Enterprise Air Surveillance Radar (EASR) Antenna Installed on US Navy Ship for First Time

The Enterprise Air Surveillance Radar (EASR) antenna landed on the future USS Richard M. McCool Jr. (LPD 29), Jan.16, 2023. This marks the completion of EASR system deliveries for what will be the first LPD 17 Class ship and the first U.S. Navy install and activation of the SPY-6(V)2, rotating variant, S-Band radar. SPY-6(V)2 provides the U.S. Navy with a common hardware variant for carrier and amphibious ships. In addition to providing hardware and software commonality, the radar will also contribute to increased engagement and overall ship self-defense. As with all incremental technology enhancements, the U.S. Navy is applying an increased focus to ensure that the system is provided on schedule, integrated into the ship/combat system and activated.

“The progress made is a testament to the collaboration across multiple organizations in bringing this next-generation radar to the LPD program. The Navy and our industry partners look forward to systems activation and testing as LPD 29 continues on the path to sea trials later this year,” said Capt. Cedric J. McNeal, Amphibious Warfare Program Manager, Program Executive Office (PEO Ships).

Raytheon Missiles & Defense and the U.S. Navy completed engineering and manufacturing developmental testing for EASR in March 2020. In July 2020, the Navy awarded the company a $126 million contract to produce four SPY-6(V)2 rotators and two SPY-6(V)3 fixed-faced radars. In 2021, the U.S. Navy and Raytheon Missiles & Defense, a Raytheon Technologies business, completed a series of tests on the Enterprise Air Surveillance Radar at the Navy’s Wallops Island Test Facility in Virgina. The tests validated the performance of EASR’s two variants: the SPY-6(V)2 rotating and SPY-6(V)3 fixed-face radars.

Ultimately, EASR will be made ready as an integral sensor in an integrated Ship Self-Defense System to support the ship’s employment. As one of the Defense Department’s largest acquisition organizations, PEO Ships is responsible for executing the development and procurement of all destroyers, amphibious ships, special mission and support ships, boats and craft. The AN/SPY-6(V)2 will be installed on amphibious assault ships and Nimitz class carriers. The AN/SPY-6(V)3 will be incorporated on Ford class aircraft carriers and is compatible with frigates for international navies. AN/SPY-6(V)3 will be a centerpiece of the U.S. Navy’s new Constellation class frigates (FFG 62).
