  1. 4:00
    Ben-my-Chree in a wartime Fleet Air Arm song

    A Fleet Air Arm song used a rhymed pronunciation of Ben-my-Chree that remained in one naval-aviation family even after the ship's proper pronunciation was known.

    Notable Point
  2. 7:21
    Why archive access limited the book's scope

    COVID-era restrictions blocked planned Canadian archive work and hoped-for Australian research, so the book limited those sections to material the author could support directly.

    Notable Point
  3. 12:16
    The treaty loophole behind small carriers

    Treaty definitions explain why sub-10,000-ton carriers promised aviation capacity outside national carrier tonnage limits.

    Chapter
  4. 15:14
    Why the Royal Navy rejected very small carriers

    Royal Navy experience favoured medium-sized carriers numerous enough for global commitments over weak small carriers or a few very large ships.

    Notable Point
  5. 16:31
    Why 10,000 tons also became the cruiser ceiling

    The cruiser limit reflected fears that rivals might build powerful ships capable of supporting the battle line, although Jutland had made Britain wary of second-line ships in that role.

    Notable Point
  6. 18:30
    Why cruiser and carrier roles conflicted

    American studies kept mixing gun-cruiser and carrier requirements even as exercises showed that carriers worked best as protected aviation centers.

    Chapter
  7. 21:13
    Royal Navy exercises defined a carrier's escort

    Exercises normally placed at least a light cruiser and four destroyers around each carrier, making Glorious's two-destroyer escort an exception to established practice.

    Notable Point
  8. 22:06
    Kongō modernization points toward carrier task groups

    Work on the Kongō class and planned super cruisers reflected Japan's shift toward fast surface escorts for carrier formations.

    Notable Point
  9. 22:45
    John Collett's case for a flying-deck cruiser

    A 1934 proposal placed a flying-deck cruiser in each heavy-cruiser division to sustain scouting while preserving fleet carriers for air combat and strike missions.

    Chapter
  10. 26:26
    Why the hybrid inherited both ships' weaknesses

    Large aviation structures, limited fighter capacity, gun-line exposure, and incompatible maneuvering requirements undermined the flight-deck cruiser.

    Notable Point
  11. 29:02
    Fleet exercises had already exposed the hybrid's problem

    American, British, and Japanese exercise experience showed why a scout carrier placed in the cruiser line would inherit carrier vulnerabilities without enough aircraft to gain carrier strengths.

    Notable Point
  12. 31:12
    A more viable forward aviation ship

    A full-deck scout carrier with dual-purpose guns might have worked if designers abandoned cruiser combat power and acted before cruiser tonnage limits closed the opportunity.

    Notable Point
  13. 34:55
    Interwar aviation choices without hindsight

    Interwar planners could see aviation improving but could not safely assume its wartime trajectory or procure every experimental boundary as a fleet standard.

    Notable Point
  14. 36:37
    Ryūjō's treaty-driven design and stability problems

    Japan built Ryūjō as a fast, long-ranged light carrier, but the effort to fit 48 aircraft into a treaty-light hull produced serious stability problems.

    Chapter
  15. 39:10
    Ryūjō's practical 1942 air group

    By August 1942 Ryūjō carried 24 Zeros and nine B5N torpedo bombers, enough for patrol and a limited strike but below her advertised capacity.

    Chapter
  16. 40:54
    Japan's choice between stronger strikes and more flight decks

    Scarce aircraft forced Japan to choose between concentrating stronger air groups on fewer carriers and sending more flight decks to sea with weakened complements.

    Notable Point
  17. 43:47
    Ryūjō's Henderson Field strike drains its air group

    Six B5Ns and 15 Zeros attacked Henderson Field, but Marine and Army fighters reduced the returning force to 14 aircraft, including only two torpedo bombers.

    Chapter
  18. 46:58
    Enterprise finds Ryūjō and Saratoga sinks her

    Enterprise scouts located the detached Japanese force, and Saratoga's larger air group delivered the bomb and torpedo hits that sank Ryūjō.

    Chapter
  19. 49:42
    Why small carriers were pushed into fleet-carrier work

    When no larger flight deck was available, a small carrier was likely to receive fleet-carrier missions beyond its air-group and survivability limits. A gun-heavy hybrid faced similar pressure to fight as a cruiser.

    Notable Point
  20. 51:04
    A 1924 flight-deck-cruiser counterfactual

    The closing thought experiment asks how Congress and rival navies would react if the United States put an aviation hybrid into every cruiser division in 1924-25.
