The 18in Gun HMS Agincourt and UAD video comment response (Long Patrol)
Study The 18in Gun HMS Agincourt and UAD video comment response (Long Patrol), a Dr. Alex Clarke video from 18 Mar 2022, with 28 time notes. Topics include Alternate History, Battlecruisers, Battleships.
Time notes
- 1:40An 18-inch Queen Elizabeth alternativeNotable Point
An imagined modernised Queen Elizabeth-type battleship carries six 18-inch guns into a simulated duel with a Bismarck analogue.
- 4:09QuestionWhy do all-forward designs struggle to place boilers and engines far enough aft?AnswerQ&A
The concentration of forward armament constrains the available internal arrangement; moving funnel and machinery spaces helps, but a real hull would need tailored changes.
- 4:48QuestionWhat do the displayed results show about the ship's secondary guns?AnswerQ&A
This report credited larger guns, but four-inch batteries have been effective in other engagements and cannot be judged from one display alone.
- 5:45QuestionWhat might a 1918 start to the First World War have meant for British 12-inch dreadnoughts?AnswerQ&A
Most would probably have been replaced, transferred, or relegated because the Royal Navy was already moving toward much heavier-gun ships.
- 6:47QuestionDoes UAD produce higher hit rates than historical naval gunnery achieved?AnswerQ&A
Not necessarily; equipment choices such as radar can change the simulation, so one battle's accuracy should not stand in for historical rates.
- 8:21How 18-inch British ships could reshape naval treatiesNotable Point
An operational British 18-inch battleship could have influenced Hood's armament, the Nelson class, and the calibre allowances negotiated into later naval treaties.
- 8:58Why two knots may not be enough to cross the TNotable Point
A two-knot advantage does not automatically let a battle line cross an opponent's T, while three or four knots offers more tactical freedom.
- 10:11QuestionWhy judge Troubridge and Arbuthnot differently when Troubridge held an independent command and Arbuthnot only led a squadron?AnswerQ&A
Troubridge's freedom was limited by direction from London, while Arbuthnot acted with less effective supervision and might have benefited from senior intervention.
- 11:30QuestionShould a battleship rely on its main battery against cruisers and leave lesser targets to its own fleet?AnswerQ&A
Fleet roles matter, but combat is untidy: secondaries address likely secondary threats when escorts are absent or cannot keep them away.
- 14:17The size and accuracy of the 18-inch experimentNotable Point
The simulated Agincourt records 25 per cent main-gun accuracy and displaces about 39,000 tons, around 5,000 tons above the quoted Queen Elizabeth-class figure.
- 15:37A Baden-Bayern approximation with 14-inch gunsNotable Point
A German battleship inspired by Baden and Bayern uses triple 14-inch guns because UAD's 1916 technology set does not yet offer the historical 15-inch calibre.
- 16:44QuestionHow should designers weigh four-, five-, and six-inch secondary batteries?AnswerQ&A
The choice balances rapid engagement, shell effect, mounting availability, expected targets, and whether a navy can afford specialised weapons.
- 19:11Why the simulated British battle line has more shipsNotable Point
The Royal Navy receives roughly two-to-one or four-to-three superiority to represent the numerical advantage expected in a battleship action.
- 20:08QuestionWhy can the design not simply use a 4.5-inch secondary battery?AnswerQ&A
The limiting factor is the lack of a suitable upper-deck mounting, not the existence of the 4.5-inch gun itself.
- 20:49QuestionAre French battlecruiser designs too speculative to include alongside other unbuilt capital ships?AnswerQ&A
No; some French proposals were at least as plausible as the unbuilt super-ships commonly explored for other major navies.
- 22:06QuestionWould the E3 armoured cruiser have been a cruiser killer in the way Tiger was intended to hunt battlecruisers?AnswerQ&A
Yes; its 9.2-inch and six-inch armament, speed, and protection form a package designed to defeat cruiser-sized opponents.
- 23:01QuestionHow should Tiger's reported speed be interpreted?AnswerQ&A
Trial figures may exceed normal sea-going performance, so tactical planning should use the speed expected in service.
- 24:37QuestionWhat design trade-off came with British wire-wound naval guns?AnswerQ&A
They were strong, but the construction method added weight and made savings elsewhere in the ship more valuable.
- 25:04QuestionWas HMS Tiger designed primarily as a battlecruiser hunter rather than a conventional cruiser-killer?AnswerQ&A
Yes. Tiger's layout, machinery, and six-inch armament fit a purpose of engaging enemy battlecruisers more closely than the earlier distant-station role.
- 31:14QuestionWhy use standard rather than heavy shells in UAD?AnswerQ&A
In this model, heavier shells tend to worsen barrel wear, accuracy, or displacement, so standard shells give a more reliable compromise.
- 32:00A faster Tiger would push later battlecruisers harderNotable Point
A 30- or 32-knot Tiger would pressure later battlecruisers to become faster and widen the competition over speed.
- 32:28QuestionDoes UAD provide exact templates for historical warships?AnswerQ&A
No; it is largely build-your-own, but near-equivalent components can still illustrate the important design choices without exact replicas.
- 36:28QuestionWould one British squadron against one German squadron represent the battle both navies wanted?AnswerQ&A
Not really; each side wanted favourable concentration, with Germany seeking an isolated British force and Britain seeking to exploit its overall numerical superiority.
- 39:37QuestionCould torpedo mounts help an early capital ship counter an opponent crossing the T?AnswerQ&A
No. Torpedo ranges in the early dreadnought period were too short for that manoeuvre.
- 40:55All-forward layouts can simplify hull designNotable Point
Concentrating triple turrets forward can let designers organise the hull efficiently around known machinery, magazine, and armament zones.
- 42:21Command succession after a flagship is lostNotable Point
After Hibernia sinks, the simulation leaves the chain of command and the successor flagship unclear.
- 43:27All-forward armament and the pursuit manoeuvreNotable Point
An all-forward battery can let a ship turn onto an enemy's stern while keeping its own guns bearing, but it also creates firing-arc limits and vulnerable blind spots.
- 47:17Internal and deck-mounted capital-ship torpedoesNotable Point
Replacing an internal torpedo chamber with deck mountings recovers hull space but leaves exposed explosives that require careful siting and protection.
