The navy (marine), also known as the Armée de mer, is of small size and is commanded by a Ship-of-the-Line Captain. It is responsible for securing Senegal's Atlantic coastline which is strategically located on the extreme west of the African continent. The navy was created in 1961.
The Navy is divided into three branches known as «groupings»:
- The Operational Naval Grouping (Groupement Naval Opérationnel), which is divided into three flotillas and one group
- The Naval Support Grouping (Groupement de Soutien de la Marine) responsible for ports, repairs, training, and logistics
- The Fluvial-Maritime Surveillance Grouping.
