Are you saying 5 missions a day is impossible?
For very small numbers of aircraft, for very short period, on very short missions, it's possible. For large numbers, no.
No, that's still not the reason why the Germans shot down twice as many fighters as the British did. What's the difference in dogfighting over Britain or dogfighting over France? I see three differences: fighting time, AA ground fire and pilots being captured when shot down.
The biggest difference is what you do when you don't have advantage. I read recently of a British squadron sent to intercept a German raid during the BoB. There were over 100 bombers, and over 100 fighters escorting them, and 9 British fighters. They were also below the Germans.
3 fighters were climbed to engage the German fighters, the other 6 climbed to engage the bombers.
The reason for semi-suicidal actions like that is the British had to defend against the German raids. In France in 1941 and 1942, the Germans didn't have to defend. If they couldn't attack with advantage, they didn't attack at all.
But as I said, the bulk of the Luftwaffe would have been called back from the Ostfront and have confronted the RAF. As the Germans shot down twice as many as they lost,
Whilst the British were carrying out fighter sweeps over France. That's likely to be one of the first things that changes if the Germans bring the rest of the Luftwaffe back to France.
and they only had 250 fighters in France,
They didn't. Hooton in Eagle in Flames gives the German day fighter force in Western Europe as a low of 430 in Sept 41, rising steadily to 636 by the end of 1942. There were 564 in mid 1942.
Hooton also gives sortie figures. For the second half of 1941, Fighter Command flew 20,495 offensive day fighter sorties, the Luftwaffe scrambled 16,150 day fighters in response.
I'm not going to state that the British would have lost 5 times more fighters but I don't see how one can disagree that British losses would have been much higher.
Only they had that many fighters in July 1940, and still lost. And Fighter Command had expanded greatly since the BoB.
Now you make it sound as if 3,000 aircraft were trying to sink ships over a month. Their primary mission was not to sink ships and how many of those aircraft were bombers capable of sinking ships?
And again, they weren't trained in anti-shipping.
Exactly the same will be true in 1942.
It seems you make the BoB the standard for all Luftwaffe operations. The BoB was going to last for a longer period.If the Germans were planning on keeping up the offensive, they couldn't fly too many sorties.
The BoB was planned to destroy the RAF in a matter of days (5, iirc).
German bombers could fly up to 5 short-range missions a day. That's perhaps not your reality but unfortunately it's historical reality. I suggest you read up on Luftwaffe operations on the Eastern Front.
Maximum effort is not the same as average effort. Hooton quotes a British study on Luftwaffe efforts on the eastern front. The Luftwaffe rarely had more than 2500 aircraft in Russia between June and October, but averaged 1,200 sorties a day. Sometimes as many as 2000 sorties were flown per day.
Stuka units sometimes averaged 75% sortie rate (ie 75 sorties per day per 100 aircraft available), fighter units 60% and bomber units 40 - 45%.
Now if you want to argue a couple of units might manage several missions a day, you'd be correct, but that's not the case for large numbers of units.
If you take those figures and apply they to the BoB in 1942, the Germans with a force of 1500 bombers and dive bombers could make about 900 sorties a day, but that doesn't take into account the availability of escorts.
I see Rommel winning in El Alamein and taking Alexandria and the Suez Channel.
The problem for Rommel is he didn't pay enough attention to logistics.
At El Alamein, Rommel is about 900 miles by road from his main port, Tripoli. All supplies have to be brought by road. A typical 3 ton truck could carry 3 tons, but went about 8 miles to the gallon. That means the 1800 mile round trip required about 225 gallons of fuel, which weighs just over a ton.
That means 1 truck can transport at most 2 tons to the front, without counting it's own spare parts, water, oil etc.
There were two closer ports, Benghazi and Tobruk, but both had very low capacity, and couldn't handle many supplies.
Van Creveld goes into this in some detail in Supplying War. His conclusion is that a German advance into Egypt was an impossibility because of the North African infrastructure:
Given that the Wehrmacht was only partly motorized and unsupported by a really strong motor industry; that the political situation necessitated the carrying of much useless Italian ballast; that the capacity of the Libyan ports was so small, the distances to be mastered so vast; it seems clear that, for all Rommel's tactical brilliance, the problem of supplying an Axis force for an advance into the Middle East was insoluble. Under these circumstances, Hitler's original decision to send a force to defend a limited area in North Africa was correct. Rommel's repeated defiance of his orders and attempts to advance beyond a reasonable distance from his bases, however, was mistaken and should never have been tolerated.
You don't get it. The Germans had fighter aircraft in Greece. As the British didn't have fighters, these fighters were unopposed. If the British did have fighters, it wouldn't mean things would have been different: the Germans could have protected their bombers.
Look at the record of Stuka operations against Britain, which were well escorted, but still suffered horrendous losses. And with air cover, bombing accuracy tends to go down, because the bombers are more worried about protecting themselves than hitting the target.
