Ghost Shark and Manta Ray: Australia and US unveil undersea drones | CNN Business

Ghost Shark and Manta Ray protect the undersea realm. Sounds like the plot of a future Marvel movie, but in actual fact, it’s what could be the future of Pacific naval defenses.
Ghost Shark and Manta Ray are the names of prototype uncrewed underwater vehicles – UUVs or drones – introduced recently by Australia and the United States respectively.
Experts say the submersibles could represent the future of undersea warfare, showing the ability to exert power while minimizing the danger to human life.
