Northrop to Integrate Sonar onto L3Harris Small-Class UUV

Northrop Grumman said it will integrate its µSAS (pronounced “micro-sas”) sonar onto L3Harris Iver4 unmanned undersea vehicle (UUV) for a 12-month test period for the Defense Innovation Unit’s (DIU) next generation small-class UUV program.

Integrated onto a 9-inch diameter, 99-inch long, 200-pound UUV, the installation will occur at L3Harris’ Fall River, Massachusetts facility and the system will be tested in San Diego, California by the U.S. Navy.

The integration of synthetic aperture sonar on a small diameter UUV is a significant step forward in small class vehicle capability.

“The Northrop Grumman µSAS advanced imaging sonar is a minehunting force multiplier designed specifically for UUVs,” said Alan Lytle, vice president, undersea systems, Northrop Grumman. “This integration will help to deliver a significant increase in the platform’s ability to detect objects on the seafloor and in the water column.”

“The Iver4, integrated with µSAS, is a major advancement in small-class UUV capability for the warfighter,” said Daryl Slocum, president and general manager, unmanned maritime systems, L3Harris.
