Listening to Drach crack up talking about 400-500 foot long engineering space on the 40+ knot battlecruiser has been the Drydock highlight of the year! HAPPY NEW YEAR DRACH!
Regarding restoring a wreck: I wonder how Ryan would react upon being told: “Congratulations, you are now curator of the salvaged USS Pennsylvania, BB38, which is now occupying the Philadelphia Naval Shipyard dry dock. Good luck!” If preserving a ship that has been floating for 80 years is a challenge, what would preserving a 110-year-old ship that’s been submerged for 75 years be like? This is assuming that Pennsylvania can be found, is substantially intact, and doesn’t still glow in the dark. It would be nice to have a standard on display, though. I can’t help but think it would just be far cheaper and easier to build a replica if we are already spending billions. At which point, let’s please just invest in the existing Philly/Camden fleet by getting BB62 and Olympia into drydock and give SS United States the refit she deserves and let sleeping sunken battleships lie.
Pennsylvania wasn't that heavily damaged by Crossroads. The primary difficulty with making her museum ready is that she had pre-existing battle damage that wasn't worth repairing to make her battle ready after the end of World War II. That alone, even without considering any remaining radiation, should make her unsuitable for use as a museum ship even were she somehow salvaged.
Thanks for all your hard work in providing these wonderful informative videos. Maybe we need a T-shirt captioned "I survived a Patreon Dry Dock" That Cuckoo attack would be even more devastating when you consider that ,unlike most other navy's, German sailors did not live on their ships but when in harbor left them and lived ashore. By the time the crews got back to their ships, IF they felt like it, the progressive flooding might be uncontrollable.

The 40-kt battlecruiser is probably a little more feasible than you’ve assumed. The SHP/ton required to reach a given speed goes down as the ship gets larger, because of the square-cube law. Essentially, fluid friction is a function of the surface area (proportional to length squared) and displacement is a function of the volume (proportional to length cubed). And a ship 1200’ long would probably be better at a slightly wider beam than you assumed, more like 120’.
The SS United States wasn’t a warship (although she was designed to be able to be converted into a very fast troopship) but she wasn’t too far off from the specs for this mythological battlecruiser. The United States was history’s fastest ocean liner. She was just shy of 1000’ feet long (990’) w/ a 101’ 6” beam & a max displacement of about 47k tons. She reached 38.32 knots on trials in 1951 & could cross the Atlantic with an average speed of about 35 knots. Supposedly they could push her to speeds in excess of 40 knots for short bursts but this was never verified. Her power plant generated about 280k shp. That’s roughly equivalent to the output of a nuclear-power Nimitz class CVN. This is without armor or weapons of any kind, of course, and well short of Drach’s 46 knot battlecruiser, but still pretty fast. The USS New Jersey, btw, holds the record for highest recorded trial speed by a battleship. She managed 35.2 knots on trials when she was recommissioned for Vietnam in 1968.
in one of the books i got on clipper ships, it is said that some ships captains used to hang ..oil bags.. at the bow this was said to calm the waters around the hull, also add a slippery layer to hull, thus reducing drag and increase the speed there is also a bit of reading in the other book i got, full of obscure info book title, The Use of Oil to Lessen the Dangerous Effect of Heavy Seas
There’s two limits to speed, the second limit is propellers. Most of the large fast ships have been limited because they can’t apply 100% power to the water. You would need double the propellers since making them bigger has diminishing returns.

1:34:19 For reference, Dan Sickles moving his Corps ahead into a indefensible position isn't true, he moved his Corps onto an immensely defensible position, the infamous Devil's Den. A position so awful to attack that Longstreet dragged his feet having to conduct that assault, which perhaps saved the day for the Union. Sickles also moved his forces onto the Peach Orchard which flanked the Confederate attack and caused immense damage to Anderson's attack. The problem however is that Sickles moved his Corps forward without orders and left gaps in the line that had to be filled in at the very last second with reserves. It was a good position to hold but it needed to have been coordinated with Meade, the lack of coordination resulted in chaos in trying to rebuild the line.
Thanks for answering my question! With regards to the vision slits, the French tried to solve a similar problem on their Char 2C super heavy tanks by using stroboscopic cupola's, where slits were placed on an outer cupola that rotated at a certain speed, while the commander looked through vision blocks in the inner cupola and due to an optical illusion could see out of the cupola while theoretically remaining protected. That said it couldn't be done for the whole conning tower due to the scale though maybe a small viewing area could work on this principle, though I can't see it being too popular.
00:44:43 In 1973 leaving Pearl Harbor we rendered honors to the Arizona, and passing on around the north side of Ford Island (before the bridge to the island) also rendered honors to the Utah. These are both considered military grave sites.
That would be the Amerigo Vespucci of the Italian Marina Militare. She had a famous interaction with two US Carriers, being called "the most beautiful ship in the world". Thought perhaps you knew that and were specifically referencing that.
Regarding British turret naming, HMS Tiger's rear superfiring turret was named Q turret, despite not being amidships. All her machinery and funnels were ahead of the turret and the turret thus had the same complete firing arc to the rear that the rearmost turret had. But because the turret was a bit further away from the rearmost turret than usual and because the Lion's all had a Q turret, Tiger also had a Q turret, despite it not making any real sense.
Very happy to hear praises for Godzilla Minus One, it really is a phenomenal film! Looking forward to hearing more about it (and its ships) in the future. :)
The discussion of the 40-knot capital ship reminds me of when I SpringSharped out a 50-knot aircraft carrier; even with no belt armor (...albeit a 3.5-inch-thick armored deck and a 5-inch torpedo bulkhead over the vitals) and no guns larger than a 5"/54 (albeit with 52 of those), it ended up 1,750 feet long (over a quarter of a nautical mile) at the waterline and requiring just over two-and-a-third million shaft horsepower, delivered through an array of 32 propeller shafts (to keep the transmitted power from twisting the propellers off their shafts), with its fuel bunkerage at full capacity _alone_ weighing as much as an entire escalator-clause battleship and a full deep-load displacement of just over 275,000 tons. Speed is hard.
The animated warship (you chopped their name by the way) poses a good question so much that I had to look it up myself... Yes, love to see a Wednesday video on that subject
Re: saluting wrecks I'm not sure of the specifics, but I believe that around the anniversary of the Edmund Fitzgerald, it is common for a ship to issue a master salute when entering Duluth.
A, B, P, Q, X, Y, Z (zed). The only two here that could be mistaken for each other over a battle-damaged voice pipe are B and P, so perhaps it makes sense to get rid of P, rather than Q and not bring a potentially confusing C back into the mix.
In regards to homing pigeons as a communication method, they would have major difficulty navigating at sea. Tracking beacons on pigeons has shown fairly conclusively that they use visual navigation as much as any innate homing ability to get back home. If you take them beyond a few miles from land there is nothing to navigate by, and chances are they'd just fly in circles above the ship for a bit, see nothing near by, and land back on the ship as it is the only thing that isn't water in sight.
"Mass cuckoo attack" Thats a heck of a quote :D My kitty is so used to me playing one of your videos to listen to when I lay down that listening to this confused her. Your voice promised snuggles and she got no snuggles (at first).
For a perfect example of "spending too much money for too little in one ship", I nominate the post war refit of _HMS Victorious_ . While the ship did became a more-or-less efective post WWII carrier, it never carried the number of intended planes. But the worse part was that the refit took 8 years, and the budget went from _5 to 30 million pounds_ . In a cash-strapped post WWII RN, this efectivelly killed any large refits to other carriers.
A month ago, Max Miller at the Tasting History UA-cam channel did some dishes from the 1943 Thanksgiving on the USS Iowa, and went into holiday meals during WWII in the US military
The rituals enacted when crossing the equator might well have been simply humorous. In my touring days, we would tell any American crew to lie down on the bus when we were crossing the Scottish border, and for the most part, they'd fall for it.
Re: hypothetical torpedo bomber raid on the German fleet. Don’t forget the German crews slept in barracks ashore. So as there was do crew on board to effect damage control, probably any hit would result in the ship sinking in harbour.
The USCG, which operates the International Ice Patrol, has a ceremony every year on the anniversary of RMS Titanic's sinking to place a wreath into the water above the wreck.
Condensers on trains were experimented with but the saving in feed water was outweighed by the additional maintenance, weight and fragility. Condensing steam tank locomotives were used on the early underground railways to keep tunnels clear of steam and smoke. They operated by putting the exhaust blast in to the side tanks, while operating outside the tunnels they worked in a conventional manner. One of the main reasons for condensing on a ship are to increase the efficiency of a triple expansion engine or turbine. By condensing the steam you create a vacuum at the exhaust which increases efficiency.
In addition to the conservation of boiler grade water a condenser can be used to operate at a vacuum. When you expand steam to a lower pressure you can extract one third more energy by expanding the steam below atmospheric pressure as you can extract expanding from boiler pressure down to atmospheric pressure. This additional energy would be thrown out in the cooling water rather than using it to spin the propeller shaft with out a condenser operating at high vacuum.
Japanese flying boats had a big influence in the early war, both the USN raids and the Solomons Islands campaign, spotting American carrier task forces.
If Diamond Rock sounds familiar - see Lieutenant Hornblower. During WW2, two WREN establishments, HMS Insurmountable and HMS Impregnable, had to be hurriedly renamed.
Or see Dudley Pope's Ramage's Diamond. He also includes a postscript identifying that the rock was captured in 1804 by Commodore Samuel Hood in the 74 gun Centaur.
Imagine raising the "uss" prinz eugen, i don't know if its still eradiated but i know people dive the wreck all the time, its also in fairly good condition
I'm one of those that stands by the fact that on even the Belfast you can't "grind" gears shifting into reverse.since Belfast has a reversing element attached to the LP turbine which is directly connected to the reduction gear. The gear and clutch segment is for engaging and disengaging the cruising turbine which would be a very bad idea to do at speed. On USN systems the cruising turbines remained connected whether in use or not. this required a system to circulate "cooling" steam though the turbine to prevent over heating when not in use. Improved designs post WW2 and greater efficiency of 1200PSI steam found the cruising turbines more trouble than they were worth and so eliminated.
For a last minute attack on Wilhelmshaven, if you know the terms of the armistice, you dont even have to go to the Netherlands. Just get to a field outside the city and you may well get home before internees in the Netherlands. The Armistice required the immediate release of all prisoners in German custody while, at least theoretically, the Dutch could (maybe even should) maintain the internment until the peace treaty is signed.
Combining the questions about passing honours and Diamond Rock, I understand the Royal Navy still regards the rock as a commissioned warship, and RN ships passing it are required to salute it as they would any other RN warship.
On G-1, great movie, I would have went to see it even without seeing the ships in the trailer, but when those ships, namely Yukikaze and Takao showed up in promo material, I was not gonna miss that movie
How were electric motors on those early XX c. ships regulated? In trains you could either have DC generator with bunch of resistors for controling motor current and shunt field regulator, that isn't most energy efficient or AC generator and tranformer that weights a lot more. For ships that's is less of an issue, but if treaty limits were concerned it still might apply.
1:07:38 To get a prospective on the power required to move a large ship at high seeds, I took a look at the SS United States. With a 45400Ton displacement, 940ft WTL, and 101.5 ft beam, it was able to hit 38.32 knots on a 1952 trial run with a plant rated at 240,000 shaft horsepower. Power / speed curves of trials show that at some point hitting 42Knts very likely a myth. Yet enough secrecy surrounds the ships power plant to make it easy wonder what the true horse power was.
1:16:50 I'm now imagining this gigantic battlecruiser steaming around the ocean so fast that it can chase down E-boats, and I'm giggling at the absurdity of that idea as well as all the madness you described.
Also see WW2Tales for a great new YT series that complements this series Ladies and Gentlemen, this is Part 1 of memoirs of a Japanese Destroyer Captain, He was an Imperial Japanese naval commander during the Pacific War and the author of the IJN manual on torpedo attack techniques, notable for his skill in torpedo warfare and night fighting. He was a survivor of more than one hundred sorties against the Allies and was known throughout Japan as the Unsinkable Captain. A hero to his countrymen, Captain exemplified the best in Japanese surface commanders: highly skilled, hard driving, and aggressive. Moreover, he maintained a code of honor worthy of his samurai grandfather. He was as free with praise for American courage and resourcefulness as he was critical of himself and his senior commanders. He was the only IJN destroyer captain at the start of World War 2 to survive the entire war.
Regarding turret naming schemes, the correct answer is clearly just to use Rule the Waves lettering schemes. That's consistent, simple enough, and a lot of naval geeks will already know it.
Drac I ken sort of off topic, but gun ranges to size. Look at the pop guns on Frigates today look like tank guns. Seeing as missiles cost so much can you see a bigger gun coming back. Shells are cheaper and quicker to make. Love your channel, catching up on Drydocks plus watching the new ones. Happy New year and for what you do drink all the rum and beer.
Drachinifel: @ 1:07:38 you were talking boilers and turbines. From my understanding the Iowas and the (WW2) Essexes had 600 psi boilers. However (also from my understanding) U.S. long haul steam locomotives of the 1930's onwards used 750 psi boilers (the "Big Boy" UP 4014) was built with a 750psi superheated boiler!) Any idea why they didn't upgrade to 750psi? Was it the worry of needing large amount of special alloy metals and the lack of these meant they wouldn't have the reliability and the long life needed for naval use? (Or someone hung up the: "Not Invented Here" sign outside of the Bureau of Engineering door?). Or was it trouble upgrading the Steam Turbines?
when it comes to the "refit" question would the raising of the Pearl Harbour Battleships not count? I've always heard that typically they would be scrapped but the U.S. was desperate for ships
re turbo electric drive - The USN went to turbo-electric because of difficulties manufacturing gearing. When satisfactory gearing became available it adopted it. This included re-engining the older battleships, a program that was started but not complete in December 1941.
51:10 the Japanese had the Katori class light cruiser that was a modern (at the time) light cruiser intended for training. They were all sunk by the Americans if I recall.
18:35 I remember reading in Stalking the Red Bear: The True Story of a U.S. Cold War Submarine's Covert Operations Against the Soviet Union by Peter Sasgen the Soviet Navy had a similar ceremony but it consisted of only eating a piece of hardtack and drinking a shot of seawater
When the RN's Vand W class and pre-WW2 Fleet Destroyers were converted into Escort Destroyers, they first lost Y mount to increase depth charge stowage, then A mount to install Hedgehog. Did the old B and X mounts retain their names or did they become A and Y?
Limited field of view (especially on the Y axis) and prone to damage, otherwise a good idea at protecting the crew. I think the main thing is the command staff want a good field of view and there's not really any way to get this whilst keeping them safe.
Drach, It seems simple enough on my end. "IF" the Germans or Japanese happened upon any sort messaging it would be quite obviously the cause of a substantial amount of confusion and/or brain hemorrhaging when attempting to identify or figure out exactly which gun/turret is the one in question. As an observation this would be an excellent way to filter/weed out a few sailors during exams. Only a rare few could memorize them thats for sure. ----------- Enjoy the New Years festivities Mr. and Mrs. Drach, and keep in mind its amature night as well, Please be safe.
@ 1:03:44 Shin'yo boats were planned to have basically a pair of large 30.5cm or larger (12" or larger) solid fuel rocket motors (looked like a Huge Firework Rocket). It was supposed to use them to get to the attack speed of 80 (or so) knots! Thankfully, only a few apparently were used in attempted attacks and they didn't have the rockets on them. They were the surface navy version of the Kaitens.....
So I have a question. An advantage of electric drives is that you divide up your engineering spaces, this makes me wonder, all else being equal if Prince of Whales had been outfitted with a Turbo Electric Drive would she still have sunk or sunk as fast? Unless I'm misunderstanding turbo electric drives have more compartmentalization and critically shorter propeller shafts because of the need for an additional engineering space to manage the motors. Now part of what Sank Prince of Whales was the spinning up of her damage outer port shaft which damaged and let water in along the shaft alleys. Shorter shaft = shorter shaft alley = less damage = Maybe the ship doesn't suffer as critical of damage?
On the subject of hydrophones and torpedoes, the sonar on USS England (DE-635) detected the propeller of an incoming aerial torpedo on sonar while off Okinawa. IIRC while sailing at 12-13 knots or so.
There are also some reports of Scharnhorst, Gneisenau and Tirpitz having used hydrophones to detect torpedoes while at sea that can be found on the internet, and also Drach himself stated in his second live stream Q&A that Bismarck and Tirpitz did have hydrophones (and sonar on tirpitz). And I found several articles talking about operation source (the x craft attack on tirpitz) which claim that during the night tirpitz was on continuous hydrophones watch, but that it was deactivated at around 05:00 in the morning for maintenance on that particular day
Why is there a periscope in the background of the picture of SMS Baden? It would seem like a hazard for a sub to enter the approaches of a port submerged unless it had nefarious intent.
@47:20 - what a great photo, all those (well trained) sailors on the rigging, not a harness or any form of P.P.E. in sight! Do we have to go to war to escape Health and Safety people?
On the subject of " a subordinate commander ignoring orders" and racing off on his own, what about Lieutenant Commander Waldron leading Torpedo 8 off in defiance of his air group commander at Midway?
Regarding España vs Dalton, it says a lot that a very small dreadnought has a fighting chance against the best semi-dreadnought battleship, 3000tm bigger. I guess the problem was their very low displacement to get enough heavy guns. Italy had offered the Spaniards a better 16100tm design with an 8 gun broadside in 2 triple and 1 twin turrets. And a 17000tm variant capable of 21 knots. Still well below the 18750tm of Dalton but well superior on speed and broadside.
Hi Drach, Been enjoying your content for a while now, and got a question (I am not very clued up on naval warfare as a tank expert) but I was wondering I saw a T34 Turret on some naval boats on war thunder, I was wondering if any other ships used tank turrets as a main armourment or even secondary?
1:45:00 By adding lense to broaden the view of a given sized viewport on a conning tower will result in less ability to see detail and likely harm low light vision. Another trade off.
Mentally watching Drach pull his hair out over turret designation, is a great way to go into the new year. Thank you for being you.
the phrase,
"...Beatty launching a mass Cuckoo attack..."

But because the turret was a bit further away from the rearmost turret than usual and because the Lion's all had a Q turret, Tiger also had a Q turret, despite it not making any real sense.
Very happy to hear praises for Godzilla Minus One, it really is a phenomenal film! Looking forward to hearing more about it (and its ships) in the future. :)
The discussion of the 40-knot capital ship reminds me of when I SpringSharped out a 50-knot aircraft carrier; even with no belt armor (...albeit a 3.5-inch-thick armored deck and a 5-inch torpedo bulkhead over the vitals) and no guns larger than a 5"/54 (albeit with 52 of those), it ended up 1,750 feet long (over a quarter of a nautical mile) at the waterline and requiring just over two-and-a-third million shaft horsepower, delivered through an array of 32 propeller shafts (to keep the transmitted power from twisting the propellers off their shafts), with its fuel bunkerage at full capacity _alone_ weighing as much as an entire escalator-clause battleship and a full deep-load displacement of just over 275,000 tons.
Speed is hard.
The animated warship (you chopped their name by the way) poses a good question so much that I had to look it up myself... Yes, love to see a Wednesday video on that subject
We used to always rendered Honors to the Statue of Liberty when entering New York Harbor, and the USS Constitution when entering Boston Harbor....
Re: saluting wrecks
I'm not sure of the specifics, but I believe that around the anniversary of the Edmund Fitzgerald, it is common for a ship to issue a master salute when entering Duluth.
I swear it seems like a whole year has passed since I started watching this episode…
A, B, P, Q, X, Y, Z (zed). The only two here that could be mistaken for each other over a battle-damaged voice pipe are B and P, so perhaps it makes sense to get rid of P, rather than Q and not bring a potentially confusing C back into the mix.
In regards to homing pigeons as a communication method, they would have major difficulty navigating at sea. Tracking beacons on pigeons has shown fairly conclusively that they use visual navigation as much as any innate homing ability to get back home. If you take them beyond a few miles from land there is nothing to navigate by, and chances are they'd just fly in circles above the ship for a bit, see nothing near by, and land back on the ship as it is the only thing that isn't water in sight.
44:43 All Greek navy ships entering Pireus honor Georgios Averoff, now a museum ship.
"Mass cuckoo attack" Thats a heck of a quote :D
My kitty is so used to me playing one of your videos to listen to when I lay down that listening to this confused her. Your voice promised snuggles and she got no snuggles (at first).
For a perfect example of "spending too much money for too little in one ship", I nominate the post war refit of _HMS Victorious_ . While the ship did became a more-or-less efective post WWII carrier, it never carried the number of intended planes. But the worse part was that the refit took 8 years, and the budget went from _5 to 30 million pounds_ . In a cash-strapped post WWII RN, this efectivelly killed any large refits to other carriers.
A month ago, Max Miller at the Tasting History UA-cam channel did some dishes from the 1943 Thanksgiving on the USS Iowa, and went into holiday meals during WWII in the US military
The rituals enacted when crossing the equator might well have been simply humorous. In my touring days, we would tell any American crew to lie down on the bus when we were crossing the Scottish border, and for the most part, they'd fall for it.
Always great stuff! Happy New Year!
Re: hypothetical torpedo bomber raid on the German fleet. Don’t forget the German crews slept in barracks ashore. So as there was do crew on board to effect damage control, probably any hit would result in the ship sinking in harbour.
Regarding passing honours, I believe that the US Navy generally has a ceremony of some sort whenever they pass through Ironbottom Sound.
There is a mention of such on the wikipedia page: en.wikipedia.org/wiki/Ironbottom_Sound
I’d be really happy to see Nagato wreck being restored
Happy New Year Drach, and everyone else as well
The USCG, which operates the International Ice Patrol, has a ceremony every year on the anniversary of RMS Titanic's sinking to place a wreath into the water above the wreck.
That is very good info. Thank you.
Condensers on trains were experimented with but the saving in feed water was outweighed by the additional maintenance, weight and fragility.
Condensing steam tank locomotives were used on the early underground railways to keep tunnels clear of steam and smoke. They operated by putting the exhaust blast in to the side tanks, while operating outside the tunnels they worked in a conventional manner.
One of the main reasons for condensing on a ship are to increase the efficiency of a triple expansion engine or turbine. By condensing the steam you create a vacuum at the exhaust which increases efficiency.
Happy New Year to you and yours, Drach!
Yes we must have a Wed video on the insane German rocket boats!!!!
I like the all forward design, because as long as you are facing the opponent you get 3 large shields in front of your superstructure and engines.
Godzilla - 1 almost acheived the historical accuracy of U-571!!
Yes, yes, and yes . Id love to see the hot rod E-boats !
In addition to the conservation of boiler grade water a condenser can be used to operate at a vacuum. When you expand steam to a lower pressure you can extract one third more energy by expanding the steam below atmospheric pressure as you can extract expanding from boiler pressure down to atmospheric pressure. This additional energy would be thrown out in the cooling water rather than using it to spin the propeller shaft with out a condenser operating at high vacuum.
Japanese flying boats had a big influence in the early war, both the USN raids and the Solomons Islands campaign, spotting American carrier task forces.
If Diamond Rock sounds familiar - see Lieutenant Hornblower. During WW2, two WREN establishments, HMS Insurmountable and HMS Impregnable, had to be hurriedly renamed.
Or see Dudley Pope's Ramage's Diamond. He also includes a postscript identifying that the rock was captured in 1804 by Commodore Samuel Hood in the 74 gun Centaur.
Happy New Year, Drach!
Drach: "How about a video about Nazi Germany going full on Wiley E Coyote on the water?"
YES! YES! YES!
That sound absolutely delightful!
Imagine raising the "uss" prinz eugen, i don't know if its still eradiated but i know people dive the wreck all the time, its also in fairly good condition
I'm one of those that stands by the fact that on even the Belfast you can't "grind" gears shifting into reverse.since Belfast has a reversing element attached to the LP turbine which is directly connected to the reduction gear. The gear and clutch segment is for engaging and disengaging the cruising turbine which would be a very bad idea to do at speed. On USN systems the cruising turbines remained connected whether in use or not. this required a system to circulate "cooling" steam though the turbine to prevent over heating when not in use. Improved designs post WW2 and greater efficiency of 1200PSI steam found the cruising turbines more trouble than they were worth and so eliminated.
For a last minute attack on Wilhelmshaven, if you know the terms of the armistice, you dont even have to go to the Netherlands. Just get to a field outside the city and you may well get home before internees in the Netherlands.
The Armistice required the immediate release of all prisoners in German custody while, at least theoretically, the Dutch could (maybe even should) maintain the internment until the peace treaty is signed.
Combining the questions about passing honours and Diamond Rock, I understand the Royal Navy still regards the rock as a commissioned warship, and RN ships passing it are required to salute it as they would any other RN warship.
Thanks Drach.
As to passing honours, there is the german naval memorial at laboe near Kiel, german ship do always honour it, foreign ships may do it.
On G-1, great movie, I would have went to see it even without seeing the ships in the trailer, but when those ships, namely Yukikaze and Takao showed up in promo material, I was not gonna miss that movie
In terms of a historic ship to raise, would either of the Blucher's be suitable, or maybe Lutzow (WW1)
How were electric motors on those early XX c. ships regulated? In trains you could either have DC generator with bunch of resistors for controling motor current and shunt field regulator, that isn't most energy efficient or AC generator and tranformer that weights a lot more. For ships that's is less of an issue, but if treaty limits were concerned it still might apply.

To get a prospective on the power required to move a large ship at high seeds, I took a look at the SS United States. With a 45400Ton displacement, 940ft WTL, and 101.5 ft beam, it was able to hit 38.32 knots on a 1952 trial run with a plant rated at 240,000 shaft horsepower. Power / speed curves of trials show that at some point hitting 42Knts very likely a myth. Yet enough secrecy surrounds the ships power plant to make it easy wonder what the true horse power was.
1:16:50 I'm now imagining this gigantic battlecruiser steaming around the ocean so fast that it can chase down E-boats, and I'm giggling at the absurdity of that idea as well as all the madness you described.
But if the E-boat takes even a lazy turn one way or another, the battlecruiser will be in another hemisphere before it can turn around!
@@greenseaships part of why the idea is so comical to me. You've basically got a battlecruiser that moves around like a torpedo when going top speed.
Wednesday for the madcap eboat designs would love to see that
Rocket powered E boats? YES PLEASE!!
Also see WW2Tales for a great new YT series that complements this series
Ladies and Gentlemen, this is Part 1 of memoirs of a Japanese Destroyer Captain, He was an Imperial Japanese naval commander during the Pacific War and the author of the IJN manual on torpedo attack techniques, notable for his skill in torpedo warfare and night fighting. He was a survivor of more than one hundred sorties against the Allies and was known throughout Japan as the Unsinkable Captain. A hero to his countrymen, Captain exemplified the best in Japanese surface commanders: highly skilled, hard driving, and aggressive. Moreover, he maintained a code of honor worthy of his samurai grandfather. He was as free with praise for American courage and resourcefulness as he was critical of himself and his senior commanders. He was the only IJN destroyer captain at the start of World War 2 to survive the entire war.
Regarding turret naming schemes, the correct answer is clearly just to use Rule the Waves lettering schemes. That's consistent, simple enough, and a lot of naval geeks will already know it.
Drac I ken sort of off topic, but gun ranges to size. Look at the pop guns on Frigates today look like tank guns. Seeing as missiles cost so much can you see a bigger gun coming back. Shells are cheaper and quicker to make. Love your channel, catching up on Drydocks plus watching the new ones. Happy New year and for what you do drink all the rum and beer.
_A machinery space about 500 feet long_
The Omnissiah just grabbed the lotion.
is here, notification (set to all) received, subscribed, gave you a 👍! 🙂Audio video is good.
Drachinifel: @ 1:07:38 you were talking boilers and turbines. From my understanding the Iowas and the (WW2) Essexes had 600 psi boilers. However (also from my understanding) U.S. long haul steam locomotives of the 1930's onwards used 750 psi boilers (the "Big Boy" UP 4014) was built with a 750psi superheated boiler!)
Any idea why they didn't upgrade to 750psi? Was it the worry of needing large amount of special alloy metals and the lack of these meant they wouldn't have the reliability and the long life needed for naval use? (Or someone hung up the: "Not Invented Here" sign outside of the Bureau of Engineering door?). Or was it trouble upgrading the Steam Turbines?
when it comes to the "refit" question would the raising of the Pearl Harbour Battleships not count? I've always heard that typically they would be scrapped but the U.S. was desperate for ships
re turbo electric drive - The USN went to turbo-electric because of difficulties manufacturing gearing. When satisfactory gearing became available it adopted it. This included re-engining the older battleships, a program that was started but not complete in December 1941.
51:10 the Japanese had the Katori class light cruiser that was a modern (at the time) light cruiser intended for training. They were all sunk by the Americans if I recall.
Katori and Kashii were sunk, Kashima survived the war.
Wednesday special on madcat German designs? Yes please Mr. Drach.
Carrier pigeons aboard transferred a long distance from home - pigeon pie for the wardroom!
18:35 I remember reading in Stalking the Red Bear: The True Story of a U.S. Cold War Submarine's Covert Operations Against the Soviet Union by Peter Sasgen the Soviet Navy had a similar ceremony but it consisted of only eating a piece of hardtack and drinking a shot of seawater
When the RN's Vand W class and pre-WW2 Fleet Destroyers were converted into Escort Destroyers, they first lost Y mount to increase depth charge stowage, then A mount to install Hedgehog. Did the old B and X mounts retain their names or did they become A and Y?
32:20 You can google "Shootout between H6K and a B-17".
@ 1:41:59 Periscopes? (For conning towers in heavily armoured ships)
Limited field of view (especially on the Y axis) and prone to damage, otherwise a good idea at protecting the crew.
I think the main thing is the command staff want a good field of view and there's not really any way to get this whilst keeping them safe.
Drach,
It seems simple enough on my end.
"IF" the Germans or Japanese happened upon any sort messaging it would be quite obviously the cause of a substantial amount of confusion and/or brain hemorrhaging when attempting to identify or figure out exactly which gun/turret is the one in question.
As an observation this would be an excellent way to filter/weed out a few sailors during exams.
Only a rare few could memorize them thats for sure.
-----------
Enjoy the New Years festivities Mr. and Mrs. Drach, and keep in mind its amature night as well, Please be safe.
yes please to a Wednesday video about crazy german boat!
Yes Wednesday video on crazy German E-boats
34:05 Drach, surely “Ze Plan” is also a German plan?
I’ll get my coat…
@ 1:03:44 Shin'yo boats were planned to have basically a pair of large 30.5cm or larger (12" or larger) solid fuel rocket motors (looked like a Huge Firework Rocket). It was supposed to use them to get to the attack speed of 80 (or so) knots!
Thankfully, only a few apparently were used in attempted attacks and they didn't have the rockets on them. They were the surface navy version of the Kaitens.....
So I have a question.
An advantage of electric drives is that you divide up your engineering spaces, this makes me wonder, all else being equal if Prince of Whales had been outfitted with a Turbo Electric Drive would she still have sunk or sunk as fast?
Unless I'm misunderstanding turbo electric drives have more compartmentalization and critically shorter propeller shafts because of the need for an additional engineering space to manage the motors. Now part of what Sank Prince of Whales was the spinning up of her damage outer port shaft which damaged and let water in along the shaft alleys. Shorter shaft = shorter shaft alley = less damage = Maybe the ship doesn't suffer as critical of damage?
On the subject of hydrophones and torpedoes, the sonar on USS England (DE-635) detected the propeller of an incoming aerial torpedo on sonar while off Okinawa. IIRC while sailing at 12-13 knots or so.
There are also some reports of Scharnhorst, Gneisenau and Tirpitz having used hydrophones to detect torpedoes while at sea that can be found on the internet, and also Drach himself stated in his second live stream Q&A that Bismarck and Tirpitz did have hydrophones (and sonar on tirpitz). And I found several articles talking about operation source (the x craft attack on tirpitz) which claim that during the night tirpitz was on continuous hydrophones watch, but that it was deactivated at around 05:00 in the morning for maintenance on that particular day
A 40kt cruiser would make an awesome target, and subs could dispense with targeting gear and carry more torpedoes.
Why is there a periscope in the background of the picture of SMS Baden? It would seem like a hazard for a sub to enter the approaches of a port submerged unless it had nefarious intent.
So, in a race between HMS Incomdrachable and USS Geordrach, who would end up laughing the loudest? :)
@47:20 - what a great photo, all those (well trained) sailors on the rigging, not a harness or any form of P.P.E. in sight! Do we have to go to war to escape Health and Safety people?
On the subject of " a subordinate commander ignoring orders" and racing off on his own, what about Lieutenant Commander Waldron leading Torpedo 8 off in defiance of his air group commander at Midway?
Steam ships also have the availability of sea water to cool in the condensor path vs using air to extract the heat on a rail locomotive.
Regarding España vs Dalton, it says a lot that a very small dreadnought has a fighting chance against the best semi-dreadnought battleship, 3000tm bigger. I guess the problem was their very low displacement to get enough heavy guns. Italy had offered the Spaniards a better 16100tm design with an 8 gun broadside in 2 triple and 1 twin turrets. And a 17000tm variant capable of 21 knots. Still well below the 18750tm of Dalton but well superior on speed and broadside.
Hi Drach, Been enjoying your content for a while now, and got a question (I am not very clued up on naval warfare as a tank expert)
but I was wondering I saw a T34 Turret on some naval boats on war thunder, I was wondering if any other ships used tank turrets as a main armourment or even secondary?
1:45:00 By adding lense to broaden the view of a given sized viewport on a conning tower will result in less ability to see detail and likely harm low light vision. Another trade off.
