Ever wonder whether a hostile enemy could successfully hit our soil with a missile? If a war were to occur it could be a very likely threat, yet the probability of it being successful is very small.
This is thanks to new technologies such as the Sea-based X-band Radar system that has been put in place at Adak Island, Alaska. This radar system is so powerful that it could track virtually any moving object anywhere in America.
This means that if a missile were to be sent at American soil, the X-Band would most likely see it long in advance. X-Band radars operate on a wavelength of 2.5-4 cm and are often used to detect such tiny objects as water particles and light!
Although the X-Band frequency is usually used for determining future weather, it is has now been engineered for military purposes.
