Libyan Navy is the branch of the Libyan military responsible for naval warfare. Established in November 1962, Libyan Navy has been headed by Admiral Mansour Bader, Chief of Staff of the Libyan Naval Force. Before the Libyan Civil War it was a fairly typical small navy with a few missile frigates, corvettes and patrol boats to defend the coastline, but with a very limited self-defence capability. The Navy has always been the smallest of Libya's services and has always been dependent on foreign sources for equipment, spare parts, and training. Most of the Gaddafi era fleet was destroyed in 2011. Since the start of the ongoing internal conflict, the Libyan Navy is aligned with the Government of National Accord (GNA), led by the Presidential Council in Tripoli, apart from coastal patrol vessels under the control of the Libyan National Army.
