If the German Luftwaffe had maintained air superiority in all theaters, the conversation around the Tiger would be much different today. Tanks need protection from aircraft. T2's were massacred in the Falaise, and in the retreat from the Ardennes mainly by airpower.
The T1, in tank to tank engagements around Caan, acquitted themselves admirably, but could not defend against allied air. Pz. Abt. 101 is a point in case.
Agreed although had the Luftwaffe maintained air superiority on all fronts D-Day would never have happened, the Afrika Korps would have controlled the Middle East oilfields and Russia would have been in deep trouble.
However I am still to be convinced that fighter-bombers had as big an impact on tanks as is commonly thought.
If you look at Zetterling's book Normandy 1944 the Germans lost around 1500 AFV's (Tanks, Tank Destroyers, Assault Guns) of which only about 7% were determined to have been by aircraft.
In the Goodwood area a total of 456 German heavily armoured vehicles were counted, and 301 were examined in detail. They found only 10 could be attributed to Typhoons using RPs (less than 3% of those claimed), only 3 out of 87 APC examined could be attributed to air lunched RPs.
At Mortain it turns out that only 177 German tanks and assault guns participated in the attack, (75 less tanks than claimed as destroyed by aircraft) of these 177 tanks, 46 were lost and only 9 were lost to aircraft attack. Around 4% of those claimed.
When the results of the various Normandy operations are compiled, it turns out that no more than 100 German tanks were lost in the entire campaign from hits by aircraft launched ordnance.
Thus on a single day in August 1944 the RAF claimed 35% more tanks destroyed than the total number of German tanks lost directly to air attack in the entire campaign.
Or to be blunt the weapon that proved the most lethal to German armour was artillery not aircraft.
