　　防空識別區由來

1940年，美國曾提出“沿海岸線建立對空監視網”的設想。

二戰結束后，以美、蘇為代表的軍事強國大批列裝高速噴氣式戰機，此舉對各國傳統防空體系構成巨大威脅。

為擴大預警距離，增加反應時間，上世紀50年代，美國和加拿大劃定了世界上第一個防空識別區——北美防空識別區。

后來，由于洲際導彈的誕生以及蘇聯解體，北美防空識別區的地位降低，但隨著“9 11”事件的出現，防空識別區在近十年再次獲得了重視。

The origin of ADIZs

In 1940, the United States proposed the idea of "establishing a network for airspace vigilance along its coasts." After World War II, military powers led by the U.S. and the Soviet Union put a large number of high-speed jet fighters into service, which put a number of countries' traditional air defense at risk.

To increase the response distance and time for an early warning, the U.S. and Canada established the world's first-ever ADIZ – the North America Air Defense Identification Zone.

Later, after ICBMs were developed and the Soviet Union had been dissolved, the North American ADIZ became less important. However, the 9/11 attacks have once again made ADIZs an important issue over the last decade.
