This is a model of unknown scale of the Sidewinder, an air-to-air missile originally developed for the U.S. Navy in the early 1950s. One of many versions produced through the years, the AIM-9D was built by Raytheon and had a conventional warhead, a solid-fuel motor, infrared guidance, a maximum speed of Mach 2.5, and a range of 11 miles. Limited numbers were deployed with the U.S. Air Force during the 1960s. The other versions of the Sidewinder have been deployed on a wide variety of U.S. Navy and U.S. Air Force aircraft, as well as being exported to a number of allied nations. John and Cynthia Heyde donated this model to NASM on an unknown date.
This object is on display in James S. McDonnell Space Hangar at the Steven F. Udvar-Hazy Center in Chantilly, VA.
