Nice, you made my day, among the other great stuff you post, keep it up.
 
I like to think that the Pacific War was a lot more lively that Turtledove makes it out to be. That's my head canon at least.

This being Timeline-191, may I please ask if you mean the Pacific Theatre of the Second Great War or the Pacific War of 1932-1934 (I'm tempted to refer to the latter as 'The Little Pacific War' to avoid confusion ...), though I tend to agree with your sentiments no matter which Pacific War you happen to be contemplating (Though I'm especially interested by the earlier conflict, since it's intriguing to wonder what a US-Japanese War fought in the 1930s would have looked like - possibly due to the likely use of biplanes by both combatants - even if the Pacific War of the 1930s seems to have seen failures of diplomacy & will on both sides. One always gets the impression it was a war in which both sides lacked to bases to really press home an advantage and lacked the willingness to take Major Risks - diplomatic or strategic - in pursuit of those bases*).

*Also, a rather neat quotation relating to that conflict occurred to me earlier today "Both sides sought to fight this war on the cheap and made an expensive business of doing so".
 
I asked this question on the FILLING THE GAPS thread, but thought it in keeping with the theme of this one - Might I please ask if any contributor has an idea of what sort of medals Sam Carsten would have accumulated in the course of his long and by no means undistinguished career? (I'm not well enough acquainted with US Navy decorations to make any useful guess).

Well in this case I was referring to the Pacific Theater of the Second Great War. The one we see in "Settling Accounts". Its been the main focus of a small project of mine, to portray the carrier battle mentioned in the book "Drive to the East" that took place somewhere north west of Hawaii. I managed to compile the ships for both sides.

Indeed, a naval war waged between Japan and the US in the 1930s would be intriguing. While it is mentioned that carriers faced off against each other in this war, it would not be the only kind of clash to happen, especially since carrier doctrine and combat as we know would likely still be in development. The lasting impact of this war, I feel, would be in giving the US and the Japanese valuable, yet tough, experiences in fighting a new kind of naval war. This could serve the US well for its war with the British in the Atlantic once the shooting starts in 1941.
 
Would love to see what kind of aircraft carriers Japan had in timeline 191.
Kuroyo Class (includes Hakuyo).gif


^^^ --- One idea I had was that we could possibly see Japan escalate its "Shadow Carrier" program to include more ships suitable for conversion into carriers. In this case, converting some more of the older cruisers they can afford to take off the line and turning them into light carriers, with the reasoning behind this decision partly based on their experiences in the 1932-1934 Pacific War with the US. The picture you see above is the Ibuki, a heavy cruiser hull that was to be converted into a light carrier. Her conversion began in 1943, but it was never finished.
 
Well in this case I was referring to the Pacific Theater of the Second Great War.

It's a little chilling to consider that the United States of America has technically fought no fewer than three Pacific Wars in this timeline; it never ceases to impress me that Timeline-191 just keeps getting nastier and nastier the more you examine the underpinnings of the setting, to the point where it's slightly impressive to have read through approximately 3/4s of IN THE PRESENCE OF MINE ENEMIES (Where the Nazis won) and actually found it slightly more optimistic than the average SOUTHERN VICTORY novel (At least on the level of their being a final exhaustion of cruelty even for the Third Reich ... and possibly because the novel focuses on everyday Germans not in professions likely to attract Nazi ********).

Its a nasty world indeed. It is also a world where Japan and her empire are better time at growing. Now, what that means in terms of naval strength for Japan is likely up to the reader, but considering the actions and operations they have managed to pull off, I'll say that their navy is more capable/more ambitious in this timeline. By how much? Again, up to the reader.
 
I suspect that Japan, having much older and larger dominions than was ever the case in our time, would logically have (and need) a larger fleet to keep them together.

Would the Army versus Navy rivalry still happen here as well.
 

Deleted member 2186

Absolutely, in my opinion. I don't think that will ever go away, even with the timeline favoring Japan.
Well that would be a major butterfly in having the Japanese imperial Army and Navy working side by side.
 
Would the Army versus Navy rivalry still happen here as well.

That would seem to be a racing certainty, especially after the acquisition of holdings in French Indochina & Manchuria; the exact arguments may differ though, with the Army perhaps a bit more focussed on garrisons than on further gains?

I'm going to repeat myself, it makes much more sense for Atago and Takao (the BCs) to be converted into carriers than their elder sisters, it would be both cheaper and quicker. Same for converting a Kii class instead of Kaga. Also anything still on the stocks in 1923 at Yokosuka is a write off as a ship* due to the Earthquake, BC Amagi would be finished quick enough to avoid that, a CV conversion would not be




*As a hulk Amagi is still being used by the JMSDF to this day in OTL

Cool. Though I'm surprised about the the Amagi, Akagi, and Kaga. I figured they would be kept as they were originally planned, because their was no Washington Naval Treaty.
