'Ghost Shark and Manta Ray: Australia, US launch next-gen advanced drones'

The future of naval defenses in the Pacific may soon resemble a high-stakes technology thriller, with characters called Ghost Shark and Manta Ray. These are not characters from a future blockbuster, but rather the names of the newest uncrewed underwater vehicles (UUVs) or drones, revealed by Australia and the United States. According to a report, Ghost Shark and Manta Ray are prototypes that aim to redefine undersea warfare.
