The US Navy's Manta Ray submarine, a prototype underwater drone developed by Northrop Grumman, was recently spotted at the Port Hueneme naval base in California. Named after the sea creature, the Manta Ray can operate deep underwater in low-power mode for extended periods without refueling. This advanced submarine, designed with modular features for easy transport, is part of the US's strategic efforts to counter submarine threats from Russia and China. Its recent sighting and disappearance have sparked widespread interest and speculation.
