Bluefin-9 Sealion configuration

Platform: Bluefin-9
Manufacturer: Bluefin Robotics
Commercial Operator: US Navy Unmanned Maritime Systems Program Office


The Bluefin-9 was designed for bottom mapping in shallow water. Its modular design features standalone, pressure-tolerant battery and data modules that can be exchanged for fresh units through a hatch without opening pressure vessels. Bluefin AUVs use gimballed, ducted propulsors. Such propulsors simplify the design by eliminating control surfaces and their actuators and are thought to reduce fouling.
