Study UAD: 18in gun Agincourt & Other Ideas, a Dr. Alex Clarke video from 28 Feb 2023, with 34 time notes. Topics include Battleship Design, German Battleship Bismarck, HMS Agincourt.
Time notes
- 2:29Inspecting the Queen Elizabeth MaximusChapter
The opening inspection establishes a British maximum design with 16.5-inch main guns and rapid-firing 4.5-inch secondaries.
- 5:01Building Germany's maximum 1912 counterpartChapter
The opposing German design is rebuilt around plausible guns, armour, speed, and the physical limits imposed by the Kiel Canal.
- 7:01Restoring a plausible German torpedo and gun batteryNotable Point
The autogenerated opponent is stripped of deck torpedoes and an anachronistic mixed battery in favor of German underwater tubes and a rational dreadnought armament.
- 12:19QuestionWhy is the German design heavier to port than to starboard?AnswerQ&A
An extra gun had been placed on the port side; identifying and correcting it restored the design's balance.
- 15:08Fire control and the Kiel Canal shape the German maximumNotable Point
Advanced German rangefinding is retained, but a narrow canal-limited hull and roughly 24-knot target constrain the design.
- 20:57Scaling speed and armour for a maximum Queen ElizabethNotable Point
The British design balances a 28- to 29-knot target with battleship-grade protection scaled for 16.5-inch guns.
- 24:33Why British and German capital ships divergedNotable Point
British global commitments and German North Sea priorities produce different trade-offs in speed, armour, and naval spending.
- 28:55A turret explosion turns the first trial into a survival testNotable Point
The first battle shows how a lost turret, depleted ammunition, flooding, and exposed casemates can overturn an otherwise tough battleship design.
- 41:10Redesigning protection and secondaries after the failed trialChapter
The failed battle drives a redesign of barbette protection, secondary armament, anti-aircraft guns, speed, and the German opponent's survivability.
- 44:08Six-inch secondaries and three-inch anti-aircraft gunsNotable Point
The revised British ship uses six-inch secondaries against torpedo threats and adds the three-inch anti-aircraft weapons common to the period.
- 49:47When historical battleship designs meet game AINotable Point
The stream uses UAD as a design experiment while separating historical plausibility from campaign-optimal choices.
- 50:44Preserving main-battery arcs around the secondariesNotable Point
The revised secondary battery is checked against the heavy turrets' fields of fire before the layout is accepted.
- 52:16Georgios Averof and the speed of a mixed fleetNotable Point
A background image prompts a brief lesson on how Georgios Averof's speed let the Greek flagship leave its slower fleet and operate independently against the Ottomans.
- 57:20Why Skoda triple turrets strain the German counterfactualNotable Point
A twelve-gun German ship requires access to Skoda triple turrets that institutional pride made unlikely to be adopted historically.
- 58:43The trade-off between 16.5-inch and 18-inch gunsNotable Point
A 16.5-inch battery may be more attractive than an 18-inch battery when rate of fire and firepower are weighed together.
- 1:03:59Small-calibre hits expose the fire-control systemNotable Point
Repeated 3.4-inch hits damage fire control and prompt a wider redesign of towers, beam, and secondary armament.
- 1:11:49HMS Furious exposes the game's 18-inch-gun gapNotable Point
HMS Furious proves that Britain's 18-inch gun already existed even though UAD's 1920 technology tree withholds it from the design test.
- 1:15:08QuestionCould the design use larger torpedoes?AnswerQ&A
Not within this 1920 game setup: it caps the design at 20 inches, even though British and German navies historically used 24-inch torpedoes.
- 1:17:42QuestionAre there mods that could add the missing technology?AnswerQ&A
Possibly, but this test avoids them so it remains standardized and repeatable with the same game setup.
- 1:18:30Why six-inch secondaries transform the UAD fightChapter
Adding a strong six-inch secondary battery solves a game problem created by UAD's close-range AI, which differs from real dreadnought tactics.
- 1:27:12Scaling armour for an 18-inch AgincourtChapter
An imagined modernized Agincourt receives 18-inch guns and a protection scheme derived from British Queen Elizabeth-era ratios.
- 1:32:20QuestionWould the modernized 18-inch Agincourt still carry torpedoes after its refit?AnswerQ&A
Probably not. The extensive refit removes the torpedoes in favor of the revised secondary arrangement.
- 1:32:44Giving Agincourt a Warspite-style modernizationNotable Point
After removing torpedoes, the hypothetical refit adopts a Warspite-style 4.5-inch secondary battery and redistributes protection and weight.
- 1:36:29German limits in an 18-inch-gun worldChapter
The opposing Bismarck-like design is constrained by German infrastructure, industrial capacity, and historically plausible armament choices.
- 1:43:40Testing Bismarck's speed, range, and canal limitsNotable Point
Trial speed, realistic cruising range, and Kiel Canal dimensions keep the enhanced Bismarck within German operating constraints.
- 1:49:43The narrow range window favoring the Bismarck-like shipNotable Point
The Bismarck-like opponent has a small range band in which its 15-inch guns can engage before Agincourt's 18-inch battery can answer.
- 1:53:17Why one battle doctrine cannot fit every naval eraNotable Point
A close-range attack that suits pre-dreadnought combat becomes self-defeating when the same AI applies it to long-range dreadnoughts.
- 2:01:48Trading shell weight for interwar gun rangeNotable Point
Lighter shells extend the hypothetical 18-inch battery's range while protection remains heavy, echoing Nelson and Rodney's long-range priorities.
- 2:02:48QuestionWould it help if players could choose the AI captain's attack strategy?AnswerQ&A
Yes. Selectable strategy would help because manually coordinating the ship, watching the enemy, and managing the action is difficult to do all at once.
- 2:08:39An 18-inch Agincourt against a Bismarck-like opponentNotable Point
The matchup illustrates the destructive potential of an 18-inch battery, while emphasizing the need to maintain range.
- 2:13:46How an 18-inch prewar flagship could reshape the naval raceNotable Point
Even a single Royal Navy ship with eight 18-inch guns before the First World War would force other navies to reconsider their own capital-ship plans.
- 2:14:55Reconstructing Yamato for the comparisonChapter
Yamato is recreated as a modern battleship with historically informed speed, 18.1-inch guns, armour, and secondary armament.
- 2:31:12Four twin turrets or three triples?Notable Point
The Agincourt-Yamato test compares four twin 18-inch turrets with three triples while acknowledging major differences in mass, speed, and range.
- 2:36:47Range advantage cannot remove magazine riskNotable Point
The final trials show why a long-range advantage still depends on avoiding close action and surviving magazine hits.
