Fine to see you´re back, Glider!
Yes, yes, in an interception mode at altitude, the Meteor-III could be amazing and very well suited for hi alt interceptions.
I also agree in your view on Stalin. It´s interesting that he also ignored Dr. Sorge, his best spy (probably the most important of ww2), who informend him detailed about what forces at what times are ordered to attack the SU. That are informations from at least two different sources! After all I read, only the commanding chief of the southern military region (Odessa) Gen. F.G. Mitschugin was concerned by these informations and ordered the forces to decentralize and hide. The Luftwaffe attacks seems to be quite unsuccesful here, only 6 planes have been destroyed on the ground as far as known (with an uncertainity because of the unpublished VVS-losses, source is Gröger´s history of aerial dogfight from 1982) plus an unknown number in the air.
The question is could the RAF with it´s ground forces move so far to overtake airfields closer to allow strikes against Moscow? I see this problematic, as I pointed out, the RAF has no Blitzkrieg tactics developed, esspeccially in 1941. They simply lacked GA-planes. Not to say that they did not had, but the numbers are simply insufficient to cover ground ops (and that´s what counts over Russia) effectively. A concentration of RAF forces might give an advantage to gain air superiority locally for a limited timeframe, but this even is questionable. A sudden strike, just like the Luftwaffe against frontier airfields would be necessary, but this puts the Brit´s automaticly in a very uncomfortable agressor position.
But it would be very interesting how it could develop.
Moscow was radar guarded from all directions:
(VVS radar stations at Moscow from north to south)
Jaroslav (operating from sept. 1941 on)
Kashin
Wladimir
Klin
Moshaisk
Kaluga
Rjasan
Tula
There is no hole in the zones and the range is pretty good. In 1941 countermesures don´t play a role, they could take into effect in 1943 but moreso in 1944.
But you are right, beside of Moscow, only Odessa had considerable radar coverage. However, if the RAF would shift to night attacks with all it´s shortcomings in precision and naviagtion (keep in mind that the Wellington, Stirling and Warwick have a good range: at least about 4200 Km, that are around 1.800 km striking distance with reduced payload) it could have made it through the defense of other targets, like Smolensk or Kiev. But the effects would be very limited in nighties.
Another question is how soon would the VVS been forced to develop own airborne radar if the RAF stays in the nightibombing. Not in 1941 probably, but it could happen sooner in these szenarios.
The next problem is the avaiability of planes for combat sorties. The RAF would be forced to stay in extremely high sortie numbers (comparable to the peak of the BoB sorties) over the whole timeframe of 1941. I doubt that the RAF could field these operations. they needed 1941 and 1941 to recover from BoB and build up their strategic bomber force. A prolonged service in such a high degree could be far beyond the limits of the RAF.
And all the ground forces depend on help from them, daily. (...I am convinced that the RAF would have developed a special GA plane for this task, comparable to the Il-2, maybe more advanced..)
