Archer and Arrow
I think the Darings can kill the archer.. even over the horizon. But you wouldn't want to risk it unless the environment was completely clean of Boeings and Airbuses. So for most real life situations you need a CAP / AEW to get out there and spot and plot the bad guys before they get close.
So in the old Falklands scenario ... yes a 45 could take a shot at the first pop up and hopefully get the archer too.
