US Navy Deploys Raytheon’s Second-Generation SM-3 Block IB

In partnership with the Missile Defense Agency, the U.S. Navy deployed the second-generation Standard Missile-3 Block IB made by Raytheon Company for the first time, initiating the second phase of the Phased Adaptive Approach.

In 2009, the administration announced the U.S. decision to adopt a new, more flexible approach to missile defense of both the U.S. and Europe. The Phased Adaptive Approach (PAA) Phase 1 began in March 2011 when the USS Monterey deployed carrying SM-3 Block IAs.

In Oct. 2013, ground broke in Romania on the first operational Aegis Ashore site, which will be capable of launching SM-3 Block IAs, IBs and IIAs. The site continues on track for 2015 deployment as part of PAA Phase 2. Along with deployed Aegis Ballistic Missile Defense ships, Romania’s Aegis Ashore site will provide additional ballistic missile coverage of NATO countries. The first Aegis Ashore test with the SM-3 Block IB and upgraded Aegis BMD Weapons System will take place this year at the Pacific Missile Range Facility, Kauai, Hawaii.
