Comparative Study of B-17 vs B-24

[WorkinStiff]

1944 AAF study: "It would be desirable to increase B-17 production and decrease that of the B-24 because the former airplane (B-17),is a much more effective combat weapon".....www.uk-us.org/stinet/warproduction.pdf

[evangilder]

That document looks oddly familiar, I think I have a copy of it somewhere. There was more to it than what you mention:

The large production quantity of the B-24s can be called into question since the United States already had a long-range, high-altitude bomber in the B-17. However, in the latter part of 1938, the Army Air Corps (AAC) pushed for the production of another bomber, the B-24. Some might argue that the reason for the production of the B-24 was that the AAC requested a plane with better range and better performance than the B-17, but this research shows that the B-24 did not outperform the B-17, as proven by historical documentation which included results of accident causes and correspondence from senior AAF officials comparing the two aircraft. Another argument might be that B-24s were produced because the B-17 contractors could not mass-produce a sufficient number of B-
17s in support of the strategic bombing campaign in Europe. Yet another argument is the cost benefit factor of producing a competitor to the B-17, thus maintaining lower costs for both of the planes. A political argument for producing the B-24 could be the fact that having multiple contractors produce thousands of aircraft in different locations spread the job and employment benefits across the United States. This research will show that the reason for producing the B-24 was actually a combination of all these factors.

All these problems would have been easily and intuitively overcome simply if Consolidated had accepted to build the B17 under Boeing licence, for a much lower gain of course.At the place of the 20.261 Liberators built ( VS 12.700 B17s from Boeing) they could build the same number of Flying Fortresses , and we are overlooking here the production of spare components of the aircraft with the consequent economical and uniformity operational advantages...Reuben Hollis Fleet , president of Consolidated was invited in 1938 together with his Chief Engineer to visit Boeing factory in Seattle under proposal from USAAC, and asked to get the licence for the production of B17, but after a superficial look to the Fortress he answered that"he could build a better aircraft".

THE VOICE THE CREWS:
-nicknames for B17:Jeep,Flying Fort,The Queen,Air Destroyer,Space Ship..
-nicks for Liberator: Liquidator,Constipated Libertine,Convulsive Leviathan,Compulsive Lumberer and others ( unrepeatable).

In my opinion US Air Force and Gouvernment had to impose to the industrial leaders to build the best aircraft simply for impelling war necessities.

On the contrary someone in the headquarteers probably had very good motivations to give a balanced fair gain for each industrial corporation so that nobody were disappointed.

this situation is not very different from the Italian public competition for a up-to-date interceptor in 1938 , when 4 (!) aircrafts were chosen , the highest numbers for FIAT G50 and (up-to-date?) CR42, then Macchi C200 while the worst option was left to the best, Reggiane Re-2000!

geez just go ask a B-17 vet or a B-24 vet as to which one is better. No don't I have almost been punched out. Talk about a rivalry between these combat veterans. Both bombers did the job well. The Lib did not have the altitude and on may craft no belly turrets which the Lib vets thought the Luftwaffe took advantage of.........

[P38 Pilot]

Erich is right. Talking to a Veteran is better than a documentary. If you ask me, both bombers were good for their time. The B-17 was useful in Europe. The B-24 was useful over in the pacific.

[SM79Sparviero]

No don't I have almost been punched out. Talk about a rivalry between these combat veterans. Both bombers did the job well.

My nickname remembers an ugly unchbacked wood-made aircraft that was born to carry mail and passengers, and sacrificed itself to strike HMS Rodney by a torpedo.How can you think that I don't share this opinion with you?

Some of the main deficiencies of B24:High wing load that caused troubles in take-off and landing and forced the pilots to keep a rigorous up-and down limit in speed;a chaotic arrangement of the cockpit ; a bad visibility for the pilots that could see in take-off/landing mainly the barrels of the front two 12.7 Brownings ( except for the first series, without the turret); a bad stabiliy when it dropped bombs, so that some pilots that had previously flown with B17 called Liberator "a swinging chair"

Much worse, if compared to B17 it couldn't bear heavy damages in battle.

It is exclusively for respect to those gallant airmen that didn't come back home if I wonder why B24 was chosen at the place of a stronger and more reliable bomber.
I hope it was not only for the profit of Consolidated .
Exactly as I have always wondered why Fiat G50 was chosen over a much better but not "politically supported" fighter.

I agree. Maybe B17s would have had more chances to come back from the sky of Ploesti.

[Erich]

according to Luftwafffe veterans in mid 1944 till wars end the US bombers were on even keel with taking punishemnt. New more powerful German HE ammo could take out either bomber without problem and they were both considered fairly easy tagets granted if US P-51's were not out and about

[P38 Pilot]

Yeah. But the B-17 probably proved a tougher challenge for the German pilots who attacked them. The B-17 had more gunners than the B-24.

[Erich]

nope !

the time period I am talking about constitutes a rear facing attack on all US bombers. A bomber without Allied escorts was toast. Both bomber types brewed up equally

The problems on take off involved engine-out situations. The B-24 flew beautiful with the Davis Airfoil when all engines were running. Feather one engine and the controls got real heavy.

While the B-24 had higher takeoff and landing speeds than the B-17, training alleviated the initial accident rate.....

Met a fellow recently who's great grandson is now attending the USAFA -he was here watching his great-grandson accomplish his first "jump." This ole fella flew B-24s in the Pacific, we struck up a conversation because my wife's grandfather flew B-24s as well. He was with the "Jolly Rogers," 90th BG early in the war. Anyway this old B-24 pilot commented to me that he always felt the B-24 was faster and the "J" models seemed more modern than the B-17. He did go on to say the -17 was more comfortable to fly and way more stable.

I think if you ask B-24s and B-17 veterans which ones were better, those guys who flew the B-24 in the Pacific are going to be more favorable toward the B-24

[plan_D]

The B-24 dropped just as much tonnage, if not more, than the B-17 in Europe. It obviously was doing something right! It dropped more tonnage in the entire war than any other bomber.

From a grand stand-point, if not a pilot point, the B-24 was superior to the B-17. With some field modifications the RAF in the CBI managed to get their Liberators carrying 8000 lbs worth of bombs over 1,100 miles!

I will give detail when I find the name of the chap that discovered that through the use of extra fuel tanks and playing with cruise control.

[WorkinStiff]

B-17 crewman said that the best escort was to be flying on a mission with B-24s as the German fighter pilots would ignore the B-17s and go after what they regarded as easier kills; the B-24s.....
I believe that B-24s were chosen for the initial Polesti raids because of their longer range...They were flying from Libya....

[mosquitoman]

The B-24 is better IMO, it has longer range, larger bombload and faster. At the right altitude a B-24 on 3 engines could overtake a B-17 on all four

[Erich]

the Germans would not ignore the B-17's and go ater the B-24's. This is a typical Ww 2 US mythical statement. The Germans were vectored in and then up to the individual Staffelkapitäns as to which bomber pulk's would be selected for the attacks
