Air Defence Identification Zone (ADIZ)Quick read


What is an Air Defence Identification Zone?

  • It is a zone which provides an early warning system to help a country detect possible incursions into its sovereign airspace. When an aircraft enters an ADIZ without warning, the country in question may scramble fighter jets to visually identify the aircraft and determine whether it poses a threat
  • In other words, ADIZ is airspace over land or water in which the identification, location, and control of civil aircraft are performed in the interest of national security.
  • The first ADIZ was established by the United States in 1950 when it created a joint North American ADIZ with Canada, citing the legal right of a nation to establish reasonable conditions of entry into its territory
  • The concept of an ADIZ is not defined in any international treaty and is not regulated by any international body
