SIMI VALLEY, Calif (Reuters) - The U.S. agency tasked with protecting the country from missile attacks is scouting the West Coast for places to deploy new anti-missile defenses, two Congressmen said on Saturday, as North Korea s missile tests raise concerns about how the United States would defend itself from an attack. West Coast defenses would likely include Terminal High Altitude Area Defense (THAAD) anti-ballistic missiles, similar to those deployed in South Korea to protect against a potential North Korean attack.   The accelerated pace of North Korea s ballistic missile testing program in 2017 and the likelihood the North Korean military could hit the U.S. mainland with a nuclear payload in the next few years has raised the pressure on the United States government to build-up missile defenses.  On Wednesday, North Korea tested a new type of intercontinental ballistic missile (ICBM) that can fly over 13,000 km (8,080 miles), placing Washington within target range, South Korea said on Friday. Republican party Congressman Mike Rogers, who sits on the House Armed Services Committee and chairs the Strategic Forces Subcommittee which oversees missile defense, said the Missile Defense Agency (MDA), was aiming to install extra defenses at West Coast sites. The funding for the system does not appear in the 2018 defense budget plan indicating potential deployment is further off.  It s just a matter of the location, and the MDA making a recommendation as to which site meets their criteria for location, but also the environmental impact,  the Alabama Congressman told Reuters during an interview on the sidelines of the annual Reagan National Defense Forum in southern California. After this story was published Congressman Rogers told Reuters in a statement he was  unaware of any effort by the Department of Defense to locate additional intermediate missile defense assets on the West Coast.  He added that his earlier comments to Reuters  should not be interpreted as confirmation of such an effort.  Reuters global head of communications, Abbe Serphos, said  We stand by our story.   When asked about the plan, MDA Deputy Director Rear Admiral Jon Hill  said in a statement:  The Missile Defense Agency has received no tasking to site the Terminal High Altitude Air Defense System on the West Coast.  The MDA is a unit of the U.S. Defense Department. Congressman Rogers did not reveal the exact locations the agency is considering but said several sites are  competing  for the missile defense installations. Rogers and Congressman Adam Smith, a Democrat representing the 9th District of Washington, said the government was considering installing the THAAD anti-missile system made by aerospace giant Lockheed Martin Corp, at west coast sites.  The Congressmen said the number of sites that may ultimately be deployed had yet to be determined. THAAD is a ground-based regional missile defense system designed to shoot down short-, medium- and intermediate-range ballistic missiles and takes only a matter of weeks to install.  In addition to the two THAAD systems deployed in South Korea and Guam in the Pacific, the U.S. has seven other THAAD systems. While some of the existing missiles are based in Fort Bliss, Texas, the system is highly mobile and current locations are not disclosed.  A Lockheed Martin representative declined to comment on specific THAAD deployments, but added that the company  is ready to support the Missile Defense Agency and the United States government in their ballistic missile defense efforts.  He added that testing and deployment of assets is a government decision. In July, the United States tested THAAD missile defenses and shot down a simulated, incoming intermediate-range ballistic missile (IRBM). The successful test adds to the credibility of the U.S. military s missile defense program, which has come under intense scrutiny in recent years due in part to test delays and failures. Currently, the continental United States is primarily shielded by the Ground-based Midcourse Defense system (GMD) in Alaska and California as well as the Aegis system deployed aboard U.S. Navy ships. The THAAD system has a far higher testing success rate than the GMD. The MDA told Congress in June that it planned to deliver 52 more THAAD interceptors to the U.S. Army between October 2017 and September 2018, bringing total deliveries to 210 since May 2011. North Korea s latest missile test puts the U.S. capital within range, but Pyongyang still needs to prove it has mastered critical missile technology, such as re-entry, terminal stage guidance and warhead activation, South Korea said on Friday.
