DARPA has awarded Phase 2 contracts to continue the Manta Ray program that began in 2020. The effort seeks to demonstrate innovative technologies allowing payload-capable autonomous unmanned underwater vehicles (UUVs) to operate on long-duration, long-range missions in ocean environments. The two prime contractors, Northrop Grumman Systems Corporation and Martin Defense Group, are each developing unique full-scale demonstration vehicles.
