Time notes
- 16:55QuestionHow effectively could smaller navies' coastal defence ships switch to ocean trade escort duties after going into exile?AnswerQ&A
Their coastal hull forms would usually make open-ocean escort work difficult.
- 19:26QuestionIf Germany had retained three Nassau-class battleships instead of pre-dreadnoughts, what might it have done with them?AnswerQ&A
They would probably receive new engines. Diesel propulsion and a rearranged main battery, potentially three triple turrets, are possible options.
- 21:11Overage ships and the twenty-year thresholdNotable Point
Under the interpretation offered here, ships could remain in service beyond twenty years without counting against permitted strength.
- 22:22QuestionHow useful would Vanguard or a second King George V batch have been with sixteen 14-inch guns?AnswerQ&A
It would be a useful and dangerous opponent because sixteen guns provide substantial broadside weight and volume of fire.
- 25:07QuestionWhy was a Tiger-class cruiser proposal combining 6-inch Mark 24 guns and 4.5-inch guns rejected?AnswerQ&A
The guns were wanted for other uses, and the cruiser needed 6-inch armament with a clearly distinct secondary battery.
- 28:19QuestionWhich naval battle should be considered the largest in history?AnswerQ&A
The Philippine Sea is proposed for ships and area, and Jutland for a concentrated fleet battle; the choice depends on the measure.
- 29:35QuestionWhat was the last warship laid down that served with vertical triple-expansion propulsion?AnswerQ&A
Probably a Second World War frigate such as a River-class ship, although the precise ship and expansion-engine terminology remain qualified.
- 30:49QuestionHow might the Second World War and Falklands War change if Age of Sail prize-money rules remained in force?AnswerQ&A
The Falklands War might change little, while Second World War crews could have stronger incentives to capture cruisers, submarines and merchant ships.
- 33:17QuestionWhat might change if Ernest King replaced Kimmel after Pearl Harbor instead of Chester Nimitz?AnswerQ&A
The main expected differences are stronger demands for aggressive operations and resources, and a less accommodating relationship with MacArthur.
- 34:34QuestionWould Cossack's crew have taken Altmark back to Britain if prize money had been available?AnswerQ&A
Yes, in this counterfactual, the crew would have taken Altmark back to Britain.
- 35:00QuestionWhich Royal Navy submarines and captains are worth studying alongside their better-known foreign counterparts?AnswerQ&A
The 10th Submarine Flotilla at Malta, particularly its U-class boats, and Venturer are recommended starting points.
- 37:15QuestionWhat is the assessment of Japan's Aegis-equipped vessels under construction?AnswerQ&A
Their role differs from the Type 055's despite similar size. The first pair accommodates radar ordered for land use, while a possible later pair could be designed around shipboard requirements.
- 39:25QuestionWhat battleship turret arrangement is preferred for the Second World War?AnswerQ&A
Four triple turrets are preferred, with maintenance complexity the reservation about quadruple mountings.
- 40:31QuestionWhat if the Imperial Japanese Navy consistently funded radar development from 1936?AnswerQ&A
A substantial amount of radar could have entered service by 1941 if funding stayed consistent and researchers achieved roughly comparable breakthroughs.
- 41:44QuestionWhy were Kiev and Minsk selected for tourist use rather than following the same course as their sister ship?AnswerQ&A
The tentative explanation is that other uses were less viable, leaving study and tourism as practical options.
- 42:13QuestionCould a camouflaged land army lure a fleet into a deep inland port and destroy it?AnswerQ&A
Theoretically, but suspicion, reconnaissance and sailors' local contacts would make the trap difficult.
- 45:03QuestionWhat other attacks on inland navigation could have been particularly effective?AnswerQ&A
British canal mining is proposed, although aircraft often failed to place mines in the canals.
- 45:37QuestionWhy did Age of Sail ships use two watches rather than three?AnswerQ&A
Two crew divisions suited the organisation and work rhythm, with several daily watch periods and the dog watches rotating their hours.
- 49:10QuestionWas Fisher's Baltic plan an attempt to repeat Gallipoli?AnswerQ&A
No. Fisher's Baltic plan predated Gallipoli.
- 49:38QuestionHow often have brown-water forces been lured into blue water and destroyed?AnswerQ&A
More often than is usually acknowledged, in this broad assessment, which comes without examples or a count.
- 49:56QuestionWhat prevents Minsk from entering dry dock for repairs after the fire mentioned in the question?AnswerQ&A
Moving and docking a tourist ship adds expense that its owners must justify against the value of the repair.
- 50:56QuestionHow would the South China Sea situation change if the Republic of China retained Hainan?AnswerQ&A
It would gain strategic depth, but Hainan would be exposed and require continuing defence.
- 51:38QuestionHow would Warspite react if transported to the Falklands at the Argentine invasion?AnswerQ&A
Assuming the battleship, withdrawing toward Ascension to join the task group is the proposed response; isolated action would be more dangerous.
- 53:05QuestionIs Germany the only major European power never to have operated an aircraft carrier?AnswerQ&A
Technically yes, despite Germany coming close to operating a carrier on a couple of occasions.
- 53:27QuestionWhy are manufacturers reportedly leaving the Navy's jet-training programme, and where might F/A-XX lead?AnswerQ&A
The trainer's expected financial return is judged insufficient for its requirements. Boeing is separately predicted to win F/A-XX.
- 54:18QuestionAre Ada-class corvettes useful for Ukraine, or should it sell them for now?AnswerQ&A
Crewed corvettes are considered useful, and Black Sea uncrewed operations are treated cautiously as a guide to North Atlantic requirements.
- 55:15QuestionWhat would thirty proposed advanced auxiliary destroyers give the Royal Navy in April 1939?AnswerQ&A
A powerful addition for fighting other destroyers and carrying out anti-submarine work.
- 55:57Missile damage beyond the armour beltNotable Point
An armoured ship can lose its ability to fight without a missile penetrating its main armour.
- 56:20Missile attack profiles and the radar horizonNotable Point
An isolated ship's radar horizon favours a fast missile approach in this assessment, while airborne early warning prompts a preference for numerous sea skimmers.
- 57:25QuestionCould the other two Audacious carriers be completed, or the Lion battleships converted into carriers?AnswerQ&A
Additional Audacious carriers were possible, but the Lions had not advanced far enough to provide a useful conversion basis.
- 57:37QuestionWhy was the Su-27 chosen over the MiG-29 as the basis of a Soviet carrier fighter?AnswerQ&A
The Su-27's landing gear.
- 58:07QuestionWithout the First World War, when could France finish its naval programme and when would Britain become concerned?AnswerQ&A
Completion is estimated around 1923, with British concern around 1920 as Russian construction also accelerated.
- 1:07:19QuestionWhat would inactivating the Algol-class fast sealift ships mean for sealift, and should the capability be recapitalized?AnswerQ&A
Fast sealift can remain idle for years before becoming urgently necessary. No replacement fleet size or procurement timetable is specified.
- 1:09:03Naval presence and the difficulty of measuring deterrenceNotable Point
Patrolling frigates and air-defence aircraft illustrate why deterrence is difficult to measure through incidents handled.
- 1:12:15The Falklands War as an argument about deterrence costsNotable Point
A rough CVA-01 cost comparison supports the argument that weakened deterrence can produce much larger wartime costs.
- 1:14:16QuestionCould a British twin 15-inch turret take three guns of that calibre?AnswerQ&A
The calibre would probably need to fall to about 13.5 inches, and the arrangement would still be cramped.
- 1:14:48QuestionHow much speed and lower-gunport clearance would an Océan-class ship gain by losing its upper gun deck?AnswerQ&A
Only a modest rise in gunport height and perhaps around a knot of speed are suggested.
- 1:17:05Defence procurement, skilled work and exportsNotable Point
Defence procurement is examined for its contribution to domestic industry, skilled employment and exports.
- 1:20:20QuestionWhat circumstances would lead to Queen Mary and Queen Elizabeth becoming aircraft carriers?AnswerQ&A
A severe international crisis and major Royal Navy difficulties are the circumstances envisaged.
- 1:20:40QuestionHow soon might outside forces help Saudi Arabia against the Houthis?AnswerQ&A
No timetable is offered. Logistics and intelligence support are considered more likely than direct military intervention.
- 1:24:44QuestionWhich universities should someone consider for war studies besides King's College London?AnswerQ&A
Birmingham, especially Jonathan Boff, is the principal recommendation. Supervisors' availability and temperament also matter.
- 1:27:42QuestionCould a reconstruction extend Tiger and the Lion class's 9-inch belt over areas with thinner armour?AnswerQ&A
To an extent, yes, although the detailed reconstruction is left unexplored.
- 1:28:28QuestionHow much difference would 50 additional Short Sunderlands make to Coastal Command in 1940?AnswerQ&A
They could cover important passages and force the small operational U-boat force to spend more transit time submerged.
- 1:29:20QuestionDid Britain use tugboats against U-boats in coastal waters?AnswerQ&A
Available tugs and other small vessels were used, often alongside existing towing duties.
- 1:30:15QuestionWas integrated electric propulsion delayed mainly by power electronics and frequency regulation?AnswerQ&A
Power electronics and frequency regulation mattered alongside motors, circuit protection, metallurgy and compatible electrical systems.
- 1:31:47Gun availability and British auxiliary conversionsNotable Point
A converted vessel's armament depended partly on which guns were available.
- 1:32:05QuestionWhat if the West Africa Squadron received Warrior and Black Prince in 1822?AnswerQ&A
They could strengthen its operations but probably encourage an earlier international ironclad arms race.
- 1:33:23QuestionWhat would make fast ocean liners suitable as armed merchant cruisers?AnswerQ&A
Speed is attractive, but high running costs and machinery optimised for fast passages make extended patrol work an awkward fit.
- 1:37:03The military use that suits a large ocean linerNotable Point
Passenger capacity and sustained ocean-passage speed suit large liners to troop transport.
- 1:40:30QuestionHas Britain tried to identify the Unknown Warrior, and who maintains overseas military cemeteries?AnswerQ&A
The Commonwealth War Graves Commission maintains overseas graves; the participants understand the Unknown Warrior's anonymity to be deliberate.
- 1:43:01QuestionWhen might an Astute-class submarine return to service, and what is preventing availability?AnswerQ&A
The tentative estimate is a couple of months. Insufficient dry-dock capacity is identified as the immediate obstacle.
- 1:47:15QuestionWhere are Russia's dry docks, and could they help Britain's docking shortage?AnswerQ&A
Facilities exist around the Black Sea, in the Kola region and in the Far East. Their condition is questioned, and British use is ruled out.
- 1:47:47Canadian docks and nuclear certificationNotable Point
Suggested Canadian docking support raises the cost of certifying facilities for nuclear vessels.
- 1:49:15QuestionHow long does the defence investment plan run, and does it fund dry docks?AnswerQ&A
Four years, with no dry-dock funding identified in this account.
- 1:50:19Planning approval and repeated infrastructure challengesNotable Point
A proposed planning reform would limit repeated consultation after a major project receives permission.
- 1:51:20Restoring a dock for submarine decommissioningNotable Point
A dock restored for decommissioning is expected eventually to support active submarines, raising a question about maintenance priorities.
- 1:52:06QuestionHow much would Germany do to keep two retained Derfflinger-class battlecruisers useful?AnswerQ&A
Substantial work is expected, alongside close international scrutiny that would complicate the treaty system.
- 1:52:52Solar power, batteries and national energy securityChapter
A domestic-energy proposal connects distributed generation, storage and manufacturing with reduced exposure to imported energy.
- 1:56:21QuestionWould the proposed infrastructure policy support continuing railway electrification?AnswerQ&A
Yes, with domestic generation intended to keep goods moving during a petroleum shortage.
- 1:58:24Sonar 2087 and CAPTAS-4Notable Point
A claim of French sonar superiority prompts a comparison of British and French use of a Thales system.
- 2:01:50QuestionHow does including the shipyard change the comparison of FFG(X) submissions' anti-submarine capability?AnswerQ&A
FREMM is preferred on paper for anti-submarine capability. Including the lead yard favours the Álvaro de Bazán submission and its General Dynamics and Bath Iron Works partnership.
- 2:03:06QuestionWhy do some accounts put S-38's loss in March 1942 when it survived to be sunk as a target in 1945?AnswerQ&A
The origin of the conflicting account is unknown; mistaken identification or a copied number is suggested.
- 2:04:34QuestionWould a vertical sliding breech save horizontal space in an 8-inch or larger gun?AnswerQ&A
Any saving must be assessed alongside ammunition paths, loading machinery and permitted loading angles.
- 2:05:48QuestionCould an Abdiel-class ship receive a modern refit while keeping its top speed?AnswerQ&A
Gas turbines are tentatively suggested as a way to retain speed and improve fuel management.
- 2:06:08QuestionWas British armed merchant cruiser armament sufficient for commerce raiding?AnswerQ&A
It was sufficient against merchant vessels, but another armed merchant cruiser would be dangerous to both lightly protected ships.
- 2:07:30Could torpedoes have changed Rawalpindi's last action?Notable Point
A hypothetical torpedo armament exploits the close approach of Rawalpindi's German opponents.
- 2:08:38QuestionCould 1930s liners be built for rapid wartime carrier conversion?AnswerQ&A
Japanese practice and British lists of conversion candidates are offered as examples.
- 2:10:52QuestionWhat boats could have been used around the Yukon River delta 50,000 years ago?AnswerQ&A
Hollowed-log boats are suggested tentatively after the date is corrected from an initial reading of 5,000 years.
- 2:12:41QuestionHow many commercial vessels could one modern general-purpose frigate escort?AnswerQ&A
About a dozen is suggested, preferably with uncrewed support; two crewed escorts are favoured.
- 2:13:37QuestionWhen did expected design life become a factor in naval ship design?AnswerQ&A
At least by the seventeenth century, with modern overage terminology associated with the nineteenth.
- 2:14:31QuestionWere any ships built faster than the Abdiel class and able to break 40 knots?AnswerQ&A
American nuclear carriers are suggested as very fast ships, without a confirmed maximum speed.
- 2:14:47QuestionWould Japan's new Aegis ships receive province or mountain names?AnswerQ&A
Both are considered possible, depending on classification and existing naming traditions.
- 2:17:31QuestionWhat would a Canadian Type 055-style destroyer leader look like?AnswerQ&A
A larger ship carrying more of the systems selected for Canada's Type 26-derived vessels.
- 2:18:07QuestionWhat if the United States had not moved the Pacific Fleet to Pearl Harbor?AnswerQ&A
Japan could not attack the American battle fleet at Pearl Harbor, and a carrier strike against San Diego is rejected as impractical. Its alternative plan remains uncertain.
- 2:22:18Skua, Zero and the timing of naval-aircraft comparisonsNotable Point
Aircraft comparisons depend on dates, replacement programmes and night-operating ability.
- 2:23:50QuestionDid combining torpedo and dive-bombing duties cause Barracuda's development problems?AnswerQ&A
The roles added weight and complexity, while repeated engine changes forced redesign.
- 2:25:59Assessing claims that Turkish naval guns are copiesNotable Point
The unlicensed-copy allegation is rejected on intellectual-property and engineering grounds, without a documented design history.
- 2:27:13QuestionCould the Turkish 76 mm gun copy the OTO Melara autoloader?AnswerQ&A
Copying is rejected, with performance differences cited against it. Similar breech dimensions can follow from shared calibre and ammunition requirements.
- 2:28:30QuestionWhich would usually win a gun duel between Alaska and Scharnhorst?AnswerQ&A
Alaska is tentatively favoured for a possible range advantage and more effective radar-directed fire. Both ships had radar.
- 2:30:04QuestionDid Scharnhorst switch off radar at North Cape to avoid detection?AnswerQ&A
That explanation remains unsettled. Director damage is considered, while a claim about disabling its own radar with gunfire is corrected as confusion with Bismarck.
- 2:30:58Radar performance and practice at seaNotable Point
Radar comparisons include funding, testing and crew familiarity as well as the equipment.
- 2:32:11Gun flashes and mistaken identification at North CapeNotable Point
Propellant, turret layout and Arctic visibility help explain how a cruiser could be mistaken for a battleship.
- 2:34:24QuestionWhy is indigenous development outside major European powers so often described as copying?AnswerQ&A
An unreasonable standard treats awareness of foreign designs as copying. Studying their mistakes differs from basing an entire weapon on another design.
- 2:36:09QuestionWhy did Russia not procure MiG-29Ks to replace Su-33s at the same time as India?AnswerQ&A
Russia lacked the budget to procure the replacement at the same time as India.
- 2:36:45QuestionDo copying accusations reflect a belief that some countries monopolise good ideas?AnswerQ&A
Sometimes, but a documented lineage is also mistaken for proof that all comparable weapons are copies.
- 2:37:41QuestionDoes three-inch gun ancestry extend back to twelve-pounder smoothbores such as the Napoleon?AnswerQ&A
Yes, though no detailed sequence of designs is established.
- 2:37:59QuestionDoes OTO Melara have Vickers ancestry, and where did OTO's name come from?AnswerQ&A
Yes. A Vickers joint venture became Vickers-Terni, and the 1929 Odero-Terni-Orlando name supplied the abbreviation OTO.
- 2:39:15Vickers connections across the arms industryNotable Point
Possible Rheinmetall, Remington and Springfield connections show the breadth attributed to Vickers' industrial network.
- 2:40:35Protecting industrial plans and assets from Nazi controlNotable Point
Accounts of Škoda weapon plans and Rothschild industrial interests describe attempts to keep assets beyond Nazi control.
- 2:41:52QuestionWas Vickers a subcontractor on the Manhattan Project?AnswerQ&A
Direct subcontracting is uncertain. Participants recall possible connections through Tube Alloys, enrichment research and ignition-system work.
- 2:42:52QuestionWhat if France in 1750 used Océan first rates, Téméraire third rates and Concorde frigates?AnswerQ&A
Improved designs would not solve the officer problem in this assessment, and the Royal Navy might gain better prizes.
- 2:44:33Foreign industrial assistance at KureNotable Point
French engineering and later Vickers advice connect Kure's growth with overseas shipbuilding and industrial expertise.
- 2:45:16QuestionWas Vickers a Mitsubishi Heavy Industries subsidiary?AnswerQ&A
No. Vickers had a strategic partnership with Mitsubishi predecessor organisations, dated here to 1905.
- 2:46:27What states could buy from Vickers and ArmstrongChapter
States could buy industrial infrastructure and military equipment through Vickers, Armstrong and their subsidiaries.
- 2:48:58Vickers export offers to Iran, Russia and TibetNotable Point
Recalled Vickers offers range across Iranian battleships, Russian industrial reconstruction and Tibetan artillery.
- 2:50:29Arms merchants supplying opposing customersNotable Point
Recalled sales to opposing customers connect arms commerce with Greek independence, Italian unification and later conflicts.
- 2:53:03QuestionHow much control did the Foreign Office have over Vickers-Armstrongs exports?AnswerQ&A
Control was limited in the recalled account. British operations faced restrictions over Rhodesia, while participants believe overseas branches continued supplying it.
- 2:54:31QuestionHow powerful could Vickers-Armstrongs become if it stayed intact?AnswerQ&A
The scenario envisages a large industrial group retaining shipbuilding and English Electric interests, with further acquisitions extending its reach into computing and telecommunications.
- 2:56:02Government resistance to further Vickers expansionNotable Point
Recalled resistance to further Vickers purchases centres on government concern about concentrated industrial power.
- 2:57:58Arms manufacture, capital and the East India CompanyNotable Point
Proposed East India Company connections link early arms manufacture with capital, cannon demand and imperial commerce.
- 2:59:39QuestionWhat if Ticonderoga production continued until 2008?AnswerQ&A
Probably a Flight III equivalent, with improved equipment and increasingly crowded ships comparable to later Arleigh Burke development.
- 3:01:01QuestionWere serious King George V-class refits planned?AnswerQ&A
Yes, but none of the major refits were seriously carried out.
- 3:02:08QuestionWere high-speed subcalibre shells considered for greater naval-gun range or penetration?AnswerQ&A
Yes. Recurring investigations had to weigh the smaller shell's destructive effect and whether fire control could use its extra range.
- 3:03:44An experimental eight-inch gun for extreme rangeNotable Point
A recalled 1918 eight-inch experiment pursued extreme range using a Vickers gun originally intended for Russia.
- 3:04:34QuestionWould faster subcalibre shells help against manoeuvring targets at shorter ranges?AnswerQ&A
Shorter flight time could improve hit probability, but no firm crossover point is established.
- 3:09:30QuestionHow difficult was integrating exiled navies with different ammunition, boilers and languages?AnswerQ&A
Existing language skills and translators helped, while supply adaptation, gun replacement and practical machinery repair addressed equipment differences.
- 3:12:52QuestionWhy did Goodall record a setback for battleship advocates in February 1944, and did Churchill and Cunningham influence it?AnswerQ&A
Churchill and Cunningham's influence was accompanied by pressure to provide enough carriers for Pacific operations and a possible invasion of Japan.
- 3:15:41QuestionWas there a plan to put British armoured carriers between Japan and the American carriers?AnswerQ&A
Yes. The recalled proposal placed British carriers where kamikazes would encounter them first, with an estimated 12-to-18-hour benefit for the American carriers.
- 3:16:40Carrier armour, air groups and treaty tonnageNotable Point
Limited treaty tonnage forced navies to balance carrier numbers, armour and aircraft capacity according to their expected operating areas.
- 3:19:06Later large carrier designs convergeNotable Point
Malta and Midway illustrate the ability to combine large air groups and substantial flight-deck armour beyond earlier treaty limits.
- 3:20:16Heavy piston aircraft and flight-deck strengthNotable Point
Loaded aircraft weights pressured flight-deck design before jets became the dominant concern.
- 3:20:58QuestionDid jet-engine heat end the use of wooden flight decks?AnswerQ&A
Pressure to abandon wood came earlier, through aircraft weight and fire concerns in British wartime practice.
- 3:21:50QuestionWhat if Tiger exploded during the First World War in a way comparable to Mutsu?AnswerQ&A
Accelerated Admiral-class construction is suggested, with several completions putting pressure on the postwar treaty settlement.
- 3:24:24QuestionAre certification hurdles too high for a private UK nuclear-submarine dry dock?AnswerQ&A
Yes, particularly given the time available to provide the submarine facilities.
- 3:24:36QuestionWhich post-1890 battleship or battlecruiser might be compared with Vasa for poor design?AnswerQ&A
A design allegedly revised until too heavy to float is offered tentatively, but its name remains unclear.
- 3:25:41QuestionHow much could modern construction improve older gun weapons retained by fictional shipgirl factions?AnswerQ&A
Lighter structures could reduce topweight and improve traverse, while larger gains require machinery changes and the fiction need not obey ordinary engineering.
- 3:30:04QuestionHow effective would a Cadorna-sized destroyer be with four triple or quadruple rapid-firing, high-velocity 5.5-inch dual-purpose mountings?AnswerQ&A
It would be an unnecessarily complicated light cruiser, with crowded loading arrangements and hull dimensions working against the dense armament.
- 3:34:28QuestionWhat could merchant-cruiser and boarding-ship characters do in peacetime, and which type would suit it best?AnswerQ&A
Merchant-derived types could return to commercial work, while warship types could perform continuing peacetime naval duties.
- 3:36:37QuestionWhat if Marines used four 6-inch batteries to sink a Japanese cruiser at Guadalcanal?AnswerQ&A
Japan would lose another cruiser, while the Marine unit would probably become famous and inspire a film.
- 3:37:51Defence bureaucracy and the appearance of capabilityNotable Point
A remembered meeting distinguishes the appearance of protection from the ability to provide it.
- 3:39:15QuestionWhy might commanders avoid using field artillery against ships?AnswerQ&A
Firing reveals the battery, and ships are judged generally favoured in the exchange.
- 3:39:52Civilian observers and the limits of secrecyNotable Point
Satellite and online-investigation anecdotes illustrate what civilians can infer from visible clues and affordable equipment.
- 3:43:48QuestionShould navies replace frigate and destroyer labels with aircraft-style capability letters?AnswerQ&A
The existing labels already convey roles within each navy's system. Capability letters would become unwieldy, and aircraft designations also vary between countries.
- 3:49:07QuestionDid a Strike Eagle destroy a helicopter with a laser-guided bomb in the Gulf War?AnswerQ&A
Yes, a Gulf War helicopter kill with a laser-guided bomb is recalled.
- 3:49:29QuestionWhich cruisers or larger ships survived a main-magazine explosion without sinking?AnswerQ&A
Boise and New Orleans are the examples eventually offered, following uncertainty about the date restriction and what counts as surviving without sinking.
- 4:03:23Sea Lion's landing barges and Dover's defencesNotable Point
Sea Lion's proposed barge landings face tidal delays, exposed unloading and fortified ports before the invaders can establish an army ashore.
- 4:07:54QuestionHow did the British government obtain the money to break up Vickers?AnswerQ&A
In this account, legal powers and debt made breakup possible after wartime losses had weakened the company.
- 4:10:22QuestionCan you name an invention tested in a shed or in the middle of a bog?AnswerQ&A
The Petroleum Warfare Department's fuel-on-water experiments are recalled, with the test setting uncertain between bogs and very muddy lakes.
- 4:11:19QuestionHow would you refit a Tillman II or IV in 1925 to improve accuracy and rate of fire while retaining four six-gun turrets?AnswerQ&A
Fire each six-gun turret in groups of three or divide it into two triple arrangements. The proposed loading improvements become easier only if the requirement to retain every gun is relaxed.
- 4:14:22QuestionWhat resource would help with naval architecture, especially drag as a function of speed?AnswerQ&A
The recommended starting point is A Short History of Naval and Marine Engineering by Edgar C. Smith.
- 4:15:17QuestionIf the Malta-class carriers had been built, would they have needed several bases, such as Liverpool and one in southern England?AnswerQ&A
Probably: a fleet on that scale is expected to require a correspondingly larger basing system.
- 4:18:15QuestionAre there terrible ships that you nevertheless like?AnswerQ&A
Personal favourites include ambitious early American battleships, French designs, Graf Zeppelin, Yubari and American cruisers, with affection for their appearance or ingenuity surviving criticism of their performance.
- 4:21:45Sea Control Ships and names based on intended rolesNotable Point
A disagreement over small Sea Control Ships leads into criticism of labels that describe an intended mission more clearly than a ship's type.
- 4:23:01QuestionHow tough would an R-class battleship be if filled with cork for anti-invasion service?AnswerQ&A
A substantial amount of cork could be fitted and would affect torpedo damage, but no estimate of the protection is given.
- 4:24:15QuestionWhat if the Royal Navy in 1750 replaced its first rates with Victory, second rates with London-class ships, third rates with Africa and frigates with Constitution-type ships?AnswerQ&A
The first and second rates would fare well and the frigates would become very powerful, though Africa-type third rates would be comparatively light in firepower and the expense would be substantial.
- 4:25:07QuestionWhat would the world do if the Suez Canal became impassable because of radiation?AnswerQ&A
Ships would sail around Africa, and ship designs would probably adapt to that route. Whether the canal could be cleaned up remains open.
- 4:26:00QuestionWhat if Russia built the logistics and infrastructure for invasions of Japan, China and India in the late 1890s?AnswerQ&A
Britain and Japan would draw much closer in opposition, and American interests in China could bring the United States into that grouping.
- 4:27:03Historical films, compressed campaigns and coalition warfareNotable Point
Compressed timelines and a national focus can obscure long campaigns and multinational operations in historical films.
- 4:30:05QuestionWhat if Russia supported China in the 1890s to preserve the dynasty and build an army strong enough to resist partition?AnswerQ&A
Russia's resources are doubtful, and military strength would require fiscal and political reforms that outside funding alone could not supply.
- 4:32:01QuestionWhat would balanced fleets for the major powers look like before the First World War?AnswerQ&A
Most major fleets are judged fairly balanced. Germany's weak cruiser force and American gaps in destroyer and later cruiser procurement are the main exceptions.
