congress mandated that the Missile Defense Agency perform an intercept test with the SM-3 IIA missile against an ICBM by the end of 2020.

Last year, Reuters reported that the Pentagon was investigating adding a missile defence layer under the Ground-Based Midcourse Defense system.

In May 2017, the Missile Defense Agency held its first live-fire test of the Ground-Based Midcourse Defense against a simulated ICBM, and hailed the successful intercept as an "incredible accomplishment."
