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 Navy is applying an increased focus to ensure that the system is provided on schedule, integrated into the ship/combat system, and activated. Ultimately, EASR will be made ready as an integral sensor in an integrated Ship Self-Defense System to support the ship’s employment.
