Multiple independently targetable reentry vehicle

Have you ever seen a rocket shoot into the sky? Well, some special rockets are like a surprise party in the sky! They carry many small 'bombs' called warheads.

The coolest part is that each warhead can be aimed at a totally different place. It’s like having a bunch of tiny arrows that can all fly to different targets at the same time! These super rockets are called MIRVs, which is a long name for a very clever idea.

A long, long time ago, rockets only carried one warhead. But then, smart scientists thought, 'What if we could send more?' So, they invented the MIRV rocket! The first one that could do this trick was called Minuteman III, and it started flying in 1970. It was like a big upgrade, making rockets much more powerful because they could hit many places at once instead of just one.

These rockets are important because they can hit many targets with just one launch. Imagine if you had to throw one ball at a time to knock down five pins. A MIRV rocket is like being able to throw five balls at once, each going to a different pin! This made countries think very carefully about what they were doing, because one rocket could cause a lot of trouble in many places.

Inside the big rocket, there's a special part that holds all the smaller warheads. When the rocket gets high up in space, this part opens up! Then, each little warhead can be steered to its own special target. It’s like a delivery truck that can drop off packages at many different houses on one trip. This makes them very tricky to defend against!
