Last updated: 08 Sep 2021

Description
The U.S. Navy’s Supervisor of Salvage and Diving (SUPSALV) Trondheim (a Kongsberg Hugin AUV) is an autonomous underwater vehicle capable of long duration, highly accurate, autonomous underwater searches to a depth of 6,000 meters (20,000 FSW).

The system consists of the autonomous vehicle, a launch sled, and an operations and maintenance van.  SUPSALV’s newest AUV is capable of sonar searches, multi-beam mapping, sub-bottom profiling, magnetic sensing, and high resolution still camera observation.

Features
The vehicle can operate in three modes: autonomous, supervised and trajectory mode. The autonomous mode has no operator input and the vehicle follows a preplanned route with up to 50-hours of run time.  In supervised mode, the operator receives real-time payload data for quality management purposes. 

The Hugin AUV is equipped with acoustic communication links providing real time status monitoring of the vehicle, its position, and payload sensor functioning. The acoustic links also add the capability to receive payload data from the vehicle in real time as a quality measure, ensuring an effective survey.   

SUPSALV’s Trondheim’s payload, the Synthetic Aperture Sonar is equipped with HiSAS 2030 technology High Resolution Interferometric Synthetic Aperture Sonar with a resolution of 4cm x 4cm and a 300 – 600 m swath for a daily coverage of 4–10 nautical miles squared. The system is air transportable and can operate from any capable platform of opportunity.
