Time notes
- 1:16Why Bruships is built around questionsChapter
The livestream is framed as a seminar where questions and discussion complement faster lecture-style teaching.
- 10:49QuestionWhat is the relationship between HMS Tiger and the Japanese battlecruiser Kongo?AnswerQ&A
They were developed at a similar time around related ideas, but their internal designs differ enough that Tiger should not be treated as a copy of Kongo.
- 12:35QuestionWhat is the largest gun fitted to a destroyer, and when does a larger calibre make sense?AnswerQ&A
Some destroyers experimented with larger guns, but a weapon above five inches needs a clear purpose because it imposes major design costs on a destroyer-sized hull.
- 17:10QuestionHow did Tiger influence Hood, and what might Tiger have gained from Queen Elizabeth-style oil firing?AnswerQ&A
Oil firing could have made Tiger much faster, and a later rebuild might have made her useful, but Hood still embodied the battlecruiser concept rather than escaping its limits.
- 21:47Why six capital ships invite different compromises than twoNotable Point
The number of ships a navy can afford changes the balance between individual protection, speed, and fleet flexibility.
- 24:14QuestionHow would two surviving Canadian Tiger-type battlecruisers affect the Washington Naval Treaty?AnswerQ&A
Their capability could force negotiators to recognize Dominion capital ships in an additional treaty tier instead of fitting every navy into the historical ratios.
- 25:45QuestionWhat are common abuses of hindsight in naval history?AnswerQ&A
The central error is treating one eventual outcome as inevitable and assuming that contemporaries who anticipated another outcome were simply wrong.
- 29:32Why British and American warships solve different problemsNotable Point
Different geographic commitments make superficially different British and American design choices rational for each navy.
- 31:02QuestionWould the proposed Leopard have resembled a super Tiger or a smaller Hood?AnswerQ&A
It is sketched as a Tiger with 15-inch guns and small-tube boilers, probably capable of about 30 knots and more if the design used additional boiler power.
- 32:26QuestionWhy was the paired high- and low-pressure turbine arrangement used in ships such as Warspite more effective?AnswerQ&A
It improved energy efficiency by letting low-pressure turbines provide cruising power while high-pressure turbines supplied top speed.
- 33:01QuestionWhat popular naval myth about the Fairey Swordfish is most misleading?AnswerQ&A
Calling it World War I junk mistakes its biplane appearance for its design context; biplanes were still widely useful when the Swordfish was developed.
- 34:29QuestionCould the shell that destroyed Hood simply have travelled down a funnel?AnswerQ&A
It is extremely unlikely because the target area and shell trajectory demand exceptional alignment, unlike a deliberately aimed diving attack.
- 35:33QuestionWhere should Britain build two new large naval dry docks?AnswerQ&A
Portsmouth and the Cammell Laird area on the Mersey offer a useful combination of naval access, existing industry, and long-term resilience.
- 37:49The Allied war against Japan extended beyond the US NavyNotable Point
Australian forces, the Royal Navy, and other Allies disappear when the war against Japan is reduced to an American-only story.
- 38:21QuestionWhat contribution did the Isle of Man make to the Royal Navy during World War II?AnswerQ&A
The recollection is that many Manx people joined the war effort and that the island produced an unusually high concentration of Royal Navy captains, behind only Cornwall in the cited comparison.
- 40:27QuestionDid designers pursue capital ships with a single 16-inch-gun turret?AnswerQ&A
Not as a sensible modern arrangement, because a twin turret costs only modestly more and provides essential redundancy.
- 42:38QuestionWhy were HMS Tiger's two after turrets placed so far apart?AnswerQ&A
The spacing accommodated the boiler, turbine, and propeller-shaft arrangement inside the hull, and moving the turrets would require rebuilding much of the ship.
- 43:41QuestionWould five more Revenge-class battleships or more Renown-type battlecruisers have been more useful?AnswerQ&A
The Revenges were valuable in World War I, but additional Renowns would have offered the speed and mobility the Royal Navy needed more in World War II.
- 44:25QuestionWould a King George V with four quadruple 14-inch turrets be an effective answer to Yamato?AnswerQ&A
It would generate formidable volume of fire, but the comparison shown still makes twelve 16-inch guns the stronger main battery.
- 52:32QuestionHow did the Russian military buildup around Ukraine look on 20 February 2022?AnswerQ&A
Continued reinforcement favoured Russia numerically, but the visible buildup also made withdrawal politically costly and pushed any attack toward a much larger operation.
- 54:30Comparing gunnery through energy, range, and hit rateNotable Point
A proposed comparison method combines kinetic and explosive energy with range, rate of fire, and realistic hit assumptions.
- 57:50QuestionWhich Royal Navy designer deserves the strongest assessment: Tennyson d'Eyncourt or Goodall?AnswerQ&A
Goodall has the stronger claim by a narrow margin, especially for his carrier work and professional engagement with naval design debates.
- 58:58QuestionCan turret ammunition storage and a high nominal rate of fire be sustained in battle?AnswerQ&A
No. Initial ready ammunition can be expended quickly, after which the supply cycle and the depth of trained personnel govern the sustainable rate.
- 1:00:39QuestionWas Bismarck's reputation inflated after she sank Hood?AnswerQ&A
To an extent: Hood and Prince of Wales held a major paper advantage, but the battle's result made Bismarck appear more formidable than that matchup suggested.
- 1:03:55QuestionWhat is the purpose of turtleback armour?AnswerQ&A
It is intended to protect machinery and magazines from penetrating fire, preserving mobility and reducing the risk of catastrophic loss.
- 1:09:16QuestionWhat was wrong with Soviet Project 72 as an aircraft-carrier concept?AnswerQ&A
It inherited Graf Zeppelin's rigid design logic, including rail-based aircraft handling that locked in future operating and hangar constraints.
- 1:18:34QuestionWas the Admiral-class battlecruiser overdesigned?AnswerQ&A
Yes. Its design continued to answer a threat that had disappeared, while the likely Japanese and American opponents did not clearly require so costly a ship.
- 1:20:36QuestionWhy were the Revenge class's three-pounder Hotchkiss guns retained?AnswerQ&A
They remained handy for signalling, deterring small craft or aircraft, and supporting troops ashore.
- 1:22:06QuestionHow would 50 to 100 reliable Allied helicopters in service by 1943 affect the war?AnswerQ&A
They would transform island operations through precise vertical lift and give Allied anti-submarine forces a highly flexible new weapon.
- 1:26:04QuestionWhat might Courageous, Glorious, and Furious have looked like if they followed the path toward the Admiral class?AnswerQ&A
They could have resembled enlarged Renowns with three triple 15-inch turrets, creating a nine-gun evolutionary design.
- 1:26:56QuestionWere the Admiral-class battlecruisers designed mainly as an escalation against American ships?AnswerQ&A
No. They were conceived for global mobility and commerce warfare against the next plausible naval powers after Germany.
- 1:28:17QuestionHow can ammunition loading lead to a catastrophic harbour accident?AnswerQ&A
Insufficient practice and inexperienced crews rushing the loading process can turn an ordinary procedure into a disaster.
- 1:32:32QuestionWhy did the Washington Naval Treaty count battleships and battlecruisers together?AnswerQ&A
Because only Britain and Japan had battlecruisers, while the treaty's other principal negotiators had little reason to preserve a separate category.
- 1:33:02QuestionHow should the Swordfish be judged against contemporary aircraft designs?AnswerQ&A
Against its actual requirement it was a reliable, stable, easily maintained torpedo and reconnaissance platform optimized for daylight scouting and night attack.
- 1:38:44QuestionHow would four completed Admiral-class battlecruisers have been employed?AnswerQ&A
They could operate in hunting pairs or as fast leaders and heavy escorts for carrier task forces, with major consequences for carrier speed requirements.
- 1:44:45QuestionWas Hood likely to be retained with Vanguard after World War II?AnswerQ&A
Not necessarily; survival and wartime condition would determine retention, and older capital ships could emerge too worn for economical postwar service.
- 1:45:56QuestionHow did the cost of the Renown class compare with the Admiral class?AnswerQ&A
Hood cost about twice as much as Renown, so the Royal Navy could plausibly trade one highly ambitious ship for two proven fast capital ships.
- 1:47:45The Barracuda and its lost Rolls-Royce Exe advantageChapter
A Fleet Air Arm history traces the Barracuda's difficult development to an ambitious airframe and an engine programme that never reached production.
- 1:50:08QuestionHow can navies reconcile the destructive insanity of war with spending on warships?AnswerQ&A
The purpose is deterrence: credible, available forces should convince an opponent that war cannot deliver an acceptable victory, and that requires enough hulls and crews to survive routine disruption.
- 1:57:07QuestionWhy are Renown and Repulse often overshadowed by Hood?AnswerQ&A
Hood was larger and more glamorous, while the dramatic losses of Hood and Repulse created stronger popular narratives than Renown's career.
- 1:58:58QuestionHow might Denmark Strait change if Hood's first salvo hit Prinz Eugen?AnswerQ&A
Prinz Eugen would be in serious trouble, forcing Bismarck either to slow down or leave her exposed to the pursuing County-class cruisers.
- 2:01:28QuestionWhat if the Washington Naval Treaty required every power to scrap all capital ships and build anew?AnswerQ&A
Britain would be the likeliest power to fund a full replacement fleet, probably building about fifteen 28-knot Nelson-style ships while retiring older classes in stages.
- 2:01:57QuestionWhat carriers and aircraft might the Royal Navy use for a British version of the Doolittle Raid?AnswerQ&A
A large fleet carrier or pair of armoured carriers would launch Mosquitos, with Ark Royal a possibility only if she were available.
- 2:09:19Why a class of Renowns could outperform a mixed fast fleetNotable Point
Several ships of one proven class simplify logistics, training, and later modernization compared with four unique battlecruisers.
- 2:14:34QuestionWould advancing technology have made continued Renown construction obsolete?AnswerQ&A
No. The Royal Navy could evolve a proven Renown design, while repeated Admiral-class redesign risked spending money without completing ships.
- 2:16:54QuestionWould several Renowns have been too difficult to modernize in the 1930s?AnswerQ&A
No. Standardizing the fleet around fewer designs would make modernization easier because solutions could be copied across sister ships.
- 2:18:46QuestionHow did Royal Navy ships receive weather reports during World War II?AnswerQ&A
They used radio broadcasts and, on larger ships, their own instruments and forecasters, with carriers especially dependent on local forecasts.
- 2:19:25QuestionWhat would a 1970s Renown look like as a carrier-group leader?AnswerQ&A
It would carry a small gun battery, extensive air-defence missiles, close-in weapons, and a large helicopter deck with provision for Harriers.
- 2:22:43QuestionWhich Operation Crossroads target ship most deserved preservation?AnswerQ&A
Saratoga, because her naval record made her the strongest single preservation choice even among other significant targets such as Nagato.
- 2:25:07QuestionHow good was the French Joffre-class carrier under construction in 1940?AnswerQ&A
It was a major improvement over Bearn and a credible open-water carrier, although not an ideal Mediterranean design.
- 2:27:32QuestionWould CVA-01 have been less likely to be cancelled if it were nuclear powered?AnswerQ&A
Probably, because a nuclear carrier would become a prestigious national industrial project whose cancellation carried a much higher political cost.
- 2:28:43QuestionWhat was the point of building HMS Vanguard with old guns?AnswerQ&A
Reusing available turrets and guns let the Royal Navy pursue a fast battleship that could enter service sooner and make use of existing resources.
- 2:30:50QuestionWhat would an HMS Hood still serving in 1982 look like?AnswerQ&A
It would be a radically rebuilt missile-and-helicopter ship with new machinery and structure, and constructing a replacement would probably cost less.
- 2:37:55QuestionDo rough oceans significantly increase warship wear through hull flexing?AnswerQ&A
Yes. South Atlantic conditions are especially punishing and can drive hull wear to several times the normal Royal Navy rate.
- 2:38:31QuestionHow effective were Seafires against Zeros over Iwo Jima?AnswerQ&A
They were effective in the air, especially with radar direction, but their fragile landing gear made carrier recovery a serious hazard.
- 2:41:31QuestionWhat did gun crews do for comfort when operating in hot climates?AnswerQ&A
They opened ports and used fans when possible, but action required the gun position to be closed and secured.
- 2:47:00QuestionWhat is the naval equivalent of the Charge of the Light Brigade?AnswerQ&A
The Swordfish attack during the Channel Dash is a close operational parallel, though the specific chain-of-command misunderstanding at Balaclava is rarer aboard ships.
- 2:51:04Belgrade, church politics, and Patriarch Bogdanović's unsolved deathChapter
A book passage connects an unresolved 1913 clerical death with Serbian church politics and tension in the Balkans before World War I.
- 2:56:44Water security links dams, desalination, and renewable powerNotable Point
Water conflict and desalination lead to a wider lesson about using surplus renewable power for fresh water, hydrogen, and stored energy.
- 2:57:34QuestionCould a modernised Hood fight Yamato successfully?AnswerQ&A
Possibly under favourable radar-directed night conditions, but Hood would remain a battlecruiser facing 18-inch guns, so a Lion, Iowa, or paired Nelson and Rodney would be safer choices.
- 3:10:11QuestionWould swapping Allied and Axis naval commanders radically change the length of World War II?AnswerQ&A
Not by itself. Infrastructure, construction, and the forces already available impose limits that leadership cannot simply wish away.
- 3:13:06A fair method for comparing British and American shipsNotable Point
A warship should first be judged by how well it served its own navy's geographic and strategic requirements.
- 3:17:17Why Hood's proper target was trade, not YamatoNotable Point
Secondary armament and speed reveal a battlecruiser's mission: destroy cruisers and trade while battleships engage enemy capital ships.
- 3:21:13Why Graf Spee was trapped after the River PlateNotable Point
Once Graf Spee entered the River Plate, geography and the approaching Renown-Ark Royal force left almost no viable escape.
- 3:23:26How wartime logistics exposed India's infrastructure weaknessNotable Point
An imperial transport system optimized for coastal shipping lacked the inland redundancy needed when global war disrupted maritime movement.
- 3:24:53QuestionWhat would four completed Malta-class carriers mean for the postwar Royal Navy?AnswerQ&A
They could anchor a long-lived carrier fleet, possibly support a five-carrier policy, and undergo major angled-deck modernization.
- 3:26:16QuestionIf Japan did not enter World War II, would the Italian Navy face more Royal Navy forces?AnswerQ&A
Yes. Britain would retain more strength in the Mediterranean and would not need to build the same emergency Eastern Fleet from other theatres.
- 3:28:18QuestionIs the five-inch gun the sweet spot for a dual-purpose secondary against destroyers and cruisers?AnswerQ&A
It is well suited to anti-aircraft and anti-destroyer work, but a cruiser threat pushes the requirement toward six inches.
- 3:29:26QuestionCould Scharnhorst realistically defeat Rodney in a surface gun battle?AnswerQ&A
Not on favourable terms; Rodney's 16-inch guns and heavy armour make escape a better option for Scharnhorst than a close-range duel.
- 3:30:33QuestionWhy did Britain occupy Iceland during World War II, and how did Iceland react?AnswerQ&A
Britain feared Germany could seize undefended Iceland after taking Norway, while Icelanders objected and lodged formal protests.
- 3:35:04The capacity argument for HS2Notable Point
The case for HS2 centres on spare capacity that would let Britain close and modernise heavily used main lines without paralysing the network.
- 3:36:16Matthew Wright's route into HMS New Zealand's storyNotable Point
A shelf question becomes a recommendation for Matthew Wright's illustrated account of HMS New Zealand, her service, stories, and myths.
