Reliable and robust missile defense technology
We provide the critical communication links that ensure the Missile Defense Agency's (MDA) Ground-based Midcourse Defense (GMD) interceptors receive precise threat targeting data throughout their course into space to engage the incoming threat, and the GMD command receives complete assessments of the effectiveness of threat engagement.
L3Harris provides strategic SATCOM terminals via the Modernization of Enterprise Terminals (MET) program to the GMD ground sites, and provides shipboard SATCOM terminals to the Sea-based X-band Radar (SBX), both key elements of the GMD Communications Network (GCN). Our protected Anti-Scintillation Anti-Jam Wideband Netcentric System (PAAWNS) modems ensure these critical data links remain fully operational even in the presence of jamming and high altitude nuclear events.
The benefits of our protected SATCOM solutions include:
- Provides critical targeting data to GMD interceptors, and interceptor status data to ground fire control at all stages of flight
- Assures robust communications in the presence of jamming, interference, and nuclear events: high altitude electromagnetic pulse (HEMP) hardened and impervious to scintillation
- Achieves reliability and availability objectives through an affordable development, operations and sustainment implementation
In addition to our strategic terminals and PAAWNS modem, our In-Flight Interceptor Communications System (IFICS) Data Terminal (IDT) tracks the fast-moving Ground Based Interceptor (GBI) to provide essential targeting data updates and receive status from the GBI and its payload Kill Vehicle (KV).
L3Harris is implementing improved modems and system upgrades in support of the replacement GBI and KV capabilities, as well as providing 24/7 operations and sustainment support to the fielded systems to ensure that the GMD system is always on duty and ready to engage.
