Bluebottles are being used in ‘Operation Resolute,’ announced the Australian Defense Force.

‘Operate Resolute’ refers to the Defense Force’s actions to protect the borders via surveillance and response. Australia is known for its tough stance on illegal migration and even turning away migrant boats.

What is the new technology?

In the age of drones, unmanned surface vessels are being tested and used on the seas. Bluebottle refers to a specific USV developed by the Australian company Ocius.

How does the Bluebottle work?

According to Ocius, the Bluebottle can be launched from a boat ramp or a ship.

It can then move or stay at sea for months. The hard solar sail makes it possible by harnessing solar and wind energy. When not in use, it folds into the deck of the Bluebottle.

As to the rudder flipper, it steers, guides, and powers the unmanned vessel, generating forward thrust from the vessel’s pitching in the waves.

It can power large payloads and autonomously monitor the target areas for an extended period.

Multiple sensors are located inside the hull and on the aft comms mast. Live tracking is possible via an integrated and networked communication system.

It has a 5-knot hull speed and can advance in all conditions by getting out of currents.
