Nonsense. Roosevelt would have asked for the bombers and Churchill would have agreed.

30 bombers represented far less than .5% of Lancaster production.

You don't know that. There is a lot that Churchill could do, but if Harris said no, and he had the support of Portal, Churchill would have gone along with it. He listened to those who knew what they were doing...
 
How do you know? Not even Roosevelt knew the nature of the weapon! He wasn't included in the secret list! Not even Arnold nor Tibbetts knew! There's no way the British are gonna be let in on it!
 
We've beat this to death many pages ago - "Could have, would have should have." This mystical Lanc VI was still an obsolete design and had no further growth as a viable front line bomber after WW2, let alone being a nuke bomber. It's limitations were well documented pages back. If it had the potential to deliver nuclear weapons during or after WW2, then this would have never happened...

 

The typical mission was low-high-low, with the high portion limited to the vicinity of the target. Cruise speed is almost irrelevant.

Your numbers are wrong:

Range with one 400 UK Gal (1,818 l) Aux. fuel tank and 7,000 lb (3,180 kg) bomb load 2,680 miles (4,310 km) (62K lb TOW) A "Silverplate" Lancaster would have reduced weight and increased service ceiling.

The Tallboy mission against Tirpitz was over 2200 miles.
 
My figures are based on those recorded by the A&AEE on the use of the Grand Slam by a B.I Special, and a Upkeep mine having roughly the same weight as a Little Boy. Figures for Tall Boy carrying Lancasters have not survived the war. Silverplate Lancaster? There's that mythical dragon again...

The Tall Boy mission against the Tirpitz was flown in Norway, not the mid Pacific.

Give up mate.

UK and Cdn scientists were working on the Manhattan project, including Los Alamos, and the bomb design originated from the UK's MAUD report. Churchill and King were "in the know".
 

The Tallboy mission that sank Tirpitz was flown from and to Scotland.

Grand Slam weighed 22K lbs or 12K more than the a-bombs and had to be carried externally.
 
Got any evidence to back that up? A document, anything other than your imagination and wishful thinking?

see my previous post including:

"The text [of the Quebec Agreement] was typewritten. At the bottom, in Roosevelt's handwriting, was the single word Approved and the date August 19, 1943 . The signatures of the two leaders, Roosevelt and Churchill, were appended. It was then a secret document and long remained so; the text was not seen by the public until tabled in the House of Commons at Westminster in April 1954.
The preamble noted it was "vital to our common safety in the present War to bring the Tube Alloys [A-Bomb] project to fruition at the earliest moment." This might be more speedily achieved if all available British and American brains and resources were pooled. It was agreed that:

  • "We will never use this agency against each other.
  • "We will not use it against third parties without each other's consent.
  • "We will not either of us communicate any information about Tube Alloys to third parties except by mutual consent."
The fifth and last section [of the Quebec Agreement] outlined arrangements for "full and effective collaboration." It provided for a Combined Policy Committee, to be set up at Washington, composed of:
  • The U.S. Secretary of War [U.S.]
  • Dr. Vannevar Bush [U.S.]
  • Dr. James B. Conant [U.S.]
  • Field Marshal Sir John Dill [U.K.]
  • Colonel the Rt. Hon. J. J. Llewellin [U.K.]
  • The Honourable C. D. Howe [Canada].
... The new committee met for the first time at the War Department on September 8...." (1943)

Roosevelt did know. Why would you possibly believe otherwise:

Sorry, but nothing there proves that he knew about the atomic bomb. Its also approval for the Manhattan Project, the exact nature of which very few knew. All it does is prove that he knew the USA needed uranium for a weapon, the nature of which and what it was capable of HE DID NOT KNOW. It wasn't common knowledge like today. Memory telescoping, I think that's called.
 
So, RCAFson, to redeem your argument that has been disproved, you are taking to picking out scraps to validate your stance? Remember, doesn't go any further to justify your views...
 

Your post above shows a profound ignorance of this topic. Roosevelt was always briefed on a-bomb development and there is an abundance of primary source documents to show this. At the Quebec conference he discussed the bomb with King and Churchill and signed a memorandum of agreement about it's use and it established a Joint UK-USA committee to oversee it's development, and as I previously stated the A-bomb project was initiated by the UK and and the UK MAUD report, and was passed to the USA.

Roosevelt and the bomb:

Franklin D. Roosevelt.

There was one aircraft built, and it never proceeded to production. It was a failed design.
