Nigerian Navy Overview
The Nigerian Navy’s formal beginnings can be traced to 1887 when a Marine Department was established. After Nigeria’s independence, this department became an independent naval force.
Today, it serves a vital function in the region of the Gulf of Guinea along one of the world’s most important, busiest shipping routes.
The Nigerian Navy is a constituent part of the Nigerian Armed Forces, and the Chief of the Naval Staff (CNS) is its head.
Its key responsibilities are:
- Defending Nigeria’s territorial waters
- Protecting offshore oil and gas infrastructure
- Combating piracy and sea robbery
- Maritime law enforcement
- Anti-smuggling operations
- Search and rescue missions
- Humanitarian assistance and disaster relief
- Supporting joint military operations
