You will maybe need a Russian translator, but the website
http://allaces.ru/p/epismain.php will list hundreds of episode of the air war on the Eastern front, classed per month and day. So you may find interesting things for 1945.
As for the content, there is a mix of articles coming right from Soviet era, personnal testimonies and more recent articles using open archives. The main difference between the latter and the first being their focus on Soviet losses and possible failures rather than huge enemy losses and repeated heroic deeds by Soviet airmen.
Anyway, if you ever keep a critic eye, this website may be interesting for you.
