-1 for the idea. B29 came in pretty late (1945) and the ordance is too heavy. Even if it would be added it would have to be perked 300+.
A pretty good reason why no NUKES!

Two thing: 1) remove your post before skuzzy see it. 2) B-29 came into service on May 1944, not 1945. 3) Why must a nuke come to mind with the B-29. Two lousy nukes where used, compared it to the tonnage of other ordnance they drop from June 1944 to August 1945.
Here is a comparative chart of other Bombers we have on AH. Bold indicates it out dose the B-29
