Time notes
- 1:35QuestionWhy did France not invest more in naval infrastructure between the wars?AnswerQ&A
Constraints existed, but unstable politics and indecision over spending were the decisive practical obstacles.
- 6:23QuestionWere warships designed to go backwards as well as forwards?AnswerQ&A
Generally no; carriers inspired theories about operating aircraft in both directions, but the arrangement proved impractical.
- 7:15QuestionWhy would treaty powers make concessions to keep Britain inside the naval treaty system?AnswerQ&A
Britain's industrial and naval position meant that its absence could unravel limits for everyone else.
- 9:16QuestionIf a Hood-type ship with four triple 15-inch turrets were built, would the treaty powers ignore it?AnswerQ&A
No; its firepower, speed, and likely 45,000-ton displacement would force the treaty system to adjust.
- 11:04QuestionHow useful was the Fairey Firefly to the Royal Navy?AnswerQ&A
It was a capable multirole aircraft that delivered the range of functions the Royal Navy needed from one type.
- 11:56QuestionDid painting fake bow waves and similar visual countermeasures help defeat naval ranging?AnswerQ&A
They could mislead the first salvo, but their value faded once the enemy tracked the ship and corrected its fire.
- 13:04QuestionHow plausible was it for Brazil to operate two Riachuelo-class battleships after the Second World War?AnswerQ&A
It was technically plausible if Brazil maintained its infrastructure and supplied the money and political support.
- 13:29QuestionDid Britain build weak export warships on the assumption that it might later have to fight them?AnswerQ&A
No; Britain generally relied on superiority in numbers and the better training that a larger fleet could sustain.
- 14:25QuestionIf the treaty system had survived, how could the United States build Enterprise without openly violating its allowance?AnswerQ&A
It would probably apply an escalator clause to the carrier category.
- 15:04QuestionWhat does a modified Alaska with four triple 12-inch turrets offer?AnswerQ&A
It would be capable in the large-cruiser role, but that role still has to justify building it instead of an Iowa.
- 16:14QuestionWere service conditions aboard a fourth rate closer to a third rate or a fifth rate?AnswerQ&A
They could be worse in general because the ship had fifth-rate space but a crew closer to a third rate's size.
- 16:37QuestionHow plausible is a substantially lengthened and widened Lion-class battleship?AnswerQ&A
Those changes amount to a new hull, so their plausibility depends on a mission that justifies the redesign.
- 17:18QuestionHow do 18-inch and 16-inch guns compare in rate of fire and practical firepower?AnswerQ&A
The smaller guns can fire more often and in greater numbers, which may create a much larger volume of fire.
- 19:34The engineering problem behind 20-inch gunsNotable Point
A 20-inch naval gun is constrained less by a single crane or pit than by barrel metallurgy, weight, handling, and turret machinery.
- 24:08Why radar did not eliminate ranging salvosNotable Point
Tight shell grouping is not enough if the range solution is wrong, and early radar still depended on human fire-control work.
- 27:11QuestionHave historians overestimated how successful the Washington naval negotiations were for the United States?AnswerQ&A
Yes; early American confidence weakened at London in 1930 and after closer inspection of Britain's treaty battleships.
- 28:41QuestionWhat would Senator Tillman propose if Britain built Incomparable?AnswerQ&A
He would press for the largest Tillman battleship the United States could build.
- 29:14QuestionCould an 18-inch gun fire a saboted 16.5-inch projectile to gain velocity without lengthening the barrel?AnswerQ&A
Yes in principle, but only if metallurgy and sabot technology were developed far enough to make it reliable.
- 31:20QuestionDid naval treaties distinguish destroyers, cruisers, and battleships by displacement, gun size, or both?AnswerQ&A
Both, but displacement was the primary classification and gun calibre was secondary.
- 31:59QuestionHow long did it take to build a U-class submarine?AnswerQ&A
About eighteen months for the cited peacetime example, with wartime examples taking around a year or less.
- 34:54QuestionWhat changes would a Tiger-class cruiser need to become a properly structured and armored heavy cruiser?AnswerQ&A
Its armament and belt were plausible, but the finished ship would probably need to displace about 13,000 to 14,000 tons standard.
- 38:02QuestionHow common was it for blockading ships to use captured provisions, and were those stores often poisoned?AnswerQ&A
Using captured provisions was fairly common, but deliberate poisoning was very rare.
- 39:08QuestionWhat materials were sails made from between 1500 and 1850?AnswerQ&A
Linen and cotton were common, with hemp and earlier wool also used; cotton became more practical for large sails.
- 42:44QuestionWhat books would you recommend for studying modern maritime strategy?AnswerQ&A
Start with B. J. Armstrong's 21st-century series and consider Alessio Patalano's Maritime Strategy and Naval Innovation for a deeper, more expensive option.
- 48:03QuestionCould British industry build dry-dock gantry cranes on the scale used at major continental yards?AnswerQ&A
Yes; it would be difficult and expensive, but the necessary heavy-engineering capabilities already existed.
- 49:02Why 16.5 inches could be a useful gun compromiseNotable Point
A 16.5-inch gun could retain a 16-inch weapon's rate of fire while delivering a meaningfully heavier shell.
- 50:51QuestionIs there a practical size limit for fuel-oil supercarriers?AnswerQ&A
Yes; the limiting factors include docks, construction and launch capacity, and the ability to fuel and operate the carrier.
- 51:18QuestionWhat if Katō had lived and civilian politicians had retained control of Japan longer?AnswerQ&A
Japan might have remained more politically balanced and less dominated by militarist leadership.
- 52:32QuestionWhy was HMS Argus not upgraded from six single 4-inch guns to six twins?AnswerQ&A
Space, firing arcs, and the amount of reconstruction made the upgrade poor value for Argus.
- 56:22QuestionWhat advantage would diagonal bracing have offered if introduced before the Seven Years' War?AnswerQ&A
It would strengthen hulls, support heavier armament, and make more efficient use of available timber.
- 57:17QuestionWhat if Greece received one or two Tegetthoff-class dreadnoughts, and how might they be modernized?AnswerQ&A
They could become useful eastern Mediterranean fleet units after machinery and anti-aircraft upgrades, probably operating with the Royal Navy.
- 58:50QuestionWhy did the Iowa class not carry centerline 5-inch secondary mounts?AnswerQ&A
The added height, weight, exposure, and layout costs were not worth the extra battery.
- 59:39QuestionWhat difference would a modernisation make to the R class in the Second World War?AnswerQ&A
They would be more survivable and flexible, potentially contributing more to Far East deterrence and escort work.
- 1:00:51QuestionWho would build the better first-generation quadruple 14-inch turret, Britain or the United States?AnswerQ&A
Neither would be trouble-free; both would have different problems, and the American design might lead toward a quad 16-inch turret.
- 1:02:48QuestionWhy was Bismarck designed with three propeller shafts rather than four?AnswerQ&A
Probably to save weight and hull space, although four shafts would have been better for survivability.
- 1:03:32QuestionWhat should Finland have built alongside its coastal-defence ships?AnswerQ&A
More coastal-defence pairs backed by reinforced destroyer flotillas and fortifications.
- 1:04:25QuestionShould a Dallinger-style rule requiring half of U.S. warships to be built in navy yards be revived?AnswerQ&A
Only after accounting for the large cost of rebuilding, locating, staffing, and operating public shipyards.
- 1:05:31QuestionIf the United States needed a new ship for the battleship role in the 1980s, what would it build?AnswerQ&A
An Iowa-sized, fast Aegis strike-cruiser type with missile launchers and substantial guns.
- 1:06:08QuestionIs there a naval equivalent of trench warfare?AnswerQ&A
Blockade and commerce raiding are the closest equivalents because they wage prolonged economic attrition at sea.
- 1:06:53QuestionHow long did it take to start the marine diesels of ships such as the Deutschland class?AnswerQ&A
The engines may start quickly, but preparing the associated systems can take a couple of hours or more.
- 1:08:25QuestionWhat kind of navy could Canada have afforded during the interwar years?AnswerQ&A
About four cruisers, eighteen destroyers, and eighteen sloops, divided into balanced Atlantic and Pacific forces.
- 1:09:20QuestionAt what level of technology could naval guns larger than 16 inches become practical?AnswerQ&A
Most plausibly in the 1950s, or perhaps the 1940s after uninterrupted development without treaty constraints.
- 1:11:31QuestionWere linguistic or translation issues responsible for Germany calling so many warships frigates?AnswerQ&A
Mainly no; the label was political, though German naval rank terminology reinforced it.
- 1:12:03QuestionDid anyone try to place as many torpedo tubes as possible on one surface ship?AnswerQ&A
Beatty proposed a carrier-based torpedo farm, but the range disadvantage against guns made it a poor idea.
- 1:12:28QuestionWhat was the first triple-turret battleship built in British yards?AnswerQ&A
Nelson and Rodney, although British firms had built triple turrets earlier for testing and foreign ships.
- 1:15:23QuestionHow would Greece use three Radetzky-class semi-dreadnoughts?AnswerQ&A
After modernisation, they would probably serve as convoy escorts, while Tegetthoff-class dreadnoughts could join fleet actions.
- 1:18:07QuestionIf Britain had American industrial capacity in the Second World War, which capital ships would be completed?AnswerQ&A
The Lion-class battleships and the planned carriers would be completed, including the later fleet carriers.
- 1:18:50QuestionDoes a Courageous-class refit with fewer 4.7-inch guns, twenty-four 40 mm pom-poms, and more machine guns make sense?AnswerQ&A
The extra machine guns add little beside twenty-four pom-poms; 20 mm Oerlikons are more useful, and removing four 4.7-inch guns is hard to justify.
- 1:19:28QuestionHow much modification would Courageous need to carry about fifty-two aircraft, and would widening the beam help?AnswerQ&A
Full-length widening would amount to rebuilding the ship; deck-edge lifts are a more practical way to improve aircraft capacity.
- 1:21:03QuestionHow large would an Archer-style battleship with seven triple 16-inch turrets be?AnswerQ&A
Roughly 55,000 to 60,000 tons for a ship carrying twenty-one 16-inch guns.
- 1:22:33QuestionHow would two Béarn-class carriers affect France, and could Béarn be rebuilt into a fast fleet carrier?AnswerQ&A
Two would provide emergency escort-carrier capacity, but a fast 30,000-ton rebuild would really be a new ship.
- 1:23:09QuestionWhy did the Royal Navy build armored carriers after Ark Royal instead of simply repeating her?AnswerQ&A
Ark Royal was optimized for a large strike group, while Illustrious was armored for close fleet operations and distant theaters with limited repair support.
- 1:24:09QuestionWhat would the careers and modernization of two Dutch Lion-class battlecruisers look like?AnswerQ&A
They would likely gain 14-inch guns, stronger machinery, modern anti-aircraft control, and serve as Far Eastern flagships with Force Z or ABDA.
- 1:26:44QuestionIf sailing ships remained in use longer, would navies have adopted four-deckers?AnswerQ&A
Probably not as a normal type, because the fourth deck created excessive topweight and stability problems.
- 1:28:44QuestionWhich navy got capital-ship development most right during the twentieth century?AnswerQ&A
Overall the United States, because it both built the ships and developed the supporting fleet, although the answer varies by period.
- 1:30:42QuestionHow would reliable British high-pressure steam plants by 1934 affect ship designs and refits?AnswerQ&A
They would enter the fleet before the 1936 design lock-in, improving most new ships and major refits with faster, more efficient machinery.
- 1:33:52QuestionDid an admiral or commodore displace a ship's captain, or were special flag cabins provided?AnswerQ&A
On a fifth rate the captain could be displaced, while fourth and third rates had enough deck space for separate flag accommodation.
- 1:35:05QuestionWhat was the worst non-ship naval system of the interwar period?AnswerQ&A
Quadruple machine-gun mounts are a stronger candidate than the UP launcher because they wasted space and produced no useful development path.
- 1:41:45QuestionIf a Japanese carrier-conversion hull were wrecked in the Kantō earthquake, could Japan build a replacement?AnswerQ&A
Yes, but the replacement would be a normal carrier rather than another experimental ship like Hōshō.
- 1:42:09QuestionHow would French Lions and Italian Francesco Caracciolos affect British treaty construction and modernization?AnswerQ&A
Britain would likely seek four faster treaty battleships and prioritize speed upgrades across more of the Queen Elizabeth class.
- 1:46:42QuestionWas the U.S. Navy right to turn away from 18-inch guns after testing them?AnswerQ&A
Yes for an American battle fleet, while Japan could reach a different answer because it wanted deterrent value from exceptional guns.
- 1:57:50QuestionWhat if Britain ignored the Washington treaty and secretly built two over-limit G3s?AnswerQ&A
The other powers would protest strongly, but treaty revision is more likely than war or forced scrapping.
- 1:58:41QuestionIf the dominions could each receive one British treaty capital ship, who would get them?AnswerQ&A
Australia would claim the first and probably seek both; New Zealand could receive the second, which would likely operate mainly from Australia.
- 2:00:45QuestionHow would a steady seven-ship interwar programme affect British shipbuilding by the late 1930s?AnswerQ&A
It would preserve the industrial base and make the later wartime expansion much easier.
- 2:02:30QuestionCould the Second Pacific Squadron have reached East Asia faster through the Northeast Passage with icebreakers?AnswerQ&A
No; Russia lacked sufficient large icebreakers and logistics, and the squadron risked breaking down or becoming trapped.
- 2:03:30QuestionCould an Alaska-class large cruiser still be in active service today?AnswerQ&A
Only after such extensive rebuilding that it would effectively be a new ship with the old name.
- 2:04:00QuestionHow effective were the British imperial navies compared with one another?AnswerQ&A
The Royal Navy ranked first and Australia second; the others were held back by limited numbers, funding, or government support.
- 2:07:54QuestionWould converting an Admiral-class battlecruiser have produced a better carrier than converting Courageous or Glorious?AnswerQ&A
Yes; converting an unfinished Admiral would allow a cleaner Lexington-style redesign without rebuilding a worn completed hull.
- 2:13:27QuestionBy 1940 were battlecruisers obsolete, or did they still offer a useful specialized role?AnswerQ&A
They retained niche advantages, but fast battleships covered enough of both roles to be the better financial and operational choice.
- 2:18:43QuestionCould a treaty battleship be built for a 16-inch belt, carry thinner armour in peacetime, and receive stored plates in wartime?AnswerQ&A
It could be designed that way, but swapping thick one-piece belt plates would require advance manufacture and a major refit.
- 2:19:48QuestionHow much armor does a heavy cruiser need against 8-inch gunfire?AnswerQ&A
It depends on range, but roughly eight inches is the suggested protection level.
- 2:21:11QuestionWhat if practical helicopter anti-submarine warfare arrived while Second World War escorts were being designed?AnswerQ&A
Escorts would need to be larger, with room for hangars and multiple helicopters, but could still be built in useful numbers.
- 2:23:17QuestionWould treaty navies have benefited from separate battleship and battlecruiser limits?AnswerQ&A
Britain saw advantages, but the United States feared that separate ratios would produce new allocation disputes and fleet imbalances.
- 2:23:56QuestionWould a Second World War escort carrier be more effective if converted into a helicopter carrier?AnswerQ&A
Use a mixed air group: fixed-wing aircraft for long-range patrol and a few helicopters for close ASW prosecution.
- 2:26:44QuestionHow important were Baltic German officers to the Imperial Russian Navy?AnswerQ&A
They were highly important because they supplied Baltic operating experience, especially against Sweden, while other groups helped build the wider fleet.
- 2:29:55QuestionWhat Italian capital ships could fit within an eight-ship treaty allowance?AnswerQ&A
Four Francesco Caracciolos plus selected rebuilt dreadnoughts could fit, but Italy probably could not retain all of its older ships as well.
- 2:37:04QuestionWould Japan have been better off building minelaying submarines instead of aircraft-carrying submarines?AnswerQ&A
Probably, because they could mine American harbors and Pearl Harbor's approaches to create sustained disruption.
- 2:44:07QuestionIf missiles had never appeared, what would replace 40 mm Bofors anti-aircraft guns?AnswerQ&A
Probably nothing directly: 40 mm guns would remain, while 76 mm weapons might become more common.
- 2:48:25QuestionWhat might a naval war between the United States and Soviet Union during the Korean War look like?AnswerQ&A
It would begin as a heavily one-sided Western carrier offensive, with Soviet weakness at long-range submarine warfare and a serious risk of nuclear escalation.
- 2:49:51QuestionHow does Jutland change if both sides are compelled to keep closing the range?AnswerQ&A
It becomes a bitter, high-loss fleet battle in which British numerical superiority probably wins.
- 2:52:35QuestionHow plausible is decommissioning an old carrier and using it as a guided-weapons target?AnswerQ&A
It depends on the war situation, available replacements, and whether the navy has enough crews for the ships it keeps.
- 2:54:16QuestionHow important was Simonstown to the Royal Navy?AnswerQ&A
It was a valuable peacetime station and a critical wartime logistics and operating base for the Indian Ocean.
- 2:55:45QuestionWould giving the N3 the G3's extra length and an F3 turret layout raise it to 28 knots?AnswerQ&A
Not by length alone; with more machinery it could probably reach about 27 knots and perhaps approach 28 after further work.
- 2:57:00QuestionWhen does a large destroyer become a small light cruiser?AnswerQ&A
When it is large enough and its guns, rather than torpedoes, become the primary fighting system.
- 2:58:46QuestionHow realistic is a Halland-style destroyer armed with twin 152 mm guns?AnswerQ&A
It is plausible because Scandinavian yards, especially Sweden's, could build large and powerfully armed destroyers.
- 3:05:51QuestionWould Renown be better with 5.5-inch guns, and how many could she carry?AnswerQ&A
Yes; about six twin 5.5-inch mounts would provide a practical replacement battery.
- 3:08:18QuestionHow many sloops could Britain afford and crew before the Second World War?AnswerQ&A
Eight to twelve a year, potentially about 120 by 1939, with most reserve-manned until mobilization.
- 3:13:48QuestionWhat if all eight R-class ships were 30-knot battleships with nine 15-inch guns?AnswerQ&A
They would dominate Royal Navy planning, multiply fast-battleship coverage, and force rival designs to become substantially stronger.
- 3:18:49QuestionHow would surviving gun-armed Courageous-class ships affect German raider deployments?AnswerQ&A
Their speed and four 15-inch guns would make them dangerous opponents for Deutschland-class raiders.
- 3:22:53QuestionWould a reliable autoloading 5.25-inch gun make Britain arm future destroyers with it?AnswerQ&A
Not the treaty-era destroyers, but the larger Battle class could plausibly carry it.
- 3:26:15QuestionWhat impact would the invention of transistors in 1938 have on the Second World War?AnswerQ&A
Radar, codebreaking, and early computers would become easier to build and substantially more capable.
- 3:27:13QuestionWas Britain's choice of smaller carriers a long-term mistake under treaty limits?AnswerQ&A
Not necessarily: global commitments made the ability to field carriers in many places more valuable than maximizing each hull's size.
- 3:31:36QuestionWhat extra equipment and facilities did a destroyer leader carry?AnswerQ&A
It carried extra accommodation, radios, medical support, and command spaces for the flotilla staff.
- 3:34:48QuestionWhy did the Royal Navy not pursue carriers below 10,000 tons for treaty advantages?AnswerQ&A
Because a useful fleet carrier needed roughly 11,000 to 12,000 tons; smaller designs did not work well enough.
- 3:37:01QuestionShould a carrier's landing-area elevators be flush with the flight deck or several feet below it?AnswerQ&A
Usually slightly below the deck, but not four to six feet down; aircraft approach speed shapes the final compromise.
- 3:38:19QuestionIf Britain knew in early 1938 that war would begin in eighteen months, what naval work should it accelerate?AnswerQ&A
Prioritise carriers and their support, escorts, submarines, destroyers, and rapid refits over slower prestige projects.
- 3:43:18QuestionWhat made armour disappear from modern warships?AnswerQ&A
Missile threats are difficult to armour against comprehensively, making compartmentalisation a more useful survivability investment.
- 3:44:11QuestionIf George III visited the American colonies, would he travel in a royal yacht or a warship?AnswerQ&A
Probably a suitably fast third rate with a large escort, because contemporary royal yachts were not designed for transatlantic voyages.
- 3:45:55QuestionWhich Second World War ships or systems most deserve the question, why did we build these?AnswerQ&A
The Deutschland class and secretive Yamato programme stand out, while some U.S. shortcomings were doctrinal rather than failures of ship design.
- 3:49:06QuestionWhat is the advantage of a distributed armour scheme over all-or-nothing armour?AnswerQ&A
It can protect a wider area, whereas all-or-nothing armour gives a smaller citadel much greater protection.
- 3:51:10QuestionHow seaworthy were the U.S. Navy's original six frigates compared with their contemporaries?AnswerQ&A
They were sound ocean-going ships, although their power attracted stronger enemies and President's weaker bracing reduced her seakeeping.
