Thanks to Raytheon for this:

The SPY-6 family is integrated, meaning it can defend against ballistic missiles, cruise missiles, hostile aircraft and surface ships simultaneously. And it offers many advantages over legacy radars, such as greater detection range, increased sensitivity and more accurate discrimination.

The U.S. Navy will outfit every new surface ship in its fleet – from small patrol vessels to mammoth aircraft carriers – with new radars that can find and track enemy missiles and planes simultaneously, under a $651 million contract with Raytheon Missiles & Defense. The contract includes options, if exercised, that would bring the cumulative value of the award to $3.16 billion.

With the award, Raytheon Missiles & Defense, a Raytheon Technologies business, will provide hardware, production and sustainment for the SPY-6 family of radars.

“There is no other radar with the surface maritime capabilities of SPY-6, and this award highlights the importance of its design and future production for the Navy,” said Wes Kremer, president of Raytheon Missiles & Defense. “SPY-6 is the most advanced naval radar in existence, and it will provide a giant leap forward in capability for the military for decades to come.”

The radars will allow sailors to find threats, including hypersonic weapons, at greater distances, and to react faster to them.

“It’s a vast improvement over what the U.S. Navy currently has on it ships,” said Kim Ernzen, Naval Power president at Raytheon Missiles & Defense. “It’s like going from a pen light to a huge flashlight.”

In 2021, the Navy began installing the first SPY-6 radar on its new, high-tech Aegis Flight III, the USS Jack H. Lucas (DDG 125).

Each SPY-6 radar for the DDG class ship includes four arrays, a power system, a cooling system, and a back-end processor to compute array signals.

Scalable for the future

SPY-6 is also the Navy’s first truly scalable radar, making it easy to configure to any type of ship.

It’s built with individual ‘building blocks’ called radar modular assemblies. Each RMA is a self-contained radar antenna in a 2’x2’x2’ box. The RMAs can stack together to form an array of nearly any size to fit the mission requirements of any ship.

“We can scale it for frigates and other classes of ships,” said Scott Spence, program area director for naval radars at Raytheon Missiles & Defense. “And, we can add capabilities across all those platforms very seamlessly and quickly.”

By the end of the contract, the radar will be on more than 45 ships across the Navy.

The radars’ common software baseline makes them easy to upgrade, without the need to install new hardware. Under a separate integration and production support contract, Raytheon Missiles & Defense will deliver software upgrades over the SPY-6 family’s lifetime.

Meeting high-rate production

Raytheon Missiles & Defense has invested more than $500 million in infrastructure and capacity enhancements for SPY-6, including advanced automation technology at its 30,000 square-foot Radar Development Facility. The business used its Immersive Design Center to configure the factory and refine processes to deliver faster and better.

“We’ve completely streamlined the building and testing of SPY-6 to meet high-rate production,” Spence said.

And those same types of efficiencies are shared among suppliers, which provide 75 percent of the radar systems integrated by Raytheon.

“There’s a great deal of work across our supply base, across the country, to make this family of radars a success,” Spence said.

Sustaining with innovation

While meeting production demands, Raytheon Missiles & Defense continues to work with the Navy to improve the radar.

In 2021, the business and Office of Naval Research tested new distributed sensing software for the SPY-6 radar. The demonstration supports the Navy’s goal of creating distributed sensing networks to defend against evolving threats.

Earlier, Raytheon Missiles & Defense and the Navy completed testing on the Enterprise Air Surveillance Radar (EASR) at the U.S. Navy’s Wallops Island Test Facility in Virginia.

The SPY-6(V)2 rotating radar and SPY-6(V)3 fixed-face radar are known together as EASR. The tests focused on anti-air warfare and air traffic control capabilities, weather operations, and power systems for both radars.

The EASR will replace single-function legacy radars and improve range and performance.
