Seaman Apprentice is the second lowest enlisted rank in the U.S. Navy, just above Seaman Recruit and below Seaman; this rank was formerly known as Seaman Second Class. If applicable, the occupational titles of Airman Apprentice or Fireman Apprentice (and formerly, Constructionman Apprentice) are used in place of Seaman Apprentice, but the rank remains the same. Advancement to Seaman Apprentice is attained after a certain number of weeks in service, which roughly corresponds to the duration of basic training. This policy results in all sailors graduating as Seaman Apprentice or higher.
