Ward is wrong about the 2nd Black Raid, as this photo which was taken by one of his own pilots from 801NAS in late May 82 proves!!!!! (He is right about a Vulcan dropping the bombs fused wrongly (they were armed however), however it didn't happen in May 82, which kind of cuts down the options on guessing which Black Buck raid it was).
The real strategic hit that the Vulcan could have put in would have been if that Shrike fired at the TPS-43F on the first Black Buck ARM mission hit that radar head on (just slightly damaged it apparently). That would have been a real game changer as it would blinded the Argentine to all of our air movements around the Islands for the later part of the war. The TPS-44 that the Argentine Army used on the Islands was U/S for most of the war after taking a near miss from a 4.5 inch shell on 11 May according to an Argentine operator of the equipment who posted his account of what happened to him in 82 on another froum.
