Why Did China Establish Its Own ADIZ

防空识别区由来

1940年，美国曾提出“沿海岸线建立对空监视网”的设想。

二战结束后，以美、苏为代表的军事强国大批列装高速喷气式战机，此举对各国传统防空体系构成巨大威胁。

为扩大预警距离，增加反应时间，上世纪50年代，美国和加拿大划定了世界上第一个防空识别区——北美防空识别区。

后来，由于洲际导弹的诞生以及苏联解体，北美防空识别区的地位降低，但随着“9 11”事件的出现，防空识别区在近十年再次获得了重视。

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.
