This is a model of unknown scale of the Bulldog AGM-12C, an air-to-ground missile also known as the Bullpup B. Initially developed by Texas Instruments for use by U.S. Navy carrier-based aircraft, it had a range of 10 miles, a 1,000 lb conventional warhead, and utilized radio guidance from the launch aircraft. The missile also was deployed with the U.S. Air Force from 1965 until the mid-1970s, and saw service on F-4 and F-105 fighters during the Vietnam War. 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.
