Five Weaknesses of Allied/Axis/Minor Navies in 1939 & 1940; Response to some Comments

Fleet planners in 1939 could not assume that wartime aircraft and carrier doctrine would eclipse useful capital ships.

They would probably delay the battle until the British could concentrate a stronger screened force.

Not at the level of a mature fleet carrier, but enough for reconnaissance, limited air defense, and strategic pressure on British deployments.

Probably not; Chamberlain relied on Churchill politically, and Churchill had wide latitude over Admiralty decisions.

British construction is plausible, but either choice still depends on scarce experienced Dutch officers.

A postwar Norwegian assessment suggests modest air readiness could have inflicted severe losses on German transports beyond fighter cover.

A carrier was possible only with a much earlier start, but it might also have influenced German carrier development.

A Wichita-influenced eight-inch cruiser would offer prestige, practical capability, and deterrent value.

Yes, if it can keep those reservists trained; modern simulation makes that increasingly affordable.

Only with a much earlier start; the video's 1939-40 intervention window is too late for that scale of infrastructure.

Not simply; the change would require a third shaft and conflict with the treaty-driven design choices behind the ship.

German surface ships could impose disproportionate costs by forcing Britain to reroute convoys and assemble powerful hunting groups.

The Treaty of Versailles left Germany without the industrial and personnel depth needed to create a fleet capable of defeating Britain on a 1939 timetable.

Britain had enough active or readily reopened large slips to accommodate four Dutch ships.

Yes, provided the proposed operation is genuinely achievable rather than physically impossible.

That can be useful, but without a fixed boundary the answer can keep moving decades earlier and make the exercise unmanageably broad.

Japan's navy was already providing air support and fleet operations in China before the wider Pacific War.

Launch-to-commission dates show how wartime labor disruption delayed British carriers that were already substantially assembled.

A brief correction places the misleadingly named American shipbuilder in New Jersey, directly across the river from Philadelphia.

The mine-warfare concept is strong, but simpler minelayers would deliver more useful hulls for the available industry.

Yes - pause some battleships to accelerate carriers and escorts, while prioritizing a faster capital ship such as Vanguard.

Australia had plans for docks capable of handling carriers and battleships, but slow reclamation delayed their wartime value until 1945.

Yes, and a practical response would be more Dunkerque-sized hulls using British-supplied or licensed heavy guns.

Yes; corrected torpedoes might not be ready in December 1941, but could improve early 1942 submarine operations substantially.

The concept is sound, but interservice politics and limited access to German aircraft make it improbable in 1939-40.

Yes; British crews explored torpedoes, shells, and swimmer-placed depth charges, with mixed results.

Probably not; Britain could build asymmetrically around fast G3s, heavy N3s, and global bases instead of matching Tillmans ship for ship.

The closing exercise asks viewers to design the best aircraft carrier possible with technology and knowledge available in 1939.
