00:06:25 – If Naval Codes were changed while a ship was underway, how would the ship captain know what the new codes to use were?

00:11:18 – How did the freedom of action granted by steam change battle tactics?

00:17:18 – In the event of an attack from the air by fighters as well as torpedo and dive bombers, what was the Japanese doctrine/strategy on the use of its complement of (presumably) spotter aircraft?

  1. You mention that Dudley Pound died of an undiagnosed brain tumor during WW2. Looking it up, apparently Roger Backhouse also died of a brain tumor. Which makes me wonder, was there something in the Admiralty that was causing brain cancer? That's a fairly unusual cause of death, and for it to take two First Sea Lords in a row seems quite odd. Did any other British admirals from this period also have brain tumors? Smoking certainly causes cancer, but that's normally in the lungs, not the brain.

  2. The British (and Australian) E class subs in WW1 had beam torpedoes inside the pressure hull and weren't that large for submarines.

    If you look at the diagrams they look extremely awkwardly placed and almost certainly have a very serious impact on maximum diving depth/structural integrity… All for not much gain.

    A single shot amidships is pretty lightweight.

  3. Biggest thing that creates a change in class is a redesign of a ship. Either classified as a new design by the government or the naval office in control of the ship.

    In the case of government or naval classification would be the US standard battleships, which had settle differences. The Ticonderoga class completely changed from arm launchers to vertical launchers. How many flights are there of the Aleigh Burke class is there? Go back to WWII, you had the Gearing class and Sumner class that was pretty much the same ship.

  4. A new class is defined by planning, logistics and training. If planners will need to separate two similar ships because their capabilities diverge sufficiently to notice at a tactical or strategic planning level = new class.

    If enough equipment is different that a bespoke spares and maintenance pipeline is required from other members of the same class = new class

    If crew transferring from a supposed sister ship need retraining to operate the new ship = new class

  5. I remember that four pack (of cigarettes) a day men were considers chain smokers. Google says typical cigarette is smoked over 5 minutes. Four packs of 20 makes for 80 cigarettes. 400 minutes is 6 2/3 hours a day smoking. He refers to five of six packs a day makes for 10 hours of having a lit cigarette on hand.
    My grandfather and his twin were semi chain smokers. One would have a lit cigarette, as his went out the other would pull out a pack to light up. I never saw both smoking at the same time, but one or the other usually had a lit cigarette on hand.

  6. Related to the question about old munitions:

    At the end of WW2 the USN had over 100,000 20mm Oerlikons cannons reaching obsolescence. What happened to them? In Vietnam many small gunboats were equipped with aircraft 20mm cannons that required more maintenance. The old Oerlikons, requiring less maintenance, would have served the small craft better and there must have been 10’s of millions of rounds or ammunition stored somewhere at the end of 1945.

  8. 2:40:36 also, according to my friend, who did some amount of ship design in college De urodynamic effects of the funnel or anything are actually pretty major, because not only do they slow the ship down but the amount of force it takes to slow the ship down is now being imparted through that piece. The force it takes to slow down a battleship now imagine that the base of the funnel needs to be strong enough to support that

  9. Although the naval budget circa 1876 is basically nothing the US has a large occupation army in the former CSA states for reconstruction at this time so a land invasion of Canada isn't entirely out of the cards although the US would largely be using leftover Civil War surplus instead of cutting edge hardware.

    If a war didn't break out until 1877 the US demobilizes the reconstruction troops so puny army but 1876 the reconstruction troops could be marched North

  10. An interesting instance of rotating torpedo tubes on a sub is the Swedish Sjölejonet-class which sported a pair of external rotating tubes at its aft. Rather than being a particularly large submarine, the Sjölejonet-class was rather small and I believe the use of rotating external tubes came down to a lack of space in the bow to carry more tubes. Why they weren't fixed to the rear and instead made rotating I'm not sure, maybe they thought they might as well since there would be no issue of pressure hull penetration anyway

  11. Love it when you mention the Bremerton Naval Yard. In WWII, my grandfather and uncle both worked there. Other distant relatives also did their part in the area. I love to go to this city and area, and I have fond memories of seeing WWII ships in mothball, and during the Seattle World Fair in 1963, I got to tour the USS Missouri and this probably was a significant factor in my love of Naval history and appreciation of this and other like channels.

  12. You mention that a royal navy sailing 24 hours late would beat the french navy at a not battle of the nile at sea, but would the royal navy be likely to win this engagement? From what I understand, the battle of the nile went so poorly in large part because the french had very few sailors on board its ships, but had a superior fleet overall

    I was always an avation geek
    Now i am both

  14. 2:33:23 Accurate as dodging those torpedoes may have been for WWII-era ships, I've seen an utterly hilarious case where writers tried to apply that in the modern day, with the tv series The Last Ship. It essentially follows the crew of an Arleigh Burke-class destroyer in a post-apocalyptic world (massive global plague) – moderately entertaining overall, but some of the naval combat scenes were ridiculously dumb. In one case, the destroyer is going up against an Astute-class submarine that <this season's generic bad guys> have obtained. The sub launches torpedoes at the destroyer – that's a modern submarine launching guided Spearfish torpedoes – and the destroyer just combs the tracks like in Greyhound. 🤣🤣

  15. While I do like having these split into multiple parts because each can have a time stamp for each question and not hit the limit I do sometimes miss being able to put a single 6 hour long video on in the background while I paint my Adeptus Mechanicus army. All hail the omnissiah!
