The Bluebottle uncrewed surface vessel (USV) is a groundbreaking Australian designed USV powered by solar, wind and wave energy enabling long-endurance operations while maintaining an acoustically quiet environment for superior acoustic surveillance.
Built for continuous operations, Bluebottles have been operated and validated in sustained real‑world missions - not just trials

The Bluebottle Hybrid supplements renewable energy sources of the Bluebottle USV with a diesel generator.
This provides additional power for operations in low-light conditions such as during high latitude winters and delivers persistent uptime for high-power payloads.
Keeping logistics simple, the Bluebottle Hybrid uses the same hull, trailer and launch method as the renewable energy powered Bluebottle.

The bluebottle is a marine organism (also known as a Portugese Man of War in some parts of the world) often known for its sting. But, it is also an extraordinary pleustonic drifter, living right at the air-sea interface and interacting with wind, waves and surface conditions in ways scientists are still trying to better understand.
That kind of natural design is a beautiful reminder that marine life does not only matter ecologically, it can also shape how we think, build and innovate.
