Boeing completes missile defense silo

Seattle Post Intelligencer

Boeing, industry teammates and the U.S. Missile Defense Agency have completed construction of a second interceptor test silo for the Ground-based Midcourse Defense system at Vandenberg Air Force Base in California …

Because a silo needs to be refurbished after its hot-burning interceptor is fired, having two underground test silos will allow one to support testing while the other is being refurbished, Boeing said. It said the new silo can be configured for testing or tactical operations. Vandenberg’s first test silo has been used in tests since 2006.

The Huntsville, Ala.-based Ground-based Midcourse Defense program has deployed more than 20 operational interceptors at Vandenberg and Fort Greely, Alaska, to defend against long-range ballistic missile threats.
