The US military appears to have a new underwater drone called Stingray, located at the Port Hueneme Naval Base in California, as seen on Google Maps. The unmanned underwater vehicle, designed by Northrop Grumman, is part of a program by the Defense Advanced Research Projects Agency for various Navy purposes. It is shaped like a manta ray and is part of a fleet of UUVs being developed by the agency.
The agency recently conducted successful tests of the Manta Ray prototype between February and March off the coast of Southern California. The tests included propeller and control surface functions necessary for propulsion and steering. The ability to quickly assemble the vehicle in the field from modular sections allows for rapid deployment without taking up dock space at naval facilities.
The prototype was built in Maryland and transported to California for testing. Testing will continue in 2024, including a low-power, high-efficiency mode underwater. The agency is working with the Navy to determine the next steps for testing and the future implications of the technology.
PacMar Technologies, based in Honolulu, is also testing a similar vehicle as part of a program for a new class of long-range, long-endurance autonomous underwater vehicles. The agency is collaborating with PacMar Technologies to advance the capabilities of these vehicles and evaluate their potential for real-world operations.
The Manta Ray is designed to be a long-endurance, long-range, payload-capable UUV ready for persistent operations in dynamic maritime environments. The agency is focused on developing innovative technologies for the Navy that will enhance their capabilities in underwater operations. The successful testing of the Manta Ray prototype validates its readiness for real-world operations and demonstrates the unique capabilities of an extra-large UUV.
Overall, the development and testing of the Manta Ray prototype represent a significant advancement in underwater drone technology for the US military, with potential applications in various Navy operations. The collaboration between Northrop Grumman, the agency, and PacMar Technologies highlights the importance of partnerships in advancing defense technology for national security.
