The program is run by the Defense Advanced Research Projects Agency, or better known as DARPA’s Manta Ray drone. This project involves prototypes developed by Northrop Grumman and PacMar Technologies, with Northrop’s model undergoing testing earlier this year off the southern California coast.
Chinese development of similar underwater drones
A report from China Central Television (CCTV) reveals that China has developed six variants of soft-bodied submersible drones that “mimic the manta ray.” These drones have been deployed in the South China Sea and larger versions are being developed for armed reconnaissance missions.
The prototype drones have been developed by a team from Northwestern Polytechnic University in China, and are equipped with cameras, probes and the BeiDou satellite navigation system. In the past year, they have conducted underwater operations for 60 days, and researchers are preparing for deep-water testing with an 800-kilogram version. In addition, they have a capacity that will allow them to carry heavier loads and navigate longer distances.
A Beijing military expert told the Global Times that these new drones, by mimicking the swimming of manta rays, possess greater endurance, range and acoustic stealth compared to conventional submarines. These characteristics could be critical in anti-submarine and anti-ship operations.
DARPA’s Manta Raya project
On the other hand, DARPA was pleased with the testing of Northrop’s Manta Ray prototype in the past quarter, which included submerged operations using all propulsion and steering modes of the vehicle. A key part of the test was conducted on land, where the Manta Ray underwater drone was shipped from Maryland to California and quickly assembled.

DARPA program manager, Dr. Kyle Woerner, noted that the successful test validates the vehicle’s readiness for real-world operations, combining modular transport, field assembly and subsequent deployment, which shows a unique capability for an extra-large unmanned underwater vehicle (UUV).
Currently, DARPA and the U.S. Navy are evaluating the next steps in the development of the Manta Ray. The Navy has been working on underwater drone programs for some time, and the AUKUS alliance (Australia, United Kingdom and United States) has also developed UUVs, including those that can be launched from submarine torpedo tubes, intended for reconnaissance missions and other activities.
