The Nigerian Navy is one of the three arms of the Nigerian Armed Forces. Like all military institutions, it operates under a strict hierarchy of ranks. These ranks define responsibilities, authority, and privileges within the Navy. The structure is similar to other navies around the world and is divided into two main categories:
1. Commissioned Officers
These are trained leaders responsible for planning operations, managing personnel, and commanding naval units.
Officer Ranks (from highest to lowest):
-
Admiral of the Fleet (Ceremonial – rarely used)

Midshipman – Entry-level officer rank for cadets undergoing training.
2. Non-Commissioned Officers (NCOs) & Ratings
These personnel handle the technical and operational tasks on ships, submarines, and shore facilities.
Ratings and NCO Ranks (from highest to lowest):
-
Warrant Chief Petty Officer (WCPO)
