The Algerian National Navy is the naval branch of the Military of Algeria. The navy operates from multiple bases along the country's nearly 1,000 km (620 mi) coastline, fulfilling its primary role of monitoring and defending Algeria's territorial waters against all foreign military or economic intrusion. Additional missions include coast guard and maritime safety missions as well a projection of marine forces (fusillers marins). Algerian forces are an important player in the Western Mediterranean.
As with other Algerian military branches, the navy was built and structured with assistance from the Soviet Union during the Cold War, but has also relied on other sources for equipment in some areas. Since the end of the Cold War, Russia has remained an important partner, but Algeria has increasingly sought additional sources for equipment as well as building its own shipbuilding capacity.
