ALTNAV 1922-1941 (01/08/19)
These Mods are available for AE and have 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. The Treaty Years give way to the ramping up of World War Two. Other then Treaty Modifications, the rest of the Japanese building program occurs historically. IN this AltNav, Yamamoto serves as the historical Admiral and his vision is ignored to the detriment of the Kaigun.
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. A slightly higher 10:10:7 ratio between Great Britain, the United States, and Japan is agreed upon, allowing for several new outcomes:
1. The Ratio Change to 10:10:7:
a. The Japanese argue to keep the nearly complete battleship Tosa and the Amagi-Class battlecruiser Ishitaka. The Americans gain the fourth Colorado-Class USS Washington and the Battlecruiser USS Constellation (while scrapping the old battleships Florida and Utah and making the Wyoming into a gunnery training ship to maintain balance), Great Britain gets the option to build a pair of Super-Hoods.
b. Tonnages are left open for the British to build two 35,000 Ton battleships (Rodney and Nelson), the United States has 28,000 Ton available, and the Japanese have 18,000 Ton open for new Capital Ships. These warships are designed through the late-20s and are authorized for building at the time of the London Naval Conference. The United States builds a fast Battlecruiser (USS Chesapeake) armed with 4x3 12" Guns while the Japanese build a Light Battlecruiser named Chichibu (2x2 16.1" Guns).
2. The whole subject of CVs is reworked with slighly increased carrier tonnage allowed bringing a slightly different creation to each flee'ts starting CV forces::
a. Two 'experimental' CVs (two Hosho's and two Langley's) are allowed to be built for further carrier experimentation. The Americans convert USS Langley and USS Ely to CVEs and they begin the war at the Panama Canal. Japan has IJN Hosho and Ibuki.
b. Two BC to CV conversions are still allowed.
c. The Americans use all their Treaty tonnage to make create a solid CVL, after the failed design of the Ranger, named King's Mountain and Wasp becomes a 4th Yorktown-Class CV.
d. The Japanese back off the failed Ryujo design to build IJN Ryukaku and Karasu while Soryu enters as a Hiryu-Class CV.
3. The Big 3 allow for more research into 'Cruiser' Submarines. Since no one had any real idea of where submarines were headed, this allows for further experimentation. The Americans build an additional Argonaut, Narwhal, and three Seaplane carrying subs. The Japanese add three Mine Layers and four large ocean-going Glen SS, 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%). Japan is authorized to build a total of 14 CAs while the Allied Forces have 18 each.
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. This brings no change to the Treaty since Japan was already at 70% in this category.
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. The nations are allowed with ONLY these two vessels to place up to 8" guns on them. USA builds CLV Charlotte and Jacksonville (3x3 6" and 18 Planes), GB builds CAV Melbourne and Wellington (sold/given to those respective navies with 2x2 8" and 15 Planes), and Japan finishes up with CAV Kushiro and Tokachi (3x2 8" and 27 Planes). These hybrids are not true, useful CVLs nor 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 two additional Myoko-Class CAs and completes the Mogami-Class as CAs instead of CLs. The oldest Japanese CAs (Kako and Furutaka-Classes) are downgraded to CLs with 6" guns replacing the 8" turrets.
As war clouds gather on the horizon, the United States makes several important decisions (1) to slightly reinforce the Asiatic Fleet with an additional CA, CL, and 4 modern DDs, (2) Admiral Hart also decides to follow his inner thoughts and begin development of Cebu as an alternate anchorage, and (3) the Scouting Force, commanded by Vc-Adm Wilson is sent south to protect the Philippine reinforcement TFs going to the Philippines (The Pensacola TF) and the empty TF returning from the Philippines (The Chester TF).
Japan deploys its few new ships to protect the Invasion TFs coming from Babeldoap and Cam Rahn Bay as the Kido Butai steams towards its rendezvous with destiny at Pearl Harbor…
