Denes' post was interesting.
Here are the
Il-2 loss statistics, as found in Hans Seidl's book on VVS aces:
--------------------------------------------------------------------
Year--Total Losses--Losses to enemy action--% of strength at hand
--------------------------------------------------------------------
1941--1,100--600--73.3
1942--2,600--1,800--34.2
1943--7,200--3,900--45.0
1944--8,900--4,100--46.6
1945--3,800--2,000--27.3
----------------------------------------------------------------------
Total: 23,600--12,400--70.3

2. During this period, a constant 75-78% of the day fighters were based in the West. The turnover was enormous: 14,720 aircraft were "lost", while operational strength averaged 1364.
3. During this period, 2294 day fighters were "lost" in the East; the ratio of western "losses" to eastern "losses" was thus 14,720/2294 = 6.4 to one.
4. During this period, a constant 43-46% of all of the Luftwaffe's operational aircraft were based in the East. It should be noted that these included entire categories (for example, battlefield recce, battle planes, dive bombers) that were used exclusively in the East, because they couldn't survive in the West..
5. During this period, a total of 8600 operational aircraft were "lost" in the East, while 27,060 were "lost" in the West; the ratio of western "losses" to eastern "losses" was thus 27,060/8600 = 3.41 to one.

ra, someone has an agenda, comparing
all Soviet Air Force to
only the 8th AF heavy bomber losses.
"
In 1945, the Soviet Air Force had an average loss rate of 0.6 %, while the 8th AF heavy bombers had an average loss rate of 1.15 %.
These relations are even more remarkable in view of the fact that the Soviet most of the time were faced with a stronger - or vastly stronger - German fighter opposition than the Western Allies were. The elite of the Luftwaffe always was concentrated against the Soviets, and the Allies were quite fortunate to be spared a confrontation with the best of the Luftwaffe."
USAAF stats can be found here,

http://www.ww2.dk/ A complete listing of LW units in the West for the time period (1944) would be useful.
