That's how Project Thor came to be.

Instead of hundreds of small projectiles from a few thousand feet, Thor used a large projectile from a few thousand miles above the Earth. The "rods from god" idea was a bundle of telephone-pole-size (20 feet long, 1 foot in diameter) tungsten rods, dropped from orbit, reaching a speed of up to 10 times the speed of sound.

The rod itself would penetrate hundreds of feet into the Earth, destroying any potential hardened bunkers or secret underground sites. More than that, when the rod hits, the explosion would be on par with the magnitude of a ground-penetrating nuclear weapon — but with no fallout.

It would take 15 minutes to destroy a target with such a weapon.

One Quora user who works in the defense aerospace industry quoted a cost of no less than $10,000 a pound to fire anything into space. With 20 cubic feet of dense tungsten weighing in at just over 24,000 pounds, the math is easy. Just one of the rods would be prohibitively expensive. The cost of $230 million a rod was unimaginable during the Cold War.

These days, not so much. The Bush administration even considered revisiting the idea to hit underground nuclear sites in rogue nations in the years following 9/11. Interestingly enough, the cost of a single Minuteman III ICBM was $7 million in 1962, when it was first introduced ($57 million adjusted for inflation).

The trouble with a nuclear payload is that it isn't designed to penetrate deep into the surface. And the fallout from a nuclear device can be devastating to surrounding, potentially friendly areas.

A core takeaway from the concept of weapons like Project T
