The US Military's Worst Idea

Summary by Krater

The video tests whether a 100 kg metal rod dropped from a helicopter onto a sand castle city can act as a kinetic weapon like the theoretical Project Thor, concluding that while kinetic impacts at high speed generate massive energy, aiming them accurately is extremely difficult in practice.

From the video

Answers: Can kinetic rods from god actually work as weapons?

• Project Thor
• Rods from God
• Kinetic energy weapons
• Hypersonic weapon drop testing
• Satellite constellation defense limits

What it concludes

• Dropping a 100 kg metal rod from 500 meters gave it an impact speed of 350 km/hr and nearly half a million joules of kinetic energy.
• A 200 kg metal rod dropped from 150 feet directly hit and cracked a building in a sand castle city.
• Steering a rod from God in practice is extremely difficult due to hypersonic speeds and superheated plasma shrouding the projectile.
• Deploying a constellation of space-based kinetic interceptors to defend against ICBMs would cost hundreds of billions of dollars and remain prone to being evaded by simultaneous missile launches.
