Thanks for the info. I will add it to my reading list.

It is a great book!

There's a couple of others on the same subject that are very good.......

"Freedom's Forge" by Arthur Herman relates how the auto industry and ship building industry transformed to equip American.  This is a really good read.
Up until then the aircraft industry was mostly a small industry of companies that built small quantities of aircraft on an almost hand made one-off custom basis.
Auto people inspecting a major aircraft maker were shocked to find that there was really no standards or specifications and parts didn't interchange.  They didn't even have any real documentation.
With guidance from the auto industry aircraft began to be built like cars and trucks.

"A Call To Arms" by Maury Klein is a massive book, actually a little too much so.
This one details more of the problems in gearing up for the war caused by Roosevelt himself and his radical New Dealers.
Roosevelt constantly interfered and gummed up the works by his playing off one person against another.
A person would be called to Washington to agree to head up an effort and would leave the Oval Office assured that he had the authority to get things done.  Only to later find that Roosevelt had given the same authority to another person.
This was Roosevelt's normal way of keeping all authority in his own hands while seeming to be giving authority to others.
This caused endless confusion and in fighting among committees over who was in charge and caused major delays.

The New Dealers wanted to win the war, but were more concerned about protecting their New Deal programs and preventing big business from getting any credit.  They caused endless delays in production and the accompanying causalities all over the world.

Most people think that the war was about to start, America instantly changed over to war production and won the war with a tidal wave of equipment.
In fact many businesses were very reluctant to engage in war production for a number of reasons.
One was because large companies like Dupont had willingly produced huge amounts of material for WWI, then in the 30's had been accused of being war profiteers and "Merchant's of Death" by the press and New Dealers.
That's why companies like Dupont were slow to take production orders, and often worked on an at-cost no-profit basis in order to prevent another post-WWII witch hunt.

Other problems was with getting the government to tell manufactures WHAT to make, and assuring the companies that they'd actually get paid.  
The more radical New Dealers thought that the companies should be nationalized and not be paid and the companies were uncertain about whether to take the chance of not getting paid and in fact, being taken over by the government.

This was made worse by the Roosevelt New Deal government bureaucrats being unable to reliably tell a company exactly what they needed to make.
It was common for companies to get phone calls telling them to stop making civilian products and start making military equipment, only to get another call days later telling them to make some other type of military equipment.
This was made worse by different organizations or committees giving conflicting orders because Roosevelt had given several organizations conflicting authority so he could maintain control.
This left the companies caught between two or more battling committees, both saying that they had authority.

Once all this was ironed out and the power of the more radial New dealers was lowered American business did just drown the Axis in high quality equipment.
It was a fact that an American private wore a better uniform then most British or German officers.

While there's a popular claim in Europe and Asia that America only won because of our massive supplies of equipment, the fact is that young American soldiers, sailors, and Marines went toe to toe with the Axis and beat them on the battle field by out thinking and out fighting them.

Excellent, I have requested both from my library.

One of Jackson’s Foot Cavalry by John Worsham.  I found that hard to put down.
