The Pakistan Navy (PN) (Urdu: پاک بحریہ, romanized: Pāk Bahrí'a, pronounced [ˈpaːk baɦɽia]) is the naval warfare branch of the Pakistan Armed Forces. The Chief of the Naval Staff, a four-star admiral, commands the navy. The Pakistan Navy operates on the coastline of Pakistan in the Arabian Sea and Gulf of Oman. It was established in August 1947, following the independence of Pakistan.
The primary role of the Pakistan Navy is to defend Pakistan's sea frontiers from any external enemy attack. In addition to its war services, the Navy has mobilized its war assets to conduct humanitarian rescue operations at home as well as participating in multinational task forces mandated by the United Nations to prevent seaborne terrorism and piracy off the coasts.
