Time notes
- 7:59QuestionCould the Alaska class have used a different bow form to make it stronger?AnswerQ&A
Yes, although the issue was buoyancy and seakeeping rather than structural weakness; the design prioritized a long, high-speed hull form.
- 8:52QuestionWhat is the light carrier in the photograph with Missouri and an Alaska-class cruiser?AnswerQ&A
The accompanying description identifies it as the escort carrier USS Croatan and also lists several destroyers in the scene.
- 10:13QuestionWere the Tiger-class light cruisers a terrible idea?AnswerQ&A
No. The concept and six-inch autoloaders had promise, but the class was too small and its systems were not made to work reliably enough.
- 13:44QuestionHow do Alaska's secondary-armament and aircraft arrangements compare with Iowa's?AnswerQ&A
Both were effective for their intended roles, but Iowa was bounded by the Panama Canal while Alaska was bounded by the heavy-cruiser concept.
- 14:54QuestionWhy did so many cruisers carry four-inch guns?AnswerQ&A
They were useful against merchant ships and could also hurt many lightly armoured protected cruisers of the period.
- 15:31QuestionWhat refit might have improved the Tiger-class light cruisers without removing most of their anti-aircraft armament?AnswerQ&A
A redesigned layout could have exchanged selected turrets for Sea Dart and Sea Cat while retaining guns and adding lighter weapons.
- 17:20QuestionWhich Pacific Fleet commander warned against keeping the fleet at Pearl Harbor but still received some blame for the later posture?AnswerQ&A
Admiral James O. Richardson, who protested the basing policy and wanted the fleet returned to the West Coast.
- 19:46QuestionHow much of Iowa's extra width over Alaska was used for torpedo protection and bulkheads?AnswerQ&A
A large amount, together with the space demanded by Iowa's heavier armour.
- 23:48QuestionHow difficult was it to maintain sails and rigging on warships converted to steam power?AnswerQ&A
It was a real problem, but many ships normally sailed and used their engines only when needed, limiting continuous soot exposure.
- 24:15QuestionWas Hood the first fast battleship?AnswerQ&A
No. Hood retained battlecruiser arrangements, while a true fast battleship also combines speed with battleship-level protection and subdivision.
- 26:00QuestionWere Hood's crushing tubes for torpedo protection filled with water or air?AnswerQ&A
Both arrangements were explored at different points; he recalls water-filled tubes in at least one configuration but treats the exact sequence cautiously.
- 26:48QuestionDid aircraft carriers camouflage their flight decks, and could the paint disguise the ship from aircrew?AnswerQ&A
They used some camouflage, but it was limited so that landing and operating markings remained visible.
- 28:41QuestionWhich national archives have useful online access for naval research?AnswerQ&A
US and UK collections are improving, but reciprocal arrangements with researchers near local archives remain useful for material that is not online.
- 29:43QuestionHow would an Alaska-class cruiser fare against a Deutschland-class ship?AnswerQ&A
Alaska would hold a decisive advantage and would probably sink the Deutschland-class ship very quickly.
- 29:52QuestionHow might Royal Navy battlecruisers have regarded the Alaska class?AnswerQ&A
As a worthy opponent: Alaska could have heavier armour, but the British battlecruisers generally carried larger guns.
- 30:23QuestionWith more time and money, would the Iowa class have been redesigned to resemble Alaska more closely?AnswerQ&A
Possibly in some respects, but other design requirements and infrastructure limits would still have kept the ships distinct.
- 32:38QuestionCould the projected sixth Queen Elizabeth-class ship have been the first fast battleship?AnswerQ&A
Yes, if small-tube boilers had enabled about 28 knots while preserving the class's battleship characteristics.
- 33:42QuestionIf you could own and preserve any large warship, which would you choose?AnswerQ&A
HMS Renown, because she would fill the absence of a surviving British capital ship while remaining more manageable than some alternatives.
- 35:29QuestionDo you have a favourite naval camouflage scheme?AnswerQ&A
Yes, a 1944-era Arctic camouflage pattern used on destroyers.
- 36:30QuestionWhy did the Tiger-class light cruisers carry an amidships three-inch turret?AnswerQ&A
It increased anti-aircraft coverage, allowing at least several mounts to engage from most approach angles.
- 39:10QuestionWhat might happen if naval treaties allowed each major power a class of 45,000-ton battleships?AnswerQ&A
The powers would probably build whole classes of larger capital ships, prompting an international cycle of enlarged designs rather than a single exceptional vessel.
- 42:01QuestionDid Hood's Queen Elizabeth-like armour scheme make her as strongly protected as a Queen Elizabeth-class battleship?AnswerQ&A
No. The maximum thickness could be similar, but it did not cover the same share of the hull.
- 44:57QuestionWould replacing late-war vessels one-for-one with their pre-war versions improve their performance?AnswerQ&A
Probably not, because late-war radar and other upgrades were important parts of the ships' combat value.
- 46:58QuestionWhy would battlecruisers be a poor match for Italian battleships in the Mediterranean?AnswerQ&A
Their survivability relied heavily on manoeuvre, and Mediterranean waters offered less room to exploit that advantage.
- 47:33Why tonnage alone does not define a cruiser or battlecruiserNotable Point
Warship categories changed while designs grew, so a tonnage treated as heavy-cruiser scale in one era could describe a light cruiser in another.
- 48:58QuestionCould HMS Tiger, if armed with fourteen-inch guns, take on a Kongo-class battlecruiser?AnswerQ&A
Yes. The heavier-gunned Tiger could fight a Kongo-class ship without undue difficulty.
- 49:55QuestionCould a purpose-built ram have changed an early ironclad battle such as Hampton Roads?AnswerQ&A
Potentially, but an effective ram required the whole hull to be shaped and strengthened for the collision.
- 50:26QuestionHow would small-tube boilers across the Royal Navy affect the Harwich Force and Jutland?AnswerQ&A
They could make the Grand Fleet markedly faster, restoring Dreadnought's usefulness and giving British battlecruisers and destroyers still greater mobility.
- 52:01QuestionCould an armoured conning tower keep its occupants safe from a direct battleship-calibre hit?AnswerQ&A
Not reliably. Shock and vibration could disable the occupants, and nearby follow-up hits could cause catastrophic damage.
- 52:50QuestionHow would the United States react if a British-German-Japanese alliance defeated and dismembered France?AnswerQ&A
Concern would centre on the resulting two-ocean threat, pushing the United States toward either accommodation or major rearmament.
- 54:53QuestionWhat might the unbuilt Leopard-class battlecruiser have looked like?AnswerQ&A
Probably much like HMS Tiger with fifteen-inch guns, although the after-turret layout would depend on related design developments.
- 57:54QuestionWould a larger Bismarck-class battleship be trapped in the Baltic if it could not use the Kiel Canal?AnswerQ&A
Not necessarily, but it would have to use the Danish exits or Germany would need to widen the Kiel Canal.
- 59:09QuestionAre sea trials crewed by shipyard staff or the ship's future crew?AnswerQ&A
Usually by a mixture of builder staff, naval assessors, and some personnel who will form the ship's first crew.
- 1:00:04QuestionWhat would small-tube boilers do for Royal Navy pre-dreadnoughts?AnswerQ&A
They might reach about 19 or 20 knots, but hull form and the rest of the machinery would prevent a much larger gain.
- 1:01:13QuestionDid any Tribal-class destroyer besides Haida receive its own book?AnswerQ&A
Not as a separate modern treatment, but a 1957 class history offers approximately one chapter per destroyer.
- 1:02:46QuestionWhat Royal Navy ship types were workhorses but receive less attention than famous classes?AnswerQ&A
Examples include 13.5-inch dreadnoughts, Renown, Crown Colony and Arethusa cruisers, Hunt destroyers, U-class submarines, and escort carriers.
- 1:06:09QuestionIf France and Germany alone went to war in May 1941, how might their navies fight?AnswerQ&A
Expect a North Sea clash and French efforts to hunt down Deutschland-class commerce raiders around the world.
- 1:07:00QuestionDid sailing warships take precautions against lightning, and were ships ever lost to it?AnswerQ&A
Some precautions existed, while wood and caulking offered natural insulation; possible lightning losses are known, though no example is identified here.
- 1:08:43QuestionHow would British control of the Panama Canal influence Royal Navy ship design and deployment?AnswerQ&A
Ships would be designed to use both Suez and Panama, allowing two-way imperial movement while giving Britain leverage over a vital US route.
- 1:09:55QuestionWho commanded the largest pirate fleet in history?AnswerQ&A
A highly capable Chinese woman pirate leader, although the exact name is uncertain in this exchange.
- 1:10:24QuestionWhich navies nearly chose the alternative to their familiar wartime 40 mm anti-aircraft weapon?AnswerQ&A
The United States nearly chose the pom-pom, while Britain nearly chose the 40 mm Bofors.
- 1:11:24QuestionWhy did British battlecruisers suffer magazine explosions?AnswerQ&A
They were often used in battle-line conditions that constrained their designed advantage of high-speed manoeuvre.
- 1:12:09QuestionHow much would history change if British and American naval anti-aircraft systems were swapped?AnswerQ&A
The balance between volume of fire and longer-range accuracy would shift, affecting individual actions more than overall campaign results.
- 1:13:46QuestionDid Britain have a follow-on aircraft design to replace the Sea Vixen?AnswerQ&A
Yes, improved Sea Vixen derivatives were studied, but the Phantom was judged the more cost-effective choice.
- 1:15:39QuestionWould a superpower Royal Navy have developed an equivalent to the Ticonderoga class?AnswerQ&A
Very likely, as a radar-centred air-defence cruiser probably closer to an enlarged Bristol concept than a direct copy.
- 1:16:57Chasing the fall of shot in Royal Navy manoeuvre doctrineNotable Point
Royal Navy ships could manoeuvre toward the observed fall of an enemy salvo, changing course before the opponent's correction arrived.
- 1:17:30QuestionHow would Royal Navy design evolve if every destroyer or larger ship had to carry a triple six-inch turret?AnswerQ&A
Destroyers would suffer a severe weight penalty, while the mandate would probably accelerate development of a triple six-inch autoloader for larger ships.
- 1:20:25QuestionWhat would Churchill winning the 1945 election mean for the armed forces and Royal Navy?AnswerQ&A
Most policy might remain similar, but carrier spending could shift toward large new ships instead of extensive reconstruction of wartime hulls.
- 1:21:02QuestionWhich revisionist interpretations of Royal Navy history are most irritating, and can revisionism be useful?AnswerQ&A
Revision is useful when new evidence warrants it; the problem is judging past actors solely by present-day standards.
- 1:27:32QuestionWhen did military and civilian maritime infrastructure diverge, and could a dreadnought share a dock with a liner?AnswerQ&A
They could share docks; the key difference was that naval yards served emergency fleet needs while civilian yards had to sustain commercial workloads.
- 1:28:22QuestionWhen did torpedoes become viable anti-submarine weapons?AnswerQ&A
In the late 1940s; earlier successes occurred, but dependable use required homing technology and less reliance on luck.
- 1:29:47QuestionWhy was HMS Dreadnought so influential if warship design was already heading in that direction?AnswerQ&A
She was the first to cross the threshold and instantly became the standard against which every battleship was compared.
- 1:30:37QuestionWhat damage would a modern heavyweight torpedo do to a Second World War battlecruiser?AnswerQ&A
It would detonate beneath the keel and try to break the ship's back, though keel damage is not invariably an immediate sinking.
- 1:32:24QuestionHow many modern torpedo hits would it take to sink a Queen Elizabeth-class battleship?AnswerQ&A
One would do serious damage, two might sink her, and three would make the loss much more certain, depending on hit location and damage control.
- 1:32:55QuestionWhy was the all-main-gun concept first associated with battleships rather than tested on an armoured cruiser?AnswerQ&A
Some armoured cruisers were already close to the concept; the Duke of Edinburgh class is his example of the transition.
