Time notes
- 12:29QuestionWhat if every R-class battleship received Royal Oak's prewar modernization?AnswerQ&A
Their employment and the overall war would change little, but improved fire control and anti-aircraft capability would make them much more lethal in individual engagements.
- 19:25QuestionHow would eight-inch proximity-fuzed shells for County-class cruisers have affected the war?AnswerQ&A
They could break up and damage air formations at unusually long range, although they probably would not save Dorsetshire and Cornwall.
- 21:38QuestionDid icing help explain why escort carriers were uncommon on Arctic convoys?AnswerQ&A
Yes; icing, frozen machinery, lack of deck storage, poor flying conditions, and violent ship motion all made small-carrier operations difficult.
- 24:26QuestionWhat happened to the new North Korean warship during launch, and why did it sink?AnswerQ&A
The stern appears to have snagged during a sideways launch while the bow kept moving, causing the ship to roll and sustain damage.
- 27:04QuestionWas USS Scorpion probably lost to a battery explosion?AnswerQ&A
A battery explosion is judged the most likely explanation, but the available evidence does not establish the cause.
- 27:45Why North Korea is investing in larger surface combatantsNotable Point
Possible roles for North Korea's larger combatants include extending offshore protection, supporting missile submarines, and resisting amphibious attack.
- 32:45What North Korea's new combatant may carry, and what remains unknownNotable Point
A dense advertised weapon fit sits on a compact hull whose missile packing, propulsion, range, and real performance were still unproven.
- 39:20QuestionCould the larger launch tubes be intended for hypersonic missiles that Russia might supply?AnswerQ&A
Possibly, but the idea remains speculative and could reflect an aspiration rather than an available capability.
- 39:57QuestionCould the next generation of Royal Navy offshore patrol vessels be upgraded with a 4.5-inch gun?AnswerQ&A
The objection is budgetary: a frigate-like fit risks having patrol ships counted against the frigate force, while lighter guns are considered a possible upgrade.
- 43:26QuestionWhat if Congress ordered the US Navy to move directly from twelve-inch to fifteen-inch guns?AnswerQ&A
The new caliber would delay American ships and provoke a wider gun-caliber competition rather than a simple like-for-like British response.
- 45:14How a 16.5-inch gun could change the Queen Elizabeth designNotable Point
A heavier gun could bring a longer hull and more machinery, while barrel wear and the timing of small-tube boilers would influence the design.
- 49:14QuestionCould Germany respond effectively if the American and British battleship programmes moved to larger guns?AnswerQ&A
Obtaining help from Austria-Hungary is suggested as the quickest route, but an unlikely choice. Domestic development would be slow and expensive enough to end Germany's competitive involvement in the race.
- 50:06QuestionCould money saved from the battleship race expand Germany's cruiser and destroyer forces before the First World War?AnswerQ&A
Possibly, but the lighter forces would lack the competitive heavy ships around which they were expected to operate.
- 51:08QuestionWould Agincourt have been built with 18-inch guns in this larger-calibre battleship race?AnswerQ&A
That depends on the next American step. The historical proposal is also disputed, with three twin 18-inch turrets and four triple 15-inch turrets offered as competing reconstructions.
- 54:46QuestionWhat would Yamato look like if the earlier gun race had produced British 18-inch battleships?AnswerQ&A
The treaty system and subsequent building programmes would change so extensively that Yamato would be a fundamentally different design.
- 58:10QuestionIs Ben Wilson's Empire of the Deep worth reading?AnswerQ&A
Yes, with reservations about some judgments and recognition that a broad naval history cannot cover everything.
- 1:00:27QuestionWhy is the British Union Flag commonly called the Union Jack?AnswerQ&A
Its close association with Royal Navy use at the jack staff made Union Jack the familiar popular name, even though Union Flag is the formal term.
- 1:05:57QuestionHow late could Nelson and Rodney be redesigned for 28 knots if Italy laid down new Caracciolo-class ships?AnswerQ&A
The design could theoretically be lengthened and given more machinery, but an early Italian challenge might instead justify extra F3-type ships. A later treaty-compliant Italian programme would come after Nelson and Rodney were already too far advanced.
- 1:10:02QuestionWould the Americans or Japanese demand modern replacement ships as compensation for additional British construction?AnswerQ&A
They might ask, but the projected outcomes differ. American funding remains uncertain, Japan's claim is judged weaker, and France would have a direct need to respond to Italy.
- 1:11:49QuestionWas the tendency to make only minimal dockyard expansions a problem of France's national yards or the whole industry?AnswerQ&A
The assessment applies to the whole French shipbuilding industry.
- 1:14:59QuestionWhat capabilities and classification fit North Korea's new destroyer class?AnswerQ&A
Its capabilities need to be judged in operation. Frigate, or possibly corvette, is proposed as a better description of its range and intended role.
- 1:19:04QuestionHow would the loss of HMS Lion to a magazine explosion at Jutland affect the Royal Navy and Beatty's legacy?AnswerQ&A
Beatty would become a heroic martyr, replacement ships would gain urgency, and Royal Navy leadership and postwar treaty policy could develop differently.
- 1:25:24QuestionCould a helicopter deploy and a ship recover an uncrewed underwater vehicle for anti-submarine and mine warfare?AnswerQ&A
Yes, a vehicle of roughly torpedo size is considered plausible. The difficult part is safely recovering it after operations involving explosives in salt water.
- 1:29:07Why freely drifting mines threaten friendly shipping tooNotable Point
Mines that escape their moorings can spread beyond the intended area and threaten friendly ports and fishing vessels.
- 1:36:21QuestionIs Harland and Wolff the closest historical equivalent to the proposed Port Alpha shipyard?AnswerQ&A
It is a massive automation-led response to labor shortages, and the purpose-built Kaiser yards are a closer historical analogy than Harland and Wolff.
- 1:39:26QuestionAre anti-submarine torpedo tubes fired all at once or one weapon at a time?AnswerQ&A
Usually one at a time during a controlled prosecution, but a ship under attack or engaging at long range may fire multiple weapons, often with a short interval.
- 1:42:33QuestionWhat if Tiger survived the London treaty, was rebuilt, and accompanied Hood at Denmark Strait?AnswerQ&A
Tiger's survival could free Hood for a major refit and strengthen the wider fast-capital-ship force, changing both the battle and the pursuit of Bismarck.
- 1:46:55QuestionWhy was Iron Duke retained as the training ship instead of Tiger?AnswerQ&A
Chatfield favored Iron Duke's gunnery associations and stability as a training platform, even though Tiger offered greater potential for a later combat reconstruction.
- 1:52:12QuestionWhy was the pre-dreadnought HMS Hood never raised for scrap after the world wars?AnswerQ&A
The cost of raising and dismantling the wreck outweighed the likely benefit.
- 1:57:53QuestionWhat if Little Boy or Fat Man suddenly produced a Tsar Bomba-scale yield after release?AnswerQ&A
The target would be devastated on a vastly greater scale, the B-29 would probably be lost, and the unexplained yield difference would complicate assessment of both attacks.
- 1:59:52QuestionWhat was the largest calibre used in a quintuple or larger gun mount?AnswerQ&A
The tentative answer is 40 mm, after excluding grouped recoilless rifles and Gatling-type barrels from the definition.
- 2:01:37QuestionHow did the design philosophy of Fletcher and Gearing destroyers differ from Tribal and Battle-class destroyers?AnswerQ&A
The American ships remained centered on fleet torpedo attack, whereas the British types prioritized guns for fighting and clearing enemy destroyers.
- 2:03:31QuestionWas the Somers class still focused on torpedoes despite carrying four twin 5-inch mounts?AnswerQ&A
Yes. Its layout still gave torpedoes priority, despite a gun battery that made it unusually heavily armed for a destroyer.
- 2:05:59QuestionWhy was it normal for some World War II troopships to travel by themselves?AnswerQ&A
The fastest liners could outrun a submarine's attempt to reach an attack position; slower troopships normally sailed in fast convoys.
- 2:07:47Why warships struggled to escort the fastest linersNotable Point
A liner could sustain more than thirty knots across an ocean, while a warship designed to cruise slowly and sprint for battle could damage its machinery trying to match that schedule.
- 2:11:21QuestionWhat may have caused the Mexican ship Cuauhtémoc to strike the Brooklyn Bridge?AnswerQ&A
A variable-pitch propeller failure or fouling is plausible, but the accident report is needed before drawing a conclusion.
- 2:14:07Why U-864's cargo would not transform Japan's warNotable Point
Technical data and small quantities of special material could support Japanese prototypes, but they could not replace the industrial capacity and resources needed for strategic effect.
- 2:17:57QuestionIs it too early to assess the legacy of the Italian Maestrale-class frigates?AnswerQ&A
A final verdict is premature, but their all-round frigate role offers a possible connection with the succeeding Bergamini FREMM family.
- 2:20:47Sustained liner speed, trials and emergency powerNotable Point
Liners had different sustained, trial and emergency speeds, with fuel economy and machinery life determining which could be used routinely.
- 2:25:37QuestionIf Britain gained Alaska after the Crimean War, where would the Royal Navy build bases and what fleet would they support?AnswerQ&A
Geography would point to familiar Alaskan base locations, but the fleet would likely be modest and largely shaped by Canadian investment.
- 2:27:27QuestionDid Germany know D-Day was coming, and did it have spies in Britain?AnswerQ&A
Germany expected an invasion, but Allied control of its British agent network helped deceive it about when and where the attack would fall.
- 2:28:44QuestionCould a post-1910 steamship exceed its rated top speed by ten or twenty percent without regard for damage or safety?AnswerQ&A
It could sometimes exceed normal speed temporarily, but only by consuming engineering margin and accepting close monitoring, damage, and later repair.
- 2:30:35QuestionHow would the United States react to a capital-ship-sized drydock being built at Prince Rupert, British Columbia, in 1939?AnswerQ&A
It would ask questions but probably accept an anti-Japanese explanation and seek access, because one drydock was not evidence of a threatening British fleet base.
- 2:34:31QuestionWhere would you fire one spread of torpedoes between 1900 and 1999?AnswerQ&A
Scharnhorst and Gneisenau at the outbreak of World War II are one choice, with the aim of preserving Glorious; alternatives include Bismarck's launch, the Russo-Japanese War, and Jutland.
- 2:46:30QuestionWere anti-submarine weapons ever used against ground troops, reversing the use of land-attack weapons against ships?AnswerQ&A
The Australian Matilda Hedgehog is a concrete example of adaptation for land use. Japanese depth-charge employment against landings is recalled uncertainly, and no example of torpedoes fired at troops is identified.
- 2:48:10QuestionWhy was HMS Zubian created, and what legacy did it leave?AnswerQ&A
It was an emergency expedient whose unexpected appearance reinforced German fears that Britain had secret shipyards and unknown warships.
- 2:50:11QuestionHow much could a British-Australian-Dutch command formed in 1940 under Roger Keyes disrupt Japan's moves in 1941?AnswerQ&A
It could materially improve coordination and local defenses, even if the Allies had few additional forces to commit.
- 2:51:54Dowding, Park, and jungle preparation in MalayaNotable Point
A stronger Far Eastern command could bring experienced air leaders and earlier preparation for jungle fighting, although the proposed organization remains disputed.
- 2:54:51A small carrier and regional repairs for Force ZNotable Point
Even a modest fighter detachment could matter to Force Z, while Indian repair facilities could keep useful ships within reach of the Far East.
- 2:58:02QuestionWhat if the Royal Navy persuaded a gun maker to produce pom-poms and medium naval artillery in Australia after the Munich crisis?AnswerQ&A
Regional air defense and refit capacity would improve, and Australia might build heavily armed screening cruisers while supporting more capable ships for Force Z.
- 3:01:04Australian County cruisers using eight-inch guns against aircraftNotable Point
Seventy-degree elevation allowed Australian County-class cruisers to fire their eight-inch guns at aircraft, a capability that surprised an American observer in the recalled episode.
- 3:09:20QuestionHow often did smaller ships try to ram larger ships, and did it work?AnswerQ&A
Ramming could be a last resort, and a small ship could survive a collision with a larger one. HMS Spitfire and Nassau at Jutland provide the example, but no frequency is established.
- 3:25:13QuestionWhat could an Italian-style reconstruction do for HMS Warspite?AnswerQ&A
It could create a faster, extensively rebuilt ship with three triple 15-inch turrets, while influencing later Queen Elizabeth and King George V-class choices.
- 3:29:45QuestionHow often were the casemate guns of the R and Queen Elizabeth classes actually used?AnswerQ&A
They were useful and frequently relevant in World War I, but surviving casemates saw comparatively little use in World War II.
- 3:33:24QuestionHow does North Korea's new missile destroyer compare with its contemporaries?AnswerQ&A
It is judged closer to a frigate, or arguably a corvette when its range and capabilities are considered.
- 3:34:34QuestionWhat if the World War II combatants had modern drone-control technology?AnswerQ&A
Local radio-controlled reconnaissance would be useful, and an armed anti-submarine drone is proposed; the expected Allied advantage is producing workable equipment in much larger numbers.
- 3:36:55Why advanced German weapons could lose to production and logisticsNotable Point
A disagreement over Panzer IV and Panther reliability separates problems caused by design changes from those caused by damaged industry and inadequate maintenance.
- 3:43:46QuestionHow do World War II and modern five-inch naval guns differ in power, range, fire rate, accuracy, and durability?AnswerQ&A
Modern guns are judged better across those measures because metallurgy, barrel design, explosives, and shell design have advanced substantially.
- 3:45:30A postwar Royal Navy standardized on 5.25-inch gunsNotable Point
A common 5.25-inch armament for postwar British cruisers, destroyers, and frigates raises a hypothetical question about an American response.
- 3:46:46QuestionCould HMS Pickle really have been docked, fully recoppered, and launched again on the same day in 1803?AnswerQ&A
Probably not: an assessment or limited repair fits the reported time better, while comparable complete coppering jobs took at least a week.
- 3:52:05QuestionHow useful could the former Italian carrier Giuseppe Garibaldi be to Indonesia?AnswerQ&A
It could be useful as a helicopter and anti-submarine carrier with drones, while any fixed-wing role would depend on acquiring suitable aircraft.
- 3:56:05QuestionHad the problem that led to the Hawkins class reappeared after World War I?AnswerQ&A
The comparison is rejected here because Hawkins and the Counties were conceived as large light cruisers whose later treaty classification did not change their original design role.
- 4:01:05QuestionCould aircraft controls become user-friendly enough for flying to be as common as driving?AnswerQ&A
Easier controls do not remove the consequences of failure or the difficulty of judging hazards in three dimensions.
- 4:02:14QuestionAre there photographs of County-class cruisers with their guns elevated to 70 degrees?AnswerQ&A
Yes; County-class examples are reported, along with photographs of Canarias at high elevation.
- 4:02:40QuestionWhat would a British fourth-rate ship of the line look like around 1815?AnswerQ&A
Broadly a two-deck ship of fifty to sixty guns, already losing its place in the battle lines of the major navies.
- 4:07:11QuestionHow early were studies made for converting merchant ships into escort carriers?AnswerQ&A
The lineage begins in World War I with liner conversions such as Argus and continues through the interwar period before settling into the escort-carrier role.
- 4:10:41Using D. K. Brown critically on British warship designNotable Point
Brown's technical work receives a strong recommendation alongside specific criticisms of its interwar coverage and an explicitly unverified family anecdote.
- 4:15:28QuestionWould you rather face a North Atlantic storm or a Lake Superior storm in a typical regional freighter?AnswerQ&A
The North Atlantic, because an ocean-going freighter is built to expect severe weather, while a Great Lakes ship may be less prepared for the lake's worst storms.
- 4:17:51QuestionWas the B-29 rushed into service, causing its heavy mechanical losses?AnswerQ&A
The replies disagree over the word 'rushed', but agree that the B-29 attempted a difficult technological leap while moving rapidly into mass production and service.
- 4:20:17QuestionHow effective would a third run of Dido-class cruisers be with Vanguard's improved 5.25-inch guns?AnswerQ&A
They would be useful air-defense ships, with their value rising sharply if an invasion of Japan extended the war and produced much heavier kamikaze losses.
- 4:24:01The civilian costs feared from invading or blockading JapanNotable Point
The assessment of a prolonged war includes catastrophic invasion casualties and the mass starvation expected from a sustained blockade.
- 4:26:32QuestionWould a larger surviving force of C-, D-, and E-class cruisers have allowed the Royal Navy to retire its older Arethusa and Town classes?AnswerQ&A
Yes, although the older cruisers would probably be placed in reserve rather than scrapped immediately.
- 4:29:26QuestionWhat would a modern Atlanta-style anti-aircraft cruiser look like without missiles?AnswerQ&A
Numerous Italian 76 mm mounts, supplemented by as many five-inch guns as practical.
- 4:29:51QuestionWhat is the best part of the British Isles for a secret naval base?AnswerQ&A
Anglesey is the preferred answer because of its sheltered strategic position and infrastructure, with Skye as an alternative.
- 4:35:05QuestionWhat made teak superior to English oak for some naval uses, and how did it compare with American live oak?AnswerQ&A
Teak is dense, hydrophobic, and exceptionally durable, though costly and hard on tools; its marine longevity made it especially valuable in warships.
- 4:37:14QuestionHow soon should the aging Great Lakes freighter fleet begin to be replaced?AnswerQ&A
As soon as possible, given the age of the ships and the much older design assumptions behind many of them.
- 4:37:41QuestionDoes the Royal Navy paint battle honors or campaign ribbons on a ship's superstructure and turrets?AnswerQ&A
Normally no. Battle honours appear on boards, while exterior decoration more often consists of informal mottos, emblems, or other crew artwork.
- 4:41:44QuestionWhat would happen if the Scrap Iron Flotilla had modern destroyers of the time?AnswerQ&A
They would be used more often and would be more dangerous.
- 4:41:52QuestionWhat if the Scrap Iron Flotilla entered World War II with Daring-class destroyers in their 1954-55 configuration?AnswerQ&A
Their radar-directed 4.5-inch and 40 mm guns would be devastating to Axis aircraft in the Mediterranean.
- 4:42:53QuestionHow late did seaplane tenders remain in service?AnswerQ&A
Some are recalled as serving into the 1950s and 1960s, although the specific examples are uncertain.
- 4:43:26QuestionWould Theodor Krancke have handled Graf Spee's predicament differently from Hans Langsdorff?AnswerQ&A
Probably not by enough to matter; discovery, damage, and the enemy's ability to summon reinforcements leave any isolated surface raider with very few options.
- 4:44:39QuestionHow might Azur Lane's Hood be helped if memories of both historical HMS Hoods caused severe distress?AnswerQ&A
The fictional scenario is approached through conversation and the honourable service histories of both ships, with the imagined symptoms interpreted as trauma and dissociation.
- 4:51:51QuestionHow could a World War II seaplane tender still be serving as a US Coast Guard cutter in 1988?AnswerQ&A
The former tender remained a useful ship after its original aviation role declined, while seaplanes themselves retained ocean rescue value until other aircraft could replace them.
- 4:54:56QuestionWere seaplanes ever particularly useful in the Baltic?AnswerQ&A
Yes. There were few suitable airfields, while small inlets offered comparatively calm water for take-off and landing.
- 4:59:54Norton Sound's second career in weapons trialsNotable Point
The former seaplane tender provided a hull for VLS and Aegis trials associated with later American surface combatants.
