Major Allied Navies of WWII: Five Problems and How to Fix them January 1939

The opening warns that racial stereotypes could keep naval officials from recognizing useful Japanese carrier ideas.

The exercise limits proposed reforms to ideas and capabilities available to Allied navies at the start of 1939.

France possessed capable ships, but restricted yards, earlier underinvestment, and an aging light-force mix left few quick remedies.

A modified Dunkerque with triple 15-inch turrets could have preserved an established production line instead of demanding a larger new design.

French aircraft production offered a carrier opportunity, but fleet design lacked a clear answer about Mediterranean and global missions.

The King George V class's 14-inch armament reflected treaty and political choices that naval advocacy might have challenged before the design became fixed.

Simpler triple heavy-gun turrets might have reduced complexity and let France exploit Dunkerque's light displacement under treaty limits.

Repulse, Nelson, and Rodney offered practical modernization opportunities when the Royal Navy lacked fast modern capital ships.

A second Unicorn and faster carrier construction could reinforce aviation support in the Mediterranean and Far East.

Britain could fund faster naval expansion by slowing the interwar priority given to paying down First World War debt.

Dispersed construction in Britain, Australia, India, Canada, and South Africa could expand escorts, submarines, yards, and turbine capacity.

Fast tankers built with conversion in mind could provide logistics immediately and become escort carriers when required.

Large early engine orders and factories outside Britain could overcome artisanal production limits and support overseas naval aviation.

Four early Yorktown-type orders could place additional carriers in service during 1941 without relying on wartime hindsight.

Fast seaplane tenders, reconnaissance aircraft, construction battalions, and mobile artillery would make island bases operational and defensible.

With Japan outside the treaty system, the United States could fund more anti-aircraft cruisers, heavy cruisers, and destroyers.

Rapidly fortified island bases could force Japan to commit battleships and heavy guns repeatedly, imposing operational strain.

A distributed Bittern- or Black Swan-type program could provide capable escorts and prepare Commonwealth yards before wartime expansion.

Earlier batch production of escorts could expand the radar, turbine, and 4.5-inch gun capacity that constrained wartime shipbuilding.
