Bruships 175: Pre- Christmas Party 2024
Study Bruships 175: Pre- Christmas Party 2024, a Dr. Alex Clarke video from 22 Dec 2024, with 87 time notes. Topics include Live Q&A, Naval History, Naval Logistics.
Time notes
- 7:23A Christmas shelf of destroyers, U-boats, shipyards, cruisers, and naval aircraftChapter
Six recent books cover personal wartime memoirs, convoy history, shipbuilding, cruiser design, and Royal Navy aviation.
- 13:48QuestionWas Tirpitz an effective warship?AnswerQ&A
Tirpitz tied down substantial British forces as a fleet-in-being, but Hitler's restrictions prevented a combat test and made her an inefficient way to deliver that effect.
- 15:17Why Scharnhorst's label mattered less than her operational fitNotable Point
The panel moves beyond the battleship-versus-battlecruiser label to ask whether Scharnhorst's design suited the war Germany actually fought.
- 20:32QuestionHow would the Second World War change if the RAF focused on Coastal Command rather than Bomber Command?AnswerQ&A
Britain could field more long-range maritime patrol aircraft without eliminating its heavy-bomber force, improving early U-boat attrition, reconnaissance, navigation, and warning during campaigns such as Norway.
- 26:58QuestionIf Tirpitz escaped to fight, how effective would her gunnery be?AnswerQ&A
Her radar-directed equipment was at least comparable to Bismarck's, but long intervals between full-range exercises would leave the crew less practiced in using it.
- 27:55QuestionHow often were bouncing bombs used, and how did they differ from ordinary skip bombing?AnswerQ&A
Upkeep was used against the dams, while the anti-ship Highball weapon was developed but did not reach its intended operational use; ordinary bombs could also be skipped across water without being purpose-built bouncing weapons.
- 32:05QuestionWhat changes if Scharnhorst replaces Admiral Graf Spee in September 1939 while the initial British force remains the same?AnswerQ&A
Scharnhorst could keep the cruisers at range and escape more readily, but Britain would bring a heavier carrier-and-capital-ship hunting force against her.
- 35:46The War of Jenkins' Ear, slave trading, and Spanish American silverNotable Point
A date slip opens a concise explanation of how slave trading and access to Spanish American silver sat behind the War of Jenkins' Ear.
- 38:22QuestionDid navies razee first- or second-rate ships to create unusually powerful third-rates?AnswerQ&A
Occasionally ships were cut down, but the result lacked the dramatic structural and sailing advantages gained by converting a ship of the line into a frigate, so a purpose-built third-rate was usually better.
- 42:36Why Vasa warns against uniform heavy gun decksNotable Point
Vasa illustrates why upper gun decks normally carried lighter weapons than lower decks.
- 43:47QuestionHow often did R-class battleships ram enemy vessels, and what was their most unusual attempt?AnswerQ&A
The panel cannot identify a successful R-class ram, but notes that battleships routinely tried to ram submarines caught near the surface and that HMS Dreadnought famously sank one that way.
- 45:46The emergency plan to turn R-class battleships into coastal fortressesNotable Point
In an invasion emergency, an old battleship could be deliberately grounded to place heavy guns and Royal Marines directly inside a threatened landing area.
- 48:09QuestionWhen were convoys first used, and by whom?AnswerQ&A
Convoy-like protection is ancient rather than the invention of one modern navy: Chinese, Greek, and Roman forces all grouped merchant ships under warship escort.
- 50:14Why improvised carrier substitutes fail in contested airspaceNotable Point
Britain's carrier gap could be bridged in permissive operations, but a contested theater restores the need for organic air power and early warning at sea.
- 53:24Why secure codes do not defeat signals traffic analysisNotable Point
An enemy can learn where forces are and how they are organized from radio activity even without reading the encrypted messages.
- 54:21Why merchant crews, not hulls, become the wartime bottleneckNotable Point
Governments can requisition merchant ships or compel convoy cooperation, but trained crews and compatible operating practices are harder to create quickly.
- 58:05QuestionWhy did Italian warships carry red-and-white bow markings, and did other navies use similar schemes?AnswerQ&A
They were aerial recognition markings intended to reduce friendly fire; other navies painted flags, names, or symbols on decks and turrets for the same purpose.
- 1:06:54QuestionIf the Second World War began later and Britain completed several Lions and Vanguards, would more capital ships survive into the postwar fleet?AnswerQ&A
Yes, especially the Lions, while a larger modern force would gradually displace the unmodernized R class and preserve only selected older ships after reconstruction.
- 1:16:06QuestionHow would Britain and the United States respond if the Soviet Union built a much larger Sverdlov-class force and completed the Stalingrad-class battlecruisers in the late 1950s?AnswerQ&A
A global Soviet raiding fleet would force a different Western naval policy and could preserve a British program for new aircraft carriers in the late 1950s.
- 1:19:02QuestionWhat could overturn the modern pattern of submarines, aircraft carriers, and escorts?AnswerQ&A
Only technology that removes their underlying roles: portable air power, ambush raiding, protection, and hunting. New platforms are more likely to inherit those roles than abolish them.
- 1:26:06QuestionWhat if Germany adopted genuine industrial standardization before or early in the Second World War?AnswerQ&A
Production would become much more efficient, but the essential reform was freezing designs long enough to build interchangeable equipment instead of introducing small changes throughout a nominal production run.
- 1:31:00QuestionWas the F3 design intended to use three shafts with a separate cruising shaft?AnswerQ&A
No. The Royal Navy expected two shafts to carry the required power, with cruising and high-speed turbine arrangements serving each shaft rather than a dedicated center shaft.
- 1:39:09QuestionShould Japan have announced the Yamato class or spent its resources elsewhere?AnswerQ&A
A deterrent has to be visible to influence an opponent, so revealing the ships once launched could have disrupted Allied planning even though it would also trigger faster British and American construction.
- 1:45:31QuestionHow close did German submarines bring Britain to starvation in the First World War?AnswerQ&A
Contemporary estimates gave Britain about ninety days of food, while the practical margin may have been roughly one hundred to 110 days.
- 1:46:51QuestionWould a late-1930s modernization of Hood change her battle with Bismarck?AnswerQ&A
Radar fire control and renewed machinery would improve Hood's performance, but the fatal shell trajectory could still occur and the exact result depends on the modernization package.
- 1:51:05Why modern allies can share carrier coverageNotable Point
Modern British, French, and American carrier forces can pool availability in ways treaty-era fleets could not.
- 1:53:47QuestionHow important was Liberty-ship production to the Allied war effort?AnswerQ&A
It was indispensable, because mass-produced cargo capacity sustained global operations; a larger, faster interwar merchant fleet would also have made German interception substantially harder.
- 1:56:17QuestionWas unifying defense and abolishing separate ministers for the armed services a good reform?AnswerQ&A
Unification improved coordination, but Britain lost dedicated political advocates responsible for explaining each service's needs in Cabinet and Parliament.
- 1:59:23QuestionWhat impact did British and American infrastructure have on victory in the world wars?AnswerQ&A
It made sustained victory possible by allowing the Allies to mass adequate equipment, expand production, and fund research until an enemy's initial technical advantage was overtaken or overwhelmed.
- 2:01:45QuestionWhat impact did the sinking of Lusitania have on the First World War?AnswerQ&A
It sharply affected public and political opinion, but its practical influence depended on how leaders and the press used an event that reinforced trends already moving against Germany.
- 2:04:13QuestionWhat happens if the United States delays the Two-Ocean Navy Act?AnswerQ&A
The war effort is delayed by roughly the same interval because the act funded not only ships but also the yards and industrial capacity needed to build and sustain the fleet.
- 2:05:18QuestionWhat were the worst design mistakes of the two world wars?AnswerQ&A
The Royal Navy's steam-powered K-class submarines are the panel's clearest First World War choice, while the Second World War offers several contenders rather than one uncontested failure.
- 2:09:35QuestionWhy do some new anti-submarine frigates omit VL-ASROC?AnswerQ&A
A roughly twelve-nautical-mile torpedo delivery range offers too little advantage over helicopters and other weapons to justify a scarce launch cell, though a much longer-ranged successor could change that calculation.
- 2:14:55Operation Matterhorn's India-China supply chain and nuclear-security problemNotable Point
The B-29 could reach Japan through China, but the fuel, transport, airfield, and weapon-security chain made that route a poor substitute for secure island bases.
- 2:28:24QuestionWould an LHD with an angled flight deck and catapults be a viable carrier for a small navy?AnswerQ&A
It can be built, but catapults, arresting gear, aviation support, and the well deck compete for the same limited volume and interfere with the helicopter operations that define an LHD.
- 2:33:36QuestionHow many people could a Nimitz-class carrier carry in an emergency evacuation?AnswerQ&A
About 10,000 may be possible without an air wing and with severe crowding, but sanitation, food, water, and voyage length become the real limits.
- 2:35:21QuestionWould a folding ski-jump improve a helicopter-capable aviation ship?AnswerQ&A
No. A ski-jump is a heavily loaded structural part of the flight deck, while a folding mechanism adds failure and alignment risks for little recovered space.
- 2:36:20QuestionWhat if the United States had not expanded merchant-ship production before entering the Second World War?AnswerQ&A
The Allies would face a serious transport shortfall because British orders, credit arrangements, and early yards helped create the industrial base that later produced Liberty ships.
- 2:40:51QuestionWhat is a good book on the Tribal class and other large British destroyer designs of the Second World War era?AnswerQ&A
The panel recommends Dr. Clarke's Tribal, Battle and Daring Class Destroyers as a readable history of the ships, their crews, and their service.
- 2:42:13QuestionCould Tirpitz have been used actively instead of remaining a deterrent in Norway?AnswerQ&A
Germany could delay Bismarck's sortie until Tirpitz was ready and send a larger raiding group, but Britain would assemble multiple battleships and carriers to destroy it.
- 2:45:07QuestionIf British defense spending rose to five percent of GDP, what three procurement changes would have the greatest impact?AnswerQ&A
Fix Army artillery and logistics, expand RAF tanking, patrol, and F-35 capacity, and restore Royal Navy support shipping while buying more of proven escort designs.
- 2:49:21QuestionCould Bismarck have passed through the Denmark Strait without detection?AnswerQ&A
Probably not: ice narrowed the passage to well under one hundred nautical miles, two radar-equipped cruisers patrolled it, and the Royal Navy knew it was Germany's favored route.
- 2:50:21QuestionWould Ruby be a suitable Royal Navy ship name in the modern era?AnswerQ&A
Yes. Ten Royal Navy ships have carried the name, most recently an Acon-class destroyer completed in 1910, though Ruby would likely appear within an R-name or gemstone naming scheme.
- 2:53:00QuestionWhat doctrine governs the relationship between carrier groups and amphibious groups?AnswerQ&A
The carrier group wins and protects theater access, while the amphibious group uses that sea control to place and sustain forces ashore.
- 2:55:04QuestionWas the Baltic Project the only viable maritime strategy for increasing pressure on Germany?AnswerQ&A
The long blockade remained the core strategy, and entering the Baltic was the only direct way to close Germany's remaining maritime outlet, but it first required neutralizing the High Seas Fleet and controlling submarine threats.
- 2:55:45QuestionWould more ships from Convoy PQ 17 survive if the order to scatter came 500 miles later?AnswerQ&A
Probably more would survive because the convoy would be nearer its destination and past part of the air and submarine threat, but summer daylight and the location of the dispersal still leave the merchants exposed.
- 3:02:08Why logistics, housing, and family support underpin military growthNotable Point
More equipment does not create a larger usable force unless Britain can supply it, recruit people, keep them, and support families through disruptive postings.
- 3:06:19QuestionHow would the Second World War change if every major navy used submarine snorkels widely?AnswerQ&A
Snorkels could save some boats forced to operate submerged, but adding them to existing designs would complicate exhaust, machinery, conning-tower arrangements, and construction schedules.
- 3:14:29QuestionHow serious was the freeboard problem on USS Monitor?AnswerQ&A
It was fundamental: monitors were not rough-water ships, and Monitor's loss in the Atlantic demonstrated the danger of taking such a low hull into an ocean sea.
- 3:16:15QuestionWould Scharnhorst and Gneisenau be more effective with nine 11-inch guns or six 15-inch guns?AnswerQ&A
The nine 11-inch guns better suit a surface raider, while six 15-inch guns become preferable if the ships are expected to fight in a battle line against capital ships.
- 3:17:39QuestionAre opposed amphibious landings obsolete, and what replaces them if they are?AnswerQ&A
No, but a sensible assault avoids the defender's main concentration, lands where limited resistance can be overwhelmed, and builds combat power ashore before striking the primary objective.
- 3:22:07QuestionWas HMS Dreadnought actually used as a warship, or did she merely begin a new era?AnswerQ&A
She served actively as a flagship in the Channel, but the German fleet avoided the theater she guarded, so she performed an important deterrent role without receiving a Jutland-style battle.
- 3:27:57QuestionWas Jackie Fisher a pacifist, and can his caution be compared with George McClellan's wartime hesitation?AnswerQ&A
Fisher hated war and sought to deter it through overwhelming strength, but once fighting began he favored rapid, decisive action rather than McClellan-style delay.
- 3:29:27QuestionWhat was the best nuclear-powered guided-missile cruiser operated by the United States Navy?AnswerQ&A
Dr. Clarke chooses USS Long Beach because she was the last American cruiser hull designed from the outset as a guided-missile ship, despite her boxy superstructure.
- 3:31:01QuestionWhy did Lion and Queen Mary omit a superfiring turret rather than the amidships turret used in earlier layouts?AnswerQ&A
The machinery arrangement made that hull position more valuable for boilers, turbines, gearboxes, and shorter propeller shafts.
- 3:35:15QuestionWhy did the West German Navy operate land-based Starfighters and Tornados during the Cold War?AnswerQ&A
They were high-speed, low-level maritime strike aircraft intended to attack the Soviet Baltic Fleet, not carrier aircraft duplicating the air force.
- 3:36:58QuestionCould the Royal Navy deploy farther into the Pacific early in the Second World War?AnswerQ&A
It could reinforce from the Eastern Fleet, but Allied basing and competing threats made it sensible for Britain to lead in the Atlantic, Mediterranean, and Indian Ocean while America led in the Pacific.
- 3:42:41QuestionWhat is the panel's view of Britain's proposed Multi-Role Support Ship?AnswerQ&A
Its flexibility is attractive, but a light raiding concept may not carry the equipment or mass that Royal Marines need when they must fight as an infantry brigade in a peer war.
- 3:49:21QuestionHow would the late-1945 United States Navy demonstrate force if the country and its infrastructure were transported back to the Barbary Wars without using nuclear weapons?AnswerQ&A
Its carrier, battleship, amphibious, and Marine forces would overwhelm every contemporary power, allowing the United States to destroy the Barbary states' military capacity and dictate wider terms.
- 3:54:10QuestionWhy are Royal Marines and United States Marines so difficult to eliminate even when facing unusual threats?AnswerQ&A
Their raiding mission requires practiced withdrawal from superior forces, so survival, disengagement, and adaptation are trained skills rather than improvised reactions.
- 3:55:45QuestionHow much better were officers' quarters and food in the Age of Sail?AnswerQ&A
Their chief advantage was personal space; preserved food and drink were often much the same as the crew's, and purchased extras did not last long.
- 3:57:32QuestionDo new Type 45 upgrades show that the Type 83 successor program is being pushed back?AnswerQ&A
Not necessarily. Type 83 will take years in any case, so fitting Type 45 for current threats is required even if the successor remains on its expected development path.
- 3:58:58QuestionWas Tirpitz the only ship hit by a Tallboy bomb?AnswerQ&A
No. Tirpitz was struck in two operations, Admiral Scheer was also hit, Lutzow was attacked and damaged by a near miss, and Tallboys used against U-boat pens may have caught submarines inside.
- 4:00:55QuestionWhat Battle of Midway book would suit an eight-year-old already fascinated by the battle?AnswerQ&A
The Battle of Midway, edited by Thomas C. Hone, is recommended here when an adult can read its short self-contained chapters with the child and discuss them.
- 4:07:14QuestionWould a wartime-constrained Hood refit mainly replace her weapons?AnswerQ&A
Weapons could be changed relatively quickly; the real reconstruction required years to replace turbines and machinery, and Britain could not spare Hood from operational commitments for that long.
- 4:09:44QuestionWhat problems would Atlantic convoys face if Bismarck survived her 1941 sortie?AnswerQ&A
One successful raid would hurt a few convoys, but the greater problem would be a repaired Bismarck in France acting with Scharnhorst, Gneisenau, and Tirpitz and forcing Britain to disperse heavy covering forces.
- 4:13:41QuestionWould NATO send a carrier strike group along Russia's northern sea route to attack gas infrastructure?AnswerQ&A
Probably not. Land-based bombers can reach fixed infrastructure more easily, while attacking the icebreakers could close a route that is already seasonal and difficult.
- 4:15:43QuestionHow often did German surface raiders meet battleships while attacking convoys, and what happened?AnswerQ&A
When raiders recognized a battleship escort such as an R-class ship, they normally broke off rather than risk crippling damage for the chance to reach the merchants.
- 4:17:55QuestionDoes modern diesel-electric or direct-electric propulsion make naval hydrofoils more viable?AnswerQ&A
Not by itself. The persistent problem is finding a mission that values their speed enough to accept small size, rough-weather limits, and a narrow operating envelope.
- 4:19:00QuestionHow would a reconstructed HMS Tiger deployed before Operation Rheinübung change the Denmark Strait battle?AnswerQ&A
Tiger could add a third British capital ship, improve the maturity of 14-inch gunnery, and force the Germans to fight both Bismarck and Prinz Eugen under pressure from the opening salvos.
- 4:23:15QuestionHow much larger would the Royal Navy need to be to support six Invincible-class carriers?AnswerQ&A
Six task groups imply roughly fourteen or fifteen Type 42 destroyers and eighteen to twenty-four frigates, plus a larger amphibious fleet and successor program.
- 4:26:55QuestionHow widely did warships carry doctors?AnswerQ&A
Age-of-Sail ships carried practical surgeons rather than university physicians; later cruisers and larger ships generally had doctors, while destroyer flotillas concentrated a surgeon in the leader and used medics aboard individual ships.
- 4:34:03QuestionWhy did navies move from helicopter cruisers to helicopter carriers, and could the cruiser return?AnswerQ&A
Helicopter carriers add amphibious capacity, while modern escorts distribute helicopters across the fleet and reduce the need for a dedicated helicopter cruiser.
- 4:36:27QuestionWhat technical and political changes could have made HMS Captain safe while she was still on the stocks?AnswerQ&A
The hull needed to be lengthened, widened, and raised for stability and freeboard, which amounted to a major redesign that Captain's political champions would have had to accept.
- 4:37:31QuestionDoes the commissioning of Italy's Trieste create pressure for Britain to build two more large aviation or amphibious ships after the Type 26 program?AnswerQ&A
Not directly, because Trieste is an LHD and Britain would build that type in different yards from the frigate line; the larger constraint is preserving specialized industrial capacity and a workable deployment-refit cycle.
- 4:38:48QuestionWhy do newer British frigates use Mark 41 vertical launch cells while Type 45 destroyers use Sylver?AnswerQ&A
Type 45 inherited the European Sylver air-defense system from the Horizon program, while Mark 41 offers newer frigates broader weapon compatibility and attractive quad-packing options.
- 4:44:02QuestionWhere would the Deutschland class be used in a fleet action?AnswerQ&A
The answer depends on which class is meant: the interwar heavy cruisers should avoid the battle line, while the older German pre-dreadnoughts could stand at its rear to add gunfire.
- 4:44:39QuestionIf the Royal Navy had built six Invincible-class carriers, when would the class be fully retired?AnswerQ&A
The last ships would likely leave around the replacement of HMS Ocean and the arrival of three Queen Elizabeth-class carriers, but a larger Harrier force could delay the exact date.
- 4:45:14QuestionWhy did Russia and India adopt STOBAR carrier operations?AnswerQ&A
India adopted a Russian-supplied system that suited its fleet, while Russia valued rapid launches and recovery of heavier fighters for fleet air defense.
- 4:46:42QuestionWhat could Japan do with resources saved by avoiding topweight problems and later ship reconstructions?AnswerQ&A
The result depends on whether Japan still falsifies treaty displacement: honest designs lose some desired capabilities, while continued deception permits more ambitious but risky ships.
- 4:48:49QuestionCould Italy have improved quality control and infrastructure before the Second World War, and what would investment from the 1920s change?AnswerQ&A
Yes, but it required sustained money and political commitment; early infrastructure investment compounds over time, while the notorious main-caliber dispersion problem involved more than simple factory inspection.
- 4:50:14QuestionDoes a shortage of crews make a much larger naval reserve especially important?AnswerQ&A
Yes. Regular personnel may carry the opening weeks, but a long war needs trained reservists to expand the fleet and replace exhausted, wounded, or killed crew members.
- 4:51:14QuestionWhich British battleship design of the 1930s was the greatest missed opportunity?AnswerQ&A
The panel chooses the Lion class, while also noting the opportunity to arm the King George V class with a developed 15-inch weapon.
- 4:52:36QuestionIf HMS Tiger had been built to the A2 design, how likely was she to survive the London Naval Treaty?AnswerQ&A
A faster, more powerful Tiger would be more attractive to retain, though her survival would still depend on treaty limits and the alternatives the Royal Navy chose to discard.
- 4:55:41QuestionIf navies return to very large surface-warfare ships, what would they call them if not battleships?AnswerQ&A
Official language would probably favor cruiser or large surface combatant, with the final label shaped as much by budgets and rivalry as by the ship's weapons.
- 4:57:17QuestionHow far can automation reduce a warship's crew while retaining an adequate safety margin?AnswerQ&A
The technical minimum is less important than how much damage control, maintenance, casualty tolerance, and system integration a navy is willing to surrender.
- 5:00:06QuestionDid navies consider having flying boats land with convoys and refuel at sea to cover the mid-Atlantic air gap?AnswerQ&A
They considered related ideas, but range, launch and recovery, refueling, maintenance, and the need for sufficiently calm water made routine convoy-side operation impractical.
