[@tech4pros1]

some russian submarines do have windows.. they have a weather enclosed bridge deck inside the conning tower as a bridge for surface running. the space is outside the pressure hull and is flooded when the sub dives.

[@hondacrxrus]

@@robertway5756 not windows but what about screen doors 😂

[@grouchyoldpatriot]

Those small round "windows" found in the watertight doors are known as "Dead lights". Or at least they were when I served in the Navy in the 80's / 90's. Their main purpose was for damage control teams to check for fire or flooding in the next compartment before opening a door.

[@tommyblackwell3760]

I'd imagine one of the biggest reasons portholes were blanked out during the War was to make it easier to maintain light discipline underway. No point in making things any easier for the enemy if you can help it.

[@inq101]

Got a family story to back that up. According to my great grandpa who was in the RN the americans "lost widows privilege as they couldn't be trusted to turn the bloody light out."

[@gunnergoz]

Have you ever done a video of the gunnery optics on the ship - those in the 16" gun turrets, the big rangefinders aloft and in the turrets, and the 5" turrets and their controllers? I realize it might be difficult to video through some of those optics but it would be fascinating for those of us who have not had the opportunity to look. I was fortunate to go aboard a Missouri class in the Philippines in the '80's and later on the Alabama on Mobile Bay, so I saw what some of those optics look like when you peer through them.

[@astro-tek]

Though it's not specifically on the turret optics, I watched an older video yesterday titled, "Inside the 16in gun house". He went over some of the range finding equipment and turret periscopes, which were very interesting!

[@Blue_Maxxx]

How about the funnels. Some questions to start with. Do they do more than just vent smoke? What would happen if they take damage?

[@RuralTowner]

If it's anything like vessels earlier in the Steam Age...damage to the funnels affected how the boiler's breathe. Too many holes could adversely affect (reducing) how hot the fires in the boilers would get thus reducing steam pressure. A rough & probably poor analogy would be blowing (akin to the updraft from the boiler fire) through a cracked straw. It's easy to blow through since air escapes in more places & what comes out the end lacks force. With an intact straw more comes out the other end...more force behind hit...ie the updraft of the fire is more forceful ie it's breathing better. How much it would affect the more advanced systems seen later on...not sure. Saw your Q & figured I'd drop my best guess from what was learned from various sources but certain to get corrected in places.

[@trailrunnah8886]

Ryan did a video on the uptakes for MAY 4, 2021, it was to celebrate Star Wars day, and the video was answering the question "Would what destroyed the Death Star destroy Battleship New Jersey?" He shot the video standing inside the funnel, it was pretty interesting stuff. (the funnels are protected)

[@richhagenchicago]

It is interesting in design on those ships as they were designed to avoid a shell going straight down and they have a piece of armor that is perforated with a bunch of holes in it that is very thick to catch and stop shells and bombs before they could make there way further down.

[@stevecagle2317]

I remember hearing that one thing contributing to the rapid sinking of USS Indianapolis was that the Captain McVey allowed them to be open that night due to the hellish heat so as to increase ventilation. As the ship listed the ports went under increasing the flooding.

[@shawnbauman5463]

That was completely normal for a ship of her type operating in the Pacific.

[@davsim4116]

That was one of the sham charges against McVey brought up By the US Navy to hide the fact that they left a ship unaccounted for. First torp blew her bow off the second torp cut her in half.

[@flyer3000]

Everything was McVay's fault (says Adm. King)

[@AvengerII]

Open portholes were also supposed to be a reason the Titanic's sister ship, Britannic sank quickly. That ship operated in the Mediterranean which was much hotter than the North Atlantic if she had ever operated as a passenger line. Instead, she was used as hospital ship for roughly a year. The portholes were left open to release the heat buildup in the lower levels. Unfortunately, at the same time she hit an anchored mine, she was in the middle of a crew shift change in the boiler area so not all the water tight doors were secured, either, if I remember correctly. The mystery of the water tight doors is something they've tried to resolve over the years.

[@robertn2]

If my father was still alive, he be amazed with your knowledge of ships. My father used joke about enlisting in Navy with their recruiting logo "Join the Navy, see the World" through a port hole"

FWIW I joined the Navy when this was the slogan and in 6 years I saw and visited 9 different countries across the Pacific.

[@Plasmacore_V]

The Navy - "You know how to mop, right?"

[@dbfbobt]

I suspect the improvements in electrical generation and ventilation had a great deal to do with the demise of hull portholes over time. The primary business of sailors for the past few thousand years is keeping people in and water out.

[@MrManny34537]

This is one of my favorites, because I see it a lot when I’m in Philly

[@tedmiles2110]

I used to live aboard the US CG Lightship #87-Ambrose at the South Street Seaport; her engine was changed from steam to Diesel in 1933. Her engine room bulkheads show evidence of enlarging the port holes up to 24-inches; we think it was because they could be used as escape hatches from the space. Most of the rest of the port lights were eight inches around the ship. TM retired but still interested.

[@northerncaptain855]

Early in my career as an American Merchant Marine Officer I worked on several WW2 built T2 tankers that had oversized portholes for Bridge windows. Standard sized portholes were used in the accommodations.

[@tonytrotta9322]

U.S. Navy ships like heavy cruiser USS Louisville CA 28 which my dad served on in WW2 their portholes welded shut in hulls for safety to make sure lights could not be seen. Also, smoking - the smoking lamp is lit! Take care! Also, USS Louisville CA 28 in WW2 in the Pacific had an Open Bridge with canvas top.

[@CAPNMAC82]

I recently learned that the Royal Navy would put external balconies on the stern of flagships as part of the Admiral's quarters. How they convinced an Admiral to quarter abaft the rudder post is beyond me.

[@crgkevin6542]

The Royal Navy seems like a very tradition -driven service, so it's probably because in the age of sail the officers were quartered aft, and they just ran with that.

[@B52Stratofortress1]

All officers had access to the stern balcony and it was on all ships of the class not just the flagship. Not sure of its purpose besides a place for the officers to go and hang out, might have been a prestige thing. All British battleships build after and including Hood no longer had it.

[@SeanBZA]

In sailing ships the aft got the fresh sea breeze, so the officers would be there, to get fresh air, with no smell from the ship, and this continued a way into powered ships by tradition.

[@CAPNMAC82]

Mind, the catwalks were on ships near-contemporary to New Jersey, so nothing quaint nor aged. The catwalks were hung over the stern, lower than the main deck, and near to aircraft catapults. This is not the sort of neighborhood where one finds Admirals; their Staff, perhaps, but not the Flag himself.

[@awjustus22]

Obscure feature question: how is time kept on the ship while underway? Does it change as the ship passes through different time zones?

[@tokul76]

Logical answer is that you stick to one time zone cause your schedule depends on time. In good olde times your longitude is calculated based on your clock. You don't change The Clock just cause ship moves thousand miles to the west.

[@MrGrunt01]

You use 2 times, local and Zulu. Zulu is tied to Greenwich Mean Time and doesn't change, local changes as you transit either plus of minus Zulu. So local time could be +8 Zulu or -2 Zulu for example this makes it easier for daily operations while the Zulu time makes it easier to coordinate orders around the world. In WW2 they used very accurate chronometers to keep time, now its satellite based.

[@ionstorm66]

@@MrGrunt01 All navy ships still carry a pair of mechanical chronometers just like they did in WW2. Iowa's kept them in the navigation room in the conning tower. There is also an electrical clock in main engineering that is repeated around the ship.

[@richhagenchicago]

Zulu time.

[@Fa5Squad]

You would go by your native time zone

[@NomadShadow1]

Hmmm, when looking at photographs of older battleships I often wondered what all the little black dots were on the hull because they couldn’t *possibly* be portholes because why would you go to the trouble of having an armored ship just to go and compromise said armor by cutting little holes in it everywhere. 🤯

[@raitchison]

6:43 When I lead tours (which I really only did when training new volunteers) I always pointed out the rounded bull nose on the portholes for the signal shack. That is there because during WWII when a lot of battle orders were relayed to other ships via signal flags the signalmen could retreat inside the (lightly) armored signal shack and run the lines for the signal flags through those holes to send messages for the admiral. The rounded bull nose was to ensure that the lines and flags would not get snagged when the signalmen were raising or lowering the signal flags.

[@31dknight]

Great video from the battleship.

[@Srinathji_Das]

Awesome videos and beautiful museum! 👍

[@markchip1]

Aside from any structural compromise from having hull-side portholes, particularly in the accommodation or low-traffic sections of a ship, I would imagine the strongest reason for deleting them would be to avoid light sources at night potentially making the vessel easier to spot by the enemy. Especially as it is very difficult to see any such flaws from either the deck or superstructure. It is a LOT easier to notice an unshielded or uncovered porthole in the higher decks or where crew will be working or passing frequently.

[@lucash.99]

[@asn413]

The Emperess Of Ireland's sinking was partially due to open portholes.

[@lewisdoherty7621]

The BRITANNIC'S sinking also was partially due to open portholes and the stoking crew jamming the watertight doors open for their convenience.

[@SeanBZA]

Those viewports in the watertight doors would be laminated glass, multiple layers of glass and polycarbonate, probably with the top layers being made from tempered glass, all laminatecx to make a thick sheet, which was then ground down to the right diameter for the opening. Commonly was used for armored windows in banks and other armored applications, where you need a viewport that is resistant to fire, bullets and heavy impact, and which will, for at least a while, resist a raging fire on the other side. You cut it normally using wet grinding and abrasive media, so for the round ones they would have taken the sheet, and used a copper core drill, and either corundum powder or diamond powder, to slowly wear through the outer diameter and leave a smooth finish on the edge, so it does not crack. The sheets of glass are made from alternating layers of float glass and polycarbonate, cleaned and heated under pressure in a mould to get them to fuse together. Just like your car windscreen is.

[@IIGrayfoxII]

2:26 It is said that port holes that were opened sped up the sinking of the HMHS Britannic. While nothing was shot through the port holes. The Britannic at the time was a hospital and she struck a sea-mine, The nurses opened the port holes to ventilate the rooms, despite being told not to. The Britannic was a sister ship to the Titanic, but she sunk in 30minutes or so, compared to Titanic 2hours. The opened port holes did not cause such a decrease in time alone, but the blast warping the hull of the ship preventing the water tight bulkhead doors from closing.

[@lloydknighten5071]

Ryan, I don't remember the book title that had this information. But I recall reading somewhere that the US navy blanked out all hull mounted portholes after Pearl Harbor. That source claimed the open portholes on CALIFORNIA, WEST VIRGINIA, NEVADA, and OKLAHOMA lead to their flooding after being torpedoed.

[@oscarfloyd2678]

My Theory as to why the port holes of the ship were covered up during war time, was to prevent excess light from giving away the ship position during the night.

[@nzcyclone]

I guess the other issue of portholes and why not used is light....It could potentially be a source of light and could give away the ships position at nighttime. I dont know if that is a reason but it would make sense. Moreso is crew areas. Another great video Ryan. Thank you :) Keep safe and well everyone :)

I think Royal Oak was probably one of the reasons a lot of portholes were blanked over.

Navy Ships need to run dark in combat situations. Having a place where light can escape might give away the position of the ship. Red lamps were in passageways near exits to weather decks to maintain night vision for those that need to go out on deck. I always wondered about the phosphorescent wake that the ship left behind at night.

[@lewisdoherty7621]

I wonder how well they show up in the infrared. There has to be a temperature difference between the water and ship, and if a nuclear reactor isn't used there are places where combustion gases must escape. A heat targeting missile would head down a ship's smokestack.

As I remember, the glass part was called a "Portlight", the actual hole with the added closure fittings was the "porthole"

[@comradevlad7459]

I think the Navy's decision to limit through-hulls and portholes was more than likely a maintenance preference. Keeps things simple, and limits places external leaks could come from (not due to combat obviously). My family uses the same logic for through-hulls on our sailing yacht. Less things that could break and gives you peace of mind that you won't lose the vessel to accidental flooding due to a through-hull busting.

In a “modern” 80-90’s task force would New Jersey work with a sub? -how would they communicate?

[@michaelsommers2356]

Even routine peacetime operations of submarines are TOP SECRET, so anybody who knows can't tell you.

[@moo4boy]

if that would happen, my guess is that there either would be orders given to both the sub and the New Jersey prior to sailing or that one of the escorts would coordinate with both the sub and the New Jersey.

[@JM-nt5fm]

Multiple ways to communicate to submarines. Surface fleet use active sonar, so they can communicate via active sonar to the submarine. They can also communicate two ways via satellite buoy. VLF also works as communication to the submarine one way from surface fleet to submarine. That is very low baud rate. Submarine can communicate to the surface fleet via active sonar if subsurface position has been compromised. They also can communicate via satellite link at periscope depth as well as direct lite signals. The craftiest way to communicate is via LPI radio link from another buoy or auv. Lots of ways to remain in contact. One way coded communication to the sub is very easy. Two way is harder to keep discrete. But both are very doable with most opponents. Requires a very, very sophisticated opponent to hamper two way and single direction to the sub is really nearly impossible to hamper. All matters how sophisticated the opponent is. Remember submarines are denial, surface fleet is control, aircraft carriers and missile ships are about power projection. Denial is probably the easiest to achieve of all of those.

[@ionstorm66]

With a sonar if its under water, radio if its at or near the surface or old fashion light signals if its on the surface.

[@darylmorning]

in 1945 the US Navy developed the underwater telephone, also known as UQC, AN/WQC-2, or Gertrude. It's similar to using "two-way" radio but with sound. Now, you can even send digital signals like dial up internet used to be. The ocean is a place where few advances are made.

Blanking portholes isn't just about receiving damage, its equally about night watches and not wanting to disrupt sleep cycles of those who'd be heading to bed shortly after sunrise ect. Military has far more people running 24/7, and if your an engineer working in the hull between 10pm and 6am, you don't want to spend the last 2-3hrs of your shift with morning sun streaming in, and you REALLY don't want light entering bedroom spaces when your asleep during the day.

[@ponchoremerize5508]

The lack of Port-Holes is a survivability issue in that any open space can let in water. Also with the advent of modern engineering and ventilation you don't need to take the extra steps and cost to the vessel.

[@alexandervasquez9324]

Probably the reduced portholes and sealed the already existing ones so that the ship wouldn't sink so fast. A porthole would has a decent size so if the ship is already sinking and the portholes are open or broken water would rush in from the portholes or the would let air out reducing the air pressure allowing the water to more easily enter, it might not make the ship sink incredibly faster, but you know that when the time to evacuate a sinking ship comes every second counts.

[@danmathers141]

Can you do re-enactments that show how the various stations worked with active duty sailors like the bridge and various steering stations?

[@vbscript2]

I would think that one of the main reasons for blanking out the port holes during the war was so that the ship could run dark at night if needed without actually having to turn off all of the lights in the rooms that had portholes. Especially since the Japanese ability to spot targets at night with radar was not so great.

Most likely the lack of portholes or covering them up was more about light discipline. I could also see removing them as they could be landmarking the ships stricture if they are being targeted.

[@MacMcCardle]

Might be a bit odd but is there anything quirky with the steering gear on an Iowa? The two ships I've worked on hard fairly standard for their time equipment but I guess it is kind of interesting in its own right - One had a set of rods that ran the entire 54m length of the deck from the fwd wheelhouse steering gear. Emergency steering was via a few hefty men and a set of tiller like irons that keyed into the top of the rudder posts. I can't imagine that would have been fun work on a 980gwt twin screw. It was allegedly goofy to maneuver under steam, let along via independent and manual steering. The other was far more modern. Still chain driven steering but the steering gear engines were remote to the wheelhouse, located on the mezzanine of the main engine room. There was a main and auxiliary steering gear engine. In the event of failure of the control from the bridge or from the main gear engine you'd use the auxiliary via manual steam valves. A large wheel with very minimal visibility through the aft ventilator was the specified fully manual failover. Engage the dogs and wind like mad.. again, doubt it would have been a merry time crouched on the mezzanine in the heat of the engine room spinning a wheel, facing aft with only yelled directions and a heaving sea for company.

[@Mark-lv1ub]

Ryan, I request your summary of the U.S.S. Bon Homme Richard fire. There must be reports out by now. It seems that the Russian cruiser Moskva suffered the same type of damage...that is a fire that burned thru the entire length of the ship. Look at the few videos of the ship damage and observe the portholes spaced at regular intervals, have black smoke stains coming from them. This suggests a fire along the entire length, probable starting under the bridge. It is likely that the fire set off the forward gun magazine, or the midships missile magazine, (not the huge P-1000 Vulkan missiles). The resultant explosion ruptured the hull and led to flooding. Perhaps even, most of the crew was dead at this time, and could not save the ship. Thanks MCI, DS2, 1980-1986, USS Reeves CG-24, USS Carl Vinson, CVN-70.

Oh idk... I like the window idea... Honestly would like more facts about the ships windows... But... Also. I'd like you to talk about walls.. and roofs. Or ceilings... How thick are the walls at certain places. Or the engine room. And info about that

Now that you’ve covered lights, doors, floor coverings and now portholes can you cover the ships ceilings?!

[@johnscott6083]

Now you're thinking with Port Holes!

[@Quasarnova1]

Interesting to note that the Richelieu had portholes across its whole length despite having an internal belt. But it looks like that is because the Richelieu's bulkhead is external above the belt, making the portholes much more practical in her case.

Iowa class also have "portlights". The only difference between them and portholes is portlights have fixed glass and cannot be opened. I may be wrong but I think the round windows at the wardroom behind turret two are fixed glass.

It's too bad the designers at De Havilland didn't know about the round windows thing before the Comet flew.

Port Holes lost their importance as forced draft and oil firing came to be a thing. Lots of air was screaming through the boiler compartment and no-one was having to shovel coal so temperatures weren't so high. Along with forced ventilation (Plus air conditioning if equipped) . Which is why all the below deck ventilation draft funnels disappeared. Port holes were a flooding risk during heavy seas (much like casemates) and required the crew to be ready to close them if the ship was suddenly attacked by say a submarine during condition X-ray. And along with that they could never be opened during the war as even if the glass was still closed and secure light would stream through them at night which again invited attack by submarine (If one was in the right place). Lastly installing portholes took a decent amount of time and labor by the welders to cut them out and weld in or to rivet in. And eliminating them was just win-win-win. Less cost, less time, less things to worry about especially as below deck ventilation on newer ships wasn't such an issue.

Massive air conditioning closed up the ships, too.

I lol'd pretty good at the submarine comment!

You asked for an obscure feature on a ship to make a video about... How about explaining the strainers on fire mains. I can't remember its name, but there's one at the very beginning of your November 10th, 2020 video named "Fighting Fires on a Battleship". It's the thing that's between the red valve and the hose. Enjoy your videos, thanks. Jack
