The F-15EX, also known as the eagle 2, is a next generation fighter aircraft being made boeing for the US air force. The F-15EX is the latest version of the F-15 Mission Design Series and is an upgraded version of the fourth generation F-15 fighter jet.
It has a single jet engine which thrusts it at supersonic speeds of over 1,300 mph, making it a revolutionary production for the US Air Force in the mid-1970's amidst the Cold War, being the most produced fighter jet for decades in the US.
In the 1970s, fighter jets went faster than our current fighter jets. The most modern American fighter jet, the Lockheed Martin F-35 Lightning II, can only go a top speed of 1,200 MPH.
