Black Operations are Getting Blacker: US Military

Heterogeneous Collaborative Unmanned Systems (HCUS), as these drones will be known, would be dropped off by either a manned submarine or one of the navy’s big new Orca robot submersibles.

They could be delivered individually, but will more often be part of a collective system called an encapsulated payload. Such a system will then release small underwater vehicles able to identify ships and submarines by their acoustic signatures, and also aerial drones similar to the BlackWing reconnaissance drones already flown from certain naval vessels.

Once the initial intelligence these drones collect has been analysed, a payload’s operators will be in a position to relay further orders. They could, for example, send aerial drones ashore to drop off solar-powered ground sensors at specified points. These sensors, typically disguised as rocks, will send back the data they collect via drones of the sort that dropped them off. Some will have cameras or microphones, others seismometers which detect the vibrations of ground vehicles, while others still intercept radio traffic or Wi-Fi.

HCUS will also be capable of what are described as “limited offensive effects”. Small drones like BlackWing can be fitted with warheads powerful enough to destroy an SUV or a pickup truck. Such drones are already used to assassinate the leaders of enemy forces. They might be deployed against fuel and ammunition stores, too.

Unmanned systems such as HCUS thus promise greatly to expand the scope of submarine-based spying and special operations. Drones are cheap, expendable and can be deployed with no risk of loss of personnel. They are also “deniable”. Even when a spy drone is captured it is hard to prove where it came from. Teams of robot spies and saboteurs launched from submarines, both manned and unmanned, could thus become an important feature of the black-ops of 21st-century warfare.

Undersea Drones: Military

Currently, manipulation operations on the seabed are conducted by Remotely Operated Vehicles (ROVs) tethered to a manned surface platform and tele-operated by a human pilot. Exclusive use of ROVs, tethered to manned ships and their operators, severely limits the potential utility of robots in the marine domain, due to the limitations of ROV tether length and the impracticality of wireless communications at the bandwidths necessary to tele-operate an underwater vehicle at such distances and depths. To address these limitations, the Angler program will develop and demonstrate an underwater robotic system capable of physically manipulating objects on the sea floor for long-duration missions in restricted environments, while deprived of both GPS and human intervention

The Angler program seeks to migrate advancements from terrestrial and space-based robotics, terrestrial autonomous manipulation, and underwater sensing technologies into the realm of undersea manipulation, with specific focus on long-distance, seabed-based missions. Specifically, the program aims to discover innovative autonomous robotic solutions capable of navigating unstructured ocean depths, surveying expansive underwater regions, and physically manipulating manmade objects of interest.
