Thought I would bring up the ALTHIST that we have based the changes upon:
The Treaty Mod (Scenario 45)
ALTNAV 1922-1937
The Treaty Mod for AE has been created to reflect a slightly different outcome of the historic Washington and London Naval Conferences to cover the time of 1922-1937. With little changes and tweaks to the Treaty System, a slightly a-historic outcome is produced. It should be noted that no changes are made to any major power from 1937-1941.
The Washington Conference
Secretary of State Charles Evans Hughes blueprint for naval disarmament gets out and the Japanese stonewall a Naval Conference for a full year. After considerable bickering and pressure being brought to bear, the Conference does take place in 1922 and disarmament is agreed upon, however, there are additions allowed due to the added time to get the meeting going. The whole Mutsu debate is scrapped due to Mutsu actually being ready and deployed at that point. While maintaining the 5-5-3 ratio between Great Britain, the United States, and Japan, there are several new outcomes:
1. The Japanese then argue to keep either a Tosa or one of the Amagi Class battlecruisers. The Americans carry the day in arguing for the Lexington-Class battlecruisers being completed. They gain the Ranger and Constellation (while scrapping BB Mississippi to maintain balance), Great Britain gets the option to build a pair of Super-Hoods (while additionally scrapping Royal Sovereign), and Japan completes Amagi-Class Ishitaka.
2. The whole subject of CVs is reworked:
a. Two 'experimental' CVs (two Hosho's and two Langley's) are allowed to be built for further carrier experimentation. The Americans still convert USS Langley and USS Ely to seaplane carriers and they are both then transferred to the Asiatic Fleet.
b. Two BC to CV conversions are still allowed but further treaty tonnage is added for one more CVL to be built by both Japan and USA. The Americans build the USS King’s Mountain (proto-Independence Class) and the Japanese back off the failed Ryujo design to build IJN Ryukaku (a proto-CVL as well).
3. The Big 3 allow for more research into 'Cruiser' Submarines. The Americans build an additional Argonaut and Narwhal, the Japanese add three Mine Layers, and the French add another Surcouf.
The London Conference
Moving on to the London Conference (1930), the subject of Cruisers is re-worked:
1. Japan--at all costs--sticks to its goal of 70% for CAs (instead of 60%). This allows for GB and USA to build two more CAs (USA: Burlington and Rome) while Japan gains one.
2. Great Britain--who nearly scrapped the treaty due to the issue of CAs and CLs--stands firm over its argument and forces a larger tonnage for CLs. USA adds USS Anchorage and Dallas and Japan begins building their scaled-back Mogami-Cruisers.
3. Both Japan and the United States were looking at hybrid Cruiser—CVs and they force Great Britain, following the example set with the Washington BC—CV Conversions, to allow for two hybrids each to be built in the early-30s. USA builds CLV Charlotte and Jacksonville, GB builds CAV Melbourne and Wellington (sold/given to those respective navies), and Japan finishes up with CAV Kushiro and Tokachi. These hybrids are not true, useful CVLs not are they true, useful cruisers but they have a unique niche in 1941 and ALL of them can be converted into carriers later in 1942.
***It should be noted that to take maximum advantage of the revised Treaty tonnages, Japan converts several of the oldest CLs into fast ML, builds additional Myoko-Class CAs and keeps the Mogami Class as 6” CLs.
Reluctant Admiral 8.0 (Scenario 50)
1937-1945
The Reluctant Admiral is a Japanese 'what if' scenario based upon a greater contribution by Adm. Yamamoto Isoroku to the development of the Kaigun in 1936-1941. The premise of the Mod is that Yamamoto exerted a much greater influence first on the Japan Naval Aircraft Industry, then as Deputy Navy Minister, and finally as Navy Minister itself. Yamamoto chooses, at great risk to his life, to forego command of the Combined Fleet and dedicate himself to preparing Japan for a war he didn't want.
He adds two new slipways for Fleet construction to facilitate a different, final pre-war expansion of the Kaigun. New and expanded Naval Yards, Heavy Industry, and Armaments are added at tremendous cost for the Japanese economy as the Admiral attempts to prepare Japan for a possibly long war. In so choosing to do this Yamamoto then changes the 4th Circle Building Plan replacing the 3rd and 4th Yamato-Class Battleships with improved Shokaku-Class CVs and a pair of Kawachi-Class fast Battlecruisers, two Tone-Class CAs, an accelerated Light Cruiser deployment, and additional destroyers. Quick, reasonably cheap carrier conversions are moved forward seeing all of the pre-war CVs/CVLs deploy by December 7th or at slightly earlier dates in 1942. Though only a few of these new ships are ready on December 7th, these additions shall make the Kaigun a force to be reckoned with well into 1944.
The Japan Naval Air Arm is changed so that everything is staked to the Zero Airframe with a specialization of the Zero into a Land-Based Interceptor as well as CV-Based Fighters. Research and production expansion is achieved by streamlining the air industry (cutting several models) while bringing forward second generation aircraft: Judy, Jill, etc… By great effort the IJNAF deploys nearly all new aircraft on December 7th.
On the ground Yamamoto reorganizes the SNLF units into a Brigade-Sized offensive force and—knowing it will be a war of attrition—converts many Naval Guard into enhanced units with Coastal Defense artillery (using guns taken from refitted warships) for a stronger defensive unit. Additional small units are added to the IJN’s Troops and support units better reflecting Yamamoto's foresight into base building, defense, and expansion needs. While all these units are small and not in great number they promise to help the Japanese war effort.
The foresight of the Admiral pays off during late-1942 and 1943 as new ships, aircraft, and ground units enter into the Japanese Order-of-Battle, however, the cost is steep. Though expanded and using modern aircraft many Japanese Naval Air units start with their experience lowered to reflect the dilution of the experienced pilots into new units that start in Japan or arrive during 1942-1943.
Supply and fuel reserves start at a much reduced state. The Japanese MUST take the DEI as fast as possible!
Once war begins RA postulates Yamamoto’s influence upon the wartime Kaigun.
Several more Shokaku CVs are ordered as well as another pair of CAs, and the conversion of several CLs into CVLs. First class destroyers are accelerated and emphasis is shifted to the AA Akizuki-Class at the expense of the more balanced Yugumo’s. Manpower is at a premium within the Fleet so Submarines, Escorts, and ASW forces all see a major retooling reflecting the Japanese quality over quantity belief. Yamamoto chooses the immediately useful projects, large APs converting to CVEs, better 2nd-class destroyers, fast transports and coastal defense fleet.
It should be noted that not all the changes are for the Japanese. RA 6.4+ brings major additions and more choice for the Allied Player. The Allies see continued major changes in their starting locations, new air units, the addition of Training Squadrons on mainland USA to allow for an American pilot training program, enhanced aircraft production numbers, additional Allied FP groups, several ground units, a French Squadron at Noumea, the use of CLV Charlotte (a Flightdeck Cruiser), a CLAA conversion for the Omaha-CL, an additional pair of CVLs, and optional conversion of the Kittyhawk Class AKV, Tangier Class AV, and Cimarron Class AOs into CVEs. The added warships reflect a ‘stopgap’ counter to the increased Japanese strength found at war’s start.
Between the Storms and BTS: Lite
Scenario 50 and 52
Warship Construction AFTER the Treaty Years (Between the Storms: LITE version with Owaris and later construction versus Between the Storms with Yamato and Musashi)
Battleship Question and Decision
After abandoning the Treaty System, great discussion goes into the first new battleships to be built by Japan since the Nagato Class. The choices ends up centering on building two modern, fast conventional battlewagons as opposed to the mighty Yamato-Class. The prohibitive factors of cost and time finally swing the decision to creating the Owari-Class (3x3 16.1" Rifles). While not sounding too exciting this change brings about a very interesting situation. Both Yamato and Musashi required their slipways to be expanded in length. The expansions were hugely expensive and took MONTHS to finish. By building the Owari-Class BBs the Japanese clear these slipways 12-18 months faster. The net result is two modern BBs (28 Knots) join the Kaigun BEFORE Pearl Harbor and their successors (two B-65 Class BCs) are either finished or near complete at war's start.
Two additional Owari-Class Battleships are ordered under the 4th Circle Plan as well.
Command Cruisers
While debate rages on about the new battleship design, a new class of heavy cruiser is initiated. The proposed Tone-Class floatplane CA is discarded for a balanced, more capable cruiser. These large cruisers are better called command cruisers. The Niitaka-Class grows to over 15,000 tonnes and carries 4x3 8" guns, heavy torpedo armament, impressive secondaries, and strong floatplane complements. These fast, rugged cruisers are planned to be a six ship class. The initial two are complete at war's start, a second pair coming in late-1942, and a final pair in 1944.
