Raytheon and US Navy conduct PDR for new Enterprise Air Surveillance Radar


The US Navy has collaborated with Raytheon to conduct a preliminary design review (PDR) of the new Enterprise Air Surveillance Radar (EASR).

The PDR confirms that the radar’s system development is on track to be delivered to the US Navy’s designated ship classes.

EASR is being developed as an advanced radar system, and will be deployed on the US Navy’s aircraft carriers and amphibious warfare vessels in order to offer simultaneous anti-air warfare, anti-surface warfare, and air traffic control mission capabilities.

The system's installation is intended to provide enhanced performance, higher reliability and sustainability, while reducing the total ownership cost of previous radars.

EASR is set to replace the Volume Search Radar for the CVN 78 class, and the AN / SPS-48 and AN / SPS-49 radar systems for a wide range of other ship classes.

Programme Executive Office Integrated Warfare Systems Above Water Sensors major programme manager US Navy captain Seiko Okano said: “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.

“As the PDR confirmed, the technical and design maturity of this advanced radar is right where it should be.”

The new air surveillance radar is designed on Radar Modular Assembly (RMA) technology, which has been matured through development and recent test successes of the US Navy’s AN / SPY-6 air and missile defence 3D radar for the DDG 51 Flight III destroyers.

Each RMA is a self-contained radar housed in a 2ft by 2ft by 2ft box, and the systems can be linked together to form radar chains of various sizes.

The EASR will be offered to the US Navy in two variants: Variant one, which will be a single face, rotating radar, and Variant two, which is a three face, fixed-array unit.
