The United States and British navies have some pretty incredible military technology at their disposal. One of the best strategic military technologies that the United States and their allies have developed is the ability to fire ballistic missiles from a submarine. This isn’t a particularly new technology but advances and upgrades are being made to this technology every day.  The addition of supersonic and hypersonic cruise missiles to these subs is in the pipeline. Vessels such as the Ohio class submarine, as featured in a couple Tom Clancy novels, carry Trident-II intercontinental ballistic missiles or ICBM’s. The Trident II has 8 independently targeted reentry vehicles or a MIRV setup as it is called, all of which can carry warheads to different targets. The Ohio class submarine is what makes up a lot of the United States nuclear weapons threat. The United States has 18 Ohio Class submarines in its arsenal serving as a friendly reminder to any hostile nations. Check out the video below of a British submarine with similar ICBM technology to the Ohio class fire a missile while submerged.
