On 11 January 1942, the IJA completed a study on whether Hawaii could be successfully invaded and, if it could, what would be needed to retain the islands.
He estimated that under Japanese occupation, figures would be a bit higher -- 3 million tons annually, or about 30 ships a month to keep the population supplied. Also, another 30 ships would be required each month to transport military equipment.
@Vausterlitz1 The conclusion was that Japan's merchant marine was too badly overstretched with various operations and transport duties to accomplish this.
Konstam's book is wonderful for most of the journalistic "Who, What, Where, When, How, & Why" on Dec 10, 1941, but it leaves out how the command control, communications & intelligence worked for the IJNAS Rikko Kokutai and why it came into existence in time to destroy Force Z. 3/
"MacArthur's Pearl Harbor" AKA the Dec 8, 1941 destruction of FEAF air power at Clarke Field is the subject of this thread.

One of the important things to know about General Douglas MacArthur was that almost nothing said or written about him can be trusted without extensive research to validate its truthfulness.
There were a lot of reasons for this. The biggest being that if the Clinton era 2/
political concept of “The Politics of Personal Destruction” had been around in the 1930s through 1950s, Gen. MacArthur’s face would have been its poster boy.
Everything he did was personal & that made everything everyone else did in opposition to him “personal” to them. Thus
The successful surprise Kido Butai carrier fleet movement to Pearl Harbor was the result of a sophisticated the denial and deception measures to blind allied signals intelligence as to their movements. 2/
A deceptive movement that worked thanks to the hard work & diligence of both Adm Isoroku Yamamoto's staff planners as well as pre-war Japanese intelligence.
The IJN played the US Pacific Fleet's operational tendencies like a harp.
The issues that @fortisanalysis founder, @man_integrated spoke about recently piece on why the USA may never recover from the current supply chain disruptions have a historical analog in WW2 military supply chains.
His blog's comparison of NASA's SLS based Artemis architecture versus a Lunar program based on Starship makes the point.
This is a phase change difference in access to space akin from the X-Atlantic air travel jump from Charles Lindberg to the wide body jet in 5-years. 2/
For the logistical types, these are your current price points:
$100,000/kg for LEO bulk cargo
$1,000,000/kg(+) for deep space exploration.
Starship will do 100 ton (+) chunks for <$10m per launch.
It will be launching several hundred times a year w/in 5-years. 3/
