Raytheon's Enterprise Air Surveillance Radar to Begin System-Level Testing

Raytheon's Enterprise Air Surveillance Radar (EASR), the newest sensor in the U.S. Navy's SPY-6 family of radars, recently completed subsystem testing at Raytheon's Near Field Range in Sudbury, Massachusetts. The 6' x 6' rotating array was wrapped, loaded onto a flatbed truck and eventually crane-lifted onto a 100-foot test tower at the Surface Combat Systems Center at Wallops Island, Virginia. Once up and running, the radar will undergo system-level testing, tracking a variety of aircraft through the end of 2019.

EASR is the Navy's next-generation radar for aircraft carriers and amphibious warfare ships that provides simultaneous anti-air and anti-surface warfare, electronic protection and air traffic control capabilities.

Raytheon is building two variants of EASR: a single-face rotating array designated AN/SPY-6(V)2 for amphibious assault ships and Nimitz class carriers, and a three fixed-face array designated AN/SPY-6(V)3 for Ford-class aircraft carriers and the future FFG(X) guided missile frigates.

Both versions of EASR are built on scalable Radar Modular Assembly technology as well as a software baseline that has been matured through development and recent test successes of AN/SPY-6(V)1 the U.S. Navy's program of record for the DDG 51 Flight III destroyers. Each RMA is a self-contained radar in a 2' x 2' x 2' box. These individual radars can integrate together to form arrays of various sizes to address any mission on any ship. EASR also adds air traffic control and weather capabilities to the mature SPY-6 software baseline.

Upon completion of system-level testing in Q4 2019, EASR will shift from the engineering and manufacturing development phase to the production phase. The 1st delivery of AN/SPY-6(V)2 to LHA-8, the America Class Amphibious Assault Ship, is on plan for 2021.
