What if? Alternate history of the Boeing B29 bomber development. What if the experimental Allision twin V24 3420 heavy bomber engine had been fully worked up by 1940? Over 3,000 high altitude hp to start off with and increasing to almost 4,000 take off hp by the end of the war in the Pacific against Japan.
Instead of barely carrying 10,000 to Tokyo and back with initial engine life of 15 hours with the Wright 3350 air cooled engine, instead with the Allision things started off carrying 20,000 pounds to the North Islands, then progressed from there carrying 30,000 pounds of General LaMays (sp?) incendiary bomb campaign?
The big unanswered question is would have such a design change resulted in such improved B29 flight performance and would have that made any big difference in the war against Japan? Enough of a considered difference that the use of the A BOMB was considered not necessary as Japan surrendered months earlier?
And ... never start a paragraph with a conjunction. No .... wait. And if the A BOMB had NOT BEEN USED against Japan because they surrender somewhat earlier what kind of difference would THAT have made in a post World War Two environment? How would have the Cold War played out? Just some questions.
