A no-fly zone, also known as a no-flight zone (NFZ), or air exclusion zone (AEZ), [1] is a territory or area established by a military power over which certain aircraft are not permitted to fly. Such zones are usually set up in an enemy power's territory during a conflict, similar in concept to a aerial demilitarized zone, and usually intend to prohibit the country's military aircraft from operating in the region. Aircraft that violate a no-fly zone may be shot down by the enforcing state, depending on the terms of the NFZ. Air exclusion zones and anti-aircraft defences are sometimes set up in a civilian context, for example to protect sensitive locations, or events such as the 2012 London Olympic Games, against terrorist air attack.


No-fly zones are a modern phenomenon established in the 1990s. They can be distinguished from traditional air power missions by their coercive appropriation of another nation's airspace only, to achieve aims on the ground within the target nation. While the RAF conducted prototypical air control operations over various contentious colonies between the two World Wars of the 20th century, no-fly zones did not assume their modern form until the end of the Gulf War in 1991. [2]

During the Cold War, the risk of local conflict escalating into nuclear showdown dampened the appeal of military intervention as a tool of U.S. statecraft. Perhaps more importantly, air power was a relatively blunt instrument until the operational maturation of stealth and precision-strike technologies. Before the Gulf War of 1991, air power had not demonstrated the "fidelity" needed to perform nuanced attacks against transitory, difficult-to-reach targets—it lacked the ability to produce decisive political effects short of total war. However, the demise of the Soviet Union and the rise in aerospace capabilities engendered by the technology revolution made no-fly zones viable in both political and military contexts. [2]

Past no-fly zones

Iraq, 19912003

Following the 1991 Gulf War, the United States along with other Coalition nations established two no-fly zones in Iraq. [3] U.S. and Coalition officials stated that the northern no-fly zone was intended to prevent attacks against the Kurdish people by the Iraqi regime of Saddam Hussein, and that the southern no-fly-zone was intended to protect Iraq's Shia population. On March 16, 1988, the Iraqi Air Force deployed chemical weapons against Kurdish civilians during the Halabja chemical attack, killing 5,000. This air-to-ground event served as part of the motivation used by Coalition Forces in order to extend and expand the NFZs, as well as citing parts of Chapter 42 within the U.N. Charter. The southern no-fly zone originally extended to the 32nd parallel [4] but was extended to the 33rd parallel in 1996. [5]

This military action was not authorised by the United Nations. [6] The Secretary-General of the United Nations at the time the resolution was passed, Boutros Boutros-Ghali called the no-fly zones "illegal" in a February 2003 interview with John Pilger for ZNet. [7] [8] In 1998, France withdrew from the operation, [3] with French Foreign Minister Hubert Vedrine saying that "there is no basis in international law for this type of bombing". [6]

Civilian deaths

The United Nations reported that in 1999 alone 144 civilians had been killed during Coalition bombing efforts. [9] Reports from Baghdad claim that more than 1,400 civilians were killed. [10] An internal UN Security Sector report found that, in one five-month period, 41% of the victims were civilians. [11]

Bosnia and Herzegovina, 19931995

In 1992, the United Nations Security Council passed United Nations Security Council Resolution 781, prohibiting unauthorized military flights in Bosnian airspace. This led to Operation Sky Monitor, where NATO monitored violations of the no-fly zone but did not take action against violators of the resolution. In response to 500 documented violations by 1993, [12] including one combat violation, [13] the Security Council passed Resolution 816, which prohibited all unauthorized flights and allowed all UN member states to "take all necessary ensure compliance with [the no-fly zone restrictions]." [14] This led to Operation Deny Flight. NATO later launched air strikes during Operation Deny Flight and during Operation Deliberate Force.

Lessons from Iraq and Bosnia

A 2004 Stanford University paper published in Journal of Strategic Studies, "Lessons from Iraq and Bosnia on the Theory and Practice of No-fly Zones," reviewed the effectiveness of the air-based campaigns in achieving military objectives. The paper's findings were: 1) A clear, unified command structure is essential. In Bosnia and Herzegovina, during "Operation Deny Flight," a confusing dual-key coordination structure provided inadequate authority and resulted in air forces not being given authority to assist in key situations; 2) To avoid a "perpetual patrol problem," states must know in advance their policy objectives and the exit strategy for no-fly zones; 3) The effectiveness of no-fly zones is highly dependent on regional support. A lack of support from Turkey for the 1996 Iraq no-fly zone ultimately constrained the coalition's ability to effectively enforce it. [15]

Libya, 2011

2011 no-fly zone in Libya

As part of the 2011 military intervention in Libya, the United Nations Security Council approved a no-fly zone on 17 March 2011. The resolution includes provisions for further actions to prevent attacks on civilian targets. [16] [17] NATO seized the opportunity to take the offensive, bombing Libyan government positions during the civil war. The NATO no fly zone was terminated on 27 October after a unanimous vote by the UNSC. [18]

Libya, 2018 and 2019

A no-fly zone was declared by the Libyan National Army (LNA) in the country's south during the LNA's offensive in the region in 2018. [19] It was later re-implemented for 10 days in 2019 as the LNA established control over oil fields in the region. [20] The LNA declared another no-fly zone in the country's west, during the 2019 Western Libya offensive. [21]

Iraqi no-fly zones conflict no-fly zones in Iraq proclaimed by the USA, UK and France between 1991–2003

The Iraqi no-fly zones conflict was a low-level conflict in the two no-fly zones (NFZs) in Iraq that were proclaimed by the United States, United Kingdom, and France after the Gulf War of 1991. The United States stated that the NFZs were intended to protect the ethnic Kurdish minority in northern Iraq and Shiite Muslims in the south. Iraqi aircraft were forbidden from flying inside the zones. The policy was enforced by U.S., British, and French aircraft patrols until France withdrew in 1996.

Operation Deliberate Force

Operation Deliberate Force was a sustained air campaign conducted by the North Atlantic Treaty Organisation (NATO), in concert with the United Nations Protection Force (UNPROFOR) ground operations, to undermine the military capability of the Army of Republika Srpska (VRS), which had threatened and attacked UN-designated "safe areas" in Bosnia and Herzegovina during the Bosnian War with the Srebrenica and Markale massacres, precipitating the intervention. The shelling of the Sarajevo market place on 28 August 1995 by the VRS is considered to be the immediate instigating factor behind NATO's decision to launch the operation.

Operation Deny Flight 1993–1995 NATO operation in Bosnia and Herzegovina

Operation Deny Flight was a North Atlantic Treaty Organization (NATO) operation that began on 12 April 1993 as the enforcement of a United Nations (UN) no-fly zone over Bosnia and Herzegovina. The United Nations and NATO later expanded the mission of the operation to include providing close air support for UN troops in Bosnia and carrying out coercive air strikes against targets in Bosnia. Twelve NATO members contributed forces to the operation and, by its end on 20 December 1995, NATO pilots had flown 100,420 sorties.

Libyan Air Force Air warfare branch of Libyas armed forces

The Libyan Air Force is the branch of the Libyan military responsible for aerial warfare. In 2010, before the Libyan Civil War, the Libyan Air Force personnel strength was estimated at 18,000, with an inventory of 374 combat capable aircraft operating from 13 military airbases in Libya. Since the 2011 civil war and the ongoing conflict, multiple factions fighting in Libya are in possession of military aircraft. As of 2019 the Libyan Air Force is nominally under the control of the internationally recognised Government of National Accord in Tripoli, though the rival Libyan National Army of Marshal Khalifa Haftar also has a significant air force.

Operation Sky Monitor

Operation Sky Monitor was a NATO mission to monitor unauthorized flights in the airspace of Bosnia and Herzegovina during the Bosnian War. The operation began in response to United Nations Security Council Resolution 781, which established a ban on the use of military aircraft in Bosnian airspace, and requested the aid of member states in monitoring compliance. Beginning on October 16, 1992, NATO monitored violations of the no-fly zone using E-3 Sentry NAEW aircraft based in Germany, Italy, Greece, and the United Kingdom. The operation documented more than 500 violations of the no-fly zone by April 1993. In response to this high volume of unauthorized flights, the Security Council passed Resolution 816, which authorized NATO to enforce the no-fly zone, and engage violators. In response, NATO deactivated Sky Monitor on April 12, 1993, transferring its forces to the newly established Operation Deny Flight.

NATO intervention in Bosnia and Herzegovina

The NATO intervention in Bosnia and Herzegovina was a series of actions undertaken by NATO whose stated aim was to establish long-term peace during and after the Bosnian War. NATO's intervention began as largely political and symbolic, but gradually expanded to include large-scale air operations and the deployment of approximately 60,000 soldiers under Operation Joint Endeavor.

2011 military intervention in Libya 2011 NATO military intervention in Libya

On 19 March 2011, a multi-state NATO-led coalition began a military intervention in Libya, to implement United Nations Security Council Resolution 1973, in response to events during the Libyan Civil War. The United Nations' intent and voting was to have "an immediate ceasefire in Libya, including an end to the current attacks against civilians, which it said might constitute crimes against humanity ... imposing a ban on all flights in the country's airspace – a no-fly zone – and tightened sanctions on the [Muammar] Gaddafi regime and its supporters."

United Nations Security Council Resolution 1973

United Nations Security Council Resolution 1973, on the situation in Libya, is a measure that was adopted on 17 March 2011. The Security Council resolution was proposed by France, Lebanon, and the United Kingdom.

Operation Ellamy

Operation Ellamy was the codename for the United Kingdom participation in the 2011 military intervention in Libya. The operation was part of an international coalition aimed at enforcing a Libyan no-fly zone in accordance with the United Nations Security Council Resolution 1973 which stipulated that "all necessary measures" shall be taken to protect civilians. The coalition operation was designated by NATO as Operation Unified Protector, by the US as Operation Odyssey Dawn. The Canadian participation as Operation Mobile and the French participation as Opération Harmattan. It was confirmed in December 2011 that the cost of the operations was £212m – less than was estimated, including £67m for replacing spent munitions, is all expected to be met from the Treasury reserve.

Operation Unified Protector

Operation Unified Protector was a NATO operation in 2011 enforcing United Nations Security Council resolutions 1970 and 1973 concerning the Libyan Civil War and adopted on 26 February and 17 March 2011, respectively. These resolutions imposed sanctions on key members of the Gaddafi government and authorized NATO to implement an arms embargo, a no-fly zone and to use all means necessary, short of foreign occupation, to protect Libyan civilians and civilian populated areas.

The international reactions to the 2011 military intervention in Libya were the responses to the military intervention in Libya by NATO and allied forces to impose a no-fly zone. The intervention was authorized by United Nations Security Council Resolution 1973, approved in New York on 17 March, in response to the Libyan Civil War, though some governments allege participants in the operation exceeded their mandate.

The domestic reactions in the United States after the 2011 military intervention in Libya ranged from criticism to support. Unlike the revolutions in Tunisia and Egypt, which were carried out largely without external intervention, the brutal reaction of the Gaddafi regime to the protests that began in January and February 2011 quickly made it clear that the Libyan opposition forces would not be able to achieve political progress or to overthrow their government by themselves. In light of ongoing serious human rights violations, the United Nations Security Council established a no-fly zone over Libya and authorized the member states of the UN to take all necessary measures to protect civilians and civilian populated areas under threat of attack. Two days later, a coalition of states—including the United States, the United Kingdom, and France—began to carry out air strikes against military targets in Libya. By the end of March 2011, NATO had taken over the international military operation in Libya. With the support of NATO, the insurgents successively took power in Libya, gaining control over the capital, Tripoli, in August and over Sirte, the last city held by the Gaddafi regime, in October 2011. During the fights over Sirte, Gaddafi was killed. With the insurgents taking control over most of the country and being recognized as the legitimate (transitional) government of Libya by much of the international community, a change in the Libyan regime has taken place.
