Apparently Stanley airfild wss built on a solid bedrock base, so bombs dropped from high altitude would only scab a bit off the top rather than penetrate and cause 'heave' and lower level bombs landed at oblique angles and tended to skip before exploding. It was a difficult runway to knock out.
On the contrary, the 1,000 lbers dropped from height cratered nicely - indeed, the crater from Black Buck I was found to be back filled with rubble and a good many oil drums when 59 Commando Squadron Royal Engineers began repairs. The other four craters, resulting from low level retarded attack, were less deep, although craters nonetheless, & additionally, there were over a thousand 'scabs' of the type to which you refer, caused mainly by submunitions & naval gunfire.
But, as Schlock & SsgtC say, all of this matters not one jot if your ability to store fuel, weapons and any number of other services and facilities essential for fast jet operations no longer exists.
And I don't fancy the chances of OTL's resupply flights by C-130 & F28 much in this TL, either.
*EDIT*
This is work beginning on an area of 'scabbing'. It might not be a crater in the true sense, but I wouldn't much fancy rolling over it in my Mirage III or Dagger at 150 knots..
