Making its Oshkosh debut is the AIM-9X Sidewinder missile, the most advanced infra-red tracking, short-range air-to-air missile in the world. It is in use by 40 countries, and arms U.S. Navy and U.S. Air Force F-15, F-16 and F-18 aircraft. The one mounted here on a Aero Vodochody L-39C jet is, of course, just a dummy. Credit: Mo Spuhler
