It is an option that I've been wondering about too, but doesn't go very far.
When the Hitler guy issued his order about the Me-262 being hurridly dedicated to forthcomnig Allied landing beaches surprise attack, the deciding German staff, having no choice, should have complied. And instantly re-raise the He-280 program. To get a good jet fighter at the soonest.
While the Me-262 was certainly a more potent bomber zerstörung thing and a general employ heavy fighter, AH orders being AH orders, stupid or not so, re-enliving the He-280 would be an appealing option for them : to keep an advanced jet fighter at soonest on the scene.
When we think that the heavy concrete V-1 -1st generation- massive launching sites played such a good role as a deception, for RAF Bomber Command change of priorities, the He-280 too in West Europe could have played a part in attracting the Lancs, perhaps tearing their effort against numerous V1 big-concrete fearsome installations, and most worrisome long-runwayed bases for the He-280s... ?
Deployed well in western France, those long-runway He-280 bases like their V1 big-concrete conterparts, would have attracted Allied strategic attention and in themselves put a main problem for the planned Overlord operation.
They, short of any better, could have played an excellent strategic shield for the hidden, secret effort for the Me-262 'beach surprise'.
This the best, 100% luck, most optimistic plan the Germans could raise.
Less than a 100 He-280 could do.. Being in themselves a very dangerous weapon, at least in the fighter vs fighter game. A problem that the Allied planners had to adress..
But then when you think of it :
- Yes the Allied would have 'adressed' it !
- Too few He-280 + too few Me-262 'beach-bombers' = little effect.
Although, much worry... It then depends on who has the nerves.
I don't think the Allied were the ones to hold doubts.
