The General Dynamics Mission Systems Bluefin-9 is a two-man-portable autonomous unmanned underwater vehicle (UUV) providing high-resolution data, navigation, data processing and fast mission turnaround. It features a full carbon fiber body and an integrated sensor suite. Standard payloads include side scan sonar with full swath bathymetry, an HD machine vision camera, sound velocity/temperature/pressure sensors, turbidity and fluorometry.

Developed by Bluefin Robotics (now General Dynamics Mission Systems) in the United States and introduced around 2012, it is a sophisticated platform for deep-sea missions.
