SPY-6 consists of Radar Modular Assemblies spanning two square feet and is designed to detect complex threats.
"It's 100 times more sensitive than the existing SPY-1. It gives you that much more range, and that means the Navy can counteract that much quicker," said Mike Mills, SPY-6 program director at Raytheon.
The Navy's Flight IIA ships will receive a 24-block configuration of SPY-6 while the Flight III destroyers will get a version with 37 RMA blocks.
Mills noted that most of the platform's detection features will remain as classified information.
