ELI5: What is a bunker-buster bomb?

A bunker-buster bomb is a super strong bomb that's made to explode inside of things that are built to be super strong, like underground hideouts.

Imagine you're building a fort in your backyard. You use blankets, pillows, and maybe even some wood to make it really tough. Now, imagine someone wants to knock down your fort.

• A regular water balloon might not do much, just get the blanket wet.
• But a bunker-buster bomb is like a giant water balloon filled with rocks and launched from a super-powered slingshot.

• First, it's really heavy and made of strong metal, so it can smash through the roof of your fort (or a real bunker). This is like the rocks in the water balloon helping it break through.
• Second, it has a special fuse. Instead of exploding when it hits the fort, it waits a little bit. This is like the slingshot launching the water balloon really high, so it has time to reach the center of the fort.
• Then, BOOM! It explodes inside, causing way more damage than if it exploded on the outside. This is because the explosion is trapped inside, and the walls of the fort help to spread the force of the explosion.
