Happy Birthday, Dolphins

One of the toughest badges to earn, the Submarine Warfare Insignia, aka the “dolphins” or “fish,” is also one of the Navy’s oldest warfare devices, having been adopted 100 years ago this week.

As detailed by the NHHC:

In the summer of 1923, while serving as Commander, Submarine Division Three, Captain Ernest J. King [Yes, the future WWII CNO] proposed that the Navy create a warfare insignia device for qualified submariners. The insignia came to be known as “dolphins” or “fish,” and is one of the Navy’s oldest warfare devices. The hard-earned badge distinguishes and identifies the members of the submarine community and has since become a source of pride for the “silent service.”

Not only did King propose the idea for the submarine warfare device, he also submitted the initial design. His drawing, which he submitted to the Bureau of Navigation for consideration, included a shield mounted on the beam ends of a submarine, with dolphins forward and aft of the conning tower. The bureau considered a shark and shield motif as well but ultimately hired a Philadelphia jewelry design firm to create the design.

The final design of the device was approved for wear on 24 March 1924. It displays a bow view of a surfaced O-class submarine with two dolphins resting their heads on the submarine’s bow planes. The dolphins depicted on the insignia are actually dolphinfish, or mahi-mahi, not the marine mammal.

One of the earliest designs of the submarine warfare insignia, circa 1924. Enlisted personnel wore this insignia, embroidered in silk, with white silk for blue clothing and blue silk for white clothing, on their right sleeve, midway between the wrist and elbow, a practice that continued until 1950 when the enlisted device became the current silver-plated metal version of the pin.

Dolphins, Dolphins, Dolphins– NATO edition

On 13 June 1923, CPT (later Fleet Admiral) Ernest J. King, at the time Commander, Submarine Division Three, proposed to the Secretary of the Navy that a distinguishing device for qualified U.S. submariners be adopted.

That initiative led to today’s Submarine Warfare Insignia–best known as “dolphins” or “fish.”

Of course, most other fleets that field submarines also have similar badges, though not always accompanied by marine life.

Here are the NATO ones:

Royal Canadian Navy

French Navy

Deutsche Marine (German Navy)

Hellenic (Greek) Navy

Italian Navy

Netherlands

Norwegian

Polish

Portuguese

Turkish Navy

Royal Spanish Navy

Meanwhile, the Swedish Första ubåtsflottiljen wears a submarine insignia pin featuring sharks, which gives you an idea of how Stockholm views their small yet honed undersea arm.
