Qualified submariners wear the traditional insignia: A bow view of a submarine proceeding on the surface with  bow planes rigged for diving, flanked by two dolphins (traditional attendants to Poseidon, the patron deity of  sailors) resting their heads on the bow planes.

     "Earning Dolphins" is one of the most significant events in a Navy submariner's career - one of those special high points that instills great personal pride and recognizes a tremendous accomplishment.

     Dolphins are earned through a process of "Qualifying ". Individuals must learn the location of all major equipment,  operation of all systems, damage control procedures and have a solid understanding of operational characteristics of their boat. Dolphin wearers qualify initially on one boat and must requalify on boats to which they are subsequently assigned.  Once Dolphins have been earned, they are awarded by the Commanding Officer in a special ceremony.
