Can one aircraft guide weapons launched by another platform?

Could an aircraft guide missiles or weapons launched by another platform?

Yes. Modern datalinks can share sensor data and firing solutions so that one platform detects a target while a different, better-positioned platform launches the weapon.

A grid of sensors and shooters replaces a closed chain in which every aircraft must find and attack its own target. A ship, satellite, fighter, or airborne early-warning aircraft can contribute observations that are fused into a targeting solution. A decision-maker can then assign the most appropriate available shooter. The model increases the value of support aircraft because their sensors and command functions improve weapons carried throughout the task group.
