This guide provides a detailed look at the many ratings (occupational specialties) held by enlisted personnel in the U.S. Navy from World War II through the early 21st century. From deck seamen to electronics technicians, aviation specialists, and medical corpsmen, these roles defined sailors' skills, duties, and career progression.

 

📌 What Is a Navy Rating?

A rating is the Navy's term for a job specialty or occupational field. Enlisted sailors receive both a rate (pay grade) and a rating (job title). For example, a Boatswain's Mate First Class is abbreviated BM1 — with BM as the rating and 1 as the pay grade (E‑6).
