The mission of the Pakistan Navy is to protect the maritime interests of Pakistan, and to deter aggression at and from sea.
The Pakistan Navy is the naval warfare branch of the Pakistan Armed Forces, responsible for Pakistan's 1,046 kilometers (650 mi) coastlines along the Arabian Sea and the defence of important civilian harbours and military bases. The Pakistan Navy is also focused on limited global expeditionary operations, and played a vital role in the establishment of Pakistan Antarctic Programme.
The Pakistan Navy is currently undergoing extensive modernization and expansion as part of Pakistan's role in the War on Terror. Since 2001, the Pakistan Navy has increased and expanded its operational scope and has been given greater national and international responsibility in countering the threat of sea-based global terrorism, drug smuggling and trafficking issues.
