The Drydock - Episode 257 (Part 2)

[@Drachinifel]

Pinned post for Q&A :)

[@talksinsentences]

What is that French ship (pre-Dreadnought? armoured cruiser) that seems to be attempting to emulate a diving submarine at roughly the 27-37 minute mark? Was the forward freeboard really that low or had she suffered damage?

[@gokbay3057]

@@talksinsentences Could be Dupuy de Lome but that would require her to be lower in the water than she usually is most of the time. Otherwise there are several battleships that look similar like Charles Martel, Carnot, Jauréguiberry, Masséna or Bouvet (or even the earlier Brennus).

[@gokbay3057]

BTW Drach, I know it is past it now what with the next Drydock already being out but you forgot to pin this comment.

[@zstewart]

You've talked here about automatic fuze setters being centrally controlled, and elsewhere you've talked about sending ranging data from rangefinders to fire control computers and firing solutions from fire control to turrets before, but my question is how was this done? What kind of signals were actually put on the wire to tell a turret e.g. how high to elevate? (As a programmer who's worked a little bit with hardware, I'm assuming the signals are analog, but was it as simple as a variable analog voltage? That seems like it would potentially lack precision and be prone to interference so I wonder if something more complex is going on.)

[@davidvik1451]

01:24:57 In this segment you note the compartment for the "Oil King" musing over what that was? Well, I was an Oil King. The Oil King works out of the "oil shack" and on larger ships may have several people working under them, in my case it was myself and a part time assistant. The Oil King has the job of overseeing refueling, internal transfer of fuel, keeps track of boiler feedwater, maintains proper boiler chemistry along with all the associated records which includes the "Fuel Oil & Water Report" for the Captains daily midnight reports. You also were the guy that kept the ship trimmed and ballasted. I've also seen the title of "Water King" which i believe is only seen on larger ships like carriers and such.

Per the USN high pressure high temperature machinery: part of what allowed the high pressures and temperatures was a detail in the turbine rotor. Parsons turbines could have individual blades swapped on the rotor which was good for maintenance, but it meant that the rotor and blades expanded more in the pressures and temperatures beyond 400 PSI (that and their larger size and diameter meant that the expansion was greater too). The USN Bureau of Engineering under Harold Bowen Sr. developed forged rotors which meant you couldn't replace the blading, but it didn't expand as much with pressures of 400+ PSI, leading to smaller machinery with greater efficiency and power output (double reduction gearing also helped in this as the smaller turbines spun much faster than larger Parsons derived turbines). Bowens book, "Ships Machinery and Mossback" goes into fairly good detail on this. I've been looking into how the USN developed steam plants from 1930-1945 and its quite the journey from something like USS New Orleans to USS Salem and USS Farragut to USS Gearing.

The Oil King is the enlisted man ( small ships) or petty officer (large ships) in charge of the ship's fuel supply. He supervised refueling operations and ran the piping manifolds directing fuel to the various tanks, pumped fuel from one tank to another to correct trim as fuel was burned, sounded the tanks daily and reported the quantities to the ships Engineering Officer and was responsible for maintaining the fuel supply system - tanks, piping, pumps, filters and strainers - to the boilers. The Oil King's store would have the spare and repair parts needed to maintain the system. "He quickly learned on his first assignment aboard the USS Wallace L. Lind (DD-703) that there are no one-trick ponies in the Navy, and according to Dalby, when he wasn’t firefighting, he was going to be “Oil and Water King.” “My job was to run up and down, making sure the tanks all over the ship held the necessary fresh water and oil.” And while the “uninitiated” may not realize the importance of the sea monarch, the “Oil King,” donned in an oil-stained shirt and pants, controlled the ship ballast and all the freshwater. The role is one of the most “mighty important men for you and your ship,” according to the November 1958 issue of “All Hands” naval magazine." www.hullnumber.com/ALL-HANDS/article.php?title=the-oil-king-sea-going-monarch On some ships, at least, there was a Water King, - my uncle Jimmy served as part of his party on an LSD after he was promoted from Fireman First Class to Water Tender Third. The King was in charge of the ship's fresh water supply, - evaporators (always "the Vaps"" to the Black Gang) piping, tanks, filters, strainers, etc - to make up the feed water supply to the boilers and drinking water to the Galley and scuttlebutts. My uncle served as one three watch standers in the Water King's gang, assisted by Firemen striking for Water Tender. Diesel powered ships had a bastardized system to provide the crew with fresh water, but my uncle was glad he never had to deal with one. "In the United States Navy, "watertender" (abbreviated WT) was a petty officer rating which existed from 1884 to 1948. Watertenders held a paygrade equivalent to today's petty officer first class. A chief watertender (CWT) paygrade was established in 1903. In 1921, the lower paygrade was split into watertender first class (WT1 or WT1c) and watertender second class (WT2 or WT2c). Another lower paygrade, watertender third class (WT3 or WT3c), was established in 1943. The watertender and boilermaker ratings were merged into a new "boilerman" rating in 1948, which merged into "machinist's mate" in 1996"

Turret stops. Lockout cams were also used. Allowed for full traverse, but kept you from shooting yourself. Usually. Dad was gunnery officer on USS COLLETT (DD730) , a new build at the time. In November 44, she was attacked by 4 Japanese aircraft. While she had extensive training, and some combat, this was the first extended battle she was in. There was an explosion in the gun tub, and Dad ran to see what happened. There was blood everywhere, and it was immediately obvious to Dad that he had FU'd -- he said he had set all the cutout tabs for the gun to prevent firing into the superstructure, but, in the cooling buckets, there were two hot barrels that had been swapped out due to the extended engagement time. He had never cut cams for them, since they had never been used in anger before. Fortunately, all the blood was from superficial nicks -- no significant injuries to anyone in the crew. But they got two of the aircraft, a third went away smoking, and nobody knew what happend to the fourth. Typical combat.

The uncle of a friend of mine served on USS Missouri on a 40mm quad mount. He said the worst part of that was when the 5 inch guns above their heads fired. He said his helmet was dented from the blast effect overhead. Also he said the only hearing protection he had was to stuff his ears with cotton. Didn't sound like much fun to me but he had fond memories of his time on the ship.

[@nathanokun8801]

As to the 1200 psi propulsion plants made for US light cruisers and later missile-firing ships, the laws of thermodynamics do indeed give better efficiency to higher temperqature differences and the resultand higher pressures used in the engnes. Maintenance was indeed a significant problem. Even a small leak could be EXTREMELY dangerous to the "snipes" maintaining said systems. For example, such steam leaks, if creating a jet shooting from some crack or hole, could be invisible in the air until it had cooled down considerably at some distance from the actual leak point. To find said leaks, a long broom handle was swung around in front of the personnel as they SLOWLY moved toward the leak area and many leaks were found when it was SLICED IN HALF by the jet. (Instead of the snipe, of course.) Dangerous work!!!

[@nathanokun8801]

In the middle of WWII, the US finally decided that using "VT" nose fuzes in AA shells (proximity fuze using tiny short-range radio-like transmitter/detectors in the fuze side to blow it up near a target, greatly reducing any range-error problems) was needed, clearing the previous "secret" label inhibiting their use. It was very quickly found that the base tracers (glow-plugs in the rear of many AA shells to allow night/day tracing of the shell by the gunners to quickly adjust their aim) created a long smoke-like plasma that was electrically conductive. This long trail of near-invisible smoke turned out to really distort and mess up the ability of the VT detector circuits to be set off properly. Thus, VT fuzes could not use such tracers and they actually fired a mix with a few spaced time fuzes when using VT fuzed shells to give back the aiming help to the gunners.

[@nathanokun8801]

US Navy 1200-psi steam plants in guided missile cruisers, and so forth. These were EXTREMELY dangerous if they had steam leaks. The steam was "dry" and invisible for some time until it cooled down considerably. Thus, a leak would in many cases be far away from the visible steam cloud it formed, To find out where the actual leak was, one of the ways used was to get a wooden rod (mop handle, for example) and slowly move forward, swinging the handle back and forth in front of you over the entire area deck to overhead. When the handle was sliced in two, you had found the leak. "Snipes" who worked on such power plants lived in a different world from the rest of the crew!!

[@MyMongo100]

We occasionally get leaks on the MSV steam chests on a supercritical unit. Although the steam is dry and has a couple of hundred degrees of superheat it can usually be seen because any moisture in the air it passes through becomes saturated steam. Agreed though near the leak where it has a higher velocity it can be invisible.

[@davidbrennan660]

If you work with steam you soon respect it and its habit of trying to kill you and destroy what it is in...... it is nasty, mean and sneaky.

[@nathanokun8801]

An interesting thing about the British 9.2" guns used for coast defense in WWII. These guns were repurposed WWI-era British Navy guns for the most part. During the late 1930s a new Mark 12B (long windscreen) APC shell was developed for these guns that weighed the same as the original APC shell of WWI use and even retained the same 3.8% Shellite filler size (instead of the original Lyddite filler). One would think that the new shell, because of the large 8internalk cavity by WWII British standards (2.5% was used in the new battleship APC shells, mostly Shellite with TNT with beeswax for the 16" Mark IB APC, as used in the smaller WWII British cruiser-size anti-armor shells, 6" CPBC and 8" SAPC). However, the 9.2" Mark 12B APC shells were made to the same standards as the larger WWII battleship shells and, amazingly, had the same armor penetration ability as the larger shells did. While British WWII APC was rather soft and bent rather than broke in many cases when hitting thick face-hardened armor, the fact that this 9.2" shells large cavity did not compromise the anti-armor capability of these APC shells in worth noting. It seems that the improve WWII British AOC shell design, while unable to penetrate really thick armor due to the bending on impact, actually was superior to many other designs when hitting more reasonable armor thicknesses up to about caliber thickness. Don't use it against things like YAMATO or the turrets of US WWII battleships, but otherwise these new 9.2" APC shells were quite effective against their expected targets.

Concerning non-firing/non-pointing zones, With the older guided missile launchers, they also acted like guns with the missiles replacing the gun barrels when loaded. Originally, the cut-out stops were remeasured after each overhaul and the values where the launcher would disconnect the firing circuit and force the launcher to elevate so that it was pointing inti the air above the ship when rotated toward the superstructure would be entered into the aiming computer software (after digital computers replaced the gear-driven types). This was tedious, let me tell you! One day I was doing this for the Mark 76 TERRIER AAW Guided Missile System on a warship when a sudden light-bulb went off with a BANG in my head: WE HAVE GUIDED MISSILES THAT AIM AT THE TARGETS! WHAT AM I DOING THIS FOR?!?!?!? I decided that over the arc of the blocked superstructure you instead simply aim the launcher up to 45 degrees and fire there, telling the missile the offset to still aim at the target (a rather small patch needed for such a fixed elevation value). The radars tracking the targets were high on the superstructure and had only a very small blind zone, so normally that was not a problem. I called it "FIRE AROUND THE LAUNCHER BLIND ZONE" and it removed the no-fire cutout logic since the launcher never went "blind". This was later changed by others to "Curve Fire Mode". I submitted it as a run-of-the-mill BENEFICIAL SUGGESTION to increase the launcher bearing aim ability by 50% (toward the other end of the ship from the launcher position). My boss sent it to the Applied Physics Laboratory of John Hopkins University (TERRIER Design Agent) for testing to see if there were any targets this interfered with. They found it worked against ANYTHING!! Indeed, shortly thereafter, they decided to use 45 degrees ALWAYS, no matter what bearing the target was, making the patch even simpler. I got a mere $400 for the idea due to it not saving any money (If it saved even one ship, it was worth a BILLION dollars, but no such luck). Thus, I created what eventually became, when improved and the launchers eliminated, Vertical Launch Capability in Aegis and ESSM.

[@timkohchi2048]

at 1:40 ish you imply the timer on the fuse on a 5/38 is “ticking” once set, and so haste is required for accuracy. Doesn’t the timer begin counting once activated by the spin of the shell after firing?

[@Drachinifel]

Yes, what I was pointing out is that the timer setting is good at the time it has been set. Every second between then and the shell being fired is leading to more and more of a difference between the time calculated on the fuse and the actual postion of the aircraft.

2:27:14 Marked sails were much more of a thing in the mercantile fleet, particularly as ship designs became more and more similar for speed, both as a form of advertising and as an identification to allow the shore staff for a shipping line or a whaling firm to call up personnel to load/unload a ship when it came into port.

25:55 To add, even if the British didnt actually intend to follow through qith saying they were going to stop impressment of any Americans, by 1815 that was a moot point anyway. Peace in Europe meant the Royal Navy was entering a large drawdown so they no longer had any need or reason for impressment and they wouldn't reintroduce such a system until conscription was introduced (for both the Army and Navy) in 1916.

[@alganhar1]

Impressment was never really a reason, it was an excuse to present to the American public as a causus belli. A certain proportion of the US elite wanted a war with Britain as they thought, given that Britain was pretty much engrossed in the Napoleonic war they could grab what they wanted and deliver a fait accompli within short order.

For "Blocking a narrow passage in the Age of Sail?" there's also the Battle of Lake Champlain (the Naval part of the Battle of Plattsburgh); as the last naval battle of the War of 1812 involved an American squadron anchored to defend the American base on the lake against a British squadron. The ships of the American squadron were anchored in a way that they could spin around, and the American flagship did so to present an undamaged broadside to the British flagship at close quarters (the British ship tried to do the same but failed). The technique to spin the American ship was 'winding' and not 'springs', but it was a decisive application of seamanship by the American squadron.

The position of “ oil king” is a position that still exists on modern ships. It is held by usually one of the mechanical ratings, such as machinist, mate or gas, turbine technician. Their duties include sampling and testing of all lubricating oils and similar products used on board ship. They are essentially quality assurance for oil. they will do research testing as viscosity, “oil, color and suspended solids”, transparency (looking for a water), and other tests.

Growing up and living on the Isle of Wight (which has very extensive coastal fortifications ranging from the late medieval to WW2 periods), British coastal fortifications have always been a bit of an interest of mine, and I was a bit puzzled by your section on British coastal fortifications. Absolutely, Britain has generally relied on the Royal Navy for defence, but there have also been periods where extensive coastal fortifications were developed, particularly along the South Coast, in response to fears of invasion. Henry VIII's Device Forts included not just harbour defences, but extensive earthworks overlooking likely invasion points. There was also extensive fortification done in the 19th century, not all of which was focused on major harbours, with the Palmerston forts, Martello Towers (including quite a few in Kent) and so on, and fortified barracks, logistics infrastructure and inland fortifications designed to provide depth of defence. During WW1, Kent had multiple lines of anti-invasion trenches, as well as other fortifications, and there was even more extensive fortification during WW2.

Now before everyone starts foaming at the mouth, I know there is no direct correlation from small arms to naval guns....

On the question of a seaplane tender/commerce raider. Another issue you might run into is a seaplane tender belongs to a navy. I commerce raider is often disguised as a merchant ship. If you are spotted, a seaplane tender would be MUCH more likely to be investigated than something that looks like a friendly freighter.

[@TheAnxiousAardvark]

Fair point. There are a number of "If's" that came to mind as Drach talked about the idea. For the raider the vessel would either have to be purpose built or heavily modified internally. For the ship one possibility, something like MS Schwabenland a catapult ship used as a refueling ship for trans-Atlantic Dornier Wal flying boats. The Wal or BV.138 are big, but could be catapult launched. Practical? No. Mad as a box of frogs? Yeah. Worth the effort? Probably not, but the chaos it could create until captured or sunk? No way it would pass close inspection.

Imagine how tall shot tower would have to be for a 32lber

[@timengineman2nd714]

Those. were cast, not drop formed....

[@StarlightSocialist]

I love questions like this. So you want a shot tower for cannonball sized lead droplets. How tall would the tower need to be? Let's say that a 100ft shot tower can make 1 inch lead spheres. (Arbitrary values). Now let's scale up the 1 inch spheres to 10 inches. The surface area of the sphere has grown by X^2 but the volume of the sphere increases by X^3. (The square cube law, we meet again) This means the 10inch sphere has 1000 times the volume holding heat and only 100 times the surface area radiating it away. So the 10 inch sphere needs 10 times the cooling of the one inch sphere; it needs to fall for 10 seconds, not one. It actually takes 2.5 seconds to fall 100 feet, so how long of a distance is 25 seconds? Punch that into the calculator . . . . 10,054ft! That's two miles high, with 5000 freedom feet per freedom mile. These are all arbitrary values, and you didn't ask about diameter of lead shot but weight of lead shot. The 10 inch shot would weigh 214 pounds of freedom. A 32LB shot would have a diameter of . . . .5.3 inches. That's not that bad! It only needs to fall for five times however long it takes for a one inch lead shot to cool. Do any shot towers make 1 inch shot? No, not even close. Let's do some more mathcrimes. 2.4mm is basically 1/10 of an inch and 40 meters is kinda close to 100 feet. (Actual 40 meter towers can produce actual 2.4mm shot) Five inch lead shot is scaling that up by a factor of 50 . . . As we've seen, scaling up by a factor of ten got us a two mile high tower or 100ft multiplied by 10^2. 100ft multiplied by 50^2 is . . . .a very big number. Just go with the two mile high tower and figure out a way to get 5 times the amount of cooling done during the fall.

[@juangonzalez9848]

@@StarlightSocialist At that point it would be easier to figure out how to make a vertical wind tunnel to cool it “in flight” instead of making it a 2 mile tall tower. The fluid dynamics involved in keeping the molten lead from splatting on the walls would be mind boggling, but easier than a 2 mile tower.

[@Drachinifel]

I will investigate

[@robertandreasen6023]

@Drachinifel personally, a 15 second add in the middle of a 3 hour video doesn't bother me. Especially if it brings in a bit more cash for your efforts. I only mentioned it because I remembered you saying that you addimently against allowing add interruptions during your videos. Thank you for all you do. Yours is one of my favorite channels.

I can't believe I watched all of part 1, then have come here for part 2. I'm not a warship fanatic, or whatever you want to call it. I just think Drach does such a good job that it's really interesting and yes, historically educational. I'm much more of an aviation nut. But maybe I've seen so much of that, that this becomes more interesting. And sometimes, fascinating. Also his use of British humour (yes I know it's "humor" but what the hell) is quite decent. :)

2:24:00 Iowa class was panamax, so I assume most cruise ships up to recent want to be, up to 90.000 ton cruise ships can fit this. I assume its because they are more boxier than an Iowa.

[@Dave_Sisson]

The largest cruise ships today are over 250,000 Gross Tons or four times the size of the 80,000 GT ship Drach discussed. But they are the mass market ones, premium ships are under 150,000 GT and luxury ones are well under 100,000 GT.

When USS Hornet was found there was a 5" shell still in the fuse setter of one of the 5" gun tubs.

Love the reporting on the War of 1812 … Any war like this that is “won” begets the question ‘at what cost?’. The US held its own but the fighting stopped long before there was a unilateral “winner.”. The better way of winning an international argument.

[@lllllIIIIIII]

Very much reminded of the curious logic I sometimes hear about America supposedly winning the Vietnam war. I see it as a draw myself -- the costs tremendously outstrip the gains -- but if one of the two sides won, it was probably the side that gained nibbled bits of Spanish territory and some indemnities. Typically the winnings go to the victor, no?

[@vikkimcdonough6153]

In addition to part of the space formerly used for boiler room B-1 having been reclaimed for other uses on WWII _Texas,_ it also looks on that diagram like the floor of the boiler rooms's been raised somewhat to create an additional tank layer underneath the boilers?

[@Dave_Sisson]

I thought that was for the possible Tiki Bar that Drach mentioned?

[@sconner5424]

@1:07:00 you referenced a USN study on the effects of blast pressures to the human body. When was this study conducted? Was there any attention paid to head trauma? Specifically mTBI? I know that common knowledge of the deleterious effects of repetitive blast exposure in service members is a relatively (>20y) new thing and am curious if it was recognized in this study.

[@timandellenmoran1213]

Near the end of this video you talked about the problems of AA weapons on aircraft carriers that must not interfere with the aircraft activities, such as mounting the many small AA guns of WWII all around the edge of the deck. Some earler carrierws of US make actually had 8" guns mounted near the small cuperstructures of these ships to try to allow some form of self-protection. This was eventually realized to be inefficient and the guns reduced to the much better AA guns of 5"/38 type. However, in the US there were still people who wanted self-protected carriers after WWII. Somehow these badly-mistaken people actually got THREE (3!) carriers built with the rather large and complex TERRIER AAW guided-missile systems installed, again around the edge of the deck. BIG, BIG, BIG MISTAKE!!! Such missile systems with their rather large radars and launching systems scattered around cost a large amount of space on the outside and, for the magazines and control systems, inside the carriers. And, as you could imagine, those big missiles (12" in diameter and over 10' long), if used, made a very large region around them not suitable for any aircraft at all. The captains of those ships said "Bullshit to that nonsense!" and in effect turned them into unusable storage spaces for aircraft parts, so they could not ever interfere with any aircraft operations whatsoever. Eventually, they were removed. Sometimes you wonder how some people who are supposed to be good engineers can be so dumb...

Is that book, talking about the spring anchors, The Mauritius Command?

[@edwardloomis887]

Ref: the U.S. destroyers deal, the Drachinifel response characterizes them as a group very well. But something I didn't realize as a young person reading about the raid on St. Nazaire, HMS Campbeltown (formerly USS Buchanan) was one of the U.S. four-stackers adapted for the mission. I can't think of any American who is going to have a problem with a U.S. WWI destroyer being turned into a bomb that destroys the only dry dock that can handle biggest Kriegsmarine ships.

[@noblereflex8332]

As to the Naval War of 1812, While I agree that Britain won the war, In fact one of the main reasons for the RN's early failures was because it was mainly concerned with beating France and as a result of it's constant success held the US navy in low regard. Once France was beaten there was nothing stopping the RN from bringing it's full attention on the US. If I remember correctly Roosevelt's conclusion was that the US showed that despite their navy's small size they would not be a walkover and that diplomacy would be better than war.

When dealing with solid objects, the square-cube law can have very negative effects, as the weight of the thing is going up much faster than the underpinning where forces are coming from (underneath if gravity, from the side if a gun projectile in the barrel). This means that the area where the force is pushing or pulling the object is getting smaller compared to the object weight as it gets larger and much heavier. This is why elephants have to have such thick legs and can require greatly increased structural weight in things like guns to allow big guns to not blow up when fired. This law has to be carefully applied to anything that can get big when needed.

Re: the Lancaster barrels, have any naval guns used hammer forged rifling since its easier?

[@thomaslinton5765]

70-pounder Whitworth naval gun Place of origin United Kingdom Service history In service 1863- The 70-pounder Whitworth naval gun was designed by Joseph Whitworth during the 1860s. It was a rifled muzzle loader and used his hexagonal, rifled-bore design. The gun used polygonal rifling, a principle invented by Whitworth in 1853. The concept was to use the hexagon to impart a very rapid spin to the projectile.

The aa crews on the yamato had to wear protective clothing because in testing some men lost skin. And they added gun tubs around the aa guns

02:57:44 While it is true there were no organized large scale evacuations conducted by the allies in the far east in the beginning phase of the Pacific war because, as Drach points out, the lack of Allied naval and air power to even offer token protection to any such efforts, there were a large number quixotic and perhaps heroically foolhardy small scale and individual attempts. One source states "It is said that 44 ships carrying evacuees left Singapore between February 12 to 14, 1942 and that of these vessels, all but 4 were bombed and sunk as they passed down the Bangka Straits from Singapore to Java. Thus thousands of men, women, and children were killed before any could reach land." This includes the last time a British naval officer (reserve) actually offered his sword in surrender to the victorious enemy. One of the rare occasions (only?) when an imperial Japanese officer genuinely seemed to want to avoid unnecessary bloodshed. These stories might be worthy of video or at least some of the ships involved deserve a 5 minute guide with actual human voice.

One of the 5/38 turrets on the USS Alabama fired into another turret causing the only fatalities on the ship during the war. I do not know if it was a malfunction.

At 02:19:22 the question is about battleship tonnage. It appears that there needs to be some real explanation between 'Gross tons' and weight of ship. For all commercial ships, 'Gross tons' is solely a volume measure, and it has almost nothing to do with its weight, which is the same as its displacement. It is confusing that they decided to use the term 'tonnage' for commercial ships because normally the term 'tonnage' means weight, but it does not meant weight for all commercial ships. For all military ships, the term 'tonnage' is the actual weight of the ship, and has NOTHING to do with its volume. So, in relating this to today's very large cruise ships, today's biggest cruise ships approach the weight (displacement) of the US super carriers, which is about about 100,000 tons (real weight/displacement). These cruise ships are advertised around 230,000-250,000 tons (volume measurement), which really weigh about 100,000 tons in displacement (it is nearly impossible to find their actual weight). So, with the cruise ships, as the tonnage does up, it usually is reflected in their length getting extended, but mainly in their height also getting extended, and that is how they get the large tonnage figure as the volume goes up drastically. In addition, these very large cruise ships of today are about the same length of the US Super carriers - between 1,000-1,100 ft long.. Compare this to the Iowa class battleships that are only 887 feet long and are 57,000 tons fully loaded, and the WW II Essex carriers were only 820 feet long and 39,000 tons also full loaded.

Unusual point about the British 9.2" gun APC Mark 12 shells used in WWII. To minimize costs it was decided that the new British 9.2" APC shells just mentioned would be of roughly the same manufacturing quality as the new 14" and 15" shells, but otherwise be internally designed and the same weight as the old WWI-era shells with their much larger explosive volume inside. This should have made those Mark 12 shells act more like SAPC shells (similar to the British 8" SAPC shells of WWII). But, amazingly if did not! These shells, for their size, turned out to be about the best APC-type British shells as to their ability to penetrate INTACT heavy armor. I think that the British APC shells of WWII needed more work...

Concerning the effects of sloping side armor. By the 1930s projectile and armor testing of most nations using such heavy armor had progressed to using 30 degrees for the test plates against whatever shell types they used for such testing. Thus hitting at angles up to 30 degrees from an enemy ship of one of those nations was "baked into" the designs. Thus, while smaller angles did indeed help the resistance somewhat, there was not that much improvement in the velocity expected to defeat it by well-designed AP shells. What the angling did was add to the angle of fall so that the total angle, expecially if the ship could add a horizontal angle by not being broadside-on the enemy ship, gets at or near the 30-degree point. At this point, AP shells, which were usually also only tested to that angle -- except for the new US AP shells tested at 35-40 degrees (WAY better than most foreign AP shells!!) -- would have the secondary effect of causing major damage to the middle and base of the shell as it was violently "refracted" by the armor to more of a right-angle path as it pushed through the plate. Many non-US shells simply snapped in half near and over 30 degrees unless they hit at a much higher velocity to minimize this refraction effect. Thus, the shell might get through but not explode properly or even still be in one piece, drastically reducing the damage inside the ship if the ship had some light interior fragment-protection plating behind the main armor. Keeping the deck high also reduced the unprotected amidships volume that could be destroyed and thus yiou had to make a rather large hole through the main armor -- side or deck -- to cause the ship to begin to lose floatation. The BISMARCK had better side protection at close range to its underwater systems by the sloped deck it used, but it had an entire upper deck that could be riddles by even small fragments of big shells going through the rather light upper hull armor, and thus have major floatation problems due to hits that the higher-deck designs would just shrupg off. Not good!

Defending a harbor with a reef thereby a narrow passage using as you just said spring anchors I can see an obvious problem with that. The enemy could sit outside the reef and fire broadsides at your ships outside The Reef.
