What role does an O-3 hold in the Navy?

In the Navy, an O-3 holds the rank of Lieutenant. This rank follows the rank of Ensign (O-1) and Lieutenant Junior Grade (O-2) in the officer progression. As a Lieutenant, an O-3 is typically responsible for a wide range of leadership and operational duties, which may include leading a division, managing personnel, and overseeing specific projects or tasks across different areas of the Navy. Lieutenant is a pivotal rank that often serves as a bridge for officers transitioning from junior to senior leadership positions.

This rank's responsibilities are critical to the effective functioning of Navy operations and are typically characterized by increased authority and the expectation of more advanced decision-making compared to lower ranks. The role emphasizes both the tactical and administrative responsibilities that Lieutenants must fulfill in their service.
