Subject: Modify the B-17 into night bomber/low altatude streak bomber?
45-Shooter    2/14/2013 3:55:59 PM
Given the multiple lines of debate; B-17 Vs Lancaster Vs Mossy, I post the following question; To convert the B-17 from a day bomber into a night/streak bomber, remove the top, bottom and chin turrets, remove the waist and cheek guns and gunners, relocate the flight deck to just behind the bombadier's space so that there is onlythree or four crew! Install large spinners on the props and install a single 20 mm auto-cannon on a flexible "X" bow mount in the plexi nose. Reduction in frontal area, weight and increases in streamlinning make flight both much faster and much more efficient! Since there is room for four 4,000 pound MC bombs in the bomb bay, the shakles should be modified to hold those four heavy bombs if the larger shakle does not fit now. Otherwise eight 2,000 pound bombs should be the standard load. Given the 210-220 knot cruising speed of the Mossy required to make the placard range, the new faster B-17N/S should offer more of everything that makes the Mossy so neat?

Wrong i wrong. A=A. Putting a lampshade over it and lying about it calling it right, does no good. It makes you look stupid.
See the cover photo of the F-4D on the book, IIRC, Killer Rays where the gun muzzles are plated over on both wings and the weapon of choice is the Sidewinders hung underneath! If they never used the guns and got rid of them before most other planes had guided missiles how significant are they.
How significant was the Attacker? So that is 1-1/2 out of how many dozens of other combat planes after WW-II? Right!

At this point, I will let the Shooter drivel nonsense and let rational minds judge.

45-Shooter    Returning to the original argument;   7/16/2013 1:20:22 AM

At this point, I will let the Shooter drivel nonsense and let rational minds judge.   
1. The B-17 was faster on less power than the Lancaster! A simple statement of fact.
2. The two planes had late war MTOs that were equal to 72,000 pounds.
3. the EEW of the B-17 was a few hundred pounds less than the Lancaster.

1, the B17 never carries more than 9200lbs on combat missions
2, the B17 never carried more than 4000lbs to long range targets
3, the B17 could not carry bombs beigger than 2000lbs internally
4, the B17 could not carry more than 2x 2000lbs internally
5, the Lancaster carried more bombs further than the B17 was capable of
6, the Lancaster carried larger bombs than could be carried by a B17

Not relevant!
 
2, the B17 never carried more than 4000lbs to long range targets

3, the B17 could not carry bombs beigger than 2000lbs internally
Not true!
 
4, the B17 could not carry more than 2x 2000lbs internally
Not true.
 
5, the Lancaster carried more bombs further than the B17 was capable of
Not true! Since the B-17 carried about 1/3rd more gas than the Lancaster, and was more efficient aerodynamically, it could fly about 40-50% farther than the Lancaster at any given weight and altitude.
 
6, the Lancaster carried larger bombs than could be carried by a B17
As far as I know, no Lancaster mission ever carried any 2000 pound MC bombs. Although I freely admit that it could have done so if they replaced the 4,000 "Cookie" or replaced all five or six of the CL bomb shackles with three 2000 pound types evenly spaced down the length of the bomb bay, to carry three 2000 pound bombs.
 
 

Your entire point of all of the sub points above is proof that they chose to do those things at the expense of doing other things! Those were "Strategic" choices made for Strategic reasons! If the Lancaster had been required to fly in broad day light at higher altitudes to avoid flack while carrying more armor and weapons, the weight of those items would have subtracted from the bomb load. Then they would have been forced to increase fuel storage which would have forced a smaller bomb load. The addition of more weapons would have caused more drag and further reduced the range and bomb load. And finally, if required to form up into large masses of planes flying in formation, their range would have been reduced even further.
There is no magic here from either plane, B-17, or Lancaster. The rules of aerodynamics are immutable. The B-17 was faster on less power and thus more aerodynamic than the Lancaster. It was a more refined design that was stronger, but Massed less as proven by their Empty Equipped and Maximum Take Off Weights and reputations for toughness on one hand and frailty on the other.

Why bring up the 2,000 lb MC bomb specifically Shooter? Curious.
 
I can find plenty of evidence for Lancasters dropping the 2,000 lb HC and 2,000 lb AP bombs (typically six of each), but very little for the 2,000 lb MC. Perhaps because the 2000 MC bomb was very little used by the RAF during the war? 
 
From "Bombs Gone", the total numbers of each type dropped by Bomber Command:

22,000 lb MC 'Grand Slam' = 41
12,000 lb MC 'Tallboy' = 854
12,000 lb HC = 193
8,000 lb HC 'Super Cookie' = 1,088
4,000 lb HC 'Cookie' = 68,000
4,000 lb MC = 21,000
4,000 lb GP = 217
2,000 lb HC = 28,633
2,000 lb AP = <10,000
1,900 lb GP = 2,141
1,000 lb GP = 82,164
1,000 lb MC = 253,800
500 lb GP = 531,334
500 lb MC = 403,000
250 lb GP = 149,656
250 lb incendiary = 7,000
40 lb GP = 42,939
30 lb Phosphorus = 3,000,000
30 lb 'J' incendiary = 413,000
4 lb incendiary = 80,000,000

12,000 lb MC 'Tallboy' = 854
These two came as a complete surprise to me! I had no idea that the ~30 or so Lancaster Specials flew that many missions.
12,000 lb HC = 193
This too!

45-Shooter    For some reason, it's cutting off the top of my post!   7/17/2013 12:27:02 AM

Why bring up the 2,000 lb MC bomb specifically Shooter? Curious.
Because the Lancaster's bomb bay is long, narrow and not very tall. The 2000 pound medium case bomb only fits on or near the planes CL. If it was required, the B-17 can carry eight of those bombs to the Lancaster's six. (But only with the bulged doors! Otherwise it's only three!) The B-17's bomb bay is short, but twice as wide and three times as tall as that fitted to the Lancaster. To take part in this argument, you have to get past what was done for strategic reasons and embrace the ideas of what could have been done IF it was required! Did you know that the last Lancs could carry 18 X 1000 pound short fin bombs instead of the 14, the rest of them could tote?

what total rubbish you spout shooter,
i, the B17 could only carry TWO 2000lbs bomb (assuming that it wasnt equiped with the bomb bay tanks as then it was only ONE)
2, the lancaster onl;y need the buldged bay for the 8000lbs and 12000lbs cookies the 2000lbs could and were fine in the no buldged bays
 
3, the B17 bay was no wider than a Lancaster (it was taller but it tappered and you could only mount 2000lbs at the bottom of the bay) in fact based on the space round the bombs I would say that the Lancaster bay was acryually wider (although this may be optical due to the B17 losing so much for the central walkway)
 
4, the Lancaster had no problem carrying 6x2000lbs (two rows of 3) so this makes your argument on bomb placement disproved
 
5, why would buldged bay door restrict the amount of 2000lbs carried? the lancs bombbay was of uniform depth, if 1 2000lbs could be carried in a non buldged bay then the full 6 could be - very faulty logic there shooter
 
you have NEVER provided evidence that the load you claim was possible (and still argue despite being shown numerious books that state otherwise)
 
You claim it might be done the rest of the universe claime it could and wasnt, as it is clear that it never happened it is up to you to show that your claim that it was even possible hold water
 
You need to get past your need for the B17 to be a better bomb carrier that it was and embrace the fact that its bomb bay was tiny

highly relevent

3, the B17 could not carry bombs beigger than 2000lbs internally
Not true!

completely true and well documented 
4, the B17 could not carry more than 2x 2000lbs internally
Not true.

  completely true and well documented 
5, the Lancaster carried more bombs further than the B17 was capable of
Not true! Since the B-17 carried about 1/3rd more gas than the Lancaster, and was more efficient aerodynamically, it could fly about 40-50% farther than the Lancaster at any given weight and altitude.
needed to give up half its bomb bay for that extra fuel  and as the Lancaster carried far greator load to far more distant targets I say you are wrong again
 
6, the Lancaster carried larger bombs than could be carried by a B17
As far as I know, no Lancaster mission ever carried any 2000 pound MC bombs. Although I freely admit that it could have done so if they replaced the 4,000 "Cookie" or replaced all five or six of the CL bomb shackles with three 2000 pound types evenly spaced down the length of the bomb bay, to carry three 2000 pound bombs.
 
and a B17 could not carry a 4000lbs cookie at all, it could only carry 2 read that again TWO 2000lbs max and its max internal load was 6 x1800lbs (not the 6x2000lbs you claim ) oh and were is you evidence that the lanc could carry only 3 2000lbs MC bombs as i dont see any here

Your entire point of all of the sub points above is proof that they chose to do those things at the expense of doing other things! Those were "Strategic" choices made for Strategic reasons! If the Lancaster had been required to fly in broad day light at higher altitudes to avoid flack while carrying more armor and weapons, the weight of those items would have subtracted from the bomb load.
 
If the Lanc had been designed that way then it would have had different design criteria and it wouldnt have been a Lanc, by the same argument had the B17 been used at night it could have flown lower carried less guns and armour and cariierd more bombs - oh wait a minute it could carry more bombs could it as it had such a small bomb bay it could fit any more in
 
 Then they would have been forced to increase fuel storage which would have forced a smaller bomb load. The addition of more weapons would have caused more drag and further reduced the range and bomb load. And finally, if required to form up into large masses of planes flying in formation, their range would have been reduced even further.
 
yet I can find noting that said the Lanc was lacking range, I can however find plenty sayinb that the B17 needed a big rubber fuel cell stuck in the bomb bay to make its range

There is no magic here from either plane, B-17, or Lancaster. The rules of aerodynamics are immutable. The B-17 was faster on less power and thus more aerodynamic than the Lancaster.
 
 It was a more refined design that was stronger,
you claim but not proved, the Lanc was a very strong design (remember it was designed for catapult launch) I can find no evidence that ANY source thought the Lancaster airframe was weak, in fact you are the ONLY source to even sugest this, the B17 was hardly without faults that weak rear was a known problem thoughout its life
 
 but Massed less as proven by their Empty Equipped and Maximum Take Off Weights and reputations for toughness on one hand and frailty on the other.
 
here we go again Shooter imagined fraility oh the Lancaster, an unsupported theory that has no evidence to support it and pretty much disproved by history
Just because you have a pet theory does not make it a fact, no matter how many times you repeat it
