Major Axis Navies: Five Problems & How to Fix them in January 1939

The opening sets a January 1939 no-hindsight exercise and explains why evidence, incomplete sources, and human fallibility should temper confident judgments about navies.

A traditional contrast between conservative incrementalism and liberal sweeping reform becomes a way to think about naval procurement and institutional change.

World War II mythmaking can reduce the whole Kriegsmarine to Bismarck and the Type XXI U-boat, obscuring the navy's wider institutional record.

A Kagero-derived destroyer trades some gun and torpedo complexity for depth charges and ASDIC to protect fast Japanese fleet units.

Japan cannot repair its industrial weakness in one year, but a January 1939 program could expand infrastructure and obtain German synthetic-fuel technology.

Capturing resources is strategically hollow unless Japan can ship them home through protected sea lanes with enough escorts and fuel.

Publicly revealing Japan's 18-inch-gun battleships in 1939 might disrupt British and American construction programs and buy Japan time.

Kure, Nagasaki, and Yokosuka could build giant warships, but Japan lacked enough large docks and building ways to sustain a broader program.

Italy enters the exercise with a balanced fleet, but needs larger fuel stocks, more escorts, and industry capable of sustained production runs.

Italian ammunition inconsistency was known before the war, leaving a narrow 1939 opportunity to enforce better factory quality control.

Midget craft offered Italy a practical niche weapon, while wholesale replacement of senior admirals was judged politically impossible.

Joint reconnaissance squadrons and naval observers offer a politically plausible substitute for an independent Italian naval air arm.

Continuing Scharnhorst production, later refitted with twin 15-inch turrets, could give Germany more usable battleships and simpler support.

Germany's numerous small batches of submarine types turn incremental design improvement into a support and training burden.

German cooperation with experienced Japanese carrier designers could simplify Graf Zeppelin and give surface raiders sustainable air reconnaissance.

German submarine and torpedo output needs standardised factory methods before wartime pressure forces the transition.

Oversized, slow-firing guns were hard to aim from a lively hull and gave German destroyers little advantage against faster-firing opponents.

An announced Japanese 18-inch battleship program could provoke Hitler to reconsider Bismarck and Tirpitz while exposing limits in claims about their supremacy.

An enlarged Mowe-class torpedo boat with fewer weapons and more ASW equipment becomes a mass-produced escort for German surface forces.

Continuous refinement of proven German ships could produce a larger fleet and force Britain to accelerate battleship and carrier programs.

The Royal Navy's pre-radar expectation that carriers would be hit leads into a contrast between the battle-oriented Illustrious class, strike-focused Ark Royal, and Implacable's blended design.

The video closes by asking viewers which January 1939 reforms they would choose without relying on knowledge of the coming war.
