Raytheon added semi active laser targeting to the M982 in the Excalibur S, so that 155mm shells could be directed in descent by apaches and reapers. The firing battery only has to get them in the ballpark.
They then added fire and forget capability with an onboard radar in the Excalibur N5, which is intended to be shot from the 5"/54 M45. Again, the firing battery only has to get it in the rough ballpark of where the target will be.

In short... we have the technology.
