Homing beacon

The homing beacon is a unique weapon in Fallout 4. Rather than dealing damage directly, it calls a strike from a warhead aboard the Yangtze.

Gameplay
When thrown, a warhead will launch, landing in the same spot as the beacon was thrown. The beacon is thrown at a speed faster than any other thrown weapon, but cannot be utilized in tight spaces, deep quarries, or inside buildings. If the beacon is used in an open area with buildings nearby, there is a chance the nuke will hit the roof of a building or a tree. The beacon can be reverse-pickpocketed into the inventory of an enemy and still work, however only one beacon can be active while in the enemy's inventory.

Location
Three are given by Captain Zao as a reward after completing the quest Here There Be Monsters.
