DARPA's MANTA RAY submersible

On April 8, Northrop Grumman officially unveiled its new prototype deep sea drone, the Manta Ray uncrewed underwater vehicle (UUV). This new undersea drone is designed to conduct extended-duration autonomous operations at long ranges with minimal need for human support, making it uniquely suited for a wide variety of undersea scientific and potential combat operations.

But arguably, it’s most potent use could be as an element of America’s anti-submarine warfare strategy.
