Time notes
- 14:42Greenboy shells and the Battle of JutlandNotable Point
Greenboy shell trials suggest a much more damaging British performance at Jutland and expose the limits of calculated armour penetration.
- 24:20Why Hoche was called the Grand HotelNotable Point
Hoche's French Grand Hotel nickname and Carnot's building-like appearance explain the comparison between French pre-dreadnoughts and floating hotels.
- 26:10QuestionWas the French explosive called melanite related to melamine?AnswerQ&A
No. The similar names do not indicate a connection.
- 27:26QuestionJust after the war, would you buy an Austin Tilly or an Austin Champ from a surplus dealer, and why?AnswerQ&A
The Tilly appeals for its van layout and rear space; the Champ wins on power for climbing hills.
- 32:29QuestionWas the RAF trapped between Nimrod and having no maritime-patrol aircraft in the 2000s?AnswerQ&A
For a domestic or European replacement, largely yes. Completing MRA4 could have bridged the wait for P-8 and avoided a capability gap.
- 34:15Treasury control and short-term defence savingsNotable Point
A criticism of British defence budgeting links the Treasury's growing control to decisions that save money immediately while discarding nearly completed capabilities.
- 36:58QuestionWhat would happen if the Royal Navy captured Bismarck and brought her into an Allied port?AnswerQ&A
She would most likely be studied and stripped rather than quickly recommissioned; even an American rebuild or Free French carrier conversion would be costly and late.
- 44:08QuestionWas the British Daring class better than the American Forrest Sherman class?AnswerQ&A
Daring is given a slight edge as built because of its gun and torpedo armament, while either class could win an actual engagement.
- 46:26Daring's ancestry in a larger prewar L-class designNotable Point
Daring's layout is compared with Henderson's larger prewar L-class proposal, with added radar power, accommodation, and 40 mm armament.
- 49:04QuestionCould a five-centimeter undersea cable at thirty meters depth be cut accidentally, or would the damage probably be deliberate?AnswerQ&A
Either is possible. An anchor can cut it, but the cable's position relative to shipping lanes and anchorages determines how suspicious repeated incidents should appear.
- 50:44QuestionHow important were mothball fleets, and how did navies learn to preserve steam-and-steel warships?AnswerQ&A
They were valuable sources of surge capacity, but long-term preservation required interwar and Cold War development of active maintenance, moisture control, and reserve crews.
- 55:40Why restoring frigate reserves would require new shipsNotable Point
A proposed route back to spare frigate capacity links additional Type 32 construction to an eventual reserve role for Type 31.
- 56:34Why reserve planning cannot assume wars of choiceNotable Point
Reserve capacity declined under assumptions that nuclear war would end quickly and later conflicts could begin only when governments chose.
- 59:32Comparing empires without excusing colonialismNotable Point
Comparisons of colonial violence can condemn one empire especially strongly while retaining criticism of the others.
- 1:01:51QuestionWould a German equivalent of HMS Unicorn have changed the Second World War at sea?AnswerQ&A
A converted Seydlitz could help support aviation around Norway or operate as a light carrier, but industrial limits and British attacks would constrain its value.
- 1:04:35Converting a Königsberg into an aircraft-maintenance shipNotable Point
A proposed Königsberg rebuild divides the hull between stores, aircraft, and workshops, with substantial stability work and modest aircraft capacity.
- 1:08:31QuestionWhich navy has the strongest history of running its ships into the ground?AnswerQ&A
Canada is the choice, with worn transfers and abrupt funding reversals contributing to poor upkeep. Spain receives a separate distinction for losing a dreadnought through grounding during combat operations.
- 1:10:38QuestionWhat would have happened to the proposed Canadian Queen Elizabeth-class battleships?AnswerQ&A
Their operating cost could have turned them into an imperial gift. Three additional Queen Elizabeths might then have strengthened Britain's treaty-era case for the F3 battlecruiser instead of Nelson and Rodney.
- 1:12:38QuestionDid sailors return from the Navy with prize money to buy fishing vessels, and which fishing communities benefited?AnswerQ&A
There was movement between coastal trades and naval service, with prize money among its attractions. Cornish fishermen and smugglers receive the most attention, but no particular fishing fleet is identified as having expanded through vessels bought with those earnings.
- 1:16:47QuestionWhich 1920s propulsion systems would be preferable without the Washington Naval Treaty?AnswerQ&A
Oil-fired steam plants remain the main choice, using geared turbines for efficiency or turbo-electric transmission for control and machinery flexibility. Battleship preferences differ, while diesel engines offer a separate option for auxiliaries and reserve craft.
- 1:18:18Turbo-electric control for submarine hunting and carrier flight operationsNotable Point
Rapid machinery response could help escorts hunt submarines and carriers launch aircraft while spending less time away from fleet protection.
- 1:18:52QuestionWhy choose turbo-electric propulsion?AnswerQ&A
Flexible electrical distribution could let different generating units power any shaft, support maintenance and improve resilience under damage. The battleship comparison weighs those advantages against efficient sustained steaming.
- 1:23:09Diesels for reserve gunboats and monitorsNotable Point
Diesels could make intermittently used gunboats and monitors easier to activate while changing the maintenance burden during reserve service.
- 1:25:03QuestionDid locomotives adopt diesel-electric drive because a suitable mechanical clutch and gearbox were impractical?AnswerQ&A
Heavy trains put severe strain on mechanical transmissions, and stopping power to change gears is a problem when starting a large load. Electric transmission supplies strong starting torque and smooth power without those stepped gear changes.
- 1:31:17Sizing Warhammer Titans from their crew spacesNotable Point
A physical scale exercise uses crew positions, sensors, armor, and fictional interior descriptions to estimate much larger tabletop Titans.
- 1:35:48QuestionWere the Cimarron and Neosho-class oilers true workhorses of the United States Navy?AnswerQ&A
Yes. Their fuel-delivery role was essential, and major enlargements helped keep the older oilers useful through the Cold War.
- 1:37:14QuestionWhat was a jumboized Cimarron?AnswerQ&A
A Cimarron enlarged by cutting the ship apart and adding a new midsection, increasing capacity for the heavier fuel demands of Cold War fleets.
- 1:40:18QuestionWhich submarine development did Germany miss before the Second World War?AnswerQ&A
Germany missed the opportunity to make larger, longer-ranged boats its standard. A Type IX baseline and a larger ocean-going type could have strengthened the campaign, although they would not have won the war.
- 1:47:42The U-class hunter-killer path Britain did not takeNotable Point
A discarded development path could have turned Britain's U class into R-class-style hunter-killers stationed outside French U-boat bases.
- 1:49:24QuestionWith Stena Immaculate out of commission, would a replacement be built or would operators wait for repairs?AnswerQ&A
Another tanker could be hired. Whether the owner orders a new ship depends on its finances and how urgently it needs replacement capacity.
- 1:50:01QuestionWhich planned but unbuilt ship designs should have been completed?AnswerQ&A
Normandie, Lyon and a French battlecruiser project are the preferred completions, although Normandie's cancellation is understandable and Lyon offers more room for later upgrades.
- 1:51:51Modernizing Lyon with Dunkerque gunsNotable Point
Lyon's sixteen-gun layout offered room for major reconstruction, but choosing Dunkerque guns over a 15-inch conversion could determine whether the ship was ready when war began.
- 1:54:52QuestionWhich planned but unbuilt capital-ship designs would have been worth completing?AnswerQ&A
F3 or a close derivative and a King George V with the new 15-inch/45 gun are leading choices. A Spanish 13.5-inch battleship and the unbuilt Agincourt depend on additional funding or unresolved design questions.
- 1:55:42QuestionWas there a way for France to avoid capital-ship designs such as Hoche?AnswerQ&A
Possibly by delaying the programme and developing a fresh design instead of continuing the existing sequence.
- 1:57:37QuestionWhich unbuilt carrier designs would have been worth completing?AnswerQ&A
Joffre and Malta are preferred completions. An Admiral-class carrier with a vast hangar and deck-edge lifts is a more speculative choice whose original design cannot be produced as proof.
- 1:58:19The unbuilt armored-flight-deck EssexNotable Point
Redistributing Essex-class armour to the flight deck is proposed as a way to reduce attack damage, preserve carrier availability and retain the air group.
- 2:03:35QuestionWhich other unbuilt battleships would be interesting to complete?AnswerQ&A
An all-forward North Carolina design, the entire Lion class, and a Soviet battleship class large enough to create a politically threatening squadron.
- 2:04:38QuestionWas the Royal Navy determined from the outset to use STOVL aircraft on the Queen Elizabeth-class carriers?AnswerQ&A
STOVL was the politically achievable choice because it aligned Royal Navy carrier plans with RAF aircraft needs and reduced the risk of losing the program in an inter-service funding battle.
- 2:07:34Hawkeye and Wedgetail in British carrier fundingNotable Point
A catapult carrier could affect the RAF's aircraft purchases if funding pressure forced a choice between carrier-based Hawkeye and land-based Wedgetail.
- 2:14:16QuestionWhich modern Western navy without major high-end assets would be most useful as an allied escort force?AnswerQ&A
The Netherlands, Norway and Denmark are leading choices, with Greece another candidate. Actual readiness qualifies the recommendations, especially after the Red Sea failures discussed here.
- 2:18:27QuestionIs Germany's naval air arm doing better than its surface fleet?AnswerQ&A
Its Tornado anti-shipping aircraft have been folded into the Luftwaffe. The Marineflieger may still exist formally, but independent naval strike capacity is the concern.
- 2:19:19QuestionIs there hope for the Constellation class when organizations involved with the LCS program are building it?AnswerQ&A
Yes, but the outcome may be extreme: either another severe procurement failure or a corrected, conventional frigate that restores useful fleet numbers.
- 2:22:49LCS firefighting limits and the 45-knot requirementNotable Point
The Bonhomme Richard fire raises questions about LCS support to other ships, followed by criticism of requiring a large warship to chase small boats at 45 knots.
- 2:25:05QuestionWhat are the merits and problems of the submitted 1960s super-capital-ship concept?AnswerQ&A
It resembles an enormous prestige project, with concerns about its cost and a superstructure positioned behind the ballistic-missile launchers.
- 2:31:47QuestionDid Japan build an equivalent to American PT boats, British motor launches, or German Schnellboote?AnswerQ&A
Japan had coastal craft with torpedoes and several kinds of gun armament. Whether these formed a directly comparable dedicated fast-attack force is uncertain, with infrastructure identified as a constraint.
- 2:48:05El Alto's accidental high-altitude aircraft boneyardNotable Point
Aircraft abandoned around El Alto formed an informal collection of postwar aviation history, although a later check suggests that many had been moved elsewhere around the airport.
- 2:50:29QuestionWhat if the battleships damaged at Pearl Harbor were beyond repair, and would that hasten the carrier's replacement of the battleship?AnswerQ&A
Early wartime operations would change little, but later bombardment capacity would shrink and additional new battleship or carrier construction might receive more urgency.
- 2:54:51QuestionShould the Royal Navy mothball Type 45 destroyers after Type 83 enters service?AnswerQ&A
That depends on their condition and the Type 83 programme. Options include conventional reserve service or conversion into heavily automated missile magazines with small crews.
- 2:59:49QuestionWhat happens if Bismarck reaches a French Atlantic port after Sheffield is not attacked?AnswerQ&A
Britain would face a larger capital-ship concentration in France, requiring stronger surveillance and a sustained effort to destroy it before separate or combined breakouts.
- 3:03:23A hypothetical carrier, bomber, and submarine attack on Bismarck in FranceNotable Point
A proposed surprise attack combines carrier torpedo aircraft with RAF illumination, then uses mines and submarines to obstruct escape from harbour.
- 3:09:47Why Royal Navy multi-carrier plans exceeded wartime opportunitiesNotable Point
Interwar work had addressed coordinated carrier operations, but dispersed wartime commitments often prevented the Royal Navy from assembling the planned force.
- 3:11:24QuestionWhat air group would suit an Incomparable-class hull converted into a carrier like HMS Eagle?AnswerQ&A
An estimated eighty to one hundred operational aircraft plus many spares, with unused capacity encouraging larger twin-engine reconnaissance and strike aircraft.
- 3:14:06QuestionWhat would the Zero look like if British carriers operated large twin-engine aircraft?AnswerQ&A
It could remain broadly similar if Japan retained its single-seat fighter requirements; the larger British change could be a multi-role twin-engine airframe shared across missions.
- 3:16:28QuestionWould a Swordfish still emerge if the Royal Navy developed twin-engine carrier aircraft?AnswerQ&A
A single-engine torpedo bomber would still be needed for smaller carriers, although its design could differ and the Swordfish name alone might survive.
- 3:17:19QuestionWhy was PQ 17's heavy escort ordered not to pass 25 degrees east?AnswerQ&A
Because carrier effectiveness declined while German land-based air danger increased, and a late German surface interception became progressively less likely unless intelligence showed a sortie underway.
- 3:19:59QuestionWould an LHD customized to maintain drone boats at sea make sense as a command ship?AnswerQ&A
Yes. A converted amphibious ship could coordinate the boats and provide facilities for maintenance and rearming at sea.
- 3:22:07QuestionHow could the Royal Navy find two or three thousand people to crew an Incomparable-sized carrier in the 1920s?AnswerQ&A
It could redirect personnel released by treaty-era ship retirements, and the carrier would need fewer heavy-gun crews than the battlecruiser from which it was converted.
- 3:25:00QuestionWhat would happen if the last County-class destroyers were replaced by the missile-armed helicopter cruisers contemplated at the time?AnswerQ&A
Keeping the Batch 2 Counties is one preference, although helicopter cruisers offer more aviation capacity. The comparison depends on which escort-cruiser design is chosen and how much deck space and armament it sacrifices.
- 3:31:41The escort-cruiser studies deferred by PolarisNotable Point
A 13,250-ton helicopter-and-missile cruiser was revised and deferred as Polaris spending took priority, while its aviation role remained in longer-term planning.
- 3:34:36QuestionHow would fifteen to twenty improved X1 cruiser submarines change Britain's Second World War?AnswerQ&A
Improved successors could add long-range raider hunting, convoy attack, resupply and commando support. Their value would depend on reliable machinery and deployment, with disagreement over the risks and opportunities in the Mediterranean.
- 3:42:52QuestionWhat is the oldest ship still in service and actively used by a navy?AnswerQ&A
A Brazilian river monitor is the suggested answer, but its name is not settled. A Russian floating dock is also mentioned, with doubts about its condition.
- 3:44:42QuestionWho needed to be replaced to get the Mark 14 torpedo working early in the Second World War?AnswerQ&A
Most of the Bureau of Ordnance is blamed, with King and Mush Morton invoked as imagined sources of pressure. No specific replacement list is given.
- 3:47:12QuestionWhat would the ultimate gun-based anti-aircraft destroyer look like?AnswerQ&A
The modern proposal combines larger guns for reach, numerous rapid-firing 3-inch mounts with strong broadside coverage, and as many effective close-in systems as the ship can accommodate.
- 3:52:41QuestionWhat kind of fleet did Richard I take on Crusade?AnswerQ&A
Many cogs, with poor performance in storms.
- 3:53:30QuestionShould Britain maintain naval shipyards while builders bid competitively for the work?AnswerQ&A
Yes, provided there is enough work to make the arrangement economically viable.
- 3:53:53QuestionWhat carriers would interwar navies build if 2,000-horsepower aircraft engines or basic jets existed in 1935?AnswerQ&A
Carrier designs would remain broadly familiar, with Britain probably seeking an Implacable-like design earlier. More powerful aircraft would not remove the need for protection while long-range warning remained uncertain.
- 4:01:38Thread forms and surface finishes in electrical fittingsNotable Point
Thread shape, internal seams and sharp edges matter when substitute pipe fittings carry electrical conductors.
- 4:07:17QuestionDid the crew know how to use a tap and die set correctly?AnswerQ&A
Run-on's view is that they either do not know or do not care. A dispute over conduit size illustrates his wider concern about following instructions he considers technically wrong.
- 4:10:21Photographic records and uncertainty about completed wiringNotable Point
Timestamped photographs preserve the condition of completed wiring and help examine disputed reports of later faults.
