Bruships 178: Naval History or Exercise
Study Bruships 178: Naval History or Exercise, a Dr. Alex Clarke video from 12 Jan 2025, with 96 time notes. Topics include Naval Aviation, Naval Logistics, Naval Procurement.
Time notes
- 5:12QuestionWhich was better as a dual-purpose weapon, the British QF 6-inch Mark V or the American 6-inch/47?AnswerQ&A
Neither was decisively superior: the American gun had a slight anti-aircraft edge, while the British weapon favored surface action and barrel-life requirements tied to Royal Navy logistics and doctrine.
- 11:38Lion's heavier 16-inch shell and intended battle rangeNotable Point
Similar shell weights concealed different British and American priorities for trajectory and damage at the expected engagement range.
- 14:20QuestionWhy did British aircraft carriers sometimes have prominent round-downs on their flight decks?AnswerQ&A
They improved airflow over the deck, helping aircraft generate lift during takeoff.
- 14:59QuestionHow would NATO and non-NATO powers react if Spain carried out its ten-year naval expansion and modernization plan?AnswerQ&A
NATO would broadly welcome the added balanced force, but the decisive question would be whether successive governments sustained the ships, crews, and supporting fleet for the full decade.
- 17:29QuestionWhat was HMS Urge?AnswerQ&A
She was a successful Royal Navy U-class submarine that damaged Vittorio Veneto and was later lost to a mine in April 1942.
- 19:14QuestionCan a shipbuilding industry remain competitive while being kept afloat by state support?AnswerQ&A
Yes, if support takes the form of steady work or state dockyards paired with competitive design; open-ended subsidy alone is unlikely to preserve efficiency.
- 24:49Keeping Royal Dockyards at a distance from political interferenceNotable Point
A proposal to restore state dockyards depends on giving naval leadership enough authority to manage engineering work and political demands.
- 27:29QuestionHow would a fifty-metre rise or fall in sea level during the twentieth century change naval and global strategy?AnswerQ&A
It would remake coastlines, ports, river systems, invasion routes, and industrial regions so thoroughly that almost every major power would need a different maritime strategy.
- 35:34QuestionWas the Royal Navy's eighteenth-century timber crisis a political fiction used to win more funding?AnswerQ&A
It was politically useful, but the underlying danger came from poor administration and incomplete knowledge of timber stocks rather than a wholly invented shortage.
- 41:00QuestionWhat were the largest Allied and Axis logistical failures of World War II?AnswerQ&A
The proposed examples are Axis dependence on inadequate fuel and industry and Allied failure to use supplies at Singapore, although Singapore's classification as a logistical failure is disputed.
- 43:50QuestionHow would Savo Island have changed if Mikawa attacked the transports as well as the Allied warships?AnswerQ&A
He could have sunk transports, but the assessment assumes many were already largely unloaded; diverting fire towards them would expose his force to surviving Allied warships.
- 47:09QuestionCould the Royal Navy have developed the Royal Marines into a larger, formally separate service in the seventeenth century?AnswerQ&A
Yes, but chiefly if government distrust of the Army created demand for an alternative armed force; otherwise Army opposition would constrain expansion.
- 48:42QuestionWould the UK naval concepts raised in the question become real projects or remain proposals?AnswerQ&A
Their prospects are uncertain. An interesting concept does not establish that ships or facilities will be built.
- 51:07QuestionHow many Type 45 destroyers would be needed to defend Baltic airspace?AnswerQ&A
Two might cover a simple rotation, but a serious commitment would require more ships so the force could absorb heavy air attack and rotate with full missile magazines.
- 54:27QuestionDid the postwar Royal Navy have a plan and forces to counter threats around Suez?AnswerQ&A
Yes. It maintained forces east of Suez and could converge from both directions, using carriers and other assets to deter or execute an intervention.
- 56:58QuestionCould Hiryū have escaped or withdrawn from the Battle of Midway?AnswerQ&A
Yes, if her commander withdrew rather than launching the strike on Yorktown; the counterattack and escape were incompatible choices.
- 1:00:40QuestionHow would World War II change if Germany made modular warship construction work by 1939?AnswerQ&A
Germany would gain capacity, but the Allies would probably share the technique and exploit it at greater scale, while German overengineering could erode much of the benefit.
- 1:04:17Graf Zeppelin and the danger of poor system integrationNotable Point
Graf Zeppelin's gun and catapult arrangements illustrate how individually attractive design choices could interfere in operation.
- 1:06:51QuestionWhy did Britain allow Germany to scrap HMS Hibernia after working to restrict German shipbuilding under the Treaty of Versailles?AnswerQ&A
Because the obsolete, disarmed pre-dreadnought contained little that could materially help German naval reconstruction.
- 1:09:42QuestionIn the VLS era, where does the distinction between frigates, destroyers, and cruisers lie?AnswerQ&A
The operating navy defines it; broadly, ASW escorts tend to be frigates and air-warfare escorts destroyers, while many perform cruiser-like duties regardless of label.
- 1:16:59QuestionWhat vessels did the Angles, Saxons, and Jutes use to reach England?AnswerQ&A
They used northern European vessels broadly similar to Viking longships, shaped by local shipbuilding developments and contact with Roman maritime technology.
- 1:22:15QuestionCould Harland and Wolff build Royal Navy LHDs after completing the Fleet Solid Support ships?AnswerQ&A
It is too far ahead to judge confidently: the RFA work could take roughly another decade, and the political situation could change substantially.
- 1:22:54Why a policy needs someone who can explain itNotable Point
A January 2025 political argument separates skill at persuading voters from agreement with a politician's policies.
- 1:27:39QuestionWhich admirals are the Royal Navy's favorites when naming ships?AnswerQ&A
Duncan and Blake recur strongly, while Hawke deserves more use but suffers from weaker modern recognition.
- 1:28:36QuestionWhat if a lucky hit sank one Royal Navy battlecruiser at the Battle of the Falkland Islands?AnswerQ&A
Britain would probably still win, but the loss would trigger an intensive investigation into how an Invincible-class ship succumbed to the force it was built to defeat.
- 1:31:39QuestionHow possible was it for Zuikaku to participate in the Battle of Midway?AnswerQ&A
It would require a major doctrinal change that allowed the Japanese Navy to regenerate her depleted air group in time.
- 1:34:46QuestionWhat would have changed in Japanese doctrine for Shimakaze to carry three sextuple 21-inch torpedo mountings instead of Type 93 torpedoes?AnswerQ&A
Japan would have to conclude that the Long Lance's oxygen hazards, maintenance burden, and risk to ships and crews outweighed its range and speed.
- 1:37:34QuestionWould NATO answer Soviet chemical weapons in kind or escalate to nuclear weapons?AnswerQ&A
The stated logic pointed toward nuclear escalation because most NATO powers did not officially maintain chemical weapons for retaliation in kind.
- 1:37:58QuestionWhy is China building a fleet of icebreakers?AnswerQ&A
They support access to raw materials and Arctic opportunities, and can also increase capacity available in cooperation with Russia.
- 1:39:24QuestionCan icebreakers be converted into warships?AnswerQ&A
They can carry weapons, but available space and the need to keep systems working in extreme cold limit the conversion.
- 1:40:40QuestionWhat was the best destroyer of World War II?AnswerQ&A
It depends on national requirements: the Tribals suited Britain's war and Gearings suited the United States, while German designs were notably ill-matched to their operational needs.
- 1:43:23QuestionIs there a warship so ugly that even a naval enthusiast cannot love it?AnswerQ&A
Long Beach attracts the strongest aesthetic objection, while her defenders cite the radar installation and challenge the affection shown for Hoche.
- 1:46:49QuestionHow would control or procurement of Greenland affect allied strategy near the GIUK gap?AnswerQ&A
Expanded basing rights were judged more likely than American acquisition, with Danish Arctic patrol capacity remaining an important allied contribution.
- 1:50:15QuestionIs renting out territory for a foreign military base such a big deal?AnswerQ&A
The base can draw its host into another power's conflict, although Greenland already belongs to NATO through Denmark and already has strategic exposure.
- 1:52:08Diego Garcia, the Panama Canal, and maritime bargaining leverageNotable Point
Maximalist territorial language may seek bargaining leverage over basing rights, infrastructure control, and Chinese participation rather than literal annexation.
- 1:54:06QuestionWhat is your view of the new-school Jeune École and its modern interpretations?AnswerQ&A
It repeats the old temptation to buy security cheaply through one technology; drones are valuable, but for decades they are more likely to complement crewed systems than replace them wholesale.
- 1:57:42Why future obsolescence does not justify retiring useful ships nowNotable Point
A replacement expected in twenty years leaves an existing system with years of useful service before the transition.
- 2:00:52QuestionWhat did Britain consider its largest amphibious assault, and did D-Day count?AnswerQ&A
D-Day is debatable in this framing; among completed British operations, Torch and Husky are the principal contenders, with larger assaults planned but not carried out.
- 2:01:45QuestionWhich Royal Navy flag officers from the Second World War have been treated most unfairly by history?AnswerQ&A
Somerville and Harwood are strong candidates because later criticism often neglects Somerville's health and exhaustion and Harwood's lack of preparation for interservice political conflict.
- 2:03:50QuestionWould a purpose-built 33,000-ton Royal Navy carrier based on the G3 have resembled HMS Hermes?AnswerQ&A
An Eagle-style arrangement is the tentative proposal, extrapolated from a brief description of an Admiral-class conversion.
- 2:11:19QuestionWhich other ship of the line should have been preserved beside HMS Victory?AnswerQ&A
Preferences include HMS Africa, a French-built seventy-four captured at Trafalgar, and Santísima Trinidad, although her size prompts objections to placing her beside Victory.
- 2:15:44QuestionWho was the craziest destroyer captain in each navy?AnswerQ&A
Several captains qualify through attacks on cruisers or battleships, so the comparison offers extreme examples without choosing a winner for every navy.
- 2:17:40QuestionCould Scharnhorst have survived North Cape, and what effect would her survival have?AnswerQ&A
If she escaped, she would keep tying down Allied forces and remain vulnerable to bombing; survival until 1945 raises speculative possibilities including a Soviet transfer or atomic testing.
- 2:19:38British teams collecting German military equipment in 1945Notable Point
The race for German equipment included separate Royal Navy, RAF, and Army parties, with Ian Fleming associated with the naval effort.
- 2:24:48QuestionHow would the Imperium change if the Adeptus Mechanicus embraced invention?AnswerQ&A
It would be much stronger, but the fictional setting gives it institutional barriers to innovation: lost knowledge, fear of experimentation, restricted education and unequal permission to try new ideas.
- 2:30:48QuestionWhich World War II fast battleship gave its nation the greatest capability for most of the war?AnswerQ&A
There is no single answer: King George V has a strong British case, North Carolina an American one, and Scharnhorst arguably added the most relative capability to its own navy.
- 2:34:53QuestionCould the Panama Canal be expanded to super-Panamax capacity for Ford-class carriers?AnswerQ&A
Yes in engineering terms, but only at very high cost, making political funding rather than technical feasibility the real obstacle.
- 2:35:20QuestionCould Britain, Canada, and Australia develop a common LHD?AnswerQ&A
Potentially, but their replacement schedules and priorities are misaligned, while crews, escorts, and Canada's submarine problem make a near-term common project unlikely.
- 2:36:30QuestionIf surviving Littorio-class battleships were returned intact to Italy, how long could they last in Cold War service?AnswerQ&A
Perhaps another thirty years with refits, but wartime damage and Allied restrictions would determine which hulls were available and worth sustaining.
- 2:37:09Water reuse in Panama Canal locksNotable Point
Water-saving lock operation offers a way to address canal constraints by reducing the water needed for each transit.
- 2:39:31QuestionWas the proposed 1990s VLS modernization of the Iowa class worthwhile?AnswerQ&A
It would add capability, but the stated cost comparison favoured another Ticonderoga. At that scale of expenditure, building a new battleship was another possibility.
- 2:40:41QuestionWhy consider building a new battleship in the late Cold War?AnswerQ&A
Heavy naval guns offered a way to support forces in northern Norway while leaving carriers available for operations against Soviet naval bastions.
- 2:43:05Sixteen-inch design studies and the case for eight-inch alternativesNotable Point
A disagreement over gun calibre distinguishes remembered 16-inch design studies from a proposed alternative using automatic 8-inch guns.
- 2:50:05Iowa turret monitors and the future of heavy-gun presence shipsNotable Point
Reusing Iowa turrets raises different industrial questions from building a new heavy-gun fleet, with post-Cold War presence as a possible later role.
- 2:54:51QuestionWhich places belong on a five-day naval-history tour of southern England?AnswerQ&A
Build the trip around Portsmouth, then use London for HMS Belfast, Greenwich and Cutty Sark, Hendon, and a prearranged visit to HMS Wellington.
- 2:58:53QuestionIf Washington allowed twenty British, twenty American and fourteen Japanese capital ships under a 10:10:7 ratio, which additional ships might each navy build?AnswerQ&A
The United States and Japan would probably complete more 16-inch ships. Britain could build more Nelson-style or faster capital ships, while any enlarged carrier allowance would introduce a further major change.
- 3:02:03Why guns and missiles solve different naval fire-support problemsNotable Point
Shell volume, missile range, shore-battery elevation, visible deterrence, and task-group protection give guns and missiles different roles.
- 3:07:31QuestionWhat were the advantages and disadvantages of Gangut-style minimal superstructures, and why did the layout fade after the 1920s?AnswerQ&A
The low profile reduced exposed structure and suited Baltic service, but sacrificed the height, working space, and command facilities needed for longer-range and more global operations.
- 3:10:34QuestionDid the British Empire use a system similar to modern U.S. combatant commanders?AnswerQ&A
It had regional and functional senior commanders, but command was more often tailored to a station or operation than organized into today's permanent joint combatant commands.
- 3:12:22QuestionWhat percentage of GDP should a country spend on defence in peace and war?AnswerQ&A
There is no universal percentage: countries should fund the forces their threats and commitments require, using GDP targets only as rough political shorthand.
- 3:15:27QuestionWhat teething problems could Canada face when moving from AOPS construction to Type 26 frigates, and how could they be reduced?AnswerQ&A
There will be problems, but allied Type 26 experience and the industrial continuity provided by AOPS should reduce the risk of repeating the same mistakes.
- 3:18:36QuestionWere British paper warships more realistic than German and Soviet designs?AnswerQ&A
They often look more realistic because Britain possessed the industry to build them, forcing design studies to become conservative and reduce risk as procurement approached.
- 3:24:43QuestionHow would Town-class cruisers differ if built with sixteen 6-inch guns?AnswerQ&A
Their roles would change little, but quadruple turrets would trade individual-gun rate for more barrels and might accelerate British work on automated gun handling.
- 3:27:27QuestionIf the resources used to conquer Crete were diverted to Malta, would the assault go badly wrong?AnswerQ&A
Yes. Malta's difficult landing terrain and established defensive arrangements made the prospect much worse than simply transferring the force used at Crete.
- 3:34:40Veterans, family ties and determination in local defenceNotable Point
The argument for taking the Home Guard seriously combines wartime experience with the motivation to protect families and familiar ground.
- 3:40:28QuestionHow important was USS Ranger to the outcome of Operation Torch?AnswerQ&A
She was useful rather than decisive, chiefly because her availability avoided diverting a more capable carrier from other wartime demands.
- 3:43:43QuestionWhy did interwar countries merge their air arms into a single force despite the concept's later shortcomings?AnswerQ&A
They expected lower costs and believed air specialists should control an indivisible new form of warfare, but this often neglected naval aviation's distinct operational and maintenance needs.
- 3:46:12QuestionWhy did HMS Lioness never become as durable a Royal Navy name as HMS Lion?AnswerQ&A
The names were too easy to confuse in radio traffic, and Lion's stronger battle honors gave it priority.
- 3:46:52QuestionGiven its training and maintenance problems, is there a better system than forward presence?AnswerQ&A
Forward presence remains useful, but training and maintenance require sufficient ships and crews for sustainable rotations.
- 3:47:58QuestionHow did Danish ships of the line compare with those of other major fleets?AnswerQ&A
They were usually smaller and shallower-draft because Denmark needed ships that could operate flexibly in both the Baltic and North Sea.
- 3:48:19QuestionWhich supposedly obsolete weapon systems have made a comeback?AnswerQ&A
Guns are the clearest example: they returned to ships and aircraft because sustained, economical volume of fire remains essential alongside precision missiles.
- 3:49:54QuestionHow should Spain rebuild its navy from 1923 to reach half the strength of Italy?AnswerQ&A
Repair the industrial base and existing fleet first, then use carefully chosen foreign purchases and partnerships to build submarines, aviation, cruisers, and eventually capital ships without overwhelming logistics.
- 3:54:50QuestionWhich would be harder for the Axis to crack, Malta or Gibraltar?AnswerQ&A
Both are formidable: Gibraltar combines rock defenses with easier British reinforcement, while Malta forces an exposed assault fleet to linger beside a heavily defended island.
- 3:56:08QuestionHow effective was dazzle camouflage?AnswerQ&A
It could make long-range tracking and quick firing estimates more difficult, which was the limited task it was designed to perform.
- 3:56:35QuestionWould an Admiral-class carrier conversion have an air group comparable to an Essex?AnswerQ&A
It might carry about ninety aircraft, but Royal Navy interest in larger twin-engine strike and shadowing aircraft would probably keep its count somewhat lower.
- 3:57:31L’Orient and the limits of the Océan-class first ratesNotable Point
L’Orient was one member of a large 118-gun class rather than a unique template, and British treatment of captured Commerce de Marseille is cited as evidence of practical shortcomings.
- 4:01:18QuestionWhere was the most frightening place for a civilian or merchant sailor to serve at sea during World War II?AnswerQ&A
The Arctic, because a sailor in the water had almost no chance of surviving long enough for rescue.
- 4:02:27QuestionWhat ratio of land-based strike aircraft is needed to deter a carrier group?AnswerQ&A
No stable ratio exists; the defender must locate the moving group, reach it, and overwhelm its defenses, while the attacker can add carriers and use submarines or missiles against fixed bases.
- 4:05:14Why capital ships normally sailed with escortsNotable Point
Battleships and carriers depended on accompanying cruisers and destroyers; fast ships such as Renown were better placed to make the occasional solo passage.
- 4:06:35QuestionShould the River-class replacement have a helicopter hangar?AnswerQ&A
Not a full conventional hangar; it should support UAVs and might use a deployable shelter for temporary helicopter maintenance.
- 4:08:53QuestionCould the Royal Navy have negotiated three smaller carriers instead of two Queen Elizabeth-class ships?AnswerQ&A
No. The authorized package was specifically two British-built, non-nuclear carriers, and changing that bargain risked losing the program rather than gaining a third hull.
- 4:10:42QuestionWhat stopped Santísima Trinidad from becoming the model for later first-rate ships of the line?AnswerQ&A
Her repeated, incomplete modifications produced an incoherent and unpopular design rather than a stable pattern worth copying.
- 4:11:08QuestionWere nuclear-powered escorts too few to support high-speed carrier movements?AnswerQ&A
The rare sprint scenario required about one nuclear escort per carrier, with another racing out from the destination group to meet the incoming force.
- 4:12:48QuestionDo developments in the Black Sea mean close blockade tactics have returned?AnswerQ&A
Not in the strict sense: naval movement is constrained, but commerce continues and both sides are conducting limited economic warfare rather than a complete close blockade.
- 4:13:58QuestionWhat force did the Royal Navy use to guard whaling fleets in the world wars?AnswerQ&A
Mostly sloops and frigates, supplemented by corvettes, trawlers, and other small escorts.
- 4:14:38QuestionWhat are three especially interesting maritime mysteries?AnswerQ&A
The choices are an Australian warship lost to a German commerce raider, missing U-class submarines and the electrical failure tentatively identified with South Dakota.
- 4:24:27QuestionWere there notable medieval naval commanders besides William de Leybourne?AnswerQ&A
Yes, but many are difficult to name because surviving accounts credit the king rather than the officer actually commanding at sea.
- 4:26:26QuestionWill Hedgehog-like anti-submarine weapons return to Western warships?AnswerQ&A
Possibly in modernized form, including Swedish systems and gun-launched ASW rounds intended for submarines or underwater drones.
- 4:27:42QuestionWhy did the United States oppose Canadian nuclear submarines during the Cold War?AnswerQ&A
The proposed explanation is fear of greater Canadian independence. A guest also suggests national ego, while explicitly disclaiming knowledge of the specific decision.
- 4:28:13QuestionWhat if Shinano survived the war and reached Tokyo Bay for the surrender?AnswerQ&A
She would probably have been expended in American postwar weapons testing rather than preserved, likely becoming a radioactive artificial reef.
- 4:28:58QuestionAre there plans to supplement or replace the River-class Batch 2 patrol vessels?AnswerQ&A
No specific plan was identified, but OPVs are a familiar British way to bridge shipyard workload gaps when no larger order is ready.
- 4:31:05QuestionWhy did few late Cold War states pursue power projection on the American scale?AnswerQ&A
Many projected power regionally, but global reach required spending and force structure beyond what their interests or budgets justified.
- 4:32:21QuestionHow do MIRVs affect navies, and how can a carrier strike group be protected from them?AnswerQ&A
Aegis defenses help, but no shield is total; moving dispersed ships complicate targeting, and the launch itself risks catastrophic nuclear misinterpretation and escalation.
- 4:40:46QuestionWhich historic Royal Navy ship name should return on a vessel of the same general class?AnswerQ&A
Princess Royal is the preferred revival, ideally within a royal-themed class of major surface combatants.
- 4:47:01QuestionCould electromagnetic-pulse weapons disable a warship?AnswerQ&A
They can disable unhardened systems, but shielding, hardened electronics and resettable protection can limit the damage on a warship.
- 4:48:33Why navigators still need charts and dead reckoningNotable Point
Manual navigation keeps a ship moving when satellites or electronic consoles fail, but crews must practise those skills before an emergency.
