      I recently stumbled across images of the “Anti Mobile Fish Torpedo” from 1871 and models of USS Holland (SS-1) and it surprises me that both appear to have a Kort’s Nozzel despite the Kort’s Nozzel not being invented for another 60 years, is this another “Ictineo II” situation where someone unwittingly invented something decades ahead of it’s time but didn’t realize it?

    One of things we historians forget is it isn’t needed to sink a submarine, just keep it from attacking. So while a submarine is avoiding being destroyed, it’s not launching its torpedos. That success is hard to quantify.

    • @joeelliott2157
      @joeelliott2157 7 месяцев назад +42

      To be a really effective anti-submarine aircraft, said aircraft needed three things. Range, Range and Range. And the best of the best was the B-24, because of it's range. It sank more than a few submarines. But what made it really effective was its ability to force a submarine to submerge. This alone was very effective. Think about it.
      It took months to build a U-boat, years for a crew to train. Once ready for combat, by 1942-1943, a U-boat spent most of its time:
      * being repaired and maintained in port.
      * sailing to the mid-Atlantic to take up its station.
      * sailing back to France to replenish.
      * patrolling in a wolf pack, in a long line, searching for a convoy.
      all so it could
      * receive the report of a convoy.
      * spend many hours on the surface, racing to position to attack.
      * launching an attack.
      In a year, a U-boat might spend 8,680 hours preparing for battle and 80 hours in high speed pursuit and battle. If a single measly B-24, with a crew of under 10, could prevent an 8 hour attack, reducing that U-boat's and the 50 man crew effectiveness by 10% for the whole year. In the most critical hours of the year, a U-boat might have to spend several hours, not racing ahead of an 8 knot convoy at 16 knots, but plod along at 1 to 2 knots, surface hours later and race ahead to end up in the wake of the convoy, missing it. To go down in history as a non event.

    Thanks again for an explosive study of the depth charge. The racks and K guns were very stturdy devices as i found out last year chipping paint and repainting them on the USS Slater during our work week before you visited. They had a very nice presentation on the use and setting of the mechanism and allowed me to set it. Something i had wanted to do since i first saw them as a kid. Impressive as they had to set and fire patterns off while rolling around in the violent waters during maneuvers at 18-19 years old holding on to the key! Add into these the Hedgehogs and you can see how the U-boats had life very rough in the latter half of the war. The congressman telling about how our subs were simply diving below the Japanese depth charges should have been keel hauled under the Iowa.

    Greetings and salutations Drax! Thank you for all your fantastic videos, I am an avid fan of yours. I am also an amateur student of Naval History, especially the WW2 period. I am an Icelander, living in Sweden, and I befriended a Brit whose father served in WW2 on the HMS Ashanti. I started to look into the history of that particular ship, and what a story that turned out to be. One of 4 of the 16 RN Tribals that survived the war. Her story reads more or less as "been there, done that". The Norway campaign, (where my friends father was decorated), later the Arctic Convoys (incl possibly PQ 17), definately with PQ 18, down south to the Pedestal Convoy, back up north to the Arctic and then back south taking part in the Torch landings. Later she operated in the Bay of Biscay alongside some of the Canadian Tribals. If ever there was a ship deserving a video of it`s own I would vote for the HMS Ashanti. Again, thanks again for all your fantastic videos, I especially liked your recent ones about AB cunningham and Johnny Walker. All the best to you and yours, Billi Stefansson.

    You went right past the idea, but ship-gun rifle grenades...? I love that idea lol. It's one of those things that sounds kind of mental...but also like it would work. The big problem would likely be loading the things (I don't see how you'd pull that off with guns high up from the deck). That being said, for deck guns, I can imagine you could have a magazine loading system that could give an alright rate of fire. With rifle grenades, the standard bullet might weigh, say 10g; and the rifle grenade might weigh 600g or more. If we kept that same scaling for ease, but only made the grenade fifty times the weight (to lessen stress on the gun) of a standard 102mm round, that could be a 750kg grenade. And you could make them way lighter, or a bit heavier (proportionately). You'd clearly need a powered system to load them, but I could at least see that being done for the foremost and aftmost main guns of a destroyer or smaller ship.
    There's a world out there where, instead of Hedgehog and Squid, the RN just went for firing 1000kg+ destroyer grenades off the main guns.

    The 'K'gun was the mortar that launched the dept charges fired to either side of the ship dropping the charges. I might be the last person to fire one, this happened in 1967 when out left over WW2 seaplane tender was being decommissioned, we had one left over such item dating back to said war. As the new gunnery officer this job was delegated to me, the engineer wished me luck as the steel deck under the wood decking had never been inspected. We went to 'warp' speed, I pulled the line, it went bang, the charge flew to the side and sunk, a large 'boom' was heard, and an immense splash was noted. We turned and returned to the area and noted a large fish kill. There was no damage to the ship (or me). The Navy did NOT want this thing back.

    @joeelliott2157 7 месяцев назад +1

    Excellent video. I have a few questions.
    It appears to me that a better system than having the guess the depth of a submarine would be to just drop a 'bomb' and if it hit something, explode. Like a 'hedgehog bomb' of World War II which uses a 'strike trigger'. With a 'strike trigger' you won't be able to sink a submarine that you were off by 10 horizontal feet but guessed correctly its depth to within 10 feet. But you could sink a submarine with a bomb that did happen to strike a submarine, even if your guess of its depth was off by 100 or more feet.
    Questions for Drachinfel:
    1. Is it correct that a 'strike trigger' bomb would have been more effective than a 'depth trigger' bomb?
    2. If so, did they (during World War I) realize a 'strike trigger' bomb would be more effective than a 'depth trigger' bomb?
    3. With 1910's technology, did they know how to design a 'strike trigger' bomb that was reliable and safe for the crews?
    Thank you for your time.
