The Nigerian Navy (NN) is the maritime branch of the Nigerian Armed Forces. It is responsible for protecting Nigeria’s territorial waters, combating piracy, securing offshore assets, and supporting national security operations.
Like the Nigerian Army and Nigerian Air Force, the Navy follows a structured rank system. Each rank has a unique insignia that identifies an officer’s authority, responsibility, and position within the service.
This guide explains the complete Nigerian Navy ranks and symbols for 2026/2027.
Nigerian Navy Rank Categories
The Nigerian Navy has two main categories of personnel:

Commissioned officers hold command and leadership positions, while ratings perform operational, technical, and support duties across the service.
