Sonar Technician is abbreviated as?

In Navy ratings, each job specialty has a two-letter abbreviation derived from the words in the rating title. Sonar Technician is abbreviated as ST because the letters come from the two-part title (Sonar and Technician). This shorthand is used on insignia, rosters, and official documents to quickly identify a sailor’s specialty. The other options correspond to different ratings—Yeoman (YN), Musician (MU), and Personnel Specialist (PS)—so they don’t apply to Sonar Technician. The ST abbreviation specifically signals someone who works with sonar equipment and related undersea acoustics.
