The history of the U.S. Navy Chief Petty Officer (CPO) is a story of leadership, tradition, and evolution within the Navy’s structure. Below is an overview of its key milestones:

Establishment of the Rank

• The rank of Chief Petty Officer was officially established on April 1, 1893, marking a pivotal moment in the Navy’s history. This date is celebrated annually as the “Navy Chief’s birthday.”
• The creation of the rank addressed a leadership gap between officers and enlisted sailors, providing a senior enlisted rank to bridge this divide and enhance career advancement opportunities for enlisted personnel.
• Initially, the rank included nine specialties, such as boatswain’s mate, gunner’s mate, and machinist. Over time, it expanded to encompass other roles like electrician and radioman.

Role and Responsibilities

• CPOs were tasked with providing leadership, training junior sailors, and ensuring discipline and operational readiness aboard ships. They became known as the “backbone” of the Navy.
• Chiefs are expected to be technical experts in their fields and uphold Navy traditions while mentoring both junior and senior personnel.

Evolution of the Rank

• In 1958, two additional pay grades were introduced: Senior Chief Petty Officer (E-8) and Master Chief Petty Officer (E-9), further formalizing the enlisted leadership structure.
• The first Master Chief Petty Officer of the Navy (MCPON), Delbert D. Black, was appointed in 1967, serving as a senior enlisted advisor to Navy leadership.

Historical Contributions

• During World Wars I and II, CPOs played critical roles in training recruits, maintaining equipment, and leading combat operations. They were instrumental in submarine campaigns and major invasions like Normandy.
• Roberta L. Hazard became the first female Chief Petty Officer in 1972, breaking barriers for women in the Navy.

Traditions and Legacy

• CPOs are considered “caretakers” of Navy history and traditions. Over the decades, Chiefs have been entrusted with preserving Navy heritage and instilling the core values—Honor, Courage, and Commitment—in generations of Sailors, shaping today’s Navy.
• The Career Compensation Act of 1949 standardized pay for all CPOs and eliminated distinctions between temporary (“acting”) and permanent appointments by 1965.

The rank of Chief Petty Officer remains a cornerstone of U.S. Navy leadership, symbolizing professionalism, expertise, and dedication to service.

The history of the U.S. Submarine Warfare Insignia, commonly known as “Dolphins,” dates back to 1923 when Captain Ernest J. King, then Commander of Submarine Division Three, proposed creating a distinctive badge for qualified submariners. He submitted a pen-and-ink sketch depicting a shield mounted on the beam ends of a submarine, flanked by dolphins forward and abaft the conning tower. The idea was strongly endorsed by the Commander of Submarine Division Atlantic and forwarded to the Bureau of Navigation (now Naval Personnel Command) for further development.

On March 20, 1924, the Chief of the Bureau of Navigation recommended adopting this design, which was approved by Theodore Roosevelt Jr., Acting Secretary of the Navy. Initially, the insignia was worn only while attached to submarine units or commands but later became a permanent badge for qualified submariners in 1941.

“Dolphins” symbolize the identity and prestige of submariners and are considered one of the Navy’s oldest and most challenging warfare badges to earn.

Qualification in submarines is a daunting task. However, once finished you become part of a fellowship that can only be understood by those who have done it themselves. That can only be truly recognized by the very small and special group of men that have the pride and honor of calling themselves SUBMARINERS.
