This bomb is designed to kill 40 tanks at once

The CBU-105 cluster bomb is a devasting tank-killer. One bomb can carpet an area of 1,500 by 500 feet, roughly 15-acres.

But unlike traditional cluster bombs, the CBU-105 is considered a “smart bomb.” The weapon can destroy multiple moving or stationary threats with minimal collateral damage while leaving no hazardous unexploded ordnance on the battlefield.

Its BLU-108 submunition cylinders use infrared and laser sensors to seek and destroy targets by pattern-matching. If it fails to find a target, the skeet warhead within the bomb self-destructs. And if the self-destruct system fails, a backup timer disables the skeet. The disabled skeets that make it to the ground also have an inert feature, which make it resistant to exploding via tampering, according to Textron.
