The air defense system reached its peak in 1962.
If radio interrogation failed to identify an aircraft in the ADIZ, the Air Force launched interceptor aircraft to identify the intruder visually. An air defense command and control structure was developed in 1950, creating five air defense identification zones around North America. Under US law and policy, the zone applies only to commercial aircraft intending to enter US airspace. Canada operates two other sections of the North American ADIZ, one off the Pacific coast of British Columbia and another that encompasses the Canadian Arctic Archipelago and its Atlantic provinces. ADIZ and the Alaska ADIZ, and two more overseas, the Hawaii ADIZ and the Guam ADIZ. The United States maintains two zones in North America the Contiguous U.S. The United States and Canada jointly operate an ADIZ that encompasses their sovereign airspace in North America.

Aircraft and surface-to-air missiles of the IAF, with elements of the Army and the Navy participating in their specific areas, where required, carry out interceptions. Military enforcement of ADIZs is solely the responsibility of the IAF, and the task is executed through a chain of radars as well as a C3I organisation. The zones have been declared over the international border with Pakistan, the international border with Nepal, over the Line of Actual Control with China, along the eastern borders with Bangladesh, Bhutan and MyanmarĪnd two in the southern region of India. India has demarcated six ADIZ near its territory. In case of delay, 45 or more minutes and a new Air Defence Clearance (ADC) numbers are required. Among other rules, notifications are required 10 minutes prior to entry.
India established ADIZs in the mid-twentieth century. Īir defense zones should not be confused with flight information regions (FIRs), which are used to manage air traffic. Usually, such zones cover only undisputed territory, do not apply to foreign aircraft not intending to enter territorial airspace, and do not overlap. As well, Russia and North Korea have unofficial zones.
About 20 countries and regions now have such zones, including Canada, India, Japan, Pakistan, Bangladesh, Finland, Norway, the United Kingdom, the People's Republic of China, South Korea, Taiwan, United States, Sweden, Iceland, and Iran.
The first ADIZ was established by the United States on December 27, 1950, shortly after President Truman had proclaimed a national emergency during the Korean War. The concept of an ADIZ is not defined in any international treaty and is not recognized by any international body. They are declared unilaterally and may extend beyond a country's territory to give the country more time to respond to possibly hostile aircraft.

Wider area of airspace where a country tries to identify, locate and control aircraftĪn air defense identification zone ( ADIZ) is the airspace of a country plus an additional wider area over land and water in which a country tries to identify, locate, and control any civil aircraft in the interest of national security.
