Subcalibre shells, range and fire-control limits
Smaller, faster shells trade destructive effect for velocity, while fire-control reach limits the value of extra range.

An experimental eight-inch gun for extreme range
A recalled 1918 eight-inch experiment pursued extreme range using a Vickers gun originally intended for Russia.
Faster shells and shorter-range hit probability
Shorter flight time could improve hit probability, but no firm crossover point is established.
Integrating Polish, Dutch and Free French ships
Existing language skills and translators helped, while supply adaptation, gun replacement and practical machinery repair addressed equipment differences.
Goodall's battleship setback and carrier demand for Japan
Pacific carrier demand and the need to sustain air support during a possible invasion of Japan help explain the setback for battleship advocates.
Positioning armoured carriers to absorb attacks off Japan
Putting British armoured carriers nearest Japan was expected to divert attacks and give American carriers another 12 to 18 hours.
Carrier armour, air groups and treaty tonnage
Limited treaty tonnage forced navies to balance carrier numbers, armour and aircraft capacity according to their expected operating areas.
Later large carrier designs converge
Malta and Midway illustrate the ability to combine large air groups and substantial flight-deck armour beyond earlier treaty limits.
Heavy piston aircraft and flight-deck strength
Loaded aircraft weights pressured flight-deck design before jets became the dominant concern.
Wooden flight decks, fire and jet exhaust
Aircraft weight and fire risk put pressure on wooden flight decks before jet exhaust became a concern.
If Tiger exploded during the First World War
Accelerated Admiral-class construction is suggested, with several completions putting pressure on the postwar treaty settlement.
Certification for a private submarine dry dock
Nuclear certification is judged too demanding for a private venture to fill the submarine dry-dock shortage within the available time.
A later counterpart to Vasa's design failure
A design allegedly revised until too heavy to float is offered tentatively, but its name remains unclear.
Modern construction for gun-armed shipgirls
Lighter structures could reduce topweight and improve traverse, while larger gains require machinery changes and the fiction need not obey ordinary engineering.
A Cadorna-sized destroyer with multiple 5.5-inch guns
Loading arrangements make four triple or quadruple 5.5-inch mountings an awkward choice for a ship already in light-cruiser territory.
Peacetime roles for merchant shipgirls
Merchant-derived types could return to commercial work, while warship types could perform continuing peacetime naval duties.
Marine artillery sinking a cruiser at Guadalcanal
The hypothetical sinking adds one Japanese cruiser loss and a celebrated Marine unit, with little wider effect on the war.
Defence bureaucracy and the appearance of capability
A remembered meeting distinguishes the appearance of protection from the ability to provide it.
Why field artillery might avoid engaging ships
Firing reveals the battery, and ships are judged generally favoured in the exchange.
Civilian observers and the limits of secrecy
Satellite and online-investigation anecdotes illustrate what civilians can infer from visible clues and affordable equipment.
Frigates, destroyers and aircraft-style role designations
Frigate and destroyer labels convey intended roles, while listing every overlapping capability would produce long strings of letters.
A Strike Eagle's helicopter kill with a bomb
A recalled Gulf War helicopter kill by laser-guided bomb supplies an unusual example of a Strike Eagle air-to-air success.
Cruisers surviving main-magazine explosions
Boise and New Orleans are offered as examples of surviving magazine explosions, after separating survival afloat from later salvage.
Sea Lion's landing barges and Dover's defences
Sea Lion's proposed barge landings face tidal delays, exposed unloading and fortified ports before the invaders can establish an army ashore.
Vickers' breakup, debt and wartime asset losses
Vickers' debt and wartime asset losses reduced its ability to resist legal and financial pressure.
Testing burning fuel on water
The Petroleum Warfare Department's coastal fire experiments are recalled as having used bogs or very muddy lakes.
Refitting Tillman battleships while retaining six-gun turrets
A Tillman refit thought experiment weighs firing in groups of three against the space needed for improved loading machinery.
A reading recommendation for naval engineering and drag
Edgar C. Smith's history of naval and marine engineering is recommended in response to a question about drag and speed.
Basing a hypothetical Malta-class carrier fleet
A short Malta-class counterfactual links a larger carrier fleet with the need for several bases.
Why flawed warships can still be interesting
Personal favourites include ships with weak industrial foundations, ambitious gun arrangements and attractive designs with operational limitations.
Sea Control Ships and names based on intended roles
A disagreement over small Sea Control Ships leads into criticism of labels that describe an intended mission more clearly than a ship's type.
Cork filling for an R-class battleship
A short anti-invasion thought experiment considers adding cork to an R-class battleship.
Giving the Royal Navy later warship designs in 1750
A fleet replacement counterfactual gives Britain powerful frigates while exposing uneven changes in firepower and cost across the rating system.
Shipping routes if radiation closes the Suez Canal
A Suez closure thought experiment links diversion around Africa with changing ship requirements and the wider consequences of radioactive contamination.
Russian invasion preparations and an Anglo-Japanese response
Russian preparations for expansion in Asia are assessed through the diplomatic opposition they could bring together.
Historical films, compressed campaigns and coalition warfare
Compressed timelines and a national focus can obscure long campaigns and multinational operations in historical films.
Could Russian support have stabilised Qing China?
A Russian-backed Qing recovery is examined through the dependence of armies, taxation and reform on one another.
German and American fleet imbalances before the First World War
Capital-ship investment is compared with the cruisers and destroyers needed to make a fleet useful across its missions.
The French Navy's worldwide base network
French bases in North Africa, the Atlantic and the Far East gave the Allies reach beyond the fleet itself.
French and Italian fleets in the treaty era
France and Italy fielded broadly comparable fleets, but French deployment was global while Italy concentrated in the Mediterranean.
How neglected dry docks reduce fleet availability
Delayed investment in dry docks can create maintenance backlogs that leave ships and submarines unavailable.
French infrastructure and Mediterranean operations
North African repair facilities and nearby airfields could sustain Allied ships and convoys in the Mediterranean.
Dunkerque, Strasbourg and Béarn at Brest
The Brest force combined fast capital ships, cruisers, destroyers and the limited but useful carrier Béarn.
Older French battleships as convoy escorts
Provence, Bretagne and Lorraine could deter raiders despite being outmatched by modern fast battleships.
Why a convoy escort should resist a raider's decoy
A Revenge-class battleship could protect its convoy by refusing to chase one German raider while the other approached the merchant ships.
Béarn as an Atlantic convoy escort
Atlantic convoy escort and raider searches offered Béarn useful work away from concentrated enemy air power.
French fast capital ships and Allied naval strategy
French fast capital ships complemented a Royal Navy fleet with many slower battleships.
French escorts and submarines across several seas
Destroyers, sloops, minelayers and submarines supported imperial routes, coastal waters and Allied convoys.
