Bluefin21

Bluefin21 is an autonomous underwater vehicle (AUV) developed by Bluefin Robotics. It is designed for a variety of underwater missions, including mine countermeasures, hydrographic surveys, and reconnaissance. The Bluefin21 is a versatile platform capable of operating at depths down to 4,500 meters, making it suitable for deep-sea exploration and operations.

The AUV is characterized by its modular design, which allows for the integration of different sensor payloads depending on the mission requirements. These sensors can include sonar systems for imaging the seabed, cameras for visual inspection, and environmental sensors for collecting data on water properties. Its navigation system typically utilizes inertial navigation and GPS when at the surface, with acoustic positioning systems used for precise localization during submerged operations.

Bluefin21 is powered by batteries and can operate for extended periods, with mission durations varying based on speed and operational depth. Its deployment and recovery are typically managed from a surface vessel. The data collected by the Bluefin21 is processed to create detailed maps and gather information about the underwater environment. The vehicle has been used in various scientific and military applications globally.
