The MGR-1 Honest John was the first surface to surface rocket in the U.S. Army that could carry a nuclear warhead. Designed for close support of front line troops its launcher was designed to be mounted on a standard U.S. Army truck. With no electronic guidance systems Honest John was a simple and mobile point and shoot delivery system that packed a bigger punch than standard artillery guns.
To expand the support Honest John could provide to front line troops several different types of non-nuclear warheads were developed including conventional, chemical, and anti-personnel variants.
