civil air defense project
Civil air defense works used to be called "air-raid shelters", including underground protective buildings built separately for wartime protection of personnel and materials, civil air defense command and medical rescue, and basements built in combination with ground buildings that can be used for air defense in wartime. It can resist various killing factors such as shock wave, thermal radiation, nuclear radiation and conventional explosion debris. Civil air defense projects are equipped with explosion-proof valves, protective doors, dust filters, poison filters and other equipment and facilities, which can prevent toxic agents, radioactive and biological warfare agents from polluting the air and ensure the needs of personnel for clean air and access to the project.
Air raid warning
Air defense warning is an important means of air defense organization and command. It is usually used for disaster prediction and emergency notification in case of sudden major accidents in emergency rescue and disaster relief, and it is an alarm signal for people's governments at all levels to organize and prevent air strikes in wartime.
"new three defenses" and "old three defenses"
The so-called "old three defenses" refers to the protection of nuclear weapons, chemical weapons and biological weapons. It is an effective way to destroy the enemy and protect yourself.
The so-called "new three defenses" means preventing precision strikes, electronic interference and reconnaissance and surveillance. For important economic targets, we should disperse, multiply and go underground, and take comprehensive measures such as hidden defense, confusing defense and electromagnetic defense. This is put forward in view of the characteristics of modern warfare. Anti-reconnaissance and surveillance are mainly to prevent precision strikes and information attacks.
Modern air strikes, including high-tech conventional weapons attacks and nuclear, chemical and biological weapons attacks, are all attacks on ground (sea) targets from the air. High-tech conventional air attack mainly refers to the precise attack on the target with precision guided weapons. The main targets of air strikes are the head office, power supply, gas supply, water supply, transportation, communication hub and important military facilities.
