This is a model of unknown scale of the Walleye, an air-launched glide bomb that has no propulsion system. Initially developed in the 1960s by Martin Marietta for the U.S. Navy, the first versions were television-guided from the launch aircraft and were utilized by both the Navy and Air Force in Vietnam. Later versions of the Walleye have more advanced systems that permit either the launch aircraft or secondary aircraft to guide the bomb to its target. These later versions saw service in the Gulf War. John and Cynthia Heyde donated this model to NASM on an unknown date.
