Given the amount of plates rejected, the plate quality overall is concerning

#

What baffles me is people who write it off just because the armor isn't face hardened, as if that was the be-all, end-all way to build armor.

#

I stand by my statements that against well-capped, well-designed shells, homogenous armor is the way to go. You don't waste thickness with a pointless cemented layer that just shatters without contributing anything.

#

(the entire ongoing history of steel armor, which is used all over the place but not at sea against shells anymore, would back that claim up. But the "common knowledge" base of naval armor designers is stuck in the veeery early '40s as that's when development ceased)

tough quail
#

ive been pointing this out too

cinder escarp
#

Something that would really throw off old naval armor designers would be like modern Super Bainite armor steel

tough quail
#

👀

cinder escarp
#

Back in the old days, bainite was something to be avoided at all cost

#

Because it's so very brittle it delaminates, cracks, and shatters with ease.

alpine onyx
#

I hear Schleswig Holstein

cinder escarp
#

But we've taken the bainite phase of steel, but kept the grain so fine that it can't shatter or delaminate, as cracks can't join together.

#

It hits grain boundaries.

#

So you get a very hard yet tough steel, with a microstructure that would cause old armor designers to spasm

manic latch
cinder escarp
#

Here's normal bainite, and the "plates" are vastly larger.

#

This scale is literally 10x the super bainite pick up there

spring briar
#

looks a lot like tempered martensite

#

so if I got it right
they made it so the ferrite in standard bainite becomes marsensite

#

with bainite plates between those

#

the bainite keeps it all tough
while the martensite acts as the hardened material needed for armor

It's actually the result of very carefully cooling martensite with extremely pure, silicon-doped steel.

https://patents.google.com/patent/US20130167983A1/en

#

The silicon doping is key to keeping the ultrafine grain size that makes it work

spring briar
#

every time I hear silicon in steel I just think about early warship armor

cinder escarp
#

Super bainite is funny, because both in being bainite in structure and by being silicon-doped it goes against two major rules of what to avoid in good armor steel.

spring briar
#

and what would those two rules be to you?

#

I'd assume the high silicon content is a no no usually

#

and upper bainite is known to be brittle

sounds like some pepega steel ngl

ngl, that sounds like a bit pepega process when in the finished product it still has some of the old bainite properties retained. Not to mention the silicon doping, something that even the blacksmiths of old tried to prevent of their steels.

Like, I get it they wanted to have that balance between strength and ductility for armor, but with through-hardening, you can easily play with that when you temper the plate.

#

(apologies if I'm a bit off with my understanding since I got it when I did some hobby smithing a few years back)

cinder escarp
#

It's a very strange process but the end result comes out very well

#

The silicon is normally bad but is critical to the ultra-fine grain size that makes it work, and in this case is a net benefit.

essentially, a hardened armor would be stronger and have more resistance to a certain point. if it was pushed beyond that, i expect the entire plate would just break and you would lose all of your armor, instead of being able to absorb the hit while keeping the rest intact

chilly osprey
#

Mmm, this is why even historically hardened armor only have the front layers of the plate hardened, while the back was kept much softer. This meant the plate would be less brittle and ultimately more resistant than a completely hardened plate.

it was even found that having an extra thick (thicker than usual) cemented face layer on your armor would make it (even if it is WW1 era armor) about as good as compound armor

#

so basically it got ditched for being too expensive and not good enough

#

even though the xm1 was also not actually good enough and they had to pile on upgrade after upgrade to make it half decent

#

all the arguments for the 120 not being an upgrade went up in smoke pretty much immediately after the abrams went into service

essentially it's correct in a bubble and incorrect in the greater context of armor development of the late 70s and early 80s

tough quail
#

if it does then it's a case of mutual painful dumbassery

strong plank
#

Oh wait, so it’s got radar for the back

#

that makes sense given that the RCWS creates a blind spot for the turret-top sensors (I’m not sure what the technical term is)

tough quail
#

straight up radar in tanks is always cool

strong plank
#

Well I’d seen a comment or two pointing out the blind spot

#

so it’s nice to see that they’ve already got it handled

spiral cedar
#

Ablative turret is the new meta

#

presumably you'd wanna pair it with APS that can engage top attack profiles

tough quail
#

the thing that wigs me out is

#

okay, there's nobody in there, most of the sensors and the barrel itself are already basically impossible to protect by armor

#

....

#

but all the ammo is in this one

spiral cedar
#

What's the estimated armor protection for the turret anyway

#

Because surely, at minimum it needs to stop typical APC/IFV autocannon rounds

tough quail
#

i haven't seen a concrete general rating yet but i'd be shocked if it couldnt, maybe stinky 100mm guns from light tanks ideally

strong plank
#

the turret doesn’t seem to be much smaller than that of a normal Abrams, so I can’t imagine they cheaped out there

#

It does also have blowout panels like a regular Abrams

tough quail
#

im watching the source atm it's an interview

#

tl;dr

#

the tank weighs 54 tonnes

#

and the primary weight saving is pulling most of the armor out of the turret

#

with a question/statement to the army of "if you want this armored like an abrams turret, its going to weigh like a current abrams"

spiral cedar
#

I wonder how much the autoloader weighs compared to a crewman

chilly osprey
#

depends on the crewman

strong plank
#

Yeah I’d imagine the autoloader adds a chunk of weight

tough quail
#

its in line with current asian mbts weight wise

#

but instead of no side armor its no turret armor

strong plank
#

I guess that kinda makes sense if they did reuse a chassis they already had

#

maybe they figure prospective clients may favor hull armor over turret armor

#

it is a technology demonstrator after all

tough quail
#

(the hull armor isnt good either)

#

the more i think about the stranger a choice it is, the turret cant be hidden like the hull is and even with the blowout panels a penetrating his is going to put the tank out of action if not total it

frigid karma
#

good god discord hates playing videos for anything

tough quail
#

it really do be like that

frigid karma
#

and good god instagram's media player is even worse

#

switch to another tab for a second and it restarts

strong plank
#

Ok so basically he says they removed the turret armor with the expectation that the army would probably add however much they want back on

#

Which makes sense from GD’s perspective

#

Basically giving them a bit more flexibility

tough quail
#

correct answer is probably put all the armor back on and eat the weight or peel it all off and go with a carousel and beef up the side armor a bit

spiral cedar
#

Give each turret a random amount of armor so that the enemy won’t know if they will overpen or bounce TapNoggin

strong plank
#

I mean I really doubt the army’d go with a carousel

strong plank
#

given experiences from desert storm and [current event]

tough quail
#

its definitely a better option than this layout

frigid karma
#

if the army wants to save weight though, it's likely for a reason

strong plank
#

Transportability most likely

tough quail
#

though obviously i mean the armata style where its tucked into the back and miles from the crew

frigid karma
#

and they judge that reason to be more important than taking mission kills / total losses through turret penetration

#

if i had to guess, the weight constraints came specifcally from having in mind amphib operations

strong plank
#

I mean with the bustle autoloader+blowout panels, if the ammo detonates you’re still only losing the turret, no?

spiral cedar
#

I say we go to the good ol’ days South Dakota standard. 18” front, 9.5” sides, 12” rear, 7.25” roof, no compromises

frigid karma
#

then again, i'm not a tank expert

tough quail
#

a t-14 is around that 50-55 ton mark too so shifting the autoloader into the hull and keeping the turret slim is definitely an option

frigid karma
#

we're long past calling them landships jaba

spiral cedar
frigid karma
#

go sit on your boat

tough quail
#

it can easily backblast and burn your engine to a crisp too

strong plank
#

should I be concerned how quickly you had that image pulled up

tough quail
#

or your crew if its turned the other way around for some reason

#

...and i dont think blowout panels like

#

work at all if they're penetrated from the front

#

so you're likely losing everything

strong plank
#

I’d assume whoever’s designing it has some insight in what direction the army’s looking in their design studies

#

Hence the emphasis on shedding weight and increasing range

#

plus if the army looks at the lack of turret armor and considers it a problem(which they probably will given their penchant for prioritizing crew survivability) then it’ll be addressed in whatever design they do adopt a few years from now

tough quail
#

well yeah

#

im not saying they're gonna use it

#

just the idea is currently uhh

#

dumb

frigid karma
#

At that point, there's not much in the way you can do to stop a misison kill at the very least

tough quail
#

well yeah but a frontal pen is just going to kill everyone inside

#

since there's actually a direct link to the crew and the turret so a guy can still climb in

#

which is probably why the turret didnt shrink at all

frigid karma
#

yea

#

do we know if the crew has armored compartment

#

i haven't seen that comparison to t-14 yet

tough quail
#

i like the redundancy of being able to do a manual takeover of the turret but with a bustle autoloader is compromises the crew protection

#

unless there's an enormously beefy hatch there

#

i'd be VERY surprised if they didnt have a compartment like that though

frigid karma
#

yeah but it's just weird that

#

no one has mentioned it

tough quail
#

i'd like to think it's just what you'd expect by default

#

if its thats

#

a weird waste

#

like yeah sure its not as vital without an internal autoloader but side pens still exist

#

plenty of flammable shit to tuck behind a bulkhead

#

but i guess they wouldnt be able to get into the turret then

frigid karma
#

if i had to guess, the drop in weight is likely a necessity for future amphibious operations

#

the US wouldn't see any reason to drop armor besides that

spiral cedar
#

Isn’t it an offer for the army rather than the marines

tough quail
#

they always say army yeah

strong plank
#

Also yeah the marines ditched tanks

#

be kinda a waste to design new ones for em

spiral cedar
#

A light tank may fit their mission profile, but 50+ tons probably not

#

So I doubt this is targeted at them

strong plank
#

I mean the marines basically said “if we need tanks, we’ll get the army to do it”

#

So it could have amphibious stuff in mind while still being for the army

frigid karma
#

if the marines needed an armored breakthrough tank suited for amphibious operations, they'd need tank that hit the compromise between crew survivability and weight

#

and i suspect they designed some of the aspects of this tank with this in mind

#

since the marines might need to borrow tanks from the army, army always needs to keep marines in mind when asking for tanks

strong plank
#

Well no qwerty they wouldn’t borrow tanks from the army

#

They’d get army units to conduct whatever operations they’d need

Do torpedoes actually spread like in majority of naval games? (launch at 1 go, spread out like a shotgun.. I don't think that's how torpedoes travel?..)

I know they'll stray off their course midway by nature, but they don't immediately turn after they land in the water, right?

Torpedoes have gyroscopes to set them on their course once they land in the water.

That's why you have a couple unfortunate cases of the gyroscope malfunctioning, circling back entirely and crippling the launching ship.

Torpedoes of the WWI-WWII era generally travel in a straight line, but navies deliberately spread their salvo out over several degrees to increase the chance of a hit, due to the risk of errors in the torpedo solution as well as the likelihood of enemy maneuvering. The only reason you would not is in effectively a scuttling scenario where you just want to launch two torpedoes at a static ship at short range to put it to the bottom. Otherwise, you launch over a spread of a few degrees to increase your hit chance

and "normal" AP is already more fragile than anyone realizes

Commissioned into US Navy service in May 1942, Wahoo has had a phenomenally successful career. Her skipper, Dudley Walker Morton, has made a name for himself with his aggressive tactics. Before departing Brisbane, Australia, on his first patrol as commander in January 1943, he declared that the submarine was expendable. Any man who did not wish to sail under that assumption could stay ashore.

This attitude brings impressive results as Wahoo preys on Japanese destroyers, freighters, and submarines. By the time she goes down, the submarine is credited with 19 vessels and nearly 55,500 tons sunk. This makes her the most successful submarine in US Navy history.

But Morton’s legacy is tainted by an incident on 26 January 1943. After Wahoo sank the transport ship Buyo Maru, Morton ordered the boat to surface and machine-gun survivors in lifeboats. This was a breach of the Hague Convention of 1907. The situation was made even worse because some of the men were British Indian Army POWs under Japanese guard.

Wahoo’s downfall comes after she sinks the steamer Konron Maru, on 5 October, killing 544. The Japanese Navy seeks vengeance on the US submarine force. Today, Wahoo is spotted from the air. She has already been damaged by a patrol boat a couple of days ago. Now, destroyers and aircraft hunt her down with bombs and depth charges. Eventually a Japanese aeroplane scores the kill.

Her loss spooks the US Navy. No more submarines will be sent hunting in the Sea of Japan for quite some time.

The name "British" should be capitalized, as it is a formal name. Just like American, Canadian, Dutch, etc.

A…kinda strange thing to get at the beginning of an email reply VickyXD

#

The name "British" should be capitalized, as it is a formal name. Just like American, Canadian, Dutch, etc.

I did not know the information given for the 12" US AP shells prior to 1916 when the 12" Mark 15 MOD 6 Midvale Unbreakable AP shell was introduced, making all prior 12" US AP shells instantly obsolete. All later 12" AP shells were the MU shells, so I think that older shells, either earlier Marks or 12" Mark 15 MODs 0-5, were declared Unserviceable and removed from the US Navy inventory within a short time after mid-1916.

I do not know if Crucible Steel made any 12" AP, but I would bet that all pr0blems noted by me for the Bethlehem 14" AP designs were also happening to their 12" AP. In addition, if any of the 12" Mark 15 MODs 0-5 versions were made by Midvale, I would assume that they would usually pass the 10-degree spec, though possibly with some failures. The fact that the Midvale-made US 8" Mark 11 MOD 0 AP shells of 1911 were found to be almost as good as tha 12" Mark 15 MOD 6 AP when retested during and just after WWI, shows that the improvements for the Midvale 14" experimental AP shells of 1910 s-pec design were being implemented in the other sizes, almost completely in the 8" shells the next year and partially prior to 1916 and completely for the MOD 6 versions of their 12" Mark 15 shells in 1916. Note that there was an almost identical-in-design 12" Mark 14 AP shell, so I think that the difference between then Mark 14 and Mark 15 was likely just the new 10-degree test spec requirement.

#

Note that only Bethlehem complained about the new 10-degree test spec for any size shell that they and Midvale made. As mentioned, its armor quality control circa 1912 was shown from the plates taken from OKLAHOMA after Pearl Harbor to be very poor, so having poor projectile quality seems merely "par for the course" for them. Since you do not know what ships had the shells made by which manufacturer, perhaps you need to roll a die with a 50/50 chance (or worse, depending on how many each manufacturer made) of projectile body breakup during penetration at 5-15 degrees penetration angles (over that and the soft AP cap does not work for any of these shells).

#

As for British and US naval 12" and 13.5"/14" AP shell comparisons prior to 1916 and the British "Greenboy" improved APC shells introduced after Jutland (mid-1917 and after, depending on the shell size), we have some conflict as to what the s-pecs meant.

US Navy specs were for the shell penetrating the armor in an "Effective" (British "Fit to burst") condition where no damage occurred to the middle body or base so that the explosive filler was not compromised nor, if used, the base fuze damaged (I do not think that they tested these shells with either an Explosive "D" (ammonium picrate) filler or non-delay base detonating fuze inserted (no delay was the standard US pre-end-of-WWI and British pre-Jutland type and only gave about 0.003-second between imp[act and full detonation, where British Lyddite virtually always detonated due to excessive sensitivity, but very insensitive US Explosive "D" had problems getting full detonations until 1928 when Tetryl high-power boosters were developed -- only Germany started to use rather poorly-designed and unreliable delay-action modifications with black-powder wafers in their latest 1911 and after APC shells).

#

The US did not test for bare penetration in any condition nor for merely holing the plate without completely penetrating it. However, the British tests were different: They had three levels of projectile performance, but only spec tested for the lowest, at right angles to the plate face prior to the Greenboy APC shells. These were:

 (1)  "Penetration" Limit (US Navy term "Holing" and US Army term "Army Ballistic Limit*"), whereby the projectile barely punched a hole entirely through the test plate and the condition of the projectile was not important. (*This included for the US Army spalling on the inside of the armor that caused significant damage behind the plate even if a hole was not made entirely through the armor plate.)  This was the minimum used to test armor.

 (2)  "Perforation" Limit (US Navy "Navy Ballistic Limit"), whereby the projectile barely makes it entirely through the armor plate, no matter what damage it has suffered.  This was the minimum used by the US Navy to test armor.

 (3)  "Fit-to-Burst" Limit (US Navy "Effective" Limit), whereby the projectile passes through the plate at the minimum velocity that would allow it in a naval battle where it hit the given plate at the given angle to detonate properly by fuze action.  This was the only one the US Navy tested projectiles for.
#

Prior to the deletion of Lyddite and the introduction of delay-action fuzes (the optional delay version "D" of the APC Number 16 Base Fuze), the British test specs for their older APC shells (this was known by virtually none of the ship or shore personnel using these pre-Jutland shells or developing tactics with them) did not care about internal enemy ship damage caused by the shell impact energy or its filler explosion. The spec said that the shell was to make a hole at or below the waterline through the armor belt t9o cause flooding of the ship. Remember that when HMS WARRIOR was built in 1860 all "AP" shells were solid shot, mostly cannon balls, so any talk about how the shell's filler would work after impact was not even conceived of. It turned out that up to Jutland nobody had changed the spec!!!

#

After Jutland, when the Projectile Committee went to find out why more British ships had sunk than German ones in that battle, they found out that the then-current APC shells were still being designed and tested to that 1860 spec! The P.C. people found out that the shells were designed and spec tested ON PURPOSE to explode while they are still imbedded in the hull waterline belt side armor or, at worst, just on the far side of the side armor. This would cause the maximum flooding effect from such hits, but only if there was np internal armor to limit the damage to the hull side. Since modern (WWI-era here) warships had such internal plating and/or multiple watertight compartments, this in WWI had the result of MINIMIZING the damage to the enemy ship, not maximizing it. Up to then, delay-action fuzes had not been used (other than as a secret by Germany after 1911) due to the problems with reliability (US problems with getting Explosive "D" to detonate reliably with the rather weak HE materials used in boosters at that time) and, with British Lyddite or other nations that used similar fillers (most, other than Germany of the US Navy), due to the filler detonating all by itself also at about 0.003 second after impact, fuze or no fuze, when penetrating such armor. Thus, for all pre-Jutland British APC projectiles, the concept of Fit-to-Burst quality was a rather lower standard than with US or German or post-Jutland British AP shells. Also, British Greenboy shells were tested at 20 degrees and the original 12" Mark IVA APC shells, which were cast rather than forged to a tougher body strength like the bigger shells, could not remain intact on hitting any armor plates much over 8" at 20 degrees, as was found out after later testing againstthicker plates.

I hope this helps with some of this messy situation.

spiral cedar

spring briar
#

There’s a reason I love imperial russian shells

#

maiden citrus
#

#

My main takeaways (aside from stuff already seen before) are:

US switched 12” AP manufacture to Midvale sometime in 1916, and no later 12” AP Mark 15 was manufactured by anyone other than Midvale after 1916—there is also a subsequent presumption that the older 12” AP stocks were removed from Navy inventories within a few months, though this isn’t directly implied to be documented.

Bethlehem was the manufacturer with the severe issues at 10 deg obliquity, whereas Midvale did not have the issues. Crucible Steel probably had similar issues with its 12” AP as Bethlehem did with its 14”, probably due to inexperience. Midvale’s 8” AP in 1911 was of the same good quality as their later 12” AP in 1916, which shows that Midvale’s 1910 experimental 14” AP was guiding their design of 8” (by 1911) and 12” AP (mostly by 1916) as well.

There was a similar 12” Mark 14 shell that probably was not designed with the 10 deg spec in mind.

Bethlehem was the only manufacturer to complain about the 10 deg spec, presumably because they kept failing it. Their armor QC seems to have been similarly poor at the time, as in 1912 the plates they made for Oklahoma were of poor quality, suggestive of a low quality standard company-wide at the time. Okun’s suggestion is, since the shells were largely randomized when issued, to simulate the Bethlehem shell issue by giving an extra 50% chance for the body to break during penetration in the circa 10 deg range (5-15 deg).

#

US and British AP shell requirements are not directly comparable in the pre-Jutland era because they had different specification standards. The US required shells to penetrate in “effective” condition, and had no standard for “complete but ineffective” and “holing but no complete penetration.” The UK had 3 tests, but only actually required shells and armor to pass condition (a) below, and at right angles, until the Greenboy in 1918.
a) Holing - British shell and armor spec. Just need to be able to see light through the plate; shell condition not important.
b) Complete pen - US armor spec. Shell gets through plate, condition not important.
c) Effective pen - US shell spec. Shell gets through plate with no middle body, base, cavity, or base fuze damage.

Thus one cannot directly compare penetration velocities between US and UK shells of the pre-Jutland period, because they are testing for very different end states of the shell and armor. The British pre-Jutland shell spec was lower than US, German, and post-Jutland standard due to the lack of “fit to burst” requirement.

Greenboys were tested at 20 deg, and the original 12” Greenboys could not penetrate 0.67 caliber armor at 20 deg (curiously, this is the German 1911 standard—0.67 cal at 20 deg).

USS Brooklyn was the only US ship to be designed with her turrets in a lozenge arrangement. Thanks to the extreme tumble home of the hull, the wing turrets could fire directly forward and aft. She put this to good use at the Battle of Santiago, where her captain, Francis Cook, reported that "our tumbling-in sides enabled us to maintain continual fire while turning."

I’ll look into the 8” shell a bit tomorrow

I wonder how extreme the tumblehome is Thinkpitz

It could also have been put into storage first while the usn used up its existing stock of old 8”
Or have been export

The tumblehome hull and "lozenge" arrangement were rare in the US Navy, but at the time were prevalent in the French Navy and in French-designed Russian ships, such as the French Magenta and the Russian Tsesarevich.[8]

The staff plans assumed that Japanese torpedoes would begin to strike the oncoming American heavy ships about twenty minutes after the vanguard fired its torpedo salvos. At that moment, Japanese battleships, having approached to within 35,000 meters of the American battle line, would open up with their main batteries. Using aircraft as spotters, the Nagato and her sister ship, the Mutsu, could inflict significant damage, the navy staff concluded, starting at 35,000 to 34,000 meters, while the American battle line would not be able to respond until about 31,000 meters, the assumed range of the Colorado class.

In principle this shouldn’t really stop them from making BB caliber shells of different design, but idk maybe they didn’t want to make new drag functions for them

Some 5” usn shells were boat tailed tho

In WWII or later?

Not sure

Its mentioned on the 5”/38 page on navweaps

Rounds were normally 5.25crh. Some rounds may have been slightly boat-tailed.

Get dat Shimose action

And black powder

#

Shimose was used in the ap and black powder in the he

#

But shimose had a tendency to blow up in the barrel

#

So at tsushima most shells fired were black powder filled HE

#

Thinkpitz Not sure which exactly, but I guess shell wall thickness? Doesn’t seem otherwise inherently different

spring briar
#

They also seem a bit shorter

Shorter makes sense since they are about 9% lighter
