So the United States did, in fact, know about duralumin alloy (aka the 2000 series as designated by the IADS - International Alloy Designation System) before World War II despite your claim to the contrary.
I don't know why you keep claiming this when you I told you three times that your understanding is false. I don't want to accuse you of trolling. Don't persist in the error.
2. The reason that Japanese propellers (not engines---PROPELLERS (duralumin alloy unknown to the Americans, Japanese invented and not duplicated until mid 1943)
The type of Durainum alloy the Japanese invented was used in their propellers as well as the stiffening members of the air frame> I cannot help you if you cannot READ what I wrote.
Gross incompetence can be classified as criminal per Title 10, Section 892, Article 92 of the USCMJ, IIRC. Again, based on the available evidence, I disagree with you that it was a mystery why technical intelligence from analysis of Japanese (and some American) material from the field got to the needed people in the given time frame.
I'm not even going to dignify that nonsense. "Dereliction of Duty" is not incompetence. Dereliction of duty is defined as willful action to perform a duty as in refusal to obey an order or doing harm to oneself in such fashion so as to be physically unable to carry out an assigned duty. COMPETENCY has nothing to do with the willful decision or act to refuse to perform a duty.
In the case of the atomic playboy (Blandy) he argued that the operational record being developed in the first year of war operations with a brand new weapon system to the United States Navy (The submarine was being used in war by the USN as a strategic weapon for the first time, and they were having EXACTLY the same kinds of problems the British and Germans encountered 2 years earlier. The British and Germans were on their SECOND outing with submarines. It took the British and Germans about 2 whole years to fix their issues, so the 18 months it took Blandy was actually not out of technical expectations once he got verified field testing and forces at sea op-feedback that was concrete and testable: unless you were the ones who had to fight and die with the non-working weapons and launch platforms.) was unclear as to whether it was human error or mechanical fault that was the cause of the poor probability of kill by the Mark XIV.
He did act as fast as he could, once his technicians determined for themselves that there was a common mechanical problem across the entire torpedo line in use by the USN that involved a botched depth control setup. His stubborn refusal to have Bu-Ord look at the tumbled gyros, the case leaking in the power unit of the torpedoes and the exploders was based on his presumption (Which has actually a good historical precedent in USN weapon usage history from the War of 1812, forward...) that when a weapon fails, it is because of lapses in training and understanding the idiosyncrasies of the weapon. HUMAN error. In effect Blandy was correct about Human error, but for the wrong reasons. The weapons failed because of inadequate testing and weapon proof at the front end and poor manufacture and quality control in production. The enduser crews did not know what they were doing because they had no practice with working exploders aboard the torpedoes and they did not make enough simulated live war-shots against target sleds in sufficient numbers to show the torpedoes had all the problems in the production runs even in the five years of peacetime when
the USN should have trained up and prepared for war and had the money and incentive to do such active training.. Guess what BASTARD was in charge of the fighting forces from 1937 to 1939? That chief of naval operations was
William D. Leahy. He was followed by another bastard.
Harold R. Stark. 1939-1942.
Now the bozos who did not do their jobs at Bu-ord to fix production of the torpedoes at Goat Island were guess who?:
William D. Leahy, 1927–1931 and
Harold Rainsford Stark, 1934–1937 (them, again). Guess that would be the fools I would've court martialed and had shot for dereliction; if I were the 'right' kind of (Teddy) Roosevelt, but Franklin preferred to promote his discovered buffoons out of the active navy to some harmless place where they could do nothing to further damage the Republic. Leahy occupied the "ceremonial" place of chairman of the Joint Chiefs while Marshal and King ran the real war. Stark, that other poltroon, was sent to Europe to run the USNEUR "diplomatically" and attend all the RN cocktail parties in London, about the only thing he was good for as a known stuffed uniform. Royal Ingersoll ran the REAL Atlantic war.
