The contractor for the SM-3 Block IB missiles is Raytheon Missile Systems.
The SM-3 Block IIA is being developed cooperatively by the US and Japan and operates as part of the AEGIS Ballistic Missile Defence system, the naval component of the US Ballistic Missile Defence System.
The SM-3 interceptor is already a critical part of a NATO missile defence system in Europe, with interceptors deployed on US Navy ships off the continent's coast, according to the manufacturer Raytheon.
