@ Trevally:
Thanks to Vlad I was able to locate a couple of atlases of WWII-era Soviet airfields in Google Earth format.
The first one is relative to Finnish and Soviet airfields used during the winter and continuation wars (Baltic and Barents sea areas). Dowload link:

(after installing Google Earth, double click on the kmz file to see arfields' locations and names on the world map; yellow icons = Finnish, red icons = Soviet).
The second project is much more complete, as it includes most of the know Soviet airfiled, as well as a good number of other European and Asian airfields used by various WWII belligerents. Each nation is denoted by its flag. Most airfields got notes (mostly in Russian

, some in English). Download links:

(copy the 'icons' folder from the first link into the Google Earth's installation folder, and double click on the kmz file from the second link).
At this point I believe we have more Russian airfield locations than we need
Still to do: connecting the aircraft I have listed yesterday to the airfields that they historically were based in.
