Submarine Warfare Insignia

The Submarine Warfare Insignia (usually known as "dolphins" or "fish") is a uniform breast pin worn by enlisted men and officers of the United States Navy to indicate that they are qualified in submarines. The Submarine Warfare Insignia is considered one of the Navy's three major warfare pins along with the Surface Warfare Badge and the Naval Aviator Badge. To earn the right to wear the pin, prospective submariners complete an extensive qualification process that lasts about one year (for both enlisted and officers, though the two programs differ significantly) and covers virtually all of the submarine's systems.
