The withdrawl of Argentine AD assets from the south to defend Buenos Aires from a potential Vulcan attack is often cited as an effect of the Black Buck raid. It would be interesting to know if demonstrating the ability to threaten BA was really intended by those who first conceived Black Buck. Furthermore, did anyone really predict that these raids might keep the Mirage IIIs out of the way? Or was it a lucky bonus? I suppose the cabinet papers that will be released in 2012 (30 year rule) might shed some more light.
As to doing the like again. Today's tanker force can put considerably more fuel in the air than the Victor force could in 1982. However, once the TriStar and VC10 have been replaced by FSTA this total will drop below the 1982 level, albeit with less being used by tankers themselves. More significantly though, and unlike just about every new tanker type that is being procured around the world, our tankers will not be able to refuel each other. Thus the fuel will only be able to be delivered to a point within the basic radius of action of the tanker. There would be no clever tanker-tanker stuff like the good old Victor boys achieved. How's that for progress?
