Time notes

  1. 1:49
    How the Service Squadron projected naval power

    The 1923-24 Service Squadron paired battlecruisers with five long-range D-class cruisers to display Royal Navy reach and warn rivals that their trade was vulnerable.

    Chapter
  2. 4:47
    The firepower behind the Service Squadron display

    Each of the five D-class cruisers carried twelve 21-inch torpedoes, six 6-inch guns, and one-inch magazine protection, giving the diplomatic display real combat weight.

    Notable Point
  3. 6:05
    Dauntless and Delhi on station and flagship duty

    Dauntless's long repair interrupted station coverage, while Delhi served as Eighth Cruiser Squadron flagship in the Caribbean and called at Panama.

    Notable Point
  4. 8:30
    Mediterranean duty and New Zealand replacements

    Despatch served with Third Cruiser Squadron in the Mediterranean as Spanish Civil War commitments grew, while Achilles and Leander replaced Diomede and Dunedin in New Zealand.

    Notable Point
  5. 12:03
    The unrealised anti-aircraft cruiser refit

    Interwar plans called for four twin 4.5-inch mounts on each D-class cruiser, an ambitious anti-aircraft conversion that weapons development could not deliver before the war.

    Chapter
  6. 16:09
    How Spanish Civil War duties delayed modernization

    Recalling cruisers for the Spanish Civil War consumed the peacetime availability that a thorough D-class refit would have required.

    Notable Point
  7. 18:32
    Why useful cruisers missed their overhaul

    Worldwide commitments kept the D class in service, and even a two-ship force could not guarantee one fully ready hull while the other was in refit.

    Chapter
  8. 21:37
    Northern Patrol work and the hunt for Graf Spee

    Dragon and Diomede carried the early-war patrol burden, and Dragon's search for Admiral Graf Spee exposed a lightly armed cruiser to a dangerous possible encounter.

    Notable Point
  9. 24:15
    Delhi's conversion and Despatch at Mulberry

    Delhi's American conversion created a modern Force H anti-aircraft cruiser, while Despatch moved from Cape Spartivento to headquarters duties for the Mulberry harbours.

    Notable Point
  10. 26:05
    A class spread across British shipbuilders

    British yards divided construction of the D class, while four cancelled names reveal the administrative choices behind an unfinished class.

    Notable Point
  11. 27:48
    Durban's final role as a Mulberry blockship

    New Crown Colony and Dido cruisers ended the case for overhauling Durban, whose hull instead became a blockship in the Normandy harbour defences.

    Notable Point
  12. 28:38
    ORP Dragon's Polish service and Normandy loss

    The Polish Navy operated Dragon on Home Fleet, convoy, and Normandy duties before damage off the invasion coast turned her into another Mulberry blockship.

    Chapter
  13. 30:08
    Why the Polish cruiser became ORP Conrad

    Danae's Polish name, ORP Conrad, honoured the writer Joseph Conrad after other proposed city names proved politically unsuitable.

    Notable Point
  14. 31:11
    Dunedin's captures, Audacity, and loss

    Dunedin captured vessels carrying an Enigma machine and the future HMS Audacity before U-124 sank the cruiser with heavy loss of life.

    Chapter
  15. 32:43
    The D class in global presence missions

    Long station service and repeated wartime adaptations kept the D class useful, with Danae and Delhi surviving in service until 1948.
