This is a 1:24 scale model of the Little John, a U.S. Army surface-to-surface missile based on mobile launchers. It had a range of 10 miles and carried a conventional or nuclear warhead. It was deployed for only a few years in the early 1960s in Western Europe. The Army Ballistic Missile Agency built this model and donated it to NASM in 1961.
