Air Defense Law and Legal Definition
Air defense means all defensive measures intended to destroy attacking enemy aircraft or missiles in the earth’s envelope of atmosphere, or to nullify or reduce the strength of such attack. The term air defense was first used by Britain in 1925, when Air Defense of Great Britain (ADGB) was created as a Royal Air Force command. It can be used to protect the naval, ground, and air forces in every case. It includes ground and air based weapon systems, associated sensor systems, command and control arrangements, and passive measures.
