. However, in the U.S. Navy, only officers carry the term ''rank'', while it is proper to refer to an enlisted sailor's pay grade as ''rate.'' The same term also refers to one's area of occupational specialization within the enlisted Navy. Associated with the enlisted pay grades is a numbering system from the most junior enlisted sailor ("E-1") to the most senior enlisted sailor ("E-9"). This enlisted numbering system is the same across all six branches of the U.S. military. All E-1s through E-3s are known as seaman, fireman, airman, constructionman, or hospitalman. E-4 through E-6 are called petty officers. All E-7s are called chief petty officer, E-8s senior chief petty officer, and E-9s master chief petty officer. Rates are displayed on a rating badge, which is a combination of rate and

. E-2s and E-3s have color-coded group rate marks based on their career field. Personnel in pay grade E-1, since 1996, do not have an insignia to wear. Ratings are earned through "A" schools, which are attended before deployment and after undergoing initial basic training at Recruit Training Command, Great Lakes, Illinois, or (less commonly) by "striking" for a rating through on-the-job training (OJT) in the Fleet. Some sailors may undergo additional training in a "C" school either before or after a tour of duty. Upon completion, they are assigned a four-digit Navy Enlisted Classification (NEC) code, which identifies a specific skill within their standard rating. This defines what jobs they are qualified to do. For example, some billets might not only require a hospital corpsman first class, but might specify that they have NEC 8402 (Submarine Force Independent Duty), NEC 8403 (Fleet Marine Forces Reconnaissance Independent Duty Corpsman), or any other of several NECs depending upon the billet's requirements.

History

On 29 September 2016, the United States Navy discontinued enlisted ratings after 241 years of use in an effort to modernize the classification system. Naval sailors were thereafter to be referred to solely by their rank and would hold a Navy Operations Specialty (NOS) instead of a rating. The

symbols depicted for each rating badge listed below (except for the rating badge of a command master chief) is boatswain's mate. However, the decision was reversed and the rating system was restored in December 2016.

E-1 to E-3

Sailors in pay grades E-1 through E-3 are considered to be in apprenticeships while searching or in training for a career path. They are divided into five definable groups or job communities, with colored group rate marks designating the group to which they belong: seaman, fireman, airman, constructionman, and hospitalman. One of three apprentice devices may be worn above the rank insignia, which denotes the sailor is an apprentice in a particular field and is in search of a rating to join. Sailors who have gone directly to a base, station, or ship without any specialized training are eligible to select a career field, and through correspondence courses and extensive on-the-job training, may qualify for a rating. This process is called "striking for a rating". If a sailor has qualified for a rate, but has not yet become a petty officer, they are called a designated striker, and are identified by a striker's badge that displays the sailor's rating, along with their group rate marks. The service member is addressed by one's group designation, if known (e.g., Fireman Jones, Constructionman Apprentice Smith); by the generic appellation "seaman"; or by one's striker designation (Boatswain's Mate Seaman Watson, Culinary Specialist Seaman Recruit Johnson). Those who have completed the "A" school for

In the September 2016 rating change, it was announced that only the "seaman" group would remain as the rate title for E-1, E-2, and E-3, with the others being retired. However, the Navy reversed this new policy three months later and reinstated the traditional rating system.

Petty officers have been an important part of the U.S. Navy since its beginning. They were originally appointed by the ship's captain and usually held such appointments while serving under the captain who selected them. The petty officers of this time did not have uniforms or a rank insignia. In 1841 a rate badge was assigned, consisting of a sleeve device displaying an eagle perched on an anchor.

marks did not appear until 1866. From 1885 to 1894, the Navy recognized three classes of petty officers who were authorized to wear a "rate" (rank) insignia consisting of chevrons pointing down under a spread eagle and a rating mark. Unlike the current rate badge, the eagle faced right instead of left. The current insignia for petty officers came about in 1894, and is a perched eagle with spread wings (usually referred to as a "crow," due to its black color on white uniforms and the former light blue working uniforms) above a rating mark, with chevrons denoting their rate below. Initially, the eagle faced left or right on the rating emblem depending on which sleeve the badge was worn. "Seafarer" rates, such as boatswain or gunner, are unique to service aboard a ship, and were worn on the right sleeve; the eagle on these insignia faced right, so that they would be facing forward on the wearer. Other rates, such as administration or medical positions, were worn on the left sleeve, so the eagle on those insignia faced left, so that they would be facing forward on the wearer. In 1948, the Navy standardized all ratings to be worn on the left sleeve. The authority to wear gold rating badges and

or courts martial. During that time, the gold rating badges and service stripes were treated distinctly from the Good Conduct Medal, which was and is awarded for three consecutive years of "honorable service", defined as being free of disciplinary infractions. Coloration of the insignia for E-4 through E-9 depends upon the uniform worn. Black cloth with red or gold embroidered stripes is used on the winter uniforms, while white cloth with black embroidered stripes is used on the summer uniforms, and medium blue cloth with red or gold embroidered stripes is used on the working coverall, depending on whether or not they have less or more than 12 years of service respectively.

The rates senior chief petty officer and

were established on 1 June 1958. To be eligible for advancement to senior chief petty officer, a chief petty officer must have had three years in the current grade. For advancement to master chief, a senior chief must have a total of three years in the current grade. The dress blue insignia consists of a perched eagle (or "crow") with spread wings atop a rating mark, with three chevrons and one 'rocker' above the rating mark. Inverted five-point stars above the crow denote the rank of senior chief (one star) or master chief (two stars). All other uniforms use the collar device to denote rank. It consists of a fouled anchor (an anchor that is entangled with its chain) with the initials U S N in silver, superimposed, with stars above the anchor to indicate higher pay grades, similar to the dress blue insignia.

Command senior chief

On 30 July 2015, the Navy formally established the rating of command senior chief (CMDCS); before then from 2005 to 2015 it had been a billet instead of a rating.

, a sailor may choose to further their career by becoming a command master chief petty officer. Both command senior chief and command master chief existed as a position before being authorized as separate rates/rank. For example, there could be a senior chief boatswain's mate acting as command senior chief or a master chief personnelman who acts as the command master chief. The command master chief rate insignia are similar to the insignia for master chief, except that the rating symbol is replaced by an inverted five-point star, reflecting a change in their rating from their previous rating (e.g. MMCM) to CMDCM. The stars for command master chief are silver, while stars for fleet or force master chief are gold. Additionally, command master chiefs, wear a badge, worn on their left breast pocket (for males) or above the nametag (for females), denoting their title (Command/Fleet/Force).

Fleet master chief and force master chief

Fleet and force master chiefs are appointed by the commander of a fleet or a force command, to serve as their senior enlisted adviser. They have virtually the same responsibilities as command master chiefs, but for larger fleet or force commands rather than a single unit. These two ranks are equivalent and their insignia is also the same—a master chief rating badge with two gold stars above the eagle and a gold star for the rating insignia.
