Raytheon Air and Missile Defense vice-president Dr Mitch Stevison said: "Raytheon is continually working to increase the overall reliability of the highly dependable SM-3, reflecting the MDA’s commitment to mature this capability for the defence of our nation, deployed forces, and our allies.
"SM-3 continues to demonstrate its versatility and reliability, providing an extraordinary level of protection from sea or land."
The test validated in-flight performance of the upgrade has already passed ground testing. The upgrade will be integrated into the current missile production line.
The SM-3 has the ability to destroy incoming ballistic missile threats in space using sheer impact, equivalent to a 10t truck travelling at 600mph, according to Raytheon.
