National Missile Defense, Inflated Fabric Radome for Sea-Based X-Band Radar

United States


Raytheon Company



The Sea-Based X-Band Radar (SBX) is a major component of the Ground-Based Mid-Course Missile Defense (GMD). The SBX is a mechanically steerable, phased-array radar antenna mounted on a self-propelled, ocean-going, semi-submersible platform. This advanced X-Band Radar (XBR) is housed within an inflated radome designed to protect the radar from the harsh sea environment and cyclones of the Pacific Ocean. SGH worked with Raytheon and ILC Dover to design the radome.
