U.S. military's fighter fleet

Defense officials said a U.S. Air Force F-15 crashed Wednesday, October 8, 2014, in England. Here, an F-15E Strike Eagle flies during a demonstration in 2007 near Indian Springs, Nevada. The F-15E was designed for long-range, high-speed interdiction without relying on escort or electronic warfare aircraft. It was derived from the F-15 Eagle, which was developed to enhance U.S. air superiority during the Vietnam War.
