Raytheon Wins $126M to Build Enterprise Air Surveillance Radars for US Navy

The Pentagon on Friday said Raytheon won $125.88 million for Enterprise Air Surveillance Radar (EASR) low rate initial production (LRIP).

EASR is the newest sensor in the Navy's SPY-6 family of radars. It provides simultaneous anti-air and anti-surface warfare, electronic protection and air traffic control for aircraft carriers and amphibious warfare ships. Two variants of EASR are being built: 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.

The modification contract exercises option for the production of six EASR LRIP units; four AN/SPY-6(V)2 (air and missile defense radar) EASR rotator LRIP units; and two AN/SPY-6(V)3 EASR fixed-faced LRIP units.  The AN/SPY-6(V)2 EASR rotator LRIP units will be deployed on the USS Bougainville (LHA-8); USS John C. Stennis (CVN-74); USS Richard M. McCool Jr. (LPD-29); and USS Harrisburg (LPD-30).  The AN/SPY-6(V)3 EASR fixed-faced LRIP units will be deployed on USS John F. Kennedy (CVN-79); and USS Brooke (FFG-1), Pentagon said in a release.

Both versions of EASR are built on scalable Radar Modular Assembly, or RMA, technology as well as a software baseline that has been matured through development and 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.

Work pertaining to the contract is expected to be completed by January 2023.
