We do try to compare RAF vs. VVS, not commonwealth.
If operating from Poland, Moscow would be in range for nightattacks with Lancaster at reduced payload. NOT EVEN ONE OF THE MAJOR AIRCRAFT COMPLEXES IS IN RANGE OF A LANCASTER ATTACK. Just take a map and find complex 43 south of Nishnewartowsk, which is the closest major plant to Poland, we are talking about a distance of 7.450 Km if you want to come back ( 4.720 miles). Even a Lancaster MK-II had only a range of 2.510 miles total. What a payload could a Lancaster carry on these distances?
You may argue that Moscow (closest 1250 miles) and Gorki (closest 1800 miles) are reasonable targets (Moscow because bomber Harris would take this as a priority target and Gorki because it´s powerplants produce a majority of electrical energy for the european part of the SU), but there is still no impact on the production field. And some big planes flying at Il-2 speed for 5 hours over enemy held terretory would exclude day sorties.
No Mossie or any other RAF escort fighter could accompany them on these distances. There is also a dense AA defense over Moscow, Radar aided and excellent ground controll for the interceptors (which did succesful night interceptions particularly in late 1941).
I wonder what could bring the RAF air superiority in the front affairs since the VVS was able to fly in average two-three times more combat sorties. And on the ground, the british forces would have been crushed as well by the red army forces, leaving Poland and Germany for the VVS.
The only way to bring RAF on equal or better terms is with the help of the US and at the end of ww2.
The VVS also could field much more planes, leaving the RAF over Poland in the defensive.
One example to the quality lack of the VVS (earlier years):
The MiG-3 in 1941 was superior to anything the british (and germans) had in high altitude, there it was 100 Km/h faster than the Bf-109 F-2 and 125 Km/h faster than the Bf-109 E-4.
And another one for the late timeframe (44):
I-220 (A) -proposed designation: MiG-7, top speed: 697 Km/h (433 mp/h) at 7.000 m (23.230 ft), range: 400 miles, time to 5.000 m: 4,6 min., service sailing: 44.820 ft.)
weapons: 4 Shvak 20mm gunsTwo prototypes build in 1943, tested in early 1944 originally as an answer to the german Bomber-B program (serial production canceled because of the german program, which also was canceled: no need, no plane.
For the Kriegsmariene: German submarines succesfully sank british ship in the firth of forth at may, 5th. 1945, a mock attack of U-2511 on a british task force would have resulted in the sinking of a british heavy cruiser. The attack was that fast and stealthy that the british simply doesn´t believed Schnee in the first moment, afterwards, as they compared the time and position figures, they found out that he evades 7 destroyers in this convoi with ease...
The evacuation was the most succesful surface operation of ww2, Prinz Eugen, Scheer, Lutzow and Hipper repeatedly drove off russian tank forces by shore bombardments, One of these cruiser was destroyed by Lancaster Tallboy bombs, another by VVS pilots.
