The Submarine Warfare Insignia (usually known as '"Dolphins"') are worn by qualified submariners.

United States Navy Officers and Enlisted Sailors wear a uniform breast pin to indicate that they are qualified in submarines.

The Submarine Warfare Insignia is considered one of the Navy's three major enlisted warfare pins, along with the Surface Warfare Badge and the Enlisted Aviation Warfare Specialist insignia. To earn the right to wear "dolphins", 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 all of the submarine's systems.

History On 13 June 1923, Captain Ernest J. King, Commander, Submarine Division Three (later Fleet Admiral and Chief of Naval Operations during World War II), suggested to the Secretary of the Navy (Bureau of Navigation) that a distinguishing device for qualified submariners be adopted. He submitted a pen-and-ink sketch of his own showing a shield mounted on the beam ends of a submarine, with dolphins forward of, and abaft, the conning tower. The suggestion was strongly endorsed by Commander Submarine Division Atlantic.

Over the next several months the Bureau of Navigation (now known as BUPERS) solicited additional designs from several sources. Some combined a submarine with a shark motif. Others showed submarines and dolphins, and still others used a shield design. A Philadelphia firm, which had done work for the Navy in the field of United States Naval Academy class rings, was approached by the Bureau of Navigation with the request that it design a suitable badge.

Two designs were submitted by the firm, but these were ultimately combined into a single design. It was a bow view of a submarine, proceeding on the surface, with bow planes rigged for diving, flanked by dolphins (in the form of artistically stylized heraldic dolphins), in a horizontal position with their heads resting on the upper edge of the bow planes.

Today a similar design is used: two Mahi-mahi, commonly known as dolphin fish, flanking the bow and conning tower of a submarine. On 20 March 1924, the Chief of the Bureau of Navigation recommended to the Secretary of the Navy that the design be adopted. The recommendation was accepted by Theodore Roosevelt Jr., Acting Secretary of the Navy.

Originally, the submarine insignia was to be worn by officers and men qualified in submarine duty only when attached to submarine units or submarine command organizations. The right to wear the pin was revoked if the service member transferred to a non-submarine billet. In 1941 the Uniform Regulations were modified to permit a service member to wear the submarine insignia for the duration of their career, once so authorized.

Appearance The officers' insignia was at first a bronze, gold-plated metal pin, worn centered above the left breast pocket and above the ribbons and medals. Enlisted men wore an embroidered insignia sewn on the outside of the right sleeve, midway between the wrist and elbow. The device was two and three-quarters inches long, embroidered in white silk for blue clothing and vice versa. In 1943, the Uniform Regulations were modified to provide that

"Enlisted men, who are qualified and subsequently promoted to commissioned or warrant ranks, may wear enlisted submarine insignia on the left breast until they qualify as submarine officers, at which time this insignia would be replaced by the officers' submarine pin."

In mid-1947, the embroidered device shifted from the sleeve of the enlisted men's jumper to above the left breast pocket. A change to the Uniform Regulations dated 21 September 1950 authorized the embroidered insignia for officers (in addition to the pin-on insignia) and a bronze, silver-plated, pin-on insignia for enlisted men (in addition to the embroidered device).

Over the years a number of minor design variations, particularly in the appearance of the bow waves, have occurred. Various unofficial or commemorative badges based on the device have also been made, and may have occasionally been worn with the tacit approval of local naval authorities. The 1971 diesel boats forever pin would be an example of this type. Worldwide Submarine Insignia: United States

In the modern Navy, the submarine pin is either a silver or gold chest pin, worn above all ribbons unless a second superseding qualification has been achieved in which case the submarine pin is worn below ribbons on the breast pocket. An embroidered patch, rather than the pin, is worn above the left breast pocket of working uniforms.

Basic enlisted submarine qualifications

Upon reporting to their first submarine the unqualified submarine sailor completes a few days of education and is then assigned a Qualification Card, a qualification due date, and a command sponsor (informally known as Sea Dad or Sea Mom). The assigned sponsor monitors the non-qual's (qualifier's) progress during the qualification process and their adaptation to life aboard the boat. No one is exempted from the qualification process and no concessions are made to rank or rate.

Although submarine qualification methodology has changed throughout the decades, the basic goal has remained: 1) to provide the submarine sailor with a basic knowledge of all systems on board, their uses, operations, and interrelationships with other systems and 2) to ensure all personnel can operate effectively under pressure in shipboard situations. Submarine damage control techniques are stressed throughout the qualification process.

Progress is tracked by a Petty Officer First Class deemed as the Ship's Qualification Coordinator. Each item on the qualification card is worth a specified number of points; unqualified sailors must obtain a predetermined number of points per week. Failure to achieve the required number results in placement on a "delinquent list" (Dinq or Dink) and the assignment of additional study, monitored by their sponsor. Repeated failure to obtain required points might result in the Sailor being restricted to the Boat until he/she is caught up. Each system signature is weighted and each phase has a maximum number of points.

The qualifications process aboard the boat uses publications, training videos, computer programs and hands-on training with qualified personnel, but the principal focus is on the actual operation of the damage control, atmosphere control, weapons, countermeasures, reactor, mechanical, hydraulic, pneumatic, electrical, and electronic systems on that particular submarine. Once the qualifying sailor feels they have the requisite knowledge for the system, they will ask a designated Qualification Petty Officer (QPO — an expert on the system in question) for a "checkout". The QPO will ask prepared questions concerning the system. They can also ask the sailor to draw a line diagram and explain the system in various states and configurations. If the QPO feels the sailor has met their expectations, they will sign the sailor's card and those points will be included in the sailor's weekly point count. If the QPO is not satisfied with the sailor's knowledge level, they will be dismissed to study further and return once the required knowledge threshold has been met.

The qualification structure can be broken down into phases. The example listed below is only a basic guide and is not the rule for all submarines. For most phases of qualification, knowledge of basic rather than elaborate equipment operations is required, with the exception of damage control equipment and procedures. Among the most important goals of submarine qualification is providing each member of the crew, regardless of designated specialty or task, with the training to combat emergencies anywhere on the submarine. In case of fire, flooding, or other casualty, each submarine sailor must be confident that they can trust the sailor next to them to know the purpose, location, and proper use of each item of damage control equipment, as well as the location and operation of isolations for each electrical/air/hydraulic system.

Block Reviews and Walkthroughs Each phase (or "block") of the qualification card has an overall "block review" where the qualifier ties in all the phase's systems and is verbally tested for their level of knowledge.

After completion of all blocks, the qualifier must complete compartment walkthroughs, where a senior, qualified sailor quizzes the qualifier as they walk through the submarine. If all walkthroughs are completed successfully, the qualifier's chain of command recommends that they be examined by a qualification board.

The "Qual Board" This is the most challenging part of the new qualifier's qualification process. The board is made up of a submarine-qualified officer, a chief petty officer and a petty officer. Submarine damage control is the biggest factor discussed during the board.

During the board, the examinee may be asked to draw and explain any of the systems they have learned about during the qualification process. After the board the examinee is dismissed and evaluated by the members of the board. If the examinee passes the board, they are then recommended for qualification to the commanding officer of the submarine.

Some boats have implemented an idea requiring the qualifier to perform on their feet, called a "Snapshot Board". Qualified personnel set simulations for the qualifier to treat as a real casualty. They have to make initial emergency report then lead the fight against the casualty. This type of board was formed to assure the qualifier has practical knowledge, not just "book smarts".

The commanding officer reviews the board's recommendation, and, upon concurrence, the newly qualified individual is presented their "Dolphins" by the skipper and designated as "Qualified in Submarines". The Dolphins presentation is considered an important event as it means the newly qualified submariner will be treated as a full member of the submarine crew. Although not condoned by senior supervisory personnel, the tradition of "tacking on" the decoration, whereby other qualified sailors punch the dolphin badge while worn on the newly qualified sailors breast is a time-honored tradition, done in much the same way as "tacking on" the decoration of newly promoted 3rd Class Petty Officers has been tolerated. With the introduction of Women on Submarines however, this time-honored tradition most likely will no longer be tolerated by the Command.

Appropriate annotations are made in the new submariner's service jacket to reflect qualification. Submarine qualified personnel are designated "SS" after the rate, such as STS1(SS) or MMN2(SS). The "SS" stands for submarine specialist.(OPNAVINST 1414.9)
