The Nigerian Navy (NN) is a branch of the Nigerian Armed Forces. The Nigerian Navy is among the largest Navies on the African continent, consisting of several thousand personnel, including those of the Coast Guard.The Nigerian Navy owes its origin to the Nigerian Marine. Formed in 1914 after the amalgamation of the then Northern and Southern Nigeria, the Nigerian Marine (as it became known after 1914) was a quasi-military organization. This force expanded to become the Southern Nigerian Marine in 1893. A Northern Nigeria equivalent was formed in 1900. The two Marines were merged in 1914. The responsibilities of the Marine included administration of the ports and harbours, dredging of channels, buoyage, and lighting. It also operated ferry services, touring launches, and other small craft that plied the various creeks and other inland waterways.
