Northrop Grumman has introduced Valen, a new multifunction active electronically scanned array (AESA) sensor designed for crewed and uncrewed platforms across air and space domains.
Announced on 16 February 2026 in Linthicum, Maryland, Valen combines radar, electronic warfare and communications functions into a single wideband array. The company said the system is lighter and smaller than previous designs and can be integrated into new platforms or used to upgrade existing ones.
According to Northrop Grumman, Valen was funded internally and developed using digital design tools and 3D printing to shorten production timelines. The system also uses advanced semiconductor packaging techniques from the company’s Microelectronics Center to consolidate multiple components into a compact unit.
An AESA system uses a digitally controlled array of antennas to provide detection, tracking and imaging without mechanical movement. Northrop Grumman said Valen is built using open-architecture standards to allow hardware and software updates.

The company confirmed that Valen has completed flight testing aboard Northrop Grumman-owned CRJ-700 aircraft.
Krys Moen, vice president, advanced mission capabilities, Northrop Grumman, said: “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.”
Northrop Grumman said the system is part of its advanced sensing portfolio and is intended for use by U.S. and allied forces.
