The Enterprise Air Surveillance Radar (EASR) under development for the US Navy's aircraft carriers and amphibious warfare ships has completed its preliminary design review (PDR), Raytheon announced on 26 April.
The successful PDR confirms that the radar is on track for delivery to designated ship classes. It validated Raytheon's scaled design, which leverages 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 designed to provide aircraft carriers and amphibious ships with anti-air warfare, anti-surface warfare and air traffic control mission capabilities. It is built on radar modular assembly (RMA) technology, which has been matured through development of AN/SPY-6 for the DDG 51 Flight III destroyers. Each RMA is a self-contained radar in a 2'x2'x2' box which can be integrated together to form arrays of various sizes.
EASR will replace the Volume Search Radar for the CVN 78 class, and the AN/SPS-48 and AN/SPS-49 radar systems for numerous ship classes.
The radar has already undergone systems requirements and system functional reviews and an integrated baseline review.
