Watch as epic battles are waged on land and in the air to determine history's most powerful weapons of war. Four of the greatest fighters are pitted against each other in a series of tests to prove which is the fastest, most accurate, most powerful fighting machine. Pilots, gunners, and experienced vets put each weapon through its paces, measuring every technical aspect, then debate the real-world impact-how it actually fared in the field.
