Subject: Magic Mossies
Aussiegunneragain    7/11/2010 9:01:10 AM
There was a thread on here a few years ago put up by a fellow named Shooter, who was trying to make the argument that the Dehavilland Mosquito was a strategically insignificant aircraft which should never have been produced for the RAF, because it represented a waste of engines which could have better been used in Avro Lancasters. Shooter, an American, had a hobby of trying to diss any non-American type that had an excellent reputation (the Spitfire was another favourite target) and most people here told him he was being a clown with that being the end of it. However, the thread has stuck in the back of my mind and made me wonder whether in fact the Mossie, despite its widespread usage in a variety of roles, was in fact underutilised in the daylight strategic bombing role? It did perform some very important low level raids such as the daylight raid on the Phillips radio works (along with Ventura's and Bostons - far less Mossies were shot down)in Holland during Operation Oyster. However, I can't find many references to the Mossie being used for the sort of regular high altitude daylight strategic bombing missions that the B-17 and other USAF daylight heavies conducted. Consider its characteristics: -It could carry 4 x 500lb bombs all the way to Berlin which meant that you needed three mossies to carry a slightly larger warload than one B-17 did, which upon this basis meant more engine per lb of bomb in the Mossie. -However, the Mossie was hard to catch and was more survivable than the Heavies. The latter only really became viable with the addition of long-range escort fighters, something that the mossie could have done without. -It only required two crew versus ten on a B-17. Without intending to be critical of the USAF daylight heavies, because they were one of the strategically vital assets in winning WW2, I am wondering whether had the RAF used the Mossie in the role at the expense of night bombing operations in Lancasters? I have read accounts that suggest that the later were not really directly successful in shutting down German production, with the main contribution being that they forced the Germans to provide 24/7 air defence. If they had used Mossies more in the daylight precision role is it possible that the impact that the fighter-escorted USAF bombers had on German production might have been bought forward by a year or so, helping to end the War earlier? Another idea that I have is that if Reich fighter defences had started to get too tough for unescorted Merlin powered Mossies on strategic daylight missions, that they could have built the Griffon or Sabre powered versions that never happenned to keep the speed advantage over the FW-190? Up-engined Fighter versions of the Mossie would also have probably had sufficient performance to provide escort and fighter sweep duties in Germany in order to provide the bombers with even more protection. Thoughts? (PS, in case anybody hasn't worked it out the Mossie is my favourite military aircraft and my second favourite aircraft after the Supermarine S-6B ... so some bias might show through :-). I do think it has to rate as one of the best all round aircraft of all time based on its merits alone).

All true! Thank you for making my point! Total RAF-BC KIAs were the larger figure and included those of the Sterling and the other Heavy Bomber, which name escapes me now. But I figure that it was more like 24,496 just from Lancasters because some of the crew made it out of stricken bombers. On the other hand American Casualties from Heavy Bombers in the ETO never exceeded 26,XXX, that from all types. The rest of America's 52,000 casualties were from Medium Bombers and fighter planes. so 815 medium bombers and the fighter losses equate to 26000ish casualties yet 5500 heavy losses only accounted for 26000?
Well, yes. 5,500 heavies would have had about 55,000 crew onboard when hit and since over 60% of our crews escaped after critical damage to create the 35-40 thousand POWs previously mentioned by you and others, that leaves about 26,000 KIA. So once again, I say yes, it is about 26,000 casualties.
so by your figures we have 26K killed in Heavy bombers, now if we are extream and state that all medium and light bombers carried 10 crew and all of them were lost in the planes loss we have another 8k, now assume another 2k for kia without the loss of the Bomber we than have 36k from 55k that would mean that the USAAF lost 17k fighter pilots
 
Or you could do more research in the archives of the USAF in Daton Ohio. By the way, going back next week if you have any vital matter you want me to look up?
 
No but you have, you need to see that a 4000lb would fit in the b17 bay - neither will more than 2 (1 per side) 2000lbs, and that 34 440lbs couldn't be carried, you need to see that your figures for bombing is wrong, your max weight and max range figures are fiction, hell just about everything you have ever posted you need to revisit and understand why you are wrong, however do I expect any of this, no, as you would never admit that you are wrong

4. From that very paper; They have seven or is it ten different "Average Bomb Load" figures, NONE of which agree with their total bomb loads/sorties calculations!
yet you are certain you are correct, yet all the official sources show that there is no "definitive" number, however they all closely agree that you number is way off
5. The TOTAL number of sorties flown by all types of British Heavy Bombers is only about 12% more than the TOTAL number of sorties flown by B-17s alone! 335K/298K!
as pointed out numerous time, bombing a target like the Ruhr is not the same as a railway yard in France, but it took the US twice as many missions to drop the same weight, despite having what was 4x the number of bombers availiable at the very end, if youi check the mission rate you will see that B17 flew more missions in 45 than it did in 44, in fact they flew more in 45 than it in 43 and 44 combined
 At least according to the report quoted above, and ALL other sources too! That figure alone makes the B-17 the more reliable of the two!
no as the numbers available were at the maximum and the opposition was at its lightest and the targets were softest all these would sway the figures
6. Given all of the above, I re-state my basic claims in this argument;
 
A. For any given load up to any that can be carried inside the B-17, the B-17 will fly farther
(as proved many times the Lancaster could and did fly further with bomb loads that were completely beyond the ability of the B17)
, higher
(a requirement for day not for night operations, so pointless, you cannot state that a requirement specific to one aircraft makes it superior to the other, if you could we could say that the Lancaster was capable of carrying the tallboy - beyond the capability of the B17 so the Lancaster is superior, or even that the Lancaster was catapult capable the B17 not, could the Lancaster have increased celing, yes of course, use the High altitude Merlins and extend the wings by a couple of feet (proven in the later Lancasters/Lincoln)
 and more often than any Merlin engined heavy bomber flown in WW-II.
only because the RAF saw no reason for a > 30k bomber as it was more vulnerable than a night bomber and  by 44 less accurate, so no attempt was made to get this out of a heavy
The only real differance between the two is the typical mission profile.
no the only real difference is the bomb load
B. The B-17 was much tougher plane to knock down than the Lancaster. See losses/missions in the report above.
Not proven, only your misunderstanding of mission profiles would lead you to think this, if you fly risker missions you will suffer higher losses regardless of the survivability of the plane, if you check those daylight missions the Lancaster flew in 44/45 and compare to the B17 on the same type of missions you will find that the Lancaster suffered fewer losses, what can be concluded is that the RAF flew higher risk missions than the USSAF
 
C. The differances in bomb load delivered by the RAF heavies and American heavies was entirely due to the huge differances in mission profile, not Aerodynamic properties of the two planes.
not true, the B17 was incapable of carrying the loads to the ranges needed regardless of any mission profiles
 
If the Lancasters had to climb to altitude and circle over their bases forming up for up to 80-90 minutes before departing toward Germany like their American counter parts, their range would be about 250-320 miles less than the typical B-17 mission and 380-450 miles less than the typical B-24 mission. (The longer the mission, the larger the differance.
But not true, the Lancaster had a longer clean air range then the B17 or the B24 (excluding the ELR B24s) so whilst the difference might be less even if the Lancaster had to form up and fly formation it would still out range the B17s

D. Acording to the report cited above only a little over 40% of all bombs dropped by the RAF landed anywhere near their intended targets, most of those from their ~40,000 day light missions flown late in the war. Even then, the bomb scatter was excessive. See the above report.
yet it was superior to the USAAF efforts
E. The total weight that could have been carried, but was not, is about the same for the Lancaster and B-17G, IE 17,600 pounds and 18,000 pounds, ir-respectively!
but as pointed out that the Lancaster could and did fly with that weight and the B17 maximum war load was < 10000lbs and even that was for short range "special missions" and sub 3000lbs missions were common, you going back to using discredited number
F. While I can recently find no proof, the loads I stipulated COULD have been carried, there is no reason why they could not have been done IF they had chosen to do so!
whilst a 17600lb load could have been possible (but only a few G models with external racks which IIRC was less than 100 aircraft) it was never carried and was limited to a range of 650 miles their and back (including formup) now where near the range the Lancaster managed with 18000lbs and all lancasters could carry that
 The loads are with in respective lifting abilities and the bombs fit dimentionally!
yes they fit, to hit the 17600 you need to carry 2x4000lbs bombs on external racks something that was believed to be possible but was never tried operational and proved to be a bad idea when tried in the safety of the US
G. This late at night, if I have forgotten anything I could have said in the past, please enter it here!
their is a 4000 character limit and no one wants another 100 pages of the rubbish you spout

that does not look impressive for US  bombers does it
 
 
Also

The combined number of heavy bomber sorties mounted by the 8 & 9 USAAF between August 1942 and May 1945 was 332,904 of which 274,921 were classified as "effective". [82%]

In summary, the numbers Shooter quoted repeatedly were carefully selected 'lies', that omitted important ancillary information to put the data in true context.
So, using your numbers, The USAAF flew 332,904 sorties of which 274,921 or ~82% were effective at a cost of about 5,500 heavy bombers of the B-17/24 types? Is that it? Are those the right numbers?
Then there is the total of all RAF-BC sorties over the six years of the war they fought, was about the same number of missions? At least in nice round numbers witn, IIRC about, or less than 3,400 Lancasters lost, out of 156,000 sorties? Approximately?
Is that about right? I mean lets use the correct numbers if we are going to do this right.
 
The number of heavy bombers "lost" by the 8 & 9 AAF
amounted to 5,548, of which 2,452 were shot down by
enemy fighters and 2,439 by anti aircraft fire. 607 bombers
were lost through other causes. 5,324 fighter aircraft
of the 8 & 9 AAF were also lost, but it is not clear whether all
the fighter losses occurred during protection cover on
bombing raids.(Table 159). Because operations were in
daylight and losses were observed by other aircraft these
figures are probably accurate.

But wait! These are about the same as the numbers I pulled from my admittedly faulty brain, so it can not be that bad?

1. I have never stated that these were just lancaster casualties! Ever.
Lie. You used the figure 55,000, and you said Lancasters in the same posts at least four times. 
   
3. Read the entire paper. In it it states many DIFFERENT figures that dispute each other AND which I have never made light of, but have repeatedly stated that I do not care the least of which you use!
4. From that very paper; They have seven or is it ten different "Average Bomb Load" figures, NONE of which agree with their total bomb loads/sorties calculations!
Those are subsets of the same overall numbers manipulated to show different aspects of the same thing such as which bombers carried what percentage of loads, crew survival by sortie, and different bombing periods.   
I was only refering to the list of nine or was it ten, different by both source and number, "Average Bomb Loads" for Lanc's. I still ask, if those numbers, any of them are so good, why do NONE of them agree with the simple math of 608,000 tones dropped over 156,000 sorties equals about 8,000 pounds per sortie?
This is the ONLY question under debate! If they flew ~156,000 missions and dropped 608,000 tons of bombs, THEN what was the average bomb load per mission?
5. The TOTAL number of sorties flown by all types of British Heavy Bombers is only about 12% more than the TOTAL number of sorties flown by B-17s alone! 335K/298K! At least according to the report quoted above, and ALL other sources too! That figure alone makes the B-17 the more reliable of the two!


Incompetent you are. What it means is that a B-17 carried less bombs by weight per sortie Never in dispute! EVER!
Are you that stupid that you do not understand this?
AGAIN, NEVER IN DISPUTE!
   
6. Given all of the above, I re-state my basic claims in this argument;

A. For any given load up to any that can be carried inside the B-17, the B-17 will fly farther, higher and more often than any Merlin engined heavy bomber flown in WW-II. The only real differance between the two is the typical mission profile.
And yet the 
conclusions reached in Part 27 of the study are exactly OPPOSITE to every claim you make.
    Not at all!

 

B. The B-17 was much tougher plane to knock down than the Lancaster. See losses/missions in the report above.
      
Since USAAF B-17 losses plane and crew losses are as great for half the tonnage dropped as Lancasters!
We are not argueing about losses per ton, only losses per sortie!
     


C. The differances in bomb load delivered by the RAF heavies and American heavies was entirely due to the huge differances in mission profile, not Aerodynamic properties of the two planes. If the Lancasters had to climb to altitude and circle over their bases forming up for up to 80-90 minutes before departing toward Germany like their American counter parts, their range would be about 250-320 miles less than the typical B-17 mission and 380-450 miles less than the typical B-24 mission. (The longer the mission, the larger the differance.
Where did it take 90 minutes for a 27 plane group to form up?
It is not just the first 27 planes, it is the twenty to thirty groups of 27 planes each that have to form up on the first group, and yes it some times took that long!   

D. Acording to the report cited above only a little over 40% of all bombs dropped by the RAF landed anywhere near their intended targets.
Before 1944 40% missed within their aim points' CEP circle. After 1944 70 %.  You like to omit facts don't you devious one? 
Does it matter much if it is the 40% I wrote above, or the 70% that missed that you wrote below my statement above! It is still 40-70% Missed and their "Aim Point's Circle was inside the City boundries, not the cross in the scope! The entire city was the aim point and most of the bombs missed! By my figures quoted from the RAF's own SBSU report, or by the number you quote above.

2, it would make the aircraft uncontrolable in pitch      
 Almost certainly resulting in a sudden pitch up, followed by a stall, or PIO= Pilot Induced Occilation resulting in ecessive loads beyond the aircraft's stress limits! With the CoG range AFT exceeded by more than one foot, or almost two feet, depending on who's guess you favor.    

If it was the second that would require both a bomb hang up AND pilot error,

Not at all. PIO is a condition caused by factors normally beyond the controll of the pilot, when the plane's CoG is so far behind the desired range!


so basically you are saying that they lost hundreds of planes to PIO? you seriously expecting this to hold water? that all these loses were down to a CONTROLLABLE situation?
Once again. Aft CoG excursion is not something that any pilot can control. When it happens the loss of control is both quick and beyond the pilot's ability to control.
Now that is rubbish, it would take longer than that to transit between one sudden climb and one sudden dive, and PIO would need sustained porposing to cause failure
However long it takes, how does that change the outcome?

But in any case the crew who are being tossed about by the sudden violent vertical positive and negitive G maneuvers can do nothing to escape when they are alternately flung from floor to ceiling! 

and not even the sudden disintegration of the plane there were never any survivors, yet in less losses due to flak(according to you) there were many reports of survivors from aircraft explosively disintegrating   
Point to any post where I stated any of the above sentance! You are "Inferring" things I never said because of your lack of knowledge about how and why aircraft do the things they do!

but his basic oppinion was that the whole idea was rubbish, whilst a CoG change of this order was not nice it certainly wouldnt have moved the plane out of control flight parameters.

OK, fine. That is his oppinion. Exactly how much aft CoG excursion does he think it would take to make the average Lancaster un-flyable?
 

No, I got the CoG "Ideal point" from a post by others and the CoG range from someone elses post.
well you never credited it you claimed it was YOUR idea!
Again, that is simply not true! I always atributed the sources, just like I did above. The problem is the other people making assumptions about what I wrote WO actually understanding it or taking the wrong point from it.

I use those Datums because they are larger than I would have expected, but are still exceeded by a hung 1,000 pound bomb in the last row aft!
only according to you no one else, in fact every one else thinks that this is a load of made up rubbish, it was when you tried the same question on a professional pilots site?
Please post a link to that prossessional Pilot's web site, so that I might review the data that is being used against me?
   
Also note that I am prepaired to argue the whole point again, should any one post copies of the realivant documents! 
Their are no relevant documents, Actually, there are realivant documents. They are the Lancaster's pilot's Manual where they list the CoG Datum and the Permissible range of CoG values! They have been posted several times over the length of this argument. Either look them up in the thread, or the various online copies of the manuals. If you are so convinced you find a document that states that such a loading at such a distance from the CoG would cause potentially fatal change in the flight envelope!
I never looked because I knew the results of such an excusion. But several other in this debate have looked and posted links to same. But their either thought it said something else, or failed to not the significance of scertain PPs in those links, like the PP and Graph of how a PIO happens and the result of same. (Which I pointed out in my next reply and they all ignorred.)

yet you are certain you are correct, yet all the official sources show that there is no "definitive" number, however they all closely agree that you number is way off
YES! I am absolutely certain that 608KT divided by 156KSorties is under 4 tons per sortie! You do the math and proove me wrong! AND, those are official RAF-BC numbers!
5. The TOTAL number of sorties flown by all types of British Heavy Bombers is only about 12% more than the TOTAL number of sorties flown by B-17s alone! 335K/298K!

6. Given all of the above, I re-state my basic claims in this argument;

A. For any given load up to any that can be carried inside the B-17, the B-17 will fly farther
(as proved many times the Lancaster could and did fly further with bomb loads that were completely beyond the ability of the B17)
As has been stated even MORE times, only because they flew vastly different mission profiles in the dark when the bad guys could not deefend themselves as well.
could the Lancaster have increased celing, yes of course, use the High altitude Merlins and extend the wings by a couple of feet (proven in the later Lancasters/Lincoln)
YES! That is right! But the Lincoln's ceiling is still many thousands of feet lower than a B-17 from the war and the Lincoln never flew a WW-II operational sortie! Never!

 
The only real differance between the two is the typical mission profile.
no the only real difference is the bomb load
But bomb load changes with mission profile! I agree the Lanc TYPICALLY carried more bombs, but it flew mission profiles that would have been suicide in broad day light! ALL I state is that if the rolls were reverced and the Lancaster was required to fly in broad day light in formation of 1,000 planes at altitudes of over 24,000', it would have carried fewer bombs to a shorter range than the B-17, AND that if the B-17 had flown the Lanc's missions at night from lower altitude with out burning gas to form up, it could have carried more bombs farther than the Lancaster with fewer casualties!

  
C. The differances in bomb load delivered by the RAF heavies and American heavies was entirely due to the huge differances in mission profile, not Aerodynamic properties of the two planes.
not true, the B17 was incapable of carrying the loads to the ranges needed regardless of any mission profiles
No, this is where you make the mistake of conflating comparisons. It is the Lancaster that can not carry the same loads as far, IF it has to burn the gas to climb to altitude over England, burn more gas to form up into large formations and fly at those hights and RTB with the same "Reserve" of gas on board as the B-17 IN BROAD DAYLIGHT! Regardless of how many or what size of bombs fit into the Lanc's bomb bay, some must be left behind if it is to fly at those altitudes and more must be left behind if it is to form up over England and RTB with 45 minutes worth of gas in the tanks! It is that which is the ENTIRE POINT!

 

If the Lancasters had to climb to altitude and circle over their bases forming up for up to 80-90 minutes before departing toward Germany like their American counter parts, their range would be about 250-320 miles less than the typical B-17 mission and 380-450 miles less than the typical B-24 mission. (The longer the mission, the larger the differance.
But not true, the Lancaster had a longer clean air range then the B17 or the B24 (excluding the ELR B24s) so whilst the difference might be less even if the Lancaster had to form up and fly formation it would still out range the B17s
  If this last was true, then why do ALL the books and Wiki state the opposite?

No, not at all, until you understand one set of number were for the easy, at least according to the RAF-BCnight missions at low altitude and the other number was for daylight missions at high altitude?
 
Also
Lancaster bombload for 1500 mile range - 11500lbs
I have never disputed this! Ever. Just tried to inform you how those numbers were arrived at. Take off, climb/cruise, gaining altitude on the way to the target, WO formation, fly 750 miles, drop the bombs, RTB 750 miles, land with no reserves or gas in the tanks, all at night in the absence of true opposition.
Now, why don't you calculate the numbers, IF, it had to fly the same mission as the B-17s in broad day light? RIGHT!

You misquote and misuse the numbers, one called Shooter.

You've only proven that you lie again because you use my numbers which are NOT your numbers that you originally used, (See your first posts.)

Additionally you write that B-17 losse were seen in daylight,which is obvious and a foolish statement (though you lie about those ratios since it was fighters/flak equal)  ignoring that you originally claimed most Lancasters were lost to flak, when you were warned that the British knew their losses were 2/1 fighters/flak.

The only consistent is that you are wrong, one called Shooter and we now know you write falsely.
