Losses Luftwaffe day fighters according to Christer Bergström: 16.100 (total loss = > 60% damage) with 8.500 pilots killed.
Losses Night fighters and other aircraft (bombers, transports, ground-attackers and recce): Anybody knows???
They (the Luftwaffe day fighter arm) claim 70.000 kills (25.000 West and 45.000 East). Of these 10-15% can be subtracted to double claims, so it may be 60.000 in total.
The nightfighter arm of the Luftwaffe claims a further 5.750 aircraft (most heavy bombers and mosquito's) with possible 5000 kills in reality.
Soviet losses were in reality only 1,4% of the 3.500.000 sorties flown or about 46.100 aircraft (not including aircraft destroyed on the ground).
These claims are nowadays further proved by Finnish and Russian sources.
The FLAK claims 20.000 aircraft destroyed.
The bomber and recce arm claims are unknown, but the surely also shot down enemy aircraft.
Note1. of all claims only the total losses are interesting to know, because a claim does not necessarely lead automatically to 1 kill.
Note2. not included are all Allied aircraft destroyed on the ground, lost by accidents or landing in Switserland (3.500 at the end of the war).
These are substantial numbers too.
