    QuestionWhat are the panel's thoughts on the current state of the U.S. Navy's fast replenishment oiler auxiliary force?Answer

    The U.S. Navy does not have enough fast replenishment oilers, and useful designs are not being built quickly enough.

    Q&A
  2. 2:04
    QuestionHow would the world react if Japan built Musashi and Yamato in the First World War, but they were 24-knot ships without radar?Answer

    Other navies would be petrified by battleships of that scale appearing in the First World War.

    Q&A
  3. 2:17
    QuestionWould a 10,000-to-12,000-ton Royal Navy cruiser with six 6-inch guns and twelve 3-inch guns trade its forward 76 mm mount for six Exocet launchers after four 3-inch guns were replaced by Sea Cat?Answer

    The ship would probably keep the forward 76 mm mount because a hull that large should have other deck space for Exocet launchers.

    Q&A
  4. 4:38
    QuestionWhat happens if Warspite is held in reserve and remains available for later reactivation?Answer

    Assuming Warspite had avoided severe salt erosion, she would probably be reactivated after the Falklands. VLS and helicopter facilities would improve her usefulness as a command ship alongside four 15-inch guns.

    Q&A
  5. 6:29
    QuestionWould it have been economical for the Soviet Union to build an interwar line of heavy cruisers derived from Rurik II?Answer

    Probably not. The necessary industrial infrastructure would make the idea uneconomical, even though the Soviets would continue pursuing other cruiser types.

    Q&A
  6. 7:03
    QuestionWhat would the U.S. Navy look like if Congress stayed obsessed with Jeune Ecole ideas from the 1890s to 1920, and could it recover in time for the Second World War?Answer

    Recovery would be theoretically possible, but very difficult. Rebuilding industrial capacity would leave the United States needing experienced heavy-warship engineers, while decades without a battle fleet could also change its overseas position.

    Q&A
  7. 7:16
    The capital-ship expertise lost under Jeune Ecole

    Decades without battleship construction would leave the United States short of the engineers, yards, and accumulated experience needed for a rapid 1930s naval expansion.

    Notable Point
  8. 8:41
    How a weak U.S. battle fleet changes the Pacific balance

    Without battleships and overseas force projection, the United States could lose its historical Pacific position, leave Japan dominant after Britain, and lack the leverage behind the Washington treaty system.

    Notable Point
  9. 10:30
    Battlecruisers as the high end of Jeune Ecole doctrine

    A Jeune Ecole U.S. Navy might adopt battlecruisers for commerce warfare, then interpret Jutland according to how firmly it remained attached to the doctrine.

    Notable Point
  10. 13:19
    QuestionWhat does the panel think of the Vondetan-class battlecruiser from Halo reference material?Answer

    It is a true battlecruiser concept: battleship-grade firepower on a cruiser-derived hull, formidable on paper but fragile under sustained wartime punishment.

    Q&A
  11. 14:26
    Replacing two heavy MACs with one super MAC

    The Vondetan's planned two-gun battery becomes one super magnetic accelerator cannon, so gun count alone understates the change in firepower.

    Notable Point
  12. 14:30
    Missile quality versus magazine depth on the Vondetan class

    Seventy Archer pods provide roughly 2,100 missiles in place of fifty more capable Ares weapons, while six Shiva tubes retain a nuclear option.

    Notable Point
  13. 16:52
    The Vondetan as a self-contained expeditionary warship

    Aircraft, landing craft, vehicles, drop pods, troops, and a year of stores make the fictional battlecruiser an expeditionary platform as well as a gun-and-missile combatant.

    Notable Point
  14. 18:17
    Armor thickness versus compartmentation in Halo warships

    The Vondetan's uneven armour and disputed relationship to the Valiant raise questions about internal protection, while Everest's exceptional feats complicate the comparison.

    Notable Point
  15. 23:52
    Vanguard, treaty limits, and the meaning of fast battleship

    An argument about Vanguard's classification compares her subdivision with the treaty-era King George V design and asks what changes when treaty restrictions disappear.

    Notable Point
  16. 25:46
    QuestionIf HMS Incomparable had been built, would she be overbuilt for cruiser killing but useful for gunboat diplomacy?Answer

    Incomparable would be an intimidating gunboat-diplomacy symbol, but her cost, docking demands, and oversized 20-inch armament would also make her a conspicuous white elephant.

    Q&A
  17. 28:48
    How Incomparable could disrupt naval limitation

    A single spectacular British battlecruiser could encourage prestige competition and make historical naval-limitation bargains harder to sustain.

    Notable Point
  18. 31:16
    Refitting Incomparable for radar-controlled gunnery

    A 1930s refit and radar fire control could turn Incomparable's slow-firing 20-inch guns from an unreliable spectacle into a credible long-range threat.

    Notable Point
  19. 32:32
    QuestionHow much could 1930s boilers improve Incomparable over her original machinery?Answer

    A major improvement is expected, although no numerical gain is calculated. The original proposal used Yarrow boilers for 180,000 shaft horsepower.

    Q&A
  20. 35:33
    A radar-controlled Incomparable at Denmark Strait

    An imagined radar-directed Incomparable at Denmark Strait threatens Bismarck with 20-inch salvos, although the same arms race could also change the German opponent.

    Notable Point
  21. 36:52
    A carrier-battlecruiser hunting group for Incomparable

    Incomparable's need for air cover and ammunition support leads to a proposed carrier-battlecruiser team for hunting surface raiders.

    Notable Point
  22. 39:10
    Why radar ranging changes the gunnery problem

    Optical rangefinders provide a band that spotting salvos must refine, while radar supplies the range and bearing data needed to train the guns directly.

    Notable Point
  23. 40:02
    QuestionCould Incomparable realistically carry twelve 18-inch guns?Answer

    Nine 18-inch guns in three triple mountings are considered plausible. Twelve would need a different arrangement, such as quadruple 16-inch or 15-inch/50 mountings, with greater mechanical complexity.

    Q&A
  24. 42:39
    QuestionWhere did the British quadruple-turret designs come from?Answer

    Vickers and Armstrong were both studying quadruple turrets, with French designs prompting British interest.

    Q&A
  25. 43:30
    Full plate armour in shipboard fighting

    A family-history account connects lighter protection at sea with movement on confined decks and the danger of falling overboard in full plate.

    Notable Point
  26. 44:18
    Fitted plate armour, layered protection, and breathing

    An argument about fitted breastplates combines layered protection with a panelist's experience of flat armour restricting breathing.

    Notable Point
  27. 46:22
    Ceremonial armour as status and intimidation

    A comparison of feminine breastplates and enlarged codpieces shows how elite armour could exaggerate the wearer's silhouette for status and intimidation.

    Notable Point
  28. 48:51
    Why six 20-inch guns are poor for pre-radar ranging

    A proposed twelve-gun arrangement would allow alternating ranging salvos before turning broadside, exposing the limits of Incomparable's six slow-firing 20-inch guns.

    Notable Point
  29. 52:02
    Jadwiga of Poland in armour

    Jadwiga, king of Poland from 1384 to 1399, is the ruler cited in the discussion of women wearing fitted plate armour in battle.

    Notable Point
  30. 52:56
    Elizabeth I, delegated command, and Catherine of Aragon

    Elizabeth I coordinated forces on several fronts, while the comparison with Henry VIII and Catherine of Aragon separates personal generalship from a monarch's wider responsibilities.

    Notable Point
  31. 1:04:05
    Why a French landing near Newcastle looked impractical

    A proposed French landing near Newcastle is criticized through its beaches, routes, and local resistance, with the Welsh landing used as a comparison.
