The Integrated Undersea Surveillance System Badge is a military badge of the United States Navy which has been existence since the 1970s. The badge is awarded to those personnel who have been trained and qualified in naval sonar and undersea surveillance technology.
A direct result of the Cold War, the Integrated Undersea Surveillance System Badge was originally created due to the rise in Soviet submarine technology during the 1960s and 1970s. With the fall of the Soviet Union, the Integrated Undersea Surveillance System Badge became a symbol of the “brown water” submarine threats of such nations as North Korea and China.
To be awarded the Integrated Undersea Surveillance System Badge, a service member must have completed initial sonar technology training followed by 18-24 months of field experience in naval undersea surveillance. The Integrated Undersea Surveillance System Badge is only presented following completion of prescribed personal qualification standards (PQS), as well as a successful completion of a written and oral examination board.
The badge, itself, consists of a seahorse superimposed on a winged globe. The badge is issued in two degrees: silver for enlisted personnel and gold for officers. The Integrated Undersea Surveillance System Badge is one of the rarest badges of the Navy as it is only presented to enlisted sailors who hold sonar ratings and to limited duty and restricted line officers trained in sonar operations.
