Pakistan Navy

The Pakistan Navy (Urdu: پاکستان بحریہ‎; Pɑkistan Bahri'a) (reporting name: PN) is the naval warfare branch of Pakistan Armed Forces, responsible for Pakistan's 1,046 kilometres (650 mi) of coastline along the Arabian Sea, and the defence of important civilian harbours and military bases. The Pakistan Navy came into the existence after the independence of Pakistan in 1947, and is headed by Admiral Muhammed Zakaullah. Navy Day is celebrated on 8 September in commemoration of the Indo-Pakistani War of 1965.

The Pakistan Navy's current and primary role is to protect the country's economic and military interests at home and abroad, executing the foreign and defence policies of the Government of Pakistan through the exercise of military effect, diplomatic activities and other activities in support of these objectives. In the 21st century, the Pakistan Navy also focuses on limited overseas operations, and has played a vital role in the establishment of the Pakistan Antarctic Programme.

Tomahawk (missile)

The Tomahawk (US /ˈtɑːməhɔːk/ or UK /ˈtɒməhɔːk/) is a long-range, all-weather, subsonic cruise missile named after the Native American axe. Introduced by McDonnell Douglas in the 1970s, it was initially designed as a medium to long-range, low-altitude missile that could be launched from a surface platform. It has been improved several times, and due to corporate divestitures and acquisitions, is now made by Raytheon. Some Tomahawks were also manufactured by General Dynamics (now Boeing Defense, Space & Security).

Description

The Tomahawk missile family consists of a number of subsonic, jet engine-powered missiles designed to attack a variety of surface targets. Although a number of launch platforms have been deployed or envisaged, only sea (both surface ship and submarine) launched variants are currently in service. Tomahawk has a modular design, allowing a wide variety of warhead, guidance, and range capabilities.

Variants

There have been several variants of the BGM-109 Tomahawk employing various types of warheads.

Operation Odyssey Dawn

Operation Odyssey Dawn was the U.S. code name for the American role in the international military operation in Libya to enforce United Nations Security Council Resolution 1973 during the initial period of 19–31 March 2011, which continued afterwards under NATO command as Operation Unified Protector. The initial operation implemented a no-fly zone that was proposed during the Libyan Civil War to prevent government forces loyal to Muammar Gaddafi from carrying out air attacks on Anti-Gaddafi forces. On 19 March 2011, several countries prepared to take immediate military action at a summit in Paris. Operations commenced on the same day with a strike by French fighter jets, then U.S. and UK forces conducting strikes from ships and submarines via 110 Tomahawk cruise missiles and air assets bombing Gaddafi forces near Benghazi. The goal of coalition forces has been to impose a no-fly zone and to destroy forces that threaten civilians – in effect this has meant forces loyal to Gaddafi.

Cruise missile submarine

A cruise missile submarine is a submarine that can launch cruise missiles (SLCMs). The United States Navy's hull classification symbols for cruise missile submarines are SSG and SSGN - the SS denotes submarine, the G denotes guided missile, and the N denotes that the submarine is nuclear-powered. Many cruise missile submarines retain the capability to deploy nuclear warheads on their missiles, but they are considered distinct from ballistic missile submarines due to the substantial differences between the two weapon systems characteristics. In modern usage, there is some significant overlap between cruise missile submarines and traditional attack submarines, as both cruise missile and dedicated anti-ship missiles greatly enhance a vessel's ability to attack surface combatants. Torpedoes are a more stealthy option, but missiles give a much longer stand-off range, as well as the ability to engage multiple targets on different headings at the same time. Early cruise missile submarines had to surface to launch their missiles. Later designs launch missiles from underwater, using either torpedo tubes or vertical canisters.
