The U.S. Navy successfully executed four flight tests of the surface-to-air Standard Missile-6 Block I (SM-6 Blk I) off the Hawaiian coast between April 6 and 13. These tests marked the next step toward the SM-6 Blk I's achievement of Full Operational Capability. In addition, these are the first tests with the latest SM-6 Blk I software that includes air
warfare, ballistic missile sea based terminal defense, and anti-surface warfare capabilities.
