北美防空司令部

当二战结束时，美国还没感到空袭的威胁，因此一直没有设置防空机构，直到1947年底，美国空军才正式成立了防空司令部，执行防空作战任务。

由于加拿大位于美国的北方，因此若与加拿大共同投资，建成能统一对付苏联的防空系统，那么在美国的北方就可以形成一道防空屏障。而加拿大则想利用美国的财政和技术优势，落得一个“大树底下好乘凉”。因此两个国家在相互利用的心态下，从1954年开始筹建能统一指挥北美大陆防空力量的防空机构。1958年5月12日，美加两国签订了《北美防空司令部》协议，宣布“授权一个统一司令部对两国提供的防空作战部队实施作战控制”，并将建立“北美防空司令部”。

北美防空司令部是一个以美国为主体，联合加拿大组成的多兵种联合防空司令部，其总部设在美国科罗拉多州的彼得森空军基地，司令由美国一位空军四星上将担任，副司令由加拿大空军司令担任，它直属美军参谋长联席会议领导。

《北美防空司令部》协议有效期为10年，期满后继续延长。为适应“空间监视、导弹警戒等有关职责”，1981年5月12日美国和加拿大又签订了《北美防空防天司令部》协议，协议中规定把“北美防空司令部”改名为“北美防空防天司令部”。

美国航天司令部

美国三军先后建立了航天司令部，为统一管理三军的航天活动，于1985年9月1日成立了美国航天司令部，总部设在彼得森空军基地，其司令兼任北美防空防天司令部的司令。

不相信中文资料没关系，看美国人自己写的：

The North American Aerospace Defense Command (NORAD) is a bi-national United States and Canadian organization charged with the missions of aerospace warning and aerospace control for North America. Aerospace warning includes the monitoring of man-made objects in space, and the detection, validation, and warning of attack against North America whether by aircraft, missiles, or space vehicles, through mutual support arrangements with other commands. Aerospace control includes ensuring air sovereignty and air defense of the airspace of Canada and the United States. The May 2006 NORAD Agreement renewal added a maritime warning mission, which entails a shared awareness and understanding of the activities conducted in U.S. and Canadian maritime approaches, maritime areas and inland waterways.

To accomplish these critically important missions, NORAD continually adjusts its structure to meet the demands of a changing world. The commander is appointed by, and is responsible to, both the U.S. president and the Canadian prime minister. The commander maintains his headquarters at Peterson Air Force Base, Colo. The NORAD-U.S. Northern Command (USNORTHCOM) Command Center serves as a central collection and coordination facility for a worldwide system of sensors designed to provide the commander and the leadership of Canada and the U.S. with an accurate picture of any aerospace threat. Three subordinate regional headquarters, located at Elmendorf Air Force Base, Alaska, Canadian Forces Base, Winnipeg, Manitoba, and Tyndall Air Force Base, Florida, receive direction from the commander and control air operations within their respective areas of responsibility.

To accomplish the aerospace warning mission, the commander of NORAD provides an integrated tactical warning and attack assessment to the governments of Canada and the United States. To accomplish the aerospace control mission, NORAD uses a network of satellites, ground-based radar, airborne radar and fighters to detect, intercept and, if necessary, engage any air-breathing threat to North America. As a part of its aerospace control mission, NORAD assists in the detection and monitoring of aircraft suspected of illegal drug trafficking. This information is passed to civilian law enforcement agencies to help combat the flow of illegal drugs into North America. The command is currently developing a concept for implementing the new maritime warning mission.

Through outstanding bi-national cooperation, NORAD has proven itself effective in its roles of watching, warning, and responding. NORAD continues to play an important role in the defense of Canada and the U.S by evolving to meet the changing threat. The events of September 11, 2001 demonstrated NORAD’s continued relevance to North American security. Today, NORAD provides civil authorities with a potent military response capability to counter domestic airspace threats.

While the national leadership of Canada and the U.S. continue to refine our response to the terrorist threat, NORAD’s proven abilities and unique capabilities will remain a vital part of homeland defense.
