Study Bruships 132: Questions till the Milk or Pancreas Runs Out, a Dr. Alex Clarke video from 3 Dec 2023, with 75 time notes. Topics include Aircraft Carriers, Capital Ships, Live Q&A.
Time notes
- 12:43QuestionWhat is the difference between indicated horsepower and brake horsepower?AnswerQ&A
Indicated horsepower refers to theoretical engine output, while brake horsepower measures power delivered at the shaft.
- 20:30QuestionWere capital-ship interiors designed around peacetime duties?AnswerQ&A
Yes; peacetime functions formed part of the interior-design requirements for capital ships and flagships.
- 21:29QuestionHow would you refit a Roman-era trireme for modern naval combat?AnswerQ&A
Fit it out as a spy ship for intelligence collection.
- 23:35QuestionWhich aircraft carrier would have had the best peacetime career if the Second World War had not happened?AnswerQ&A
Probably Akagi, with the length of her career tied to Japan's ability to keep supporting its fleet.
- 24:22QuestionHow do stereoscopic and coincidence rangefinders compare?AnswerQ&A
Stereoscopic systems are more precise, while coincidence rangefinders acquire a rough range faster; using both would exploit each strength.
- 28:22QuestionWhat would a Nelson-class version derived from the L3 or K3 designs look like?AnswerQ&A
It would require a higher treaty limit or major cuts, probably losing a main turret and some secondary guns while carefully reducing armour.
- 30:51L3 and K3 shared armament but required very different powerNotable Point
The L3 battleship and K3 battlecruiser studies paired similar weapons with a large increase in machinery power for five extra knots.
- 39:45QuestionCould the 6-inch and 4.7-inch batteries be replaced with one universal armament?AnswerQ&A
Yes; a twin 5.5-inch battery could provide more dual-purpose barrels, though each would be less specialized.
- 41:23G3 and Lexington were designed for different fleet jobsNotable Point
Comparing the ships one-for-one misses the British independent-operation role and the American scouting role ahead of a battle fleet.
- 42:21QuestionWhat aircraft might Germany produce for Graf Zeppelin if it gained access to the Napier Sabre?AnswerQ&A
A Sabre-powered Barracuda-type strike aircraft and either a Seafire or Firebrand-type fighter are plausible choices.
- 43:00QuestionAre radical modular warship-construction methods likely in the near future?AnswerQ&A
The ideas are being explored, but no convincing delivered example comes to mind in this December 2023 assessment.
- 46:04QuestionWhat if Courageous-class ships were balanced 9.2-inch cruisers and other battlecruisers became carriers?AnswerQ&A
The treaty system would likely recognize a heavy-cruiser category, Britain might skip many 8-inch cruisers, and Admiral or Lion-class hulls would become carrier candidates.
- 47:21Cammell Laird carrier expertise suggests earlier design workNotable Point
References to Cammell Laird as a strike-carrier expert suggest design work before Ark Royal, with an Admiral-class hull as the proposed connection.
- 50:14QuestionHow would carrier conversions of Tiger and Lion compare with Courageous and Glorious?AnswerQ&A
Lion and Princess Royal would be the more likely pair. Their wider, deeper hulls and replacement boilers could make useful carriers, although unfinished Admiral-class hulls would be easier to convert.
- 54:52QuestionWould landing on a battlestar's left or right flight pod raise the same concerns as landing beside a carrier island?AnswerQ&A
Potentially, though a guiding system is imagined as a way to help with the landing.
- 55:26QuestionHow would Austria-Hungary respond if Dante Alighieri had been laid down earlier?AnswerQ&A
It would probably respond quickly, although the form of its new design is uncertain.
- 55:59QuestionDid Lion have better underwater protection than the Courageous class?AnswerQ&A
Yes; Lion had better existing underwater protection and more hull space available for additional protection.
- 56:13QuestionDid the Tiger class's two twin 6-inch mounts make sense as the final evolution of the treaty cruiser?AnswerQ&A
Not really; the ships should have carried more main guns.
- 57:51QuestionWhat would a US Navy fire-control table do for the ships in this scenario?AnswerQ&A
They would become much more accurate much sooner.
- 58:16QuestionWhat could replace Graf Zeppelin's 6-inch guns if they were removed during construction?AnswerQ&A
The weight and space could support more 88 mm weapons or other useful carrier equipment.
- 58:58QuestionWould a hypothetical HMS Lion carrier be more likely than Courageous to survive the encounter with U-29?AnswerQ&A
Probably slightly more likely, but the improvement would be small.
- 59:18QuestionHow much did outdated British aerospace construction contribute to Nimrod MRA4's problems?AnswerQ&A
Earlier government decisions are blamed for the inconsistent airframes, without a numerical estimate of their contribution to MRA4's problems.
- 1:01:27QuestionCould Wilhelm Canaris have worked with Catholic and British intelligence to extract anti-Nazis from Germany?AnswerQ&A
Covert cooperation is plausible given Canaris's concern for Germany's survival, but it remains speculation.
- 1:03:03QuestionCan concrete structures really be made to float?AnswerQ&A
Yes; the Mulberry harbours used enormous floating concrete components, far beyond the scale of a canoe.
- 1:03:35QuestionWho designed Royal Navy flagship interiors for peacetime imperial duties, and how were those spaces made impressive?AnswerQ&A
Naval constructors designed them, sometimes using forced perspective to make flagship spaces appear more imposing.
- 1:05:51QuestionHow closely do design sketches, detailed plans, and the completed ship match?AnswerQ&A
The build follows the detailed design much more closely than the initial sketch, but practical discoveries and changing requirements still force alterations.
- 1:06:42QuestionWhich book lists World War II destroyer escorts delayed by equipment shortages?AnswerQ&A
Norman Friedman's work on British destroyers is the suggested starting point.
- 1:07:02QuestionWhat is the strangest material successfully used to build a vessel?AnswerQ&A
Plastic is the first suggestion. Animal-hide coracles are another example, though their effectiveness is left uncertain.
- 1:08:25QuestionWhat happens if the Royal Navy chooses one of the fast H3 designs?AnswerQ&A
H3A offers six 18-inch guns and 33.5 knots, but G3 sacrifices only half a knot to gain three guns and a stronger rate of fire.
- 1:10:44QuestionWere test ships made from pykrete?AnswerQ&A
Some test construction is recalled, but it may have been a floating raft rather than a ship.
- 1:11:05QuestionWould a Lexington-class battlecruiser with 12-inch guns instead of 16-inch guns and better armour make more sense?AnswerQ&A
No. A 12-inch battery would put Lexington behind contemporary capital-ship armament and give the design a short useful life.
- 1:11:48QuestionWhat would retiring the Kirovs and Admiral Kuznetsov signal to other countries?AnswerQ&A
It would suggest that Russia had given up capabilities it could not replace, although retaining the ships also reveals that weakness.
- 1:12:31QuestionWithout naval treaties, what is the useful upper limit for a large cruiser?AnswerQ&A
Roughly 25,000 tons with 12-inch guns.
- 1:12:48QuestionWhy was the second Admiral Kuznetsov-class carrier slightly longer, wider, and heavier than her sister?AnswerQ&A
The tiny length difference is treated as measurement variation. The added beam is not explained confidently, although the second ship reflects attempts to improve the design.
- 1:16:44QuestionCould an H3 design have been adapted into an effective 35,000- to 40,000-ton treaty ship?AnswerQ&A
Physically yes, but the Royal Navy's dislike of a six-gun main battery made the layout unlikely to survive.
- 1:17:17Renown's turrets inform the debate over the proposed AgincourtNotable Point
The absence of triple 15-inch turrets from Renown and Repulse supports an 18-inch interpretation of the proposed Queen Elizabeth-class Agincourt.
- 1:18:53QuestionShould the United States have used Alaska-class resources to finish USS Kentucky?AnswerQ&A
Probably later in the war; Alaska would have been useful earlier, but Kentucky may have been the better late allocation.
- 1:20:00QuestionHow could the Admiral Kuznetsov class be made viable?AnswerQ&A
Redesign it from the beginning for a 50- to 60-year life, possibly with nuclear power, catapults, and much better maintenance access.
- 1:22:25QuestionWhat if Russia sold India all Kiev- and Kuznetsov-class carriers?AnswerQ&A
India would have six carriers and could probably keep three active. Pakistan would likely seek more Chinese submarines, while a Chinese construction response is not specified.
- 1:29:06QuestionHow might Italy respond to Alaska-class and German H-class ships?AnswerQ&A
Italy had the industrial base and design work to build a successor to the Littorio class, making an additional four battleships plausible if war were delayed.
- 1:31:06QuestionCould a G3 carrier conversion operate Mosquito-sized aircraft by the 1940s?AnswerQ&A
Physically yes, though Admiral-class conversions may be likelier and Air Ministry resistance to naval twin-engine aircraft would be a major obstacle.
- 1:32:11A separate 9.2-inch category leaves Britain choosing its smaller cruiser gunsNotable Point
In the proposed treaty system, Britain would probably pair its 9.2-inch heavy cruisers with 6-inch cruisers, with 7-inch weapons another possibility.
- 1:32:45QuestionHow would later wars change if the Great Lakes formed one enormous lake?AnswerQ&A
Campaigns would be more connected, while the larger sea-like waters would support battles increasingly independent of land fighting.
- 1:35:35QuestionWhy did the Soviet Union choose undersized reactors for the Kirov class?AnswerQ&A
Designers thought they would suffice and began from submarine-reactor concepts before recognizing that a surface ship needed a different plant.
- 1:38:17QuestionWould the Sea Vixen have benefited from wingtip tanks or different engines?AnswerQ&A
Wingtip tanks are rejected, and a different engine offers no clear gain once the required airframe changes are considered.
- 1:41:27QuestionHow practical is a catamaran aircraft-carrier design?AnswerQ&A
Its wide deck is attractive, but the beam amplifies height variation across the flight deck and complicates landings.
- 1:42:30QuestionWhy is less heard about Italian and Japanese armed merchant cruisers?AnswerQ&A
They achieved less than hoped: Italian ships were often sunk by British submarines, while Japanese ships sometimes met full cruisers.
- 1:42:58QuestionHow would other naval powers respond to HMS Vanguard?AnswerQ&A
A single Allied battleship would cause little alarm; the response could change if Vanguard had sisters.
- 1:44:53QuestionHow would Long Lance torpedoes change Royal Navy destroyer tactics?AnswerQ&A
Destroyers might fire a long-range salvo, reload with faster short-range settings, then launch again while closing with guns.
- 1:45:32QuestionWould a 41,000-ton battleship be better with twelve 15-inch guns or eight 16.5-inch guns?AnswerQ&A
Eight 16.5-inch guns are preferred for their probable range and heavier hits, although twelve 15-inch guns remain attractive.
- 1:46:21QuestionWould Britain develop better 16.5-inch guns for the Lion class if Nelson had used that calibre?AnswerQ&A
Yes; a 16.5-inch treaty limit would likely carry the G3 triple-turret design forward into the Lion class.
- 1:53:40Britain had the beginnings of a 16-inch Mark II battery for VanguardNotable Point
Four completed 16-inch Mark II guns suggest an alternative Vanguard armament, while Nelson-class spare-barrel numbers reveal the maintenance burden behind capital-ship gunnery.
- 1:55:28QuestionWould a trimaran aircraft carrier's flight deck create problems for pilots?AnswerQ&A
Yes; its extreme width can create large height differences across the deck in ocean waves, complicating landings.
- 1:56:05QuestionIn the age of modern electronics, do carrier islands still need to be so tall?AnswerQ&A
Height remains worthwhile because it provides reliable direct views over the bow and flight deck despite modern electronic aids.
- 1:57:19QuestionHow many rounds could a battleship gun barrel fire before replacement?AnswerQ&A
Roughly 750 to 800 is a broad guide, but charge, powder, and inspection condition make the real answer highly variable.
- 1:58:34QuestionWould Tiger-class helicopter cruisers work better on a larger, redesigned Minotaur-type hull?AnswerQ&A
A larger 1943 Minotaur-type hull would probably help considerably because the Tiger conversions needed more space.
- 1:59:35QuestionWas the Vulcan a good candidate for maritime patrol?AnswerQ&A
No; it consumed too much fuel and was designed for high-speed strike profiles rather than sustained low-altitude ocean patrol.
- 2:02:36QuestionIf Vanguard had remained in service for the Falklands War, would Vulcan attacks on Stanley airfield still have been necessary?AnswerQ&A
Vanguard's 15-inch guns could put Stanley airfield out of action from offshore, while also providing heavy fire support around San Carlos Bay.
- 2:08:07QuestionDid the Audacious-class carriers require the largest docks, or could other yards build them?AnswerQ&A
They needed large yards; some cruiser yards might build the hulls, but limited facilities narrowed the practical choices.
- 2:08:37QuestionHow difficult would it have been to rearm HMS Tiger with the 15-inch guns later used in Vanguard?AnswerQ&A
The 15-inch guns would require rebuilding the turret rings, magazines, and turret spaces; adapting Tiger for King George V-type 14-inch guns would be more viable.
- 2:10:20QuestionWhat tactics would keep a German U-boat captain alive until the end of the war in 1945?AnswerQ&A
Patrol cautiously in Arctic waters, hide near or under ice, avoid aircraft and convoys, and engage only when unusually safe.
- 2:11:19QuestionWould a surviving HMS Vanguard have deterred the Argentine invasion of the Falklands?AnswerQ&A
Not necessarily; Argentine planners might convince themselves Britain would not deploy the ship or that she was no longer combat-ready.
- 2:12:05QuestionHow many twin autoloading 6-inch guns could Britain place on a 1947 Minotaur-class cruiser?AnswerQ&A
Four or perhaps five twin 6-inch mounts, paired with roughly four or five twin 3-inch mounts on a full-size hull.
- 2:12:27QuestionWill Britain or the United States eventually restore large guns to warships?AnswerQ&A
Eight-inch guns might return; the suggested obstacle is presenting their reintroduction as a new development.
- 2:17:49QuestionWhat might a modern Royal Navy heavy cruiser look like if the type had been retained?AnswerQ&A
It could carry forward-mounted twin autoloading 8-inch or 9.2-inch guns backed by Mark 41 vertical-launch cells.
- 2:24:15QuestionWould a British 4.5-inch gun have been better than the American 3-inch/50 for first-generation JMSDF destroyers?AnswerQ&A
The 4.5-inch is more versatile, but the 3-inch/50 is the better anti-aircraft weapon and probably suits their self-defence role better.
- 2:24:42QuestionWhich navy has the better capital-ship naming system: Britain or the United States?AnswerQ&A
The naming traditions differ: US carriers discussed here commemorate presidents, other individuals and historic ships such as Enterprise.
- 2:26:04QuestionWhy did discipline aboard Pola break down into panic?AnswerQ&A
The crew knew they were surrounded and outgunned and that a disastrous encounter was imminent.
- 2:35:28QuestionWere treaty heavy cruisers defined by displacement or by their guns?AnswerQ&A
By their guns within a maximum displacement; the treaty set an upper limit, not a minimum.
- 2:35:47QuestionCould the Royal Navy boarding parties have understood why Pola's crew were drunk and disorderly if they had had time to assess the situation?AnswerQ&A
Probably, if they had the time and wanted to examine the circumstances.
- 2:38:46QuestionWhat is the best French battleship name?AnswerQ&A
Richelieu, because Cardinal Richelieu was a formidable namesake and the ship achieved lasting fame.
- 2:40:48QuestionHow would the proposed alternative hull lines change British 13.5-inch-gunned ships?AnswerQ&A
They might become somewhat faster, but the overall change would probably be modest.
- 2:44:26QuestionWhat would a British design armed with fourteen 12-inch guns require?AnswerQ&A
The large battery would require a somewhat longer hull, which might also make the ship slightly faster.
- 2:48:28QuestionDoes Dunkerque's layered battle history make it the best French battleship name?AnswerQ&A
It is a strong historical name, but the ship's unlucky career leaves Richelieu as the preferred choice.
- 2:51:21QuestionWhat would result from combining the Blackburn Blackburn with Béarn?AnswerQ&A
A Béarn designed to operate Blackburn Blackburn aircraft would need lifts suited to them.
