The first ICBM was installed at F.E. Warren Air Force Base. These powerful weapons continue to serve a critical role in the American nuclear arsenal in modern day. ICBMs can deploy up to 9,300 miles, which covers nearly any target in the world. Due to their powerful and deadly nature, ICBMs are considered a strategic defensive weapon.
