With the U.S. military being in the 3rd place in terms of active military personnel, it also has one of the most destructive weapons and it is no secret. All 4 branches (Navy, Marines, Army, and Air Force) are constantly developing and researching. And over the last century has evolved substantially, both in terms of personnel and technology.
It is fascinating to observe how much the U.S. military has evolved over the last decades and what destructive weapons they have developed. The most powerful weapons that the military has, will most likely not be used in case of a conflict, but they exist as a form of precaution and protection for the country.
These are the deadliest weapons that are currently part of the U.S. military arsenal.
