Overview
Solar-, wind-, and wave-powered Australian persistent USV for long-duration maritime surveillance, ocean sensing, communications relay, defense, and scientific missions.
Bluebottle USV is a dual-use Australian uncrewed surface vessel developed by Ocius. The platform harvests solar, wind, and wave energy through a fold-down solar sail and rudder-flipper concept, enabling persistent maritime surveillance and ocean data collection without fuel or crew. Ocius positions Bluebottle for defense, oil and gas, and science missions, including maritime domain awareness, anti-submarine warfare support, electronic warfare support, mine countermeasures support, gateway communications, ocean monitoring, and hydrographic or environmental sensing. Published figures captured here include a 5 kt hull speed, 300 kg modular payload, 100-120 W average payload power, and human-on-the-loop autonomous operations. Earlier Ocius material describes the platform as about 5.8 m long, while current product material emphasizes modular Bluebottle classes and persistent months-at-sea operation.
Primary Roles
Notes
Ocius lists Bluebottle USVs as renewable-energy powered vessels using solar, wind, and wave energy, with 5 kt hull speed, 300 kg modular payload, 100-120 W average payload power, team behaviors, and human-on-the-loop control. Ocius also states Bluebottles can remain at sea for months at a time and that Australian Defence is acquiring a fleet for undersea warfare and maritime surveillance capability.
