Study Bruships: A Special - Questions/What If's till the Bru runs out?, a Dr. Alex Clarke video from 2 May 2021, with 73 time notes. Topics include Alternate History, Live Q&A, Naval Aviation.
Time notes
- 4:34QuestionDid warships ever win a battle by looking like civilian ships?AnswerQ&A
Pulo Aura reversed the premise: armed merchantmen looked enough like warships to bluff a stronger French squadron into retreat.
- 6:40QuestionWhat missions do Western navies perform besides sea control, including work such as icebreaking?AnswerQ&A
Those missions make sea control useful by protecting commerce, opening routes, and enabling supplies and forces to move.
- 18:21QuestionWhat woods were preferred for wooden warships, and did the choice change by ship type?AnswerQ&A
British yards normally used oak; emergency construction might use fir, and Indian yards could use excellent but expensive teak.
- 20:49QuestionWhich had the greatest effect on the Battle of the Atlantic: HF/DF, hunter-killer groups, escort carriers, long-range aircraft, or mass cargo-ship production?AnswerQ&A
Escort carriers had the greatest individual effect, with long-range aircraft and HF/DF close behind and mass production enabling the wider system.
- 25:51QuestionCould Britain and Canada win the Battle of the Atlantic without the United States entering the war?AnswerQ&A
Probably, if Japan also stays out; Canadian production and a narrower war make victory plausible, but likely later.
- 27:09QuestionWould a few carrier fighters have been enough to save Force Z?AnswerQ&A
They might have, because disrupting a coordinated air attack could make its individual elements much easier for the ships to evade or repel.
- 30:25From Kongo experience to the Japanese-designed Fuso classNotable Point
The Fuso class could draw on knowledge gained from the British-built Kongo while still expressing Japan's own developing naval intelligence and design practice.
- 32:11QuestionHow long would it take to convert a large container ship into an anti-submarine helicopter platform?AnswerQ&A
A useful British conversion might take about a month, but the time depends on whether it must merely land helicopters or sustain a full squadron.
- 33:41QuestionHow could NATO have created a mothball system to preserve more Cold War gun-armed ships for future use?AnswerQ&A
Keep selected ships in a sheltered warm-water reserve, protect their exposed systems, and avoid removing equipment that would slow reactivation.
- 34:30QuestionWas deploying Force Z a mistake?AnswerQ&A
The force itself was defensible, but its forward placement was not; an Indian Ocean base would have made it a stronger mobile deterrent.
- 36:16QuestionWithout American aid to the Soviet Union, could Germany shift more forces against Britain in 1942 or 1943?AnswerQ&A
Probably not soon; Soviet offensives would slow, but German logistics and manpower would still bind major forces to the Eastern Front.
- 36:58QuestionWould Dutch neutrality let Japan keep buying East Indies oil and avoid invading the colony?AnswerQ&A
Probably not; Japan's material shortages and imperial ambitions still pointed toward taking control of the Dutch East Indies.
- 37:16QuestionWhy is the Battle of the Atlantic called a battle rather than a campaign?AnswerQ&A
Mostly because the name works; in operational terms it was a campaign and, more broadly, an entire theater.
- 37:41QuestionHow would carrier attacks change if the angled flight deck appeared in 1940?AnswerQ&A
Operations would become faster and safer, but the change assumes accompanying advances in landing aids, engines, and aircraft.
- 39:18QuestionDid merchant ships or warships ever feign damage to ambush a commerce raider?AnswerQ&A
Yes; British Q-ships pretended to be damaged merchantmen so submarines would approach their concealed guns.
- 40:02QuestionWhat if the Royal Navy adopted 14-inch guns in place of its 13.5-inch dreadnought weapons?AnswerQ&A
The later fleet might move to 16-inch guns sooner, giving the Queen Elizabeths, Revenges, and Nelsons a more standardized armament family.
- 43:13QuestionHow did British authorities react to Jutland, and how did national interpretations differ?AnswerQ&A
Britain mostly believed it had won strategically, despite disappointment over the incomplete tactical result; other navies drew different lessons.
- 44:04QuestionHow much would an Allied victory in Norway weaken the Battle of the Atlantic?AnswerQ&A
It could weaken it dramatically by turning the North Sea into an Allied air barrier between German yards and French Atlantic bases.
- 47:01QuestionHow would the absence of radio and radar change Second World War naval combat?AnswerQ&A
Reconnaissance, long-range attack, and fleet coordination would collapse toward visual, local control despite otherwise modern ships and aircraft.
- 48:34QuestionShould HMS Tamar's new dazzle paint scheme raise an eyebrow before her Indo-Pacific deployment?AnswerQ&A
Yes; several navies were reviving visual camouflage for regional deployments because it could still complicate an opponent's visual acquisition.
- 51:41QuestionWhat caused Royal Navy stagnation between the Seven Years' War and the American War of Independence?AnswerQ&A
A generational turnover combined with seniority rules that kept talented junior officers from replacing weaker seniors during peace.
- 53:15QuestionCould better preparation, including bomber attacks on Japanese airfields, have changed the defense of Singapore?AnswerQ&A
The more decisive preparation was to man the pillboxes protecting Singapore's water supply so the garrison was not forced to surrender for lack of water.
- 58:50QuestionCould Finland control the Baltic Sea in a war with Russia?AnswerQ&A
Probably not; both sides could contest and use the Baltic, but control would remain local rather than theater-wide.
- 59:25QuestionWhat if Josephus Daniels allowed the US Navy to arm its Standard-type battleships with 16-inch guns after 1913?AnswerQ&A
It would accelerate the international caliber race, likely producing British 16-inch ships sooner and making 18-inch treaty designs far more plausible.
- 1:01:56QuestionWhy did the Allies not make a second attempt to take Norway after the United States entered the war?AnswerQ&A
Because an entrenched German force in Norway's difficult terrain would make a renewed invasion disproportionately costly and complex.
- 1:04:26QuestionHow well did navies study earlier wars before the world wars, and did new technology make those lessons obsolete?AnswerQ&A
They studied them seriously, and lessons such as the Royal Navy's focus on night fighting still paid off despite technological change.
- 1:04:52QuestionWhy did the Royal Navy build only one HMS Unicorn-style aircraft support ship?AnswerQ&A
Unicorn was an experimental first step, and her support role was subsequently carried into light fleet carriers such as Pioneer and Perseus.
- 1:07:24QuestionWhat could the modern German Navy do if sent back to the Battle of Jutland?AnswerQ&A
Its sensors and precision weapons could disrupt British command and tip the fight, but it probably could not sink the armored battle line by itself.
- 1:14:02QuestionWhat if the Anglo-Japanese Alliance continued beyond its historical end?AnswerQ&A
Britain and Japan could form an exceptionally strong global naval partnership, but the United States would work hard to divide it.
- 1:17:28QuestionWhat if the United States retained 14-inch guns for its Second World War battleships?AnswerQ&A
The ships could be smaller or, more likely for the US Navy, substantially faster because less weight and space would be devoted to guns and ammunition.
- 1:18:47QuestionHow exactly was HMS Glorious lost, and what decisions allowed it to happen?AnswerQ&A
Glorious left the main force and was caught after her captain failed to maintain the standard air patrol that could have warned of the German battlecruisers.
- 1:22:19QuestionIf the Iowa class had stayed in reserve rather than returning during the 1980s, would the US Navy reactivate the ships now?AnswerQ&A
Probably not without a major engine overhaul and extensive work to reverse decades of deterioration.
- 1:25:25QuestionWhat would another few months of peacetime construction do for the Royal Navy if war began in spring 1940?AnswerQ&A
It would likely add carriers and escorts while bringing the King George V and Lion programs substantially closer to operational strength.
- 1:29:58QuestionHow should the Royal Navy redeploy in mid-1942 if every German and Italian capital ship has been neutralized?AnswerQ&A
Keep limited home and Mediterranean covering forces, then mass the remaining carriers, battleships, and submarines at Ceylon for operations against Japan.
- 1:39:06QuestionHow would the Atlantic war change if Germany fielded Type XXI submarines in late 1942 or 1943?AnswerQ&A
Allied anti-submarine work would become much harder and more resource-intensive, but the Type XXI would not automatically restore decisive German success.
- 1:40:46QuestionIf a modern German squadron struck every British bridge at Jutland, could the surviving officers hold the line or press on to victory?AnswerQ&A
The fleet could retain command, but whether Beatty or Jellicoe survived might determine how aggressively it continued the battle.
- 1:46:36QuestionIf a navy could have only battleships or battlecruisers, which should it choose?AnswerQ&A
Battleships, because cruisers can cover many battlecruiser missions while no smaller type fully replaces a fast, heavily protected capital ship.
- 1:48:14QuestionHow large would a battleship need to become for 18-inch guns, and what makes 20-inch weapons difficult?AnswerQ&A
Probably more than 50,000 tons for an 18-inch ship; 20-inch guns magnify barrel, handling, and structural problems sharply.
- 1:50:07QuestionWas there a role for a new Royal Navy eight- or 9.2-inch cruiser in the 1940s and early postwar period?AnswerQ&A
Yes; a 9.2-inch cruiser could provide the heavy hitting power, carrier escort, and presence absent from Britain's mainly six-inch cruiser fleet.
- 1:51:37QuestionWould modern Type 212 submarines dominate the British battle line if sent to Jutland?AnswerQ&A
They could be lethal from a prepared ambush, but speed endurance, weapon limits, target suitability, and coordination make the result highly dependent on where they begin.
- 1:55:35QuestionWhat long-term effect would a modern German fleet sent back to the First World War have on engineering and ship development?AnswerQ&A
It would cause a massive technical leap, but reproduction limits and Imperial Germany's political choices would determine whether that knowledge stabilized or destabilized Europe.
- 2:00:14QuestionHow would the war change if Denmark, Norway, Sweden, and Finland formed an alliance on 2 September 1939?AnswerQ&A
A mobilized Nordic armed-neutrality bloc could make German invasion much harder and would probably receive British and French support.
- 2:02:48QuestionWhat would happen if a British cruiser squadron were visiting Pearl Harbor during the Japanese attack?AnswerQ&A
The cruisers would be attacked too, but their radar watch and warnings might give ships in the harbor a better chance to prepare and fire back.
- 2:04:25QuestionWhat would the Royal Navy look like if the First World War never happened?AnswerQ&A
It would build many more 15-inch battleships and probably move to heavier guns, while naval aviation matured much more slowly without wartime pressure.
- 2:07:29QuestionDo battleships aim at a point or a line segment when firing at a moving target?AnswerQ&A
They calculate the future point where the target should be when the shells arrive, using mechanical fire-control computers to update the solution.
- 2:16:39QuestionHow would different warships deal with a direct hit from a Schwerer Gustav railway-gun shell?AnswerQ&A
They probably would not survive the hit; the serious uncertainty is whether the railway gun could strike a moving ship at all.
- 2:20:20QuestionNavies often build economical ships, so why object to a less capable battleship such as the Revenge class?AnswerQ&A
Cheap mass escorts can create useful numbers, but a handful of capital ships must each deliver the full capability their battle-line role requires.
- 2:27:52QuestionWas the Alaska class a battlecruiser or a large cruiser?AnswerQ&A
It was best understood as the last armored cruiser, enlarged from cruiser lineage rather than cut down from a battleship.
- 2:29:03QuestionHas aircraft technology slowed if a 1981 pilot could understand an F-35 more easily than a 1941 pilot could understand an F-14?AnswerQ&A
The basic aircraft remains recognizable, but the F-35's engine, cockpit, sensors, and helmet conceal changes that its silhouette does not show.
- 2:31:55QuestionHow far could China push in the South China Sea before other states said enough?AnswerQ&A
There was no knowable fixed threshold; a naval incident could activate national and allied responses that politics then made difficult to de-escalate.
- 2:41:40QuestionAfter Sicily, how would you conduct the Allied invasion of Italy?AnswerQ&A
Risk a landing near Genoa to cut across northern Italy, isolate German forces farther south, and avoid fighting through every prepared line on the peninsula.
- 2:44:57QuestionWhat would be your ideal Second World War surface action group?AnswerQ&A
Lion-class battleships backed by Tribal and Fletcher destroyers, Atlanta anti-aircraft cruisers, Town-class cruisers, and Alaska-class heavy support.
- 2:46:56QuestionHow close can a 15-inch shell land without hitting and still be dangerous?AnswerQ&A
Close is dangerous for a destroyer, disturbing for a cruiser, and usually survivable for a battleship.
- 2:48:24QuestionIf the First World War did not happen and Argentina, Brazil, and Chile fought in the South Atlantic, who would come out on top?AnswerQ&A
Chile and Brazil would probably defeat Argentina, especially if Chile received its super-dreadnought and Brazil retained the Minas Geraes class.
- 2:53:48QuestionCould an internal solitary wave have contributed to the loss of the Indonesian submarine?AnswerQ&A
It was one possible mechanism discussed at the time, but the cause remained unknown pending evidence from the wreck and investigation.
- 2:58:47QuestionWhich was the best early-war Pacific carrier: Ark Royal, the Yorktown class, or the Shokaku class?AnswerQ&A
Shokaku was strongest by day, Ark Royal at night, and Yorktown the best all-round compromise.
- 3:07:47How historians reason when the archive is incompleteNotable Point
A conclusion can be logical within a narrow set of facts yet remain unproved when missing documents or unrecorded conversations hide part of the decision chain.
- 3:11:04Converting Hood's sisters instead of Courageous and GloriousNotable Point
A proposed study asks what carrier fleet Britain might obtain by completing Hood's sisters Anson, Howe, and Rodney as conversions instead of rebuilding Courageous and Glorious.
- 3:12:33QuestionHow deeply could a U-boat dive and still be detected by an aircraft using early magnetic anomaly detection?AnswerQ&A
Most U-boats could get below its useful range in deep water, but shallow choke points such as Gibraltar made the early system practical.
- 3:18:49QuestionWhat would a modern armored cruiser look like?AnswerQ&A
About 25,000 tons, heavily armed with missiles and guns, and possibly nuclear-powered to supply lasers and railguns.
- 3:23:14QuestionWere the Royal Navy's early carrier losses caused by stupidity, incompetence, or ship design?AnswerQ&A
Primarily by poor employment, command decisions, and damage control rather than a general failure of British carrier design.
- 3:32:57QuestionWhen did the US Navy begin using radio beacons to help aircraft navigate back to carriers?AnswerQ&A
The Royal Navy used them increasingly around 1936-37, and the US Navy followed not long afterward.
- 3:33:41QuestionWhat if Japan used Yamato and Nagato at Guadalcanal instead of Hiei and Kirishima?AnswerQ&A
The battle becomes larger and costlier, but logistics and the range of the night engagement mean an American victory remains possible.
- 3:36:28QuestionWhat if Japan used the Fuso and Ise classes for Tokyo Express bombardments instead of the Kongos?AnswerQ&A
They would bring heavier guns but spend longer exposed to attack and consume more fuel, making greater losses on both sides likely.
- 3:42:25QuestionDo militaries need a serious conflict periodically to prevent bureaucratic overreach?AnswerQ&A
No; realistic, unscripted exercises followed by honest analysis can expose and correct institutional failures without a war.
- 3:46:21QuestionDid Hitler intend to start the Second World War during the 1938 Czech crisis?AnswerQ&A
No; Hitler expected further concessions and misjudged the British and French commitment to Poland.
- 3:48:57QuestionWhat stance did France take during the Falklands War after selling Exocet missiles to both sides?AnswerQ&A
France assisted Britain by holding back important Exocet supplies from Argentina until after the war.
- 3:50:15QuestionIs there ever a case where using a warship to carry cargo is advantageous?AnswerQ&A
Yes; warships can be justified for compact, extremely valuable cargo that must get through quickly and securely.
- 3:51:02QuestionHow would Task Force 34 fare against the Japanese Center Force at the Battle off Samar?AnswerQ&A
It would probably win, most decisively in a radar-directed night action, but Japanese torpedoes could make the victory costly.
- 3:55:57QuestionWere Japan's severe carrier-aircrew losses caused more by ship design or by operating practice?AnswerQ&A
Primarily by operational doctrine, including how the carrier forces were grouped and the combat situations in which they were committed.
- 4:00:39How repeated high-explosive hits defeat armored shipsNotable Point
Armor does not make high-explosive fire harmless: blast strips exposed systems, injures crews, and repeated impacts can crack protection or overwhelm lighter ships.
- 4:04:28QuestionWhy do longer gun barrels produce higher muzzle velocity if expanding gas loses pressure as the shell travels down the bore?AnswerQ&A
Because the gas acts on the shell for longer, transferring more total energy even while its pressure gradually falls.
- 4:06:12QuestionWho wins if HMS Victorious and her battle group face Indonesian Badgers armed with anti-ship missiles in 1964?AnswerQ&A
Victorious has a chance if her Sea Vixens intercept before launch; a large missile salvo getting through would create severe problems for the group.
