US Navy Ranks

Note: As of September 29, 2016, the U.S. Navy chose to standardize their rating system to align with how the Army, Marine Corp, and Air Force categorize their servicemember's rankings. As we know, enlisted men and women included in the E-1 to E-3 pay grade were previously referred to by their Navy rate title. Each pay grade was separated into 5 groups: Seaman, Fireman, Airman, Constructionman, and Hospitalman. Today, they removed 4 groups and abolished the rating system. Now, the lowest naval ranks are all defined as a Seaman.

The Navy's enlisted ranks include seaman (E-1 to E-3), non-commissioned officers (NCOs) or Petty Officers (E-4 to E-6), Chief Petty Officers (E-7), Senior Chief Petty Officers (E-8), Master Chief Petty Officers (E-9), and Command Master Chief Petty Officer and Fleet of Force Master Chief Petty Officer (E-9). Enlistees must be between the ages of 17 and 34. For 0 to 4 years service, enlisted sailor's monthly salaries range from $1,566.90 for E-1 to $2,016.40 E-5 pay grades.

Warrant Officers (W-1 to W-5) are qualified senior enlisted personnel who are within the E-7 to E-10 pay grade, have completed at least 12 years service, and are in good moral standing.

"Today, as commissioned officers of the line or staff corps, Navy CWOs possess the authority and are qualified by extensive experience and knowledge to direct the most difficult and exacting operations within a given occupational specialty.  Although intended primarily as technical specialists, CWOs may also serve as division officers, department heads, OICs, X0 and CO, ashore or afloat."
