Fighter jets have long been a staple of any successful military campaign. They are fast, effective, expensive and highly lethal machines, capable of traveling long distances with enormous firepower and guns. This article introduces us to the five top military jet fighters in service today, the price we pay for them, and the future of jet fighting aviation. Only fighter jets that made it into active duty were considered, therefore the YF-23 Black Widow, the YF-17 Cobra, and the F-20 Tigershark were excluded. Additionally, only fighter jets were examined and therefore bombers such as the F-117 Nighthawk and the F-21 Kfir were also not included.
