"On the 10th of August he lists 805 servicable 109's, the WHOLE of FC mounting 708-764 servicable aircraft in the same period on a daily basis."


660-680 is the number of servicable Spitfires and Hurricanes available according to the RAF.  Using your numbers for Luftwaffe fighters of 805, we see a ratio of 1:1.18 or 1:21.

Those Spitfires and Hurricanes were available for battle according to the RAF.

Hardly the gross exaggeration of 2:1 for RAF first line fighter to 109's.

You seem to want to claim that the Luftwaffe was flying in massive formations of 109's.  It was not.  The most common task early in the battle for the Luftwaffe 109's was "Frei Jagd" missions or fighter sweeps.  The majority of the Luftwaffe fighters were engaged in this task.

These the RAF correctly ignored to target the bomber formations.

Unlike the Allied fighter sweeps of 1944, the Luftwaffe fighters did not have Radar Ground Control at this time.  This meant the RAF could avoid them with radar ground control instructions  

The Luftwaffe fighters on the other hand were not vectored to the combat area unless they got good navigational information from the unit in contact over the radio.  Then they had to have the navigational skills to find the moving combat engagement.

So the operational details are not as simple as they are being made out.  They certainly do not support the contention that the RAF was grossly outnumbered in single engine fighters.  On some engagements sure, on many however they were even or had advantage due to the force multiplier of radar.

All the best,

Crumpp

Oh, come on Crumpp, - you're still missing it.
"Those Spitfires and Hurricanes were available for battle according to the RAF.

Yes they were available. Actually counted with Blenheims, Defiants and Gladiators they mount to some 700+ or so.

But they cover the whole of Britain while the 109's are just on the south east corner, that is in this case, the point. Only a part of the Hurris and Spits were indeed fighting  many times their number. In the ring!

BTW, some raids had some 3 fighters for each bomber. Escort. The 109's were quite tied up with the bombers, although there was also the "freie jagd" which was quite more successful. The 109's, being that many were not all close and at the same alt, - but also stacked higher. I pretty much guess that Göring's subordinates, which included probably the most brilliant minds of WW2 air warfare, did their best to compensate for his spontanic, and at times, passionate, decisions.
It was very interesting to carry out the flight trials at Rechlin with the Spitfire and the Hurricane. Both types are very simple to fly compared to our aircraft, and childishly easy to take-off and land. (Werner Mölders)

No not really....

From Milo's Alex!

304 - Spitfires

384 - Hurricanes

= 688 total RAF first line fighters

The RAF had 1,200 planes on the eve of the battle which included 800 Spitfires and Hurricanes - but only 660 of these were serviceable. The rate of British plane production was good - the only weakness of the RAF was the fact that they lacked sufficient trained and experienced pilots.


http://www.historylearningsite.co.uk/battleofbritain.htm

These sites very much agree with the RAF's number:
 
Quote
By the beginning of July 1940, the RAF had built up its strength to 640 fighters,



Quote
The 109's were quite tied up with the bombers, although there was also the "freie jagd" which was quite more successful.


Fighter Sweeps are generally flown in support of a larger objective or mission.    These sweeps would be timed or proceed a raid.  These sweeps are performed outside of visual range of the main raid body.  This caused Goering to change to a close visual escort that robbed the 109's of the initiative.

However lacking radar ground control meant the Stafflekaptain's were limited to visual range.   So while they could engage on better terms if they encountered the enemy, it was more difficult to mass forces.

The RAF simply avoided the Fighter Sweeps through the use of radar ground control and attacked the main body of bombers.

The Luftwaffe Fighters had no control after take off and flew much of the battle under radio silence.  Granted their radio discpline was considered poor.

Good book to learn about actual Luftwaffe tactics used in the BoB is:

http://www.amazon.com/exec/obidos/ASIN/1853673277/tailslidesaircom/103-5865364-1525459

I can scan the page showing a typical operational day in the BoB and show you exactly the Luftwaffe's doctrine.  

You will find that the assumption of large numerical superiority of the Luftwaffe fighters disappears and the ratios are similar.

Quote
BTW, some raids had some 3 fighters for each bomber.


That would be very surprising.  Luftwaffe doctrine called for a 1:1 ratio of fighters to bombers between the close escort and the escort cover provided enough fighters were available.

All the best,

Crumpp

Forget it Angus, it is wasted effort. He 'talks the talk' but does not have a clue.

Have to love those 'copy and paste' sites he uses as reference sources.

Crumpp can't get into his noggin that all those 600-700 Spits and Hurries that RAC FC had available were not all based in the south while Luftlotte 2 and 3 with their ~800 fighters were based only a few miles across the Kanal from south-east England.

He still is caught up in total numbers, which has nothing to do with 11 Group.

Still waiting for how those fighters from the north of 13 Group participated in the air battles in southern England.

He also forgets that the battle started with Free Hunts but after complaints by the bombers, after being mauled, the fighters were tied to the bombers.

Glad you know what a dictionary is Crumpp. Now go check on the word 'used' which is the word you said.

Quote
According to the RAF and the sources you posted, the number of fighters the RAF used was around 660.
I might have $1000  available in the bank on the first of the month, but that does not mean I used all that $1000.

BTW Crumpp, I don't know this Alex, so why do you keep saying what you do? Hit a nerve that I had better sources than your generalizing Wikipedia?

Your description applies to the latest phase of the BoB, - when the LW is attacking London in daylight and finally the controllers had enough time to vector some proper force (including 12th group) to altitude and into a good interception position.
But the first phases of the BoB were at the south coast, - first the convoys, then the radar sites then the airfields of FC. That left FC with very little time and as many have pointed out, - including those big wing theorists at the time, - the FC was responding to amazingly well supported raids with "penny pockets" of fighters. I can go and dig up some data on this but really, - sometimes a dozen or so of RAF fighters attacked a force with really heavy escorts, - many times their number. And there were long and hard dogfights about.
But once that the humble 50 miles or so from the coast to London had to be added, the LW was screwed. It gave RAF the time it needed to gather a bigger force - as said in the beginning.


Hi,

yes, in the early phase the RAF got in trouble and the HQ was up to  regroupe the fighters more backward, but then Mr.Goering decided to attack London.
But even in the early phase they never made real massattacks to one airbase.  They always attacked different airbases and other groundtargets at same time, in this way the german forces got splitted up.  Rommel would have attacked one base with all forces and then the next, same like the USAAF most made it over germany. This would have given the LW its advantage in numbers, but the LW HQ was used to the tactical airwar, not to strategical airwar, therfor they used the wrong tactics.

The Bf109E was even on the south side of England badly handycaped by the missing droptank, specialy while escortflights.
Climbing to 5-6000m and meeting the bombers already grapped much of the range. Therefor the bombers often had to fly a direct course to target.
And much more important, the Bf109´s often wasnt able to follow the british fighters to their bases, after they disengaged. This was the big advantage of the P51 in 1944, they could follow the 190´s, 109´s and 262´s.
That the performence of the 109(next to the range) dont was a problem the results in Africa show, where a droptank was available in the 109E4b and E7b, and even here, same like in russia, the german fighter bases always was very close to the frontline.

As far as i know the Radar was available from the beginning of BoB. They already could see the german bombers forming up, so they was able to let the fighters on the ground until they was needed. Without radar they would have needed a patroul system, this would have minimized the power, or they wouldnt have been able to intercept the bombers with a altitude advantage and for sure not before they reached the targets in the south.

The losses of the 109´s also was relative high, cause they fought over enemy area. If a Spit or Hurri got light damaged, they often could land, but how many light damaged or fuelless 109´s sunk in the channel?

Even in best circumstances the 109E had only 30min in combat area(britsh coast to London),  while 'Freie Jagd' in more low level it particular maybe was a bit more, thats still not much, nevertheless in this system the 109E was successfull(same like the P51).

Imho, low range of the main german fighter, wrong tactic for the 110 from the beginning, tactical instead of strategical bomber tactics, the Radar and the agressivity of the british pilots caused the result of BoB.

Greetings, knegel

Your "sources" agree with Wikpedia, The RAF, and The Learning Site.  They all say the same thing Milo.  The RAF had available and used 660-680 first line fighters.  

I have quoted your site, Milo, because you seem to attach value to it.  It says the same as all the others.  


Quote

You seem to be believe that only 11 Group fought the BoB.  Not according to the RAF, Milo.

11 Group's area was the main combat zone but other Groups reinforced them according to the RAF.

Exactly.  

Radar ground control was a huge leap forward for air combat.  It allowed the RAF to move their fighters through these scattered German formations and attack surgically.

Quote

Sure, later in the battle after the numbers were changing to the RAF favour.

And you see this as a good move for the Luftwaffe fighters?

All the best,

I have already stated that 10 and 12 Groups provided some support for 11 Group. 11 Group was the major combattant force.

It is not my site but a site, with more detail, I provided a link to, so is better than the general sites you provided. Available and used are not the same. Still waiting for you to tell us how those fighters from 13 Group, especially those in the north of the Group area, participated in the air battles over southern England.

Quote

No Crumpp. This was before the battle was turning to the British favour.

You do have your problems Crumpp.

As to odds, on July 24. III./JG26, with 3 staffels, escorted 2 staffels of Do-17s over the Thames estuary. 54 Sqd was ordered to intercept. (3:1 fighter ratio) 610 was ordered to patrol Dover to intercept the returning LW a/c. 610 met JG52 (note, no Gruppen number given) which was coming to support the returning Germans. (up to12:1)

Aug 10, 610 again was sent against a larger german force > II./JG52. (3:1)

Aug 31, every available 109 was sent to the Pas de Calais. 1300 sorties were flown to protect 150 bombers.

Sept 1, Kesselring insists that formations be ~75% fighters.

OBW, the Germans had a Freya radar at Wissant, across from Dover. This was used on Aug 8 to direct LW a/c to convoy CW9.

The Germans were actually, at the time of the BoB ahead of the British in Radar technology. However the Brits excelled in the applicaton. During the BoB the LW never got anywhere near the RAF in using radar in a clever manner.
Anyway:
"Radar ground control was a huge leap forward for air combat. It allowed the RAF to move their fighters through these scattered German formations and attack surgically."

The attacks were anything but surgical. However, they were no more chaotic. Surgical accuracy occured at times, when the LW started hitting London. Yet again, see how much the DISTANCE on cruise will do.

I just dived into "Full Circle" which is Johnny Johnsson's book of air combat. He really confirmes that the RAF was, in the beginning, attacking the LW in "penny packets". Sometimes the RAF was still on the climb and outnumbered by 109's.
When the LW losses however became uncomfortable, Göring listened to the bomber pilots, and tied up the escort as close.
That's not the whole story though, because tactics were changed again, and eventually the escort-bomber ratio was 3 to 1, - 3 wings of escort for one of bombers, escorts providing sweeps, high escort and level escort.
This is actually a much favourable setup than the USAAF had to face over Europe some years later! Even regarding fighter vs fighter numbers. And the LW had CANNONS at the time as well as the DISTANCE to cover was multiple.
Told you, the BoB gets more and more interesting the more you look into it.

Oh, and Crumpp: look at this point from Milo:
"all those 600-700 Spits and Hurries that RAC FC had available were not all based in the south while Luftlotte 2 and 3 with their ~800 fighters were based only a few miles across the Kanal from south-east England."

Those include Blenheims, Defiants, and Gladiators, - so Milo's numbers are actually too high, unless it would be referring to the latest stages of the BoB. That's what I listed before in this thread, - go and browse, and see.

There are more statements there quite wrong, just won't pick at them now. The main issue weights more.

You can point to exceptions all day long.  It is the number of "good" days and "bad" days that become critical in a war of attrition.

The total strength of III/JG26 was around 40 aircraft.  This number is spread out amoung the close escort and the excort cover.  No 65 squadron also participated in that action and the Ground controller timed their entry perfectly.  Oblt. Werner Bartels was shot down by a No. 65 squadron spitfire.  Claims and losses were even.

Pure speculation on your part, but I see your a given to that.  Try including all the units next time.

Plenty of Luftwaffe pilots will confirm otherwise.

In fact II/JG26 turned back from Milo's example Mission because their GruppenKomanduer spotted "30 Spitfires" above him!!

Nice of you to do an edit job Crumpp. Even if was only one Gruppen of JG52, on which upon further searching was I. Gruppen of JG52, it was still 3:1.

I see you read real well. It was III./JG26, lead by Galland, not II./JG26. We all know how reliable pilot observations are. That is a new one with a RAF fighter squadron having 30 a/c, especially as there was only #65 and #54 in the area. Why did not those 30 a/c not attack? The RAF was not knowing for laying back.

There was 2 raids that morning, one at 8am and one at 11am. It is the later one I provided info on.

Deighton does mention #65, but they attacked the unescorted Dorniers because the 109s were returning as they were running low on fuel. Take your whining up with him.

Nice of you to ignore this: Sept 1, Kesselring insists that formations be ~75% fighters.

Didn't your example occur in July?  Do you think the reason Kesselring had to issue that order was because formations were going out with less than the 1:1 ratio Luftwaffe doctrine required?

I would say his information is not complete.

III/JG26 had around 25 fighters on strength.  The Jagdgruppen usually ran at 50%-60% of authorized strength.







Looks to me like Luftflotte 2 had a couple of hundred fighters vs 11 Group couple of hundred fighters.  The Luftwaffe hardly had a huge numerical superiority in the BoB for first line fighters.  

All the best,

Crumpp
