The Early Warning Radar provides early detection and precise tracking of incoming ballistic missiles, as well as quick, accurate determination of threat versus non-threat objects. It is the cornerstone of missile defense for the U.S. and allies, and it’s easy to see why.
The radar, also called EWR, can track more than 1,000 objects at the same time from more than 5,000 kilometers away. It can tell ballistic missile and air-breathing threats from non-threats, and it can deter potential attacks.
Here’s why the EWR, built by Raytheon Missiles & Defense, a Raytheon Technologies business, stands apart from other sensors. It performs four missions:
• Early warning and attribution: The EWR can warn of a missile threat and find its launch point up to 20 minutes before it happens. That creates a deterrent effect; adversaries know they are not hidden, even from far away, and that a retaliatory attack is possible.
• Integrated air and missile defense: The radar provides persistent, 360-degree defense, and gathers precise tracking data and feeds it into integrated air and missile defense systems, improving their effectiveness.
• Space situational surveillance: There are thousands of objects in lower Earth orbit, and their paths make them look like tactical ballistic missiles. The EWR’s long range allows horizon-to-horizon tracking to ensure threatening objects are addressed and non-threatening objects are not. With 6,000 satellites in orbit keeping satellites safe during commercial flights is also vital.
• Volume air surveillance and tracking: Commercial airspace is increasing in density, making it especially important to tell the difference between friendly and adversary aircraft. The EWR makes that distinction, while helping coordinate, communicate and prioritize threats.
EWR is the perfect complement to existing IAMD assets in countries like the United Arab Emirates, where you have great capabilities against current threats. But there are certain gaps, and EWR fills those gaps.
As a systems integrator, Raytheon Missiles & Defense has ensured EWR is interoperable with the AN/TPY-2 radar, Global Patriot Solutions, Lower Tier Air and Missile Defense Sensor, or LTAMDS, and the Terminal High Altitude Area Defense, or THAAD – and has done so in a cyber-hardened environment.
The radar is really a security blanket. You can continue to operate and maintain not only EWR, but also your other radars without sacrificing security. And adversaries will know that because you’re radiating the whole time.
