  1. We first saw the Kamikaze in October of 1944 during invasion of Philippines, there was a small pause before Iwo Jima, then another before Okinawa. Most ships stayed forward deployed, but some were called back to Pearl for refits. Anytime they saw a Navy yard there were more guns added, but stability and additional crew were a concern. Ships were being launched up through August '45, often with upgrades phased in during final fitouts.

  2. The IJN built to the max before the war, then sank most of their effort into the three huge Yamato/Shinano's. During the war they had a lot of stuff coming back for repair, clogging their limited dockyards. Their economy was about 1/10 of the US, so their shipbuilding was a similar class. They had no clue about mass-production of ships, using scarce skilled yardworkers to custom-build each ship. The US did not ramp up smaller shipbuilding till '39-40, so it was more modern and modular.

  3. All those shipbuilding yards along the Delaware are all gone now, replaced by riverfront apartments and container transfer ports.

  4. Plus another order of magnitude in aircraft production, totally swamping IJN and IJA (and Nazis, with plenty left over for UK and SU).

  5. If you read some discussions of fleet thinking pre-war, there was some questioning of the utility of heavy cruiser versus light cruiser with the advent of the "machine-gun" Brooklyns and the limitations of the treaties on heavy cruisers, which the Navy had built up to in the late 20s and early 30s. They were both the same size, but a 15-gun 6-inch could throw more steel downrange in a couple minutes than a 9-gun 8-inch. Plus there was some prioritizing before the 1940 "Just Build Everything" Two-Ocean Navy Act that was a response to the surprise fall of France and loss of her fleet.

  6. Axis tried similar, like the Type XXI U-boats, but could not master the mentality change where everything has to be modular and interchangeable rather than craftsman-finished.

  7. About 120 escort carriers times around 500 feet each equals around 60,000 feet or about 11 miles long.

  8. The "coarseness" of the data is primarily in the chosen time coordinate of years rather than quarters or months, which is what most of his qualifications were about. Amusing that a ship launched and sunk in the same year would disappear.

  9. The attrition of the IJN air forces during '42 and early '43 really contributed to the speed with which they could operate later in '43.

  10. There are lots of steps involved, and boring out is slow and very intricate. Some steps are measured in weeks. Anything goes wrong, you start all over. And you cannot work on ten at a time...

  11. There were gaps in the numbers to account for CVEs given to the UK.

  12. I don't think 3D printed steel gives you quite the tensile strength that good forged steel does...

  13. Agreed - and add a third line for losses...

  14. The ending shows why people don't want to start - you don't know how long it will last once you really ramp up, and then you have to eat all the remaining investment.

  15. Transfers don't count, nor do the CVEs we transferred to them...

  16. You skipped the "qualifications" part...
