I would like to provide some statistics on ship construction. The Missouri was the last battleship ever completed by the United States, and (aside from the Arizona) is probably the most famous. The hull was first laid down on January 6th of 1941, nearly a year before Pearl Harbor. It wasn’t commissioned until June 11th, 1944. The other three battleships of the Iowa class were:
Iowa – construction started June 27th, 1940; it was commissioned on February 22nd, 1943.
New Jersey – (specific data not available from the source I am using).
Wisconsin – construction started January 25th, 1941; it was commissioned on April 16th, 1944.
As you can see, building battleships was no easy task. Taking approximately three years each to build, had we lost our carriers as well, the Japanese would have had a full year to run around unopposed in the Pacific. Only four battleships were commissioned in 1942 (of an older class than the Iowa), so there would be no serious naval opposition until a full fleet could be built, probably not until 1945 at the earliest.
On a slightly different tack, several planned carriers did start construction before the war. The first of these new ones, Essex, was commissioned December 31st, 1942. By the end of 1943, CV-9 (Essex) through CV-12 (the second Hornet), CV-16 (the second Lexington) through CV-18 (the second Wasp), and a host of “jeep” carriers were constructed. Still, I think that their length of construction (also about 3 years each) demonstrates that building major ships, even in the height of war, is not a quick task. For a modern day comparison, our most recent carrier (not counting the as yet unfinished Ronald Reagan), is the Harry S Truman which was started in November of 1993, and was commissioned July 25th, 1998.
By the way, “Fat Man” and “Little Boy” were the only two bombs we had at that time. We didn’t have one more; we didn’t have any more. Not that we couldn’t make them if given time, of course, but you never have the luxury of time in a war. Tuckerfan, I notice you have a book cite for claiming we had an additional bomb. I’m afraid that I haven’t turned up a reliable cite from the internet yet. I also have book cites of my own, but then it comes down to my word against yours. I have no doubt that your book does say that, I just believe it is mistaken
