Raytheon has won $136 million modification contract to exercise an option for Air and Missile Defense Radar Program (AMDR) low rate initial production (LRIP).

The LRIP unit will be deployed on a DDG Flight III class ship. Work is expected to be completed by April 2021, the US Department of Defense said in a statement Thursday.

The Air and Missile Defense Radar – AN/SPY-6(V) – is the Navy's next generation integrated air and missile defense radar. It is advancing through development and on track for the DDG-51 Flight III destroyer.

The radar significantly enhances the ships’ ability to detect air and surface targets as well as the ever-proliferating ballistic missile threats.

The system is built with individual ‘building blocks’ called Radar Modular Assemblies. Each RMA is a self-contained radar in a 2’x2’x2’ box. These individual radar RMAs can stack together to form any size array to fit the mission requirements of any ship, making AMDR the Navy’s first truly scalable radar.

For the DDG 51 Flight III destroyer, the SPY-6(V) AMDR will feature: 1. 37 RMAs – which is equivalent to SPY-1D(V) +15 dB; Meaning, SPY-6 can see a target of half the size at twice the distance of today’s radar.

2. Four array faces to provide full-time, 360° situational awareness. Each face is 14’ x 14’ – which is roughly the same dimension as today’s SPY-1D(V) radar.
