Northrop Grumman has introduced Valen, the newest multifunction active electronically scanned array (AESA) in the company’s advanced sensing portfolio. Valen's next generation capabilities are ready to deliver the tactical edge to U.S. and allied warfighters.

The company describes the new wideband array as "lighter, smaller and more affordable, combining radar, electronic warfare and communications into one elegant design for crewed and uncrewed platforms" with the following capabilities:

Company-Funded Innovation: Funded entirely by Northrop Grumman, Valen builds upon generations of combat-proven AESA technology.
Accelerated Production: Valen is 3D-printed and digitally designed, reducing its production timeline. Northrop Grumman continues to deliver at the speed of innovation.
Unmatched Performance Excellence: Valen's exceptional performance is powered by Northrop Grumman Microelectronics Center’s advanced packaging techniques, which combine many different semiconductor parts into one micro-sized package, so the device works faster, stays cooler and uses less power, all within a smaller footprint.
Open Architecture: Built with the latest open-architecture standards, Valen’s hardware and software unites the power of advanced sensor capabilities from across Northrop Grumman and enables rapid updates.
Next-Level Detection: An AESA is a digitally controlled array that uses antennas and sensors to provide rapid detection, tracking and imaging capabilities in any direction without the need for mechanical movement.

“Our warfighters require advanced situational awareness no matter what platform they’re operating. Valen’s design embodies the future of warfare—integrating cutting-edge technology, adaptability and affordability to enable quick decision making and effective mission execution. Valen’s compact, lightweight design cuts production time, delivering a highly capable product to the field faster," said Krys Moen, Vice President, Advanced Mission Capabilities, Northrop Grumman.
