The XBR is a high-powered, phased-array radar designed to meet near-term ballistic missile threats from rogue states.

The X-Band Radar (XBR) is a large, phased-array fire control sensor, featuring precision discrimination and interceptor support. It is mounted on a dynamic pedestal and mechanically slewed to provide hemispheric coverage. XBR derives its configuration from NMD Ground Based Radar Prototype (GBR-P) architecture and leverages a 70 percent reuse of GBR-P software. It uses components similar to those of the GBR-P and THAAD Radar, incorporating the enhancements necessary to meet its more demanding NMD requirements.

The XBR can be populated with 69,632 transmit/receive (T/R) modules. Upgrading the signal/data processing software and adding advanced processing techniques will address future threats with significant cost savings.
