The Soviet Union sent Sputnik into space in 1957. By 1958, thanks in part to the work of famed scientist Carl Sagan, the Pentagon had a plan to show the commies what for by nuking the moon. Thankfully, it was just a plan. One that the U.S. never acted on. But it’s far from the only military scheme the US and others cooked up over the years. From bat bombs to an aircraft carrier built from an iceberg, military history is full of outlandish and ridiculous schemes best left abandoned at the planning stages.
