In 1999 while crewing a tour boat on Lake Minnetonka, I saw an elderly passenger with a ballcap that said "USS Enterprise 1942-1946". I asked him where he was when the forward elevator blew off after the ship was hit by a kamikaze at Okinawa. He said he was standing in the aft end of the island, and the explosion shook the whole ship.

wrt the question about gas ejection systems in guns, the incident on Missouri that Drac mentioned produced several changes in USN turret design. At the time, the gunners were supposed to inspect the gun chamber for embers or flames, before ramming the next shot. Missouri was on a gunnery training exercise on April 13, 1904. After firing, the crew began ramming the next shot. When the first two bags were rammed, they immediately ignited. Inspection of the turret after the fire found the rammer still fully extended. Flames shooting out of the breech ignited the two bags still on the hoist, because the hoist was completely unprotected. Burning propellant fell from the hoist car in the turret down the barbette, igniting more charges in the handling room at the bottom of the barbette. Thirty six men died that day. The navy decreed that air injections systems be installed in the guns, and that hoists be completely enclosed in trunks with flash proof shutters.

There was one turret explosion in WW2 and the determination was under powered air pressure clearing the breech

BIG PROBLEM with other nations operating blimps in WW2- after the R101 and Hindenburg tragedies, manned airships with hydrogen was OUT OF THE QUESTION. Meanwhile the only nation with helium was the US and we classified it as a 'strategic material' throughout the war. Meaning that the State Department would likely not have released it even to the UK during wartime. So that means pretty much only the US is going to operate manned airships.

[@moodogco]

Yh I understand what your saying but tbh honest Britain by ww2 was using kites in the navy at that the beginning & radar took over as we was the most advanced nation developing it & if it wasn't for us the U.S. would of struggled & been yrs behind. Also tbh we was the only nation that could supply uranium for the manhatton project so I'm sure we had a lot of leverage etc.

"Whose coat is it?" When I was in US Air Force Basic Training, everyone was issued a rubber stamp, laundry-resistant ink, and a stamp pad (I'm fairly certain I still have it - 40 years later). You stamped all your issued clothing items except for socks. You were given scraps of cloth to mark with the stamp and sturdy safety pins used to attach your socks together with the marked scrap. That was to make sure items from the weekly bulk laundry could be returned to you. I forget if my fabric raincoat was dry-clean only, but we had to stamp those as well - I think on the large square manufacturer's military specification label.

At the time, that was the longest tow every successfully completed.

Hi Drach. Regarding the hull numbers for the US Independence-class carriers. If I remember correctly, those ships were originally ordered as "CV", hence their hulls would be contiguous with the other carriers. The "CVL" designation came later, but the hull numbers weren't changed because, as you stated, the ships were still considered part of the fleet carrier mission. The "light" and "heavy" cruisers were pretty much set to the same mission profile, soi they were given hull numbers in series. The Alaska-class were a new breed of cat, so they got a new hull number series.

Drydocks: There is the iconic photo of USS Iowa in ABSD-2. There were several of these docks built that had ten pontoon sections when fully assembled (around 1000ft). For ocean transport the dock was disassembled the wing walls folded down inward to reduce windage so each pontoon could be easily towed individually. The sections could be arranged in any combination, and today the Vigor yard in Portland OR operates a dock with four sections. It is common to see pontoons from ABSD's now used as ramps for unloading car carriers.

[@MKPunch]

About the questing regarding the numbering of coats, inventory is one reason (usually they're one-size-fits-all) and is also for when they are issued they are numbered to recognize what coat belongs to who. The original tradition for numbering the coats was to identify who was wearing what if they, for one reason or another, went into the water and drowned or died from injury. It was a grim way of identifying during the first and second world wars, but it was done for accountability of personnel more than inventory of coats. Now days, the tradition of numbering coats is still a thing, only now the numbers are placed INSIDE the coats and that is for inventory use only.

[@Sweety1915-nono]

Using the last 3 digits of one's service number or similar? Typical in the UK to use last 3 to identify an individual (e.g. smith 849 Vs smith 237

[@MKPunch]

@@Sweety1915-nono For the US, since it is about inventory, it comes down to the number of personnel attached to a unit. The number issued to an individual is generally random, but is recorded upon being issued. If a unit has let's say 2000 personnel attached, then the numbers would start at 0001-2000. Of course, there are replacements in storage for damage or lost items and that became the case, the replacement would take on the number of the item it replaces. Prior to the 1920s, floatation devices weren't required for sailors onboard ship, so numbering jackets was crucial for identification, especially if a body was in the water for more than a few days (decay sets in quickly in salt water), which was one of the reasons why numbering was needed. For sure, if one sailor went overboard and/or was unidentifiable due to injury, it could be deduced that the one person not counted in muster was the the identified sailor. However, if there were multiple sailors involved, their crews would want every avenue of identification they could available to them. Sorry for the rambling. I can get carried away sometimes. 🙃

[@shaun3423]

Regarding the coats at 1:14:23, foul weather gear is not a uniform item owned by individual sailors. They are what's known as organizational clothing. Owned and issued by the ship or command, and inventoried as such. So each one has the organization's name and a number spray painted on them. That does mean that multiple people have used a coat over the life of the ship. At least that is how it is in the modern USN, I suspect it was the same in the RN.

Regarding the "super armour". The changes to the armour deck and how the superstructure is protected could be a bigger deal than the main belt. That's a lot of weight removed from on high. Or, a massive amount of protection for a similar weight.

[@elliottjames8020]

Having had the opportunity to sail on various sailing vessels over the years, I'm thinking particularly of a Top-sail Schooner and 6th rate frigate, I'd make the following observations. The Schooler had restrictive views. You constantly had to change side of the ship because the sails were in the way. The Frigate was a pain in full sail to get any kind of view ahead from the quarter deck because the sails were in the way. If you did furl the mainsails, you could actually see ahead from the quarterdeck.

[@Alsadius]

Regarding the one about resonance and vibration, my wife is a noise and vibration engineer for an airplane manufacturer. Even to this day, their usual way of finding out if something will have vibration issues in the real world is to go put it on a shaker table for hours at a time, varying the frequency, direction, etc. of the movement over and over again. No model is good enough to ensure that it's actually safe - you need to physically shake it and see what happens. If that's what you do for a new headphone jack on the in-flight entertainment system, makes sense that it's much worse for whole ships.

[@lancejohnson1406]

The prop guards on GATO/BALAO class subs were usually removed (COs discretion) before going out on a combat patrol. WAHOO removed hers before leaving Mare Island from overhaul. If you look at the guards, they are constructed in a way that they can be tacked onto the hull while the boat was in dockyard hands and removed when heading out.

You know what would actually make a good ship for a "Band of Brotherrs" series? The USS Pensacola. It was never a major key combatant that stole headlines, but the damned ship was *everywhere*. An overgunned and elderly light cruiser forced to pretend to be a heavy cruiser because of the treaty definitions, she was headed into the Phillipenes during Pearl Harbor and was part of that confused mess in Brisbane, escorted the Lexington (TF11) during the early island raids and got some fo the first American AA kills of the war. At Midway when Yorktown was dead in the water, she shot down four (!) torpedo bombers and probably saved the ship (for a little while). She fought in a ton of actions around Guadalcanal, was alongside Hornet when she was sunk, survived the debacle at Savo Island (although taking a Long Lance and losing over a hundred men) and rolled into Tulagi under her own power while still burning brightly. She escaped Tulagi by camouflaging herself as a freakin' *island* (no joke!) and was back in the fight in less than a year. and fought everywhere from Alaskan waters down to the Phillipenes again. She did shore bombardment on too many islands to list (including the big ones like Iwo Jima and Okinawa. She did everything, her scout plane even scored an aerial kill! After surviving absolutely every thing and earning a ridiculous 13 battle stars, she was *nuked* twice in Operation Crossroads in 1946. The ship was a witness to history, and a show that follows her would cover a great deal of the most interesting parts of the Pacific War.

While I know that most modern explosives are fairly stable without their detonators get them initiated, and the hull of an iron, or steel hulled ship makes a fairly decent Faraday cage, the sort of explosive bolt ideas for detachable armor you were mentioning has me imagining an absolutely terrifying/hilarious scenario where a lightning strike might cause a section of armor to pop off.

With reference to your comment about the number of Oberons preserved, did they become available at the moment that interest in preservation was starting. I was delighted to see Ocelot in Chatham as I saw her launched, in fact I believe she was the one that missed the the entrance to Whitewall Creek and got her stern stuck on the mud on the other side of the river. I actually saw Oberon, Ocelot, Onslaught. Objibwe launched, from our boat which was anchored by the Royal Engineers hard. Okenagan I saw from the shed as dad had complimentary tickets to the launch. Chatham claimed to have built a submarine for every year that the Navy had submarines. I also remember seeing a very well-worn submarine come up the river, possibly early '50s. The story that I heard this was Finwhale, which in company Porpoise had been doing under-ice trials during which they put the wind up USS Skate and a Soviet boat Lurking in the same area. They had been fitted with experimental casings made of fibreglass, unfortunately when they came up through the ice the springiness of the Grp carried away the fixings, the casings then floating away.

[@chrismaverick9828]

Regarding the "quick release armor", another major reason it is a bad idea is the effect of several thousands of tons of armor plate falling off to the ship's stability. Even as a counter to the weight of flooding it would remove the stabilizing force that would otherwise be a partial or substantial counter to the free-surface effect of the flooding.

[@jadeekelgor2588]

Insofar as Naval Technology vs Military Tech. I believe you must look at the continued development of (propeller) screw design. Much of this was the off shoot of regular or civillian industrial design to eliminate cavitation. The idea of special lightweight but strong metal to be used in armor would naturally be developed for commercial cargo ship frame construction. Unless or until some inspired folks put it togeather. It is more likely that armor development would come from military technology. Thus a situation on a cruiser that the modern strong, lightweight frame would carry on it heavy old fasioned armor.

I will say that in the sinking of the Titanic, Collapsible A did actually float off the deck loaded as the Titanic’s final plunge began.

Another possibility if a navy developed a 'super armor' as described would be to *say* it's got 4" of armor, but build it with 5", and watch it shrug off anything smaller than battleship guns. So long as you could keep the secret, having your enemies expect to be fighting a ship with 4" of protection but having it have effectively 10" of protection would be a very rude surprise. Alternately, depending on priorities and doctrine, they could leave the armor at 4", weighing the same as 2", and let the weight savings translate to greater speed, though that might be less of an advantage

About improving the metallurgy of armor using face harden steel, I don't think the improvements would necessarily that great from alloying, heat treatment, etc. I think we would be more consistent in the composition and hardening techniques because of better control. This would mean the margin required to account for quality differences is less and thus the plate could theoretically be made thinner. But the problem would be are you maybe gaining a 2 or 3% reduction in thickness or a 10 or 15% reduction. I tend to think 2 or 3% is more accurate.

Early-model B24s were regarded with suspicion by their crews because the Davis wing flexed rather more in-flight that your average crew was used to. Additionally, some early models were inexplicably lost without any chance to radio out an emergency. The latter (if I recall correctly) was eventually traced to a badly designed hydraulic system. Nevertheless, it was nicknamed 'The Whore', because 'it lacks any form of visible support'. Note: It is possible that I have conflated that nickname with the B26, which was also regarded with suspicion because of the tiny (for the time) wing.

My response was along the lines of 'well, if the USN knows what they are facing, what might they have found in the inventory that would get it done'. The Tallboy (Grand Slam, Cloudmaker) were specifically designed to bore through large amounts of ground and create an underground cavity into which structures above would collapse.

But then again, Britain got Barnes Wallis to design a specific type of bomb to destroy a bunch of dams, then specially rebuilt aircraft and trained crews for that very mission. If, by some odd chance, the USN had got wind of the Iwo Jima fortifications while they were being built, I have to wonder if they would have either a) Asked industry or their allies for a solution, or b) Ignored it and thrown a bunch of marines onto the beach. Bear in mind that the USA developed the rocket-boosted 'Disney' bomb around that time, for destroying hardened U-boat shelters. They also developed some very weird and wonderful weapons that were showing promise in 1945 (pigeon-guided anti-ship weapons and bat-borne incendiary devices for Japan).

[@fidjeenjanrjsnsfh]

Regarding detachable armor, were there any attempts to design ships fitted-for-but-not-with thicker armor to cheat the WNT, like the Countys and their superstructure, or the Mogamis with their guns? If not, why not?

[@WALTERBROADDUS]

Maybe this is just a generational thing? But what is the obsession with Cheating? There seems to be huge portion of the audience who just want to spend time trying to cheat, find loopholes or do something other than actually doing what you are supposed to do?

A laneen is supported from a spar. A jib is simply raised on sheets.

Re: modern tech battleship armour. Would equivalent or significantly better protection come from composite armour?

[@jbepsilon]

Was wondering the same. Like Chobham armor or whatever is used on modern tanks. Might be very expensive though. Also, I guess in the modern era we wouldn't use WWII style AP projectiles. Maybe something like the BROACH warhead used on the Storm Shadow missile, with a shaped charge designed to blow a hole in the armor so the rest of the projectile with the secondary HE warhead can explode inside?

[@gerardlabelle9626]

I am just musing. Useful question: what is the effect of 450kg high explosives on the *unarmored* parts of a ship? (That’s the payload’s of a Tomahawk cruise missile.) An Iowa 16” HE shell contains “only” 70kg HE, by comparison. So a Tomahawk is equivalent to 6+ 16” shells. That could cause significant damage, even if the citadel is intact, enough to put a battleship out of action for many months. The Soviet Granit missile had a 750 kg payload. I don’t think that even needs to penetrate the armor, it would just blow it thru the hull as a projectile 😢. I think that post WW2, firepower (including air power) simply overwhelms protection.

[@whodat7523]

@Drachinifel At 1 hr 5 min, your comments Drach on seaworthiness of floating drydocks sparked a thought- awareness, knowledge and understanding of rogue waves and ship design features to protect against rogue wave encounters didn't arise until after WW2. In hindsight, in reviewing primary and auxiliary warship losses since the emergence of iron hulls, are any now known to be lost to rogue waves either because the hull design was poor or because the ship was unprepared (poorly loaded or overloaded) to encounter and survive a rogue wave? Just how much awareness of unusually huge waves was there given centuries of sea travel in the age of sail, and what if anything was do e with ship design to make ships survivable against what must have seemed like a thing of folklore or legend in those times?

[@KPen3750]

Honestly, focusing on a cruiser like Boise or Helena could be fun. Boise because she was part of ABDA and of guadalcanal fame. Helena because her active career was very active until when she got sunk

[@babboon5764]

Bit of a supplement to the Lucitania sinking in May 1915. The U Boat captain was Walther Schweiger (which Ironically means 'Silent' in English). Much argument ensued about the legitimacy of that but Luscitania was carrying 170+ tons of munitions . He had a bad rep for 'shoot first ask questions later'. This was deserved. 2 months earlier he torpedoed a Hospital ship which would have sunk had the crew not grounded her. He sadly perished in Sept 1917, probably a result of running into a mine.

[@f12mnb]

Ships refueling at sea became a regular action during WWII. Was re-coaling at sea ever standardized or was it just too much of a hassle.

[@WALTERBROADDUS]

You had to put into a harbor to do recoaling. There is no practical way to transfer coal underway.

[@kevinobrien3930]

YES! Coaling was a major problem. When I say coaling I am referring to coaling at a naval base. The Brits (as well as other major powers) were forced to do some MAJOR international negotiation as well as purchasing land from other countries, so as to have a coaling base located within normal "safe" steaming distances, that their ships would be able to travel to w/o them worrying if they were going to run out of fuel. I think 12 Knots was the average war ships cruising speed, as they traveled from nation to nation (gun boat diplomacy). Yet, they had to buy the land, build the base and coal storage facilities, as well as the inlets, harbors, ports and such. They then need to be able to transport the coal from the warehouses (outer harbor vs. inner harbor was sometime done). After bring the oldest coal from the farthest location (something to do w/ keeping it in good use). They then had the actual sailors who's main job was only to deal w/ coal, used wheelbarrow's to carry the coal from the large dump, to 1 of like 50 coal shoots. They were just pipes that lead down into the furnace rooms. Coaling took anywhere from 18-30 hours to reach full capacity (I am NOT positive on the numbers, yet I know it's at least a half a day, b/c a UK combat unit was topping off the coal bins, b/c they had been chasing an enemy, and the captain was worried he would run out it they found the enemy. So, after 12 or hours of coaling, they saw smoke over the horizon, and the captain had his men keep coaling while he had the boilers sparked up, so as to bring them up to temp (that also took 8-10 or more hours, b/c you have bring a LOT of cold water up to furnace temp and pressure (anywheres from 500-1100 degree F, and get the water to pressures levels of similarly crazy levels. The higher and hotter the more speed. But the UK had "beaucoup coal stations all over the world. Side Note: Sorry for my off the wall rambling, to answer your actual question, I believe that they did try doing coaling at sea, w/ some of the first coaling practice was added by the fact that they had put the coal in 50 or 100 bag, to make it easier and faster to coal the ships. This had a significant impact on the speed at which the ships could be coaled, as the sailors didn't have to worry about loose coal falling of the wheelbarrows, (causing possible hazards if they ran into the chunks of coal on the ships deck). Yet since the coal was bagged, it meant that the lumps were relatively the same size, making it easier and faster to tear the bag open and dump it down the pipe. No shoveling, or sweeping up what feel loose, plus no blockages in the actual pipe b/c the size was nearly the same, unlike when it was all loose coal rocks. This also had a positive affect on the lungs of the men, as there was MUCH less coal dust floating around, since it was bagged. BUT, THEy DID NOT do it at sea, like what we do now. They still had to find a sheltered area. (coral reef, atoll, natural harbor, or anyplace that would protect the ships from the enviroment as well as possible enemies. They found a shallow area, drop anchor, and begin the transfer. Or at least that what I remembered from my studies.....3 decades ago....now I feel as old as a coal power ship....hehheh at least I don't feel as old as a sailing ship...EHEHHE take it light --KB

[@f12mnb]

@@kevinobrien3930 Thank you for the detailed reply - so besides having more energy per unit volume, switching to oil meant other improvements in efficiency. Greater range of action (refueling at sea become practical), quicker response time, and ? fewer people needed to do the task (guys connecting the fuel hose versus a lot of guys with wheelbarrows hefting loose coal and bags.)

[@notshapedforsportivetricks2912]

I believe that it was occasionally done during the Great War; for example when a german hilfskreuser recoaled from a prize or from a support vessel. You're correct though, it was time-consuming and involved a lot of faffing about.

Question. I’ve heard that the night Titanic sank there was an optical illusion that prevented the lookouts from seeing the iceberg. Are there any accounts from the age of sail or steam of that same optical illusion affecting a battle? I imagine two ships seeing nothing but darkness and then seeing an enemy point blank range.

[@beaker126]

Since you mentioned it, while not a naval subject, would you consider doing perhaps a fun Friday episode on the Tacoma Narrows Bridge? As a competent engineer who csn also explain things, which is something of a rarity, I'd enjoy hearing your thoughts.

[@philiphumphrey1548]

On Hood and Prince of Wales vs Bismarck, the British do have one big advantage. They can afford their ships to be battle damaged. The Germans, being a long way from the nearest friendly ports, the way to them patrolled by more British ships and aircraft, can't. The damage Bismarck had sustained before the fatal hit on Hood was already critical. She was going to be lucky to get either to Norway or to St Nazaire. Any more damage to Bismarck would have most likely been fatal even if the Germans did pull some sort of pyrrhic victory out of the battle.

40:30 In addition to Dracs point many AA guns has key way liners that could be removed in fairly short order - for example the famous Flak 18/36 /43 (land service weapon) had various iterations key way liners as a few days or a week of heavy bombing would exceed the return fire life of an 88, so onsite replacement was required, but like everything things didn't run as well in life as on paper, for example Flak 43 in original iteration had the liner joint sitting close to the mouth of the chamber / case interface which cause abnormal wear and sometimes jamming - another case of German best being the enemy of the good. Of course lighter weapons like the air cooled variants of Bofors L/60 could replace barrels readily, in a similar way to LMGs can change barrels without affecting the breach / lock work etc.

[@nvelsen1975]

2:51:20 Making a film series Best way to solve that would be to do with they did in the Admiral / De Ruyter film. They compressed the timeline and sometimes moved commanders around to cover more of the Anglo-Dutch Wars and have the protagonist (De Ruyter) be able to do more. Sure you might end up with something ahistorical like Warspite showing up to the Battle of the Eastern Solomons, but it's better than treating viewers to a couple episodes of only deck-scrubbing. 😉

The obvious choice for a naval Band of Brothers is "Tin Can Titans" the story of DESRON 21. They fought from Guadalcanal to the end of the war. Halsey chose them to be the first ships into Tokyo Bay for the surrender. You could take USS Fletcher as the point of focus.

[@88porpoise]

On a naval Band of Brothers style show, I think your mistake is looking for people. A focus on a ship would be an obvious choice for me and I would ideally look for a ship that was present and involved in various events of differing scales and such. For a ship like HMS Norfolk, you ahve the crew on the ship and coming home to Britain as the drums of war start beating. Then move into her hunting for the Scharnhorst, Gneisenau, etc. Then the story of the Bismarck. Moving on to the Arctic and finally getting to sink its teeth into the Scharnhorst. Closing out with operations off Norway, including rhe return of the Royal family. I am sure there are much better options as well. But I believe a ship focussed series would flow much better than one focussed on individuals. Although I would probably prefer a smaller ship what wws present at lots of events to a capital ship. Your core cast would be a selection of ratings and warrant officers who stayed with the ship for the vast majority of the period.
