U.S. plans to go ahead with missile defense system despite test failure

The U.S. military will continue with plans to deploy a missile system in Alaska, despite a recent test failure by an interceptor missile, a Pentagon official said on Tuesday.

George Little, the Pentagon's spokesman, said the unsuccessful test on Friday of a ground based interceptor would not result in scrapping the plan to deploy the weapons in Alaska, AFP reports.

"The test on Friday was not a success and it's being reviewed to see what went wrong," Little said, according to AFP. "But we maintain that we have a robust defense system in place to defend the United States and her allies from a range of threats. There are no plans to change our expansion to 44 ground based interceptors."

In March, the Pentagon announced plans to deploy 14 additional GBI missiles at the Alaska-based Fort Greely by the year 2017. At the time, Defense Secretary Chuck Hagel said the U.S. needed to stay ahead of the increased missile capabilities of Iran and North Korea.

There are currently 30 deployed missiles in California in Alaska. The new deployment would result in nearly a 50 percent increase in GBIs in North America.

Since 2010, four GBI tests, each of which cost approximately $70 million, all failed to achieve their objectives, AFP reports.
