Study Bruships 117: Battle Cruisers, Battle-Cruisers or Battlecruisers?, a Dr. Alex Clarke video from 16 Jul 2023, with 70 time notes. Topics include Battlecruisers, Live Q&A, Naval Aviation.
Time notes
- 1:50QuestionWould the original Admiral-class battlecruiser design have been more useful than the modified ship?AnswerQ&A
An unchanged ship would be less useful; a larger standardised group could have supported more substantial interwar rebuilding.
- 7:18QuestionWhat might a 'super Renown' built for the Second World War look like?AnswerQ&A
Its form would turn on senior designers' priorities, especially speed, calibre, and turret arrangement.
- 8:23QuestionShould Japan have scrapped the KongÅ class during the interwar years?AnswerQ&A
No; treaty constraints made refit the practical choice, potentially through a very extensive reconstruction.
- 9:57Why 100 Martlets would have matteredNotable Point
A hypothetical stock of 100 Wildcats would help fill the Royal Navy's missing generation of effective naval fighters.
- 13:45QuestionWhy did Britain not use pound currency in every colony?AnswerQ&A
Some colonies used sterling, while others adopted readily available dollar currencies whose history long predated the United States dollar.
- 15:54QuestionWould one hundred Brewster Buffalo fighters help the Royal Navy in 1939?AnswerQ&A
Yes; they could serve as an adequate interim naval fighter until 1941 despite the type's later reputation.
- 19:19QuestionWhat if the Royal Navy had adopted diesel for ships and aircraft after the First World War?AnswerQ&A
Logistics might improve, but achieving the required speed would require an expensive fleet-wide engineering programme.
- 20:37The lost opportunity of a rebuilt TigerNotable Point
A rebuilt Tiger could have offered a fast 14-inch-gun capital ship while the Royal Navy waited for newer construction.
- 23:55QuestionWas the Dido-class programme undermined by a belief that another war would never happen?AnswerQ&A
The argument is that leaders hoped to avoid war but expected more preparation time, not that they considered war impossible.
- 25:20QuestionWhat could an Allied navy realistically do with a captured Deutschland-class cruiser?AnswerQ&A
Use it for roles such as Arctic convoy escort or distant patrol, not for high-speed fleet work.
- 27:00QuestionWhat if the Queen Elizabeth class had been designed for 28 knots?AnswerQ&A
It could create a faster, more flexible battle squadron and compound German difficulties at Jutland.
- 28:19QuestionWhat if the United States remained the only country with atomic weapons?AnswerQ&A
It would gain exceptional power, but allied nuclear knowledge and the political cost of suppressing it would make the monopoly difficult to sustain.
- 32:34QuestionWithout a Washington-style treaty, how many battlecruisers might the British Empire build?AnswerQ&A
The Royal Navy would probably establish G3s first, then build successors for dominion fleets as fast global units became more important.
- 33:53Battlecruiser is a spectrum, not a fixed boxNotable Point
Vanguard and the Iowa class illustrate why battlecruiser and fast-battleship labels cannot be applied as rigid categories.
- 35:45QuestionIs there a place for battlecruisers in modern navies?AnswerQ&A
The term can still fit exceptionally large and powerful nuclear cruisers, even though their protection differs from historical battlecruisers.
- 36:57QuestionWhich navy would have the weakest carrier air wing if the Second World War began in 1942?AnswerQ&A
None is clearly worst; the outcome depends on how delayed war changes development and on how each mixed air group is employed.
- 42:03QuestionHow would Jellicoe have used a direct scouting report from Beatty during Jutland?AnswerQ&A
He would have welcomed it, while continuing to build his tactical picture from reports sent by other ships and commanders.
- 42:35QuestionWhy did Britain not extend nuclear power from submarines to more surface warships?AnswerQ&A
Surface ships need different reactor arrangements and a costly new industrial base, without a sufficiently strong requirement.
- 45:52QuestionWould a navalised Hawker Typhoon be worthwhile as a British carrier strike aircraft?AnswerQ&A
Probably not unless it displaced another type with a clear capability gain, because it did not meet the carrier group's dive-bomber or torpedo-strike needs.
- 47:10QuestionHow would a canal with Caledonian-style locks affect British naval operations in the War of 1812?AnswerQ&A
It could admit fifth-rate frigates, allowing the Royal Navy to reinforce with established ships rather than depending on local construction.
- 53:30Why a Taranto-style strike needs a worthwhile targetNotable Point
The case against a British carrier raid on Wilhelmshaven is the poor exchange between force risk and likely target value.
- 54:54QuestionWhat is the smallest useful autoloading main-battery calibre for a battle-line ship?AnswerQ&A
Eight inches remains too light against battleship protection, however high its rate of fire.
- 55:30How engine substitutions complicated the BarracudaNotable Point
Repeated engine changes altered far more than the Barracuda's powerplant and made its development problems harder to interpret.
- 58:02QuestionIf a treaty signatory lost a battleship by accident, did it have to build a replica?AnswerQ&A
No; accidental-loss clauses allowed a new replacement design.
- 1:01:53QuestionIs it reasonable to doubt the projected 35-knot performance of the O-class battlecruiser?AnswerQ&A
Yes; both displacement and speed should be treated as optimistic design claims rather than proven performance.
- 1:03:26QuestionWould a British 15-inch/50 gun have reused ammunition from the 15-inch/42?AnswerQ&A
Probably, provided the breech and mounting offered enough space.
- 1:08:52QuestionCould warships be designed so major refits never require cutting open the hull?AnswerQ&A
Only by accepting very large permanent access openings and internal routes, which impose space and protection penalties.
- 1:13:06QuestionDid Britain stop large-calibre naval-gun research after the Second World War?AnswerQ&A
No; research continued, but the navy needed carriers and other ships more than new battleships.
- 1:17:59Reading Hood through crew memory and Prince of Wales's damageNotable Point
An introductory Hood history combines crew recollections with a concise account of why Prince of Wales broke off and what the action did to both sides.
- 1:24:29QuestionHow might cruiser development change without interwar displacement limits?AnswerQ&A
Heavy cruisers would grow and perhaps adopt 9.2-inch guns, while fast six-inch light cruisers would still fill a separate role.
- 1:31:46How late-war magazine lessons changed the Admiral classNotable Point
A lower magazine promised faster protective flooding after underwater damage, but the revision could not solve the wider limits of Hood's design.
- 1:32:54Separating battlecruiser design from ammunition and gunnery failuresNotable Point
A book discussion separates hull protection from British propellant, flash-safety, shell, and shooting problems when comparing battlecruiser losses.
- 1:39:38QuestionHow might a Theodore Roosevelt presidency in 1920 change the naval treaty landscape?AnswerQ&A
Naval limitation might still occur, but through a less restrictive and differently structured treaty system.
- 1:42:51QuestionHow could the Royal Navy dispose of old ships while keeping shipbuilding industry sustainable?AnswerQ&A
Replace a consistent share of retired ships, because scrapping alone sustains breakers rather than builders.
- 1:45:20Speculatores, exploratores, and Roman special operationsNotable Point
Roman scouting bodies developed different tactical and strategic intelligence roles, though the surviving names and boundaries remain contested.
- 1:56:55QuestionWhen would treaty-free navies recognise their older 13.5-inch and 14-inch battlecruisers as liabilities?AnswerQ&A
Probably in the late 1920s, once new fleets were dominated by 15-inch and larger guns.
- 1:59:57QuestionHow would the war change if the United States concentrated on Japan rather than Germany?AnswerQ&A
Britain could blockade and contain Germany, but major European invasions would be delayed while Allied strength concentrated on Japan.
- 2:05:17How the large light cruisers became carrier experimentsNotable Point
Ships conceived for Fisher's Baltic project proved ill-suited as gun platforms but supplied hulls for early carrier development.
- 2:14:04QuestionWhat would treaty ships designed 'fitted for but not with' hidden wartime capacity look like?AnswerQ&A
They could reserve structural and machinery space for rapid additions of guns, armour, boilers, and shafts.
- 2:15:23QuestionWhy did Soviet, Italian, and German battleships retain mixed secondary batteries while other navies adopted dual-purpose guns?AnswerQ&A
Separate batteries appeared to maximise each role, whereas dual-purpose guns required a compromise those procurement cultures disliked.
- 2:19:26Operation White and the cost of inadequate range marginNotable Point
A carrier reinforcement flight to Malta failed when headwinds consumed a plan with too little margin for weather and pilot experience.
- 2:29:38QuestionWhat might the Royal Navy gain if interwar air policy placed less emphasis on strategic bombing?AnswerQ&A
Most clearly, an effective dedicated dive bomber would probably arrive earlier.
- 2:32:43QuestionWhat minimum surface force would make a submarine-focused German navy more credible?AnswerQ&A
Pairs of long-range, fast 11-inch-gun raiders would force cruisers to avoid them and disperse heavier British protection.
- 2:37:20Choosing between narrative and technical battlecruiser historiesNotable Point
Different battlecruiser books serve different study goals: technical plans, narrative history, or a focused ship biography.
- 2:50:47QuestionHow would an Allied Italy affect Germany and Japan in the Second World War?AnswerQ&A
Germany would face a vulnerable southern flank, while Britain could move much of its Mediterranean naval strength toward the Indian Ocean and Japan.
- 2:54:02QuestionWhich Royal Navy ships might it have been better not to acquire?AnswerQ&A
Several notorious classes are candidates, but a flawed ship that filled a necessary role should usually be replaced by a better design rather than simply omitted.
- 2:59:31QuestionWhat changes if the Royal Navy subcontracts more escort construction to American yards before 1940?AnswerQ&A
The plan faces legal, standards, and capacity barriers because the United States was foreign and many later wartime yards were not yet available.
- 3:04:13QuestionWould buying RMS Olympic in 1935 for conversion into an auxiliary aircraft carrier make sense?AnswerQ&A
It would produce an interesting carrier, but the old liner's machinery and reboilering needs would make the conversion expensive.
- 3:09:13QuestionWere four G3s and four N3s enough to match the planned American and Japanese capital-ship programmes?AnswerQ&A
They were an initial five-year programme, likely followed by successor groups rather than Britain's final answer to the arms race.
- 3:11:57QuestionWhich Royal Navy weapon mounting most needed redesign?AnswerQ&A
The 4.7-inch dual-purpose mount needed elevation of roughly 80-85 degrees to become an effective anti-aircraft weapon.
- 3:12:46QuestionHow could Nelson and Rodney use their unused treaty displacement most effectively?AnswerQ&A
Improve the 16-inch gun and add machinery for a third shaft, potentially raising speed to roughly 28 knots.
- 3:16:29QuestionHow would an N-class destroyer fare against a Fletcher-class destroyer?AnswerQ&A
The N class may have a slight gunfight edge, but Fletcher's larger torpedo battery remains a major threat.
- 3:22:03QuestionHow reliable is the chief engineer's account of what happened to Shimakaze?AnswerQ&A
As reliable as corroboration and internal logic make it; firsthand memory alone is not conclusive.
- 3:23:02QuestionWhat is the earliest destroyer that could defeat HMS Dreadnought one-on-one?AnswerQ&A
A radar-equipped night fighter could do it, with some well-trained interwar British destroyers also having a plausible torpedo opportunity.
- 3:23:58QuestionWithout naval treaties, how long would earlier British capital ships remain in service?AnswerQ&A
Sustained new construction would move them into reserve and likely remove the 15-inch generation by the late 1930s.
- 3:26:50Why modern destroyers build more like capital shipsNotable Point
Modern destroyer production is constrained by cruiser-like roles and capital-ship levels of systems complexity.
- 3:29:01The American debate over Britain's shipbuilding capacityNotable Point
American planners had to separate Britain's ability to build major warships from political assumptions about whether its economy could fund them.
- 3:31:34QuestionWhy did the Royal Navy not adopt the trimaran warship concept after RV Triton?AnswerQ&A
Its extra volume did not justify the infrastructure and construction cost for the roles Britain required.
- 3:33:19QuestionWhy did British plans for Taranto not include RAF bombers?AnswerQ&A
The planning began before suitable bombers could be assumed, and no RAF bomber squadron was based within useful range when the raid occurred.
- 3:35:24Why the Littoral Combat Ship problem began with its missionNotable Point
The Littoral Combat Ship inherited frigate missions under a new label, exposing a requirements problem before hull form became the issue.
- 3:38:50QuestionWhat if River-class frigates had been built instead of Flower-class corvettes?AnswerQ&A
They would be more capable and easier to upgrade, at the cost of larger hulls and longer construction.
- 3:45:51QuestionWhat engineering limits govern the choice between a heavier shell and a higher-velocity naval gun?AnswerQ&A
Velocity brings barrel length, wear, weight, and manufacturing penalties, so calibre, shell mass, rate of fire, and ammunition capacity must be balanced together.
- 3:57:45QuestionWhy choose a 57 mm gun for Type 31 rather than a larger 76 mm weapon?AnswerQ&A
Because the 57 mm better fits a heavy-flak role, while 76 mm is the stronger general-purpose choice.
- 4:02:14QuestionHow difficult would it be to make a Zumwalt-class gun use standard army 155 mm shells?AnswerQ&A
It is technically possible but operationally unattractive, because a naval system can use a larger, more effective projectile than soldiers can handle manually.
- 4:09:09QuestionWhy did Britain fit Bofors 40 mm guns to ships instead of standardising on CTA 40?AnswerQ&A
Bofors was the proven, low-risk off-the-shelf choice, while naval CTA 40 was not mature enough for the programme's approach.
- 4:12:43QuestionWould the United States need faster Lexingtons to compensate for its slow battle line?AnswerQ&A
No; Lexington was intended to scout and hunt cruisers while the concentrated battleship force closed for a decisive action.
- 4:18:29QuestionWhy is military doctrine often unclassified?AnswerQ&A
Because announcing the intended mission does not reveal the detailed methods, training, and capability needed to carry it out.
- 4:22:49QuestionHow did American planners address the lack of nearby bases in a hypothetical war with Britain?AnswerQ&A
They considered Irish support and planned to invade Canada, but reliable basing near Britain remained doubtful.
- 4:25:24QuestionHow powerful would a combined Grand Fleet and British Pacific Fleet be?AnswerQ&A
With the Grand Fleet upgraded for 1945 combined operations, it could be the era's most powerful fleet and make an invasion of Japan more feasible.
- 4:31:16QuestionWhat might Japan build if it remained in the treaty system instead of constructing Yamato?AnswerQ&A
Probably an Iowa-like 16-inch battleship that claimed a much lower standard displacement than it actually had.
