What is the rank of an O-1 in the Navy?

In the Navy, the rank of an O-1 is classified as "Ensign." This rank is the entry-level officer position and typically held by newly commissioned officers who have completed their training and are starting their naval careers. An Ensign is responsible for assisting in the management of a division or department, supporting senior officers, and learning the duties and responsibilities of being a naval officer.

Understanding the ranking system is crucial for recognizing the hierarchy and structure within the Navy, as each rank carries specific duties and responsibilities. The other ranks mentioned, such as Lieutenant Junior Grade, Lieutenant, and Captain, represent higher levels within the officer ranks, with Lieutenant Junior Grade being O-2, Lieutenant being O-3, and Captain being O-6. Therefore, knowing that Ensign is the first officer rank provides a foundational understanding of officer progression and the structure of naval command.
