A short-war force facing a longer conflict
Japan's limited industrial depth encouraged short-war planning and left its forces struggling to adapt to a longer conflict.

Type C and the use of prefabrication to expand output
Prefabricating escort components outside the yard increased throughput without requiring rapid expansion of Japan's shipyard industry.
From Kaibōkan: The Imperial Japanese Navy Corvettes of WWII ·
Type C's basic convoy escort specification
Type C accepts a basic, standardised design with substantial depth-charge armament, modest speed and diesel endurance.
From Kaibōkan: The Imperial Japanese Navy Corvettes of WWII ·
Five-month Type C builds and the cost of ordering late
The first Type C's September 1943 to February 1944 build illustrates rapid assembly, followed by the argument that such ships were needed years earlier.

A counterfactual programme of convertible fishing boats
A colleague's exercise imagines Japan funding deep-sea fishing boats from 1934 with designs suitable for rapid wartime conversion.

Type C submarine successes and the Bonefish example
Growler, Trigger and Bonefish are cited as successes involving Type C escorts, with Bonefish introducing the value of several ships working together.
From Kaibōkan: The Imperial Japanese Navy Corvettes of WWII ·
Why depth-charge attacks needed several ships
One ship can maintain contact while others make depth-charge runs, overcoming the gap when an attacking escort loses its own contact.
From Kaibōkan: The Imperial Japanese Navy Corvettes of WWII ·
Type D's speed and the limits of fleet escort
Type D's modest speed increase is judged insufficient for fleet escort, particularly without effective fire control.
From Kaibōkan: The Imperial Japanese Navy Corvettes of WWII ·
Type D's claimed successes, losses and late programme
An attributed submarine success is weighed against the class's losses, late construction and inability to support rapid fleet manoeuvre.

Planned ships, completed ships and repeat frigate orders
The comparison of 187 Japanese completions with British Empire totals shows how repeat orders can complicate planned-versus-built figures.
From Kaibōkan: The Imperial Japanese Navy Corvettes of WWII ·
Recognising the escort problem without solving it in time
Japan recognised the escort requirement and developed useful ships, yet failed to deliver enough of them before the operational need became acute.
From Kaibōkan: The Imperial Japanese Navy Corvettes of WWII ·
No. 1's loss and the air-cover requirement of small escorts
No. 1's loss to aircraft illustrates small anti-submarine escorts' dependence on air cover or support from heavier ships.
From Kaibōkan: The Imperial Japanese Navy Corvettes of WWII ·
A larger escort force and the Mark 14 counterfactual
The suggestion of 500 available escorts raises an unresolved question about American submarine losses and earlier recognition of torpedo defects.
From Kaibōkan: The Imperial Japanese Navy Corvettes of WWII ·
Industrial standing and unused fishing-vessel conversions
Japan's substantial prewar naval industry makes the small escort output a question of choices as well as absolute industrial limits.
From Kaibōkan: The Imperial Japanese Navy Corvettes of WWII ·
Armed trawlers as useful additions to an escort group
An armed trawler without sonar could still make a depth-charge run directed by a ship holding contact.

Lasers, guns and the risk of waiting for a complete solution
A modern laser-versus-gun analogy extends the argument that waiting for an ideal system can leave ships without an adequate available defence.

How a subsidised fishing fleet could prepare escort conversions
A hypothetical fleet of about 600 fishing vessels combines two subsidised designs with stockpiled equipment and yards outside normal naval construction.

What if small-ship prefabrication had been retained after 1945?
The closing prompt asks how retaining mass-production skills for ships of 1,000 tons or less would have affected the Cold War and later navies.

VLS cell counts and assumptions of Western dominance
A criticism of modern frigate design links VLS cell counts and defensive layers to the belief that Western technological superiority would allow navies to choose their fights.

Italian gun calibres and the case for layered defence
Missiles, 5-inch guns, 76 mm guns and 25 mm weapons illustrate how an Italian armament arrangement supplies several ways to engage threats at different ranges.

Fore-and-aft weapon arcs after a system failure
Overlapping firing arcs let fore-and-aft mounts retain coverage after one fails; weapons on opposite sides can leave an unsupported sector.
From Products of Their Time: VLS vs Gun sighting in ship design ·
VLS missile coverage and the firing arcs of guns and lasers
Missiles that turn after launch encourage assumptions of all-round coverage, while guns and prospective laser weapons still need suitable positions and clear firing arcs.

Placing line-of-sight weapons before self-orienting missiles
A proposed design sequence places weapons that need a direct line of sight first, then fits missiles that can change direction after an unobstructed launch.
