Even the Oceans are not Free: Swarming the Seas

The Ocean of Things of Defence Advanced Research Projects Agency (DARPA) aims to  wire up the high seas with swarms of floating, connected sensors.  Such devices are not in themselves new. There are around 6,000 floating sensors deployed around the world’s oceans, run by navies and research institutes. What is unprecedented is the scale of  DARPA’s ambition. Over the next few years it hopes to deploy 50,000 sensors across 1m square kilometres of sea, an area considerably larger than Texas. The eventual goal—much more distant—is to enable the continuous monitoring and analysis of a significant fraction of the world’s oceans.

Existing “floating instrument packages”, known as floats or drifters, are often custom-built, and usually contain the highest-quality instruments available. They therefore tend to be expensive, and are bought only in small numbers. A typical existing float, designed for scientific research, is the Argo. It costs around $20,000, and can measure water temperature and salinity.  The Ocean of Things takes the opposite approach. The aim is to cram as many cheap, off-the-shelf components as possible into a single low-cost package. Current float prototypes cost around $750…That would allow tens of thousands to be deployed without breaking the bank. Large numbers are crucial for coverage. They also help compensate for inaccuracies in individual instruments.

The project’s researchers are evaluating three designs from different manufacturers, ranging in size from about six to 18 litres. One, proposed by Xerox’s Palo Alto Research Centre, is made of glass, like a traditional Japanese fishing float. A second, from a firm called Areté Associates, has an aluminium shell, and uses wood for buoyancy. Both models feature solar panels. The third, made by a company called Numurus, is made of lacquered cardboard, and relies entirely on its batteries. All three are designed to last for a year or so and are made to be as environmentally friendly as possible, with minimal use of plastics. That is important because, at the end of their mission, the floats are designed to scuttle themselves

With 361m square kilometres of ocean on the planet, a true Ocean of Things, monitoring everything on and under the water, would require about 18m floats.

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.

Sea Supremacy with Boat Drones

To protect the natural resources in the EEZ, which stretch 200 nautical miles from a country’s coastline, countries need almost constant presence in the open seas. One option is unmanned surface vehicles (USVs)…

Israel recently discovered huge reservoirs of natural gas in the Mediterranean and these are threatened by the Hezbollah terror organization in Lebanon. This threat accelerated the development of advanced USVs by some Israeli defence companies. Rafael was the first to develop such a system. The company’s Protector USV proved its capability to launch Spike ER missiles.   Protector can carry a variety of weapons and equipment, including a water cannon, electronic warfare systems for protection and escort of naval vessels, mine countermeasures equipment, the Toplite electro-optical long-range detection and tracking system, and Spike missile…. It can also fit the Mini-Typhoon stabilized gun mount…

In Yemen, the Houthis  attacks against navy and commercial ships are performed by Chinese made C-802 missiles and other weapons like anti-tank rockets launched from speed boats. “In such an arena, the Protector with the Spike ER missiles is the best solution for protecting such a vital connection between seas,” the Rafael official said…Intelligence sources say that the Houthis have been building capabilities to perform “Swarm Attacks” using a number of high speed boats.

Elbit systems, another Israeli major defence company has developed the Seagull USV. This is a 12-meter long vessel that can be operated from a mother-ship or from shore stations…And Israel Aerospace Industries (IAI) has also joined the trend and developed the Katana USV …Meteor Aerospace, a new Israeli company developed the Orca. The Orca vessel is a 13 metres long, and weighs eight tons.
