Summary Specs Gallery

The Bluefin-9 is a lightweight, two-man-portable autonomous underwater vehicle with a mission turnaround time of less than 15 minutes. Equipped with a side scan sonar and camera, the Bluefin-9 provides the performance of much larger AUVs in a convenient and rapidly deployable package.

COMPACT – The lightweight Bluefin-9 is easily deployed by two people from an inflatable boat and requires minimal support equipment.

ACCURATE NAVIGATION – Bluefin's navigation software combines information from the IMU and multiple other sensors – including GPS, a DVL, a CT sensor and a compass – to provide high-accuracy navigation with an error of less than 0.3% of distance traveled, yielding high-quality data without a costly INS.

RAPID TURNAROUND – The combination of a free-flooded architecture, a pressure-tolerant battery and removable data storage reduces turnaround time between missions to less than 15 minutes. Easy access to subsystems reduces time on deck for maintenance and accelerates operational tempo. In addition, the Bluefin-9 is easily maintainable in the field due to its swappable, modular subsystems.

EASE OF USE – An intuitive software package enables quick and easy planning and monitoring of missions and rapid post-mission processing and display, and is capable of exporting data to third-party software
