Northrop Grumman is great at building military airplanes. So why does it want to go back to doing something it's not as good at?

DARPA has successfully completed the first in-water testing of the Manta Ray uncrewed underwater vehicle (UUV) prototype, developed by Northrop Grumman.

Northrop Grumman’s Manta Ray uncrewed underwater vehicle (UUV) prototype has completed in-water testing off the California coast.

The Manta Ray prototype UUV built by Northrop Grumman for DARPA completed in-water testing off Southern California in February/March 2024.

The uncrewed underwater vehicle is designed for long-range, long-duration operations.

The aim of the Manta Ray is to pave the way for the deployment of payload-capable UUVs that can operate for long durations.

“I think it is striking in its size and scale, even for those folks that have been there throughout the design process.”
