ICBM

Intercontinental Ballistic Missile. A ballistic missile with a range of more than 5500km. After the long range ballistic missiles are launched, they accelerate for several minutes and then draw a parabolic orbit in the sky, driven by inertia as they travel to their destination. They were defined during SALT (Strategic Arms Limitation Talks), which were held from 1969 to 1972 between the USA and the Soviet Union. The countries said to possess ICBMs are the USA, the Soviet Union, and the People's Republic of China.
