US Navy EASR passes preliminary design review

The U.S. Navy, together with Raytheon, completed the preliminary design review (PDR) for the new Enterprise Air Surveillance Radar, confirming system development is on track for delivery to the designated ship classes.

EASR is the U.S. Navy’s advanced radar for aircraft carriers and amphibious warfare ships, providing simultaneous anti-air warfare, anti-surface warfare, and air traffic control mission capabilities.

EASR is the replacement for the Volume Search Radar for the CVN 78 class, and the AN/SPS-48 and AN/SPS-49 radar systems for numerous ship classes. It delivers increased performance, higher reliability and sustainability, and lower total ownership cost than the radars it replaces.

The preliminary design review followed several EASR milestones completed as planned on the development schedule, including the combined systems requirements and system functional reviews, and the integrated baseline review.

“Each EASR development milestone brings us closer to providing this needed mission capability to our sailors and marines deployed on aircraft carriers and amphibious ships,” said U.S. Navy Capt. Seiko Okano, major program manager for Above Water Sensors, Program Executive Office Integrated Warfare Systems. “As the PDR confirmed, the technical and design maturity of this advanced radar is right where it should be.”

The PDR validated Raytheon’s scaled design leveraging the AN/SPY-6(V) Air and Missile Defense Radar, configured into a rotating and a fixed face variant to match the missions of the multiple ship classes. EASR is built on Radar Modular Assembly technology which has been matured through development – and recent test successes – of AN/SPY-6 for the DDG 51 Flight III destroyers. Each RMA is a self-contained radar in a 2’x2’x2′ box. These individual radars can integrate together to form arrays of various sizes.
