"Since a regulation size football weighs 14 ounces, it was considered feasible to make a shaped charge grenade within this weight limitation. In addition, most US troops are familiar with throwing footballs," according to the Army's test report for the weapon.
Designing the explosive was a simple task, but not a well-thought-out one. The Army simply hollowed out a Nerf football and shoved the explosive charge inside. While the weight of the football was the same, the passer didn't enjoy the same accuracy a Roger Staubach might have enjoyed on the gridiron.
