Submarine Engineering Duty insignia
The Submarine Engineering Duty Insignia is a badge of the United States Navy which is issued to Limited Duty Officers who have been commissioned as Engineering officers in the U.S. Navy submarine service. The badge is a variation of the Submarine Warfare insignia and portrays a propeller blade flanked by two dolphins.
The Submarine Engineering Duty Insignia is only authorized to those officers who have been granted commissions through the Navy's LDO (Limited Duty Officer) Program and have been assigned the officer designator as an Engineering Duty Officer. Such officers receive advanced training in nuclear propulsion, submarine construction, and systems management and analysis.
The Submarine Engineering Duty Insignia is only awarded after a service member completes the Submarine Engineering Duty Officer PQS (Personal Qualification Standards) which tests engineering knowledge, submarine operations, and an abbreviated amount of tactical knowledge. Those receiving the Submarine Engineering Duty Insignia are qualified to assume duties leading to that of Chief Engineer onboard a nuclear powered submarine, or as a Port Engineer in a Navy submarine shipyard.
