What is an O-4 in the Navy?

• A. Lieutenant
• B. Commander
• C. Lieutenant Commander
• D. Captain

Answer: (C)

In the Navy, commissioned officers are organized by pay grades from O-1 to O-10, with each step up generally meaning more experience and responsibility. An O-4 is the rank of Lieutenant Commander, which sits between Lieutenant (O-3) and Commander (O-5). In practice, a Lieutenant Commander often serves as a department head on a ship or as a senior staff officer, handling both leadership and operational tasks. The other ranks listed correspond to different pay grades: Lieutenant is one step below O-4, while Commander and Captain are higher ranks.
