討論內容: Three years http://experiencefoundation.com/online-will-writing/ write a college paper On October 26, 2001, the Pentagon announced that it had chosen Lockheed Martin over Boeing to build what Lockheed promised would be 璽??the most formidable strike fighter ever fielded.璽?? The Pentagon璽??s ask was huge: Build us a next-generation strike-fighter aircraft that could be used not only by the U.S. military but also by allied nations (which would come to include the United Kingdom, Italy, the Netherlands, Turkey, Canada, Australia, Denmark, Norway, Japan, and Israel). On top of that: Produce three versions of the airplane璽??a conventional version for the air force, a short-takeoff and vertical-landing version for the Marines, and a carrier-suitable version for the navy. The idea was that a single stealthy, supersonic, multi-service airplane could entirely replace four existing kinds of aircraft. And the expectation was that this new airplane would do everything: air-to-air combat, deep-strike bombing, and close air support of troops on the ground.
