A little background on myself,I have a Masters in Nuclear Engineering and am currently conducting research in 4th generation nuclear reactor technologies.
With that being said, the Little Boy nuclear weapon that was dropped on Hiroshima - a gun-type weapon - could not have physically worked, and in fact DID NOT work.
Let me explain:
The concept of a gun-type nuclear weapon is that a partially-hemispherical target of U-235 is impacted with the remainder of the hemisphere in a linear method such that the two parts combine into a super-critical mass of U-235. This needs to happen at a certain velocity in order to generate a nuclear explosion.
cont...
Interested
Continued...
This combining of hemispheres needs to occur at a velocity that is well beyond what explosives technology at the time could deliver, especially when the fissionable material was arranged in a linear method and utilized U-235.
For evidence of this, it is important to note that no other nuclear weapons designs since (with the only exception being the atomic cannon more than a decade later) utilize a gun-type assembly. Every other nuclear weapon in existence uses a plutonium sphere-type compresson mechanism as a primary nuclear explosive.
K. Don't keep me posted
>>72194399
it was not 2 hemispheres
it was a stack of discs "stationary" (making a cylinder) within the bomb with an equal length stack of rings of u235 (when "complete" formed a larger cylinder)
>>72194691
so then what blew up the city OP?
>>72194399
Sorry for the long delays, typing as I go. Will find sources if anyone is interested.
It is also interesting to note that early reports of the Enola Gay's flight made no mention of bombs being dropped, and in fact the first recorded mention of a "new bomb" or even a bombing on Hiroshima at all came from American newspapers.
There is also further evidence from aerial photographs shortly after the reported bombing that closely resemble the aftermath of many of the firebombed cities from earlier in the war.
>>72194399
yes and chemtrails are from space jews and slavery never happened and fluoride is from the devil and vaccines give you the gay socialism
so fucken sick of this spam bullshit

I know your boipucci is swollen and raw, but your virginity is gone, no matter how much you wish it weren't true. You'll never forget your mothers boyfriend.
>>72194758
Incorrect, the commonly-cited washer and post target design is not found in any period-documentation and would in fact be liable to fizzle even at the correct combination velocity due to the assembly reflecting neutrons (effectively lowering critical mass) at a greater rate than a hemispherical target
interdasting
semi related would you recommend nuke engineering major? I'm planning on physics and philosophy dual mjaor but actually want a job after school. is there a demand for nuclear engineers?
>>72194399
I'm glad someone is finally bringing the Hiroshimahoax to light. I knew it had to be a huge lie when my history teacher recoiled at me asking basic questions about its legitimacy.
>>72194898
You keep this useless shit off /g.
We have enough of you faggots who can't use Google shitposting as it is.
>>72194808
Is it likely that the city was firebombed as a result of unsuccessful nuclear weapon.
Keep in mind that the Little Boy bomb was the first ever time in history that a gun-type weapon had ever been assembled, and had never been tested. The Trinity device was a plutonium implosion type device.
but Nagasaki was legit, right?
>>72194691
Nigger what is the w33?
For fucks sake there were at least 4 families of gun type U235 weapons made and tested by the Americans alone.
https://en.m.wikipedia.org/wiki/Gun-type_fission_weapon
3/10 troll made me rage
>>72195150
>had never been tested.
Is that so?
>>72194893
THIS. Fuck you, OP.
I have no doubts as to the authenticity of the Nagasaki bombing. The implosion-type design is a physically-perfect method for creating supercritical masses and is in fact still used to this day, and we have the radiological evidence to support a Nagasaki nuclear explosion.
>>72194399
>Nuclear Engineering
Virtually NOTHING to do with weapon design. Go design some pipe runs, you glorified plumber.
>>72195259
It is an absolute fact that prior to the release of Little Boy from the Enola Gay's bomb bay, no gun type nuclear weapon had ever been tested.
>>72195255
As the article states,
>All known gun-type nuclear weapons previously built worldwide have been dismantled.
I said all other nuclear weapons in existence are implosion type (which they are). I also specifically mentioned combination velocity depending on the explosives in use at the time (cordite) not being fast enough for a gun-type weapon.
Lastly, I even mentioned the success of the gun type weapon in the following decades.
For those that don't understand my argument,
LITTLE BOY FIZZLED, THE U.S. COVERED IT UP
But weren't there survivors near Hiroshima who saw a single, incredibly bright flash, and the mushroom cloud, etc?
>>72195846
NOT AN ARGUMENT
>>72195846
WAIT.
DOES THAT MEAN JAPAN WON THE WAR?!?
>>72195124
This is /pol/
Not /g
>now the entire nation dindu nuffin
>>72195862
Nearly every account of a single bright flash is from the Nagasaki bombing, and it is certainly possible that the few reports from Hiroshima (which were not recorded until days/weeks later) were influenced by the reports from Nagasaki. Witnesses lie to feel included all the time
.>>72195974
No, it means the U.S.'s first attempt at a nuclear weapon failed and they firebombed the city to hide the evidence.
>>72195033
no, its correct
hitchens razor
>>72195846
Ok, let's say you're right.
Hiroshima was still annihilated and we had a successful nuke in Nagasaki as an applied proof of concept.
Correct me if I'm wrong, but it seems as though nothing would have changed.
>>72196244
It's okay japan, I believe that we flash-fried you twice.
>>72194691
>This combining of hemispheres needs to occur at a velocity that is well beyond what explosives technology at the time could deliver
Which is what?
Was there no radiation sickness at Hiroshima?
>>72196262
Explain the radiation. And the videos. And the eye witness accounts. Explain why no one else in the history of ever has claimed the cities were firebombed. Explain how a conspiracy like this can be coordinated between two countries at war.
>>72196262
Isn't there a guy who experienced both bombings firsthand?

>>72196673
oh GOD lol
>barefoot gen is literally a survivalists story about the bomb dropping
>faggot OP doesn't know shit about nuclear weapons
What an amazing thread.
>>72196386
A critical mass (spherical) of U-235 is approximately 52 kilograms assuming no neutron-moderation of the bomb casing and related assemblies.
This forms a sphere 17cm in diameter.
The combination needs to occur in less than one microsecond.
The barrel of Little Boy was approximately 72 inches long (6 feet).
The masses would need to be combined at approximately .225 feet (8.5 cm) per microsecond.
This is a velocity of 225,000 feet per second.
>>72196527
What? Why? To what purpose?
It's not like the one in Nagasaki didn't work.
If both worked, or if only Nagasaki worked and Hiroshima was firebombed, the same effect is achieved. Why would anyone cover this up?
Genuinely curious.
>>72196460
Eye witness accounts don't matter. It doesn't prove anything.
>>72196628
kek'd
>>72196853
Get a load of this faggot.
>>72195562
Not tested because the gun type wasn't a new idea and the technology had been around forever (if the lizards who write Wikipedia are to be believed)
>>72196456
No, the pictures you saw were people with severe burns from fire-bombing.
>>72196823
What about neutron moderation of the bomb case and assemblies?
Is it plausible that we did this, and could potentially fire successfully?
>>72196845
There is no purpose.
I have no idea why it was hidden.
Perhaps to keep from admitting that the millions of millions spent of the Manhattan Project resulted in a failed weapon.
Also, a fizzle still spreads nuclear material around the area. Just no nuclear blast or significant yield.
>>72196823
>The combination needs to occur in less than one microsecond.
Why?
>>72194928
>german "humour"
My parents were pretty big in the aviation community in Columbus Ohio growing up I knew Paul Tibbets and Dutch Van Kirk even though he wasn't from Columbus
Neither one of them were men who were given to putting up with bullshit.
And I heard them talk about it, I saw the effects it had on them even as old men.
Op, is either a troll he doesn't know what he's talking about
This thread is fucking hilarious. Now I don't feel so bad for wasting my whole night on /pol/.
Thanks NukeAnon.
>>72196995
Extremely unlikely.
Neutron moderation increased the rate of slow neutrons impacting fissile material and releasing more neutrons. This would require faster combination or advanced bomb geometry that was not present.
>>72196907
In addition, the real war wasn't Japan vs US, it was always Soviet union vs Japan, which is why Japan wanted to open up peace talks with the Russians.
>>72197035
But we did have a successful weapon used in Nagasaki.
I guess I'm at the point where you actually have a decent theory, but it gives us nothing actually useable.
I say we table it, until someone can find a reason why we would lie, especially if we had a successful use in Nagasaki.
>>72194399
>>72194691
Right off the bat you have no idea what you're talking about since hemispheres were never used.
>>72197045
If the critical mass is formed over a longer period of time, the now self-sustaining nuclear reaction tends to blow apart the bomb casing before enough of the fissile material is converted into energy. This is what is known as a fizzle.
>>72197170
Because the media told you it was successful?
Haters kinda getting schooled by some nuclear science in here
Thumbs up one hundred percent
>>72197204
A rod and washer type assembly requires significantly higher combination velocity due to its geometry. A hemispherical assembly was absolutely used (despite what wiki tells you)
>>72197212
Makes sense, but what makes you sure about specifically a microsecond?
>>72197108
Unlikely, but possible. I'd wager as possible as a cover up for no discernable reason.
What about the generations of children being born with defects as a result of radiation?
>>72195115
Even more edgy faggots than usual on /pol. Fuck off .
>>72197425
Radiation is not the only cause of birth defects
>>72197226
Ok. But my question is, to what purpose? What would the US gain from lying? We had a successful bomb in Nagasaki.
>>72194399
>>72194691
>I just read the Wikipedia page on nuclear bombs: the post
>>72196823
standard temperature and pressure critical REST mass/density of u-235 is less than half that
confirmed troll
>>72197462
But there was more birth defects in children born around the area that got bombed. More cancer cases too
>>72194399
I HEREBY SUMMON OPpenheimer
>>72197352
It is due to the rate of neutron release of U-235, in addition to the level neutrons resulting of "prompt criticality" at the point at which the reaction becomes supercritical. It is an approximation, but extremely close to the actual value. (.00000102... seconds)
>>72197560
Power over the soviet union, who at that time did not have nuclear technology. It was a bargaining tool, a powerful one
>>72197045
>The combination needs to occur in less than one microsecond.
this is a meaningless sentence with what DISTANCE must be covered in that microsecond, to say nothing of the microsecond bullshit being bullshit
>>72196580
Underrated
>>72194399
Enriched U bullet propelled by nitrocellulose into a disc of U 235 works just fine, you autistic undergrad student. Tons of energy potential is wasted, but the same can be said for your parents money on school.
>>72194399
So the radiation fallout was just pretend?
I can't take this propaganda anymore senpai.
>>72194399
you are a faggot and this is /x/-tier bullshit right here, OP...
but thought you might want to read "The Jesus Factor" (its not about christianity) which is about this same kind of idea, only you know, the author actually put some work into it.
>>72197688
Formation of the critical mass must occur in that time period.
What this means is that from the moment that neutrons released from mass 1 begin impacting and releasing >1 neutron per collision from mass 2, must occur in less than the 1 microsecond (approximation) so that the now-supercritical mass does not blow the bomb casing apart, once again becoming subcritical
https://www.youtube.com/watch?v=JC9nrH75P_4
>>72197818
Fallout still occurs with a fizzle, in fact more than would occur with a successful detonation.
>>72197842

all you got right now is nice sounding conjecture
>>72197958
In this case, as i posted above, about 8.5 cm (half of the critical mass (spherical) diameter

He isn't lying, theres a reason dirty bombs that potential terrorists can make would be extremely destructive, because the fallout would be massive, even if the explosion is tiny.

It really doesn't, the little boy bomb was so unstable they only made ONE. They realized that if the plane had crashed the bomb would have gone off.
The other 4 bombs were implosion devices.
>>72198146
>first attempt at (an operational use of a) nuclear weapon failed
>>72195709
Cordite wasnt used in the bombs you dipshit.
pretty sure there is some additional material involved inside the core that acts as a fission catalyst.
Like I said, it was all covered up for bargaining powers against the soviets, who at that time were the largest threat to the US, much more than japan.

Should have said that the first time bud. This is going on your perminate record

they used a shitload of conventional explosives to fake Trinity. They even did a test run with conventional explosives the night before to test out their heinous plan. All that shit was faked, look at the trinity videos, it is clearly Hollywood magic.

>Two or more redundant radar altimeters were used to reliably detect final altitude. When the altimeters sensed the correct height, the firing switch closed, igniting the three BuOrd Mk15, Mod 1 Navy gun primers in the breech plug, which set off the charge consisting of four silk powder bags each containing two pounds of WM slotted-tube cordite.

So was all the destruction staged in an elaborate Hollywood film set?
Were all those people with burns actually given sick-ass tattoos instead?
Are the paper cranes everyone leaves at Hiroshima actually a profiteering scam created by the timber industry?
Or am I conflating this with Holocaust Denial?
In fact, the US informed stalin about the weapons before they were even tested, suggesting the motive from very early on. the US did not need to nuke japan, it only did so to intimidate the soviets. The US knew the exact date the soviets would declare war on japan, and they could have just waited.

so are nukes even real or just a scare propaganda ?
>>72199117
Concrete structures depend alot upon whatever internal materials, if any, are binding them together. Without anything in them they are relatively brittle. A small quake could bring them down.
Those wooden gates are probably buring at least their own height into the sub-strata, and the heat / fire only tempered the wood.
It would take a direct hit into them by something sturdier, to bring them down.

>>72199117
funny how the joke went 20 miles above your head
>>72199385
Except that gate was THE ONLY structure seen surviving after a nuke, NOTHING else. Even if the heat didn't get to it, you'd think the density of concrete would offer more protection
Why were two different designs "used" then? Why wouldn't they just make two fat mans right from the beginning if a little boy couldn't work? Even if it could work, what's the point in creating 2 entirely different bombs? Why not just keep it simple and use the same two bombs?
>>72196823
Are you fucking retarded? When you say combination you basically mean force because of deceleration upon impact with the stationary hemisphere. It does not have to travel the length of the barrel in one microsecond. Jesus the fucking wikipedia reading morons ITT.
>>72199534
It was the first project, experimentation was essential.
http://blog.nuclearsecrecy.com/2014/09/22/tokyo-hiroshima/

>>72199662

What I'm saying is that it makes no difference if we lied or not. The results would still be the same.
The atomic bomb was gifted to the USA by aliens at Roswell. This has been proven by historical documents.
>>72199895
At the time, the Nagasaki bomb had not yet been dropped, and there is no way we could have known the outcome.
>>72199881
The implication was that Japs were shit at making western-style buildings, and that extends from the foundation of the building to the walls themselves.
Ancients designed shit to last forever, and the gate is a good example.
>>72194399
OP is right.
It was all a scam by the govt to build the reputation of mosler safe company after the war
> Its safes and vaults were renowned for their strength and precision manufacture: several Mosler vaults installed in Hiroshima's Mitsui Bank building prior to WWII survived the nuclear attack,[2] and the company subsequently produced doors for missile silos and even the vault formerly used to display and store the United States Constitution and Declaration of Independence
https://en.wikipedia.org/wiki/Mosler_Safe_Company
>>72199895
It meant everything, theres a reason Himmler tried to open negotiations with the US, to prevent communism from spreading. Communism was always the main threat, anything that could help the cause was used.

PROPAGANDA
On the day after the Hiroshima strike, General Farrell received instructions from the War Department to engage in a propaganda campaign against the Japanese Empire in connection with the new weapon and its use against Hiroshima. The campaign was to include leaflets and any other propaganda considered appropriate. With the fullest cooperation from CINCPAC of the Navy and the United States Strategic Air Forces, he initiated promptly a campaign which included the preparation and distribution of leaflets, broadcasting via short wave every 15 minutes over radio Saipan and the printing at Saipan and distribution over the Empire of a Japanese language newspaper which included the description and photographs of the Hiroshima strike.
The campaign proposed:
Dropping 16,000,000 leaflets in a period of 9 days on 47 Japanese cities with population of over 100,000. These cities represented more than 40% of the total population.
Broadcast of propaganda at regular intervals over radio Saipan.
Distribution of 500,000 Japanese language newspapers containing stories and pictures of the atomic bomb attacks.
The campaign continued until the Japanese began their surrender negotiations. At that time some 6,000,000 leaflets and a large number of newspapers had been dropped. The radio broadcasts in Japanese had been carried out at regular 15 minute intervals.

What purpose? The CIA was already in operation at that point and well aware of Freud's studies of psychology and how they applied to the whole of the citizenry. Everything shared with the presses went through a filter of what would benefit national pride, and fucking up what would be perceived as revenge for Pearl Harbor would have been a blow to the American psyche. War is a game of propaganda. Just ask the Germans.

GENERAL COMPARISON OF HIROSHIMA AND NAGASAKI
It was not at first apparent to even trained observers visiting the two Japanese cities which of the two bombs had been the most effective.
In some respects, Hiroshima looked worse than Nagasaki. The fire damage in Hiroshima was much more complete; the center of the city was hit and everything but the reinforced concrete buildings had virtually disappeared. A desert of clear-swept, charred remains, with only a few strong building frames left standing was a terrifying sight.
At Nagasaki there were no buildings just underneath the center of explosion. The damage to the Mitsubishi Arms Works and the Torpedo Works was spectacular, but not overwhelming. There was something left to see, and the main contours of some of the buildings were still normal.
An observer could stand in the center of Hiroshima and get a view of the most of the city; the hills prevented a similar overall view in Nagasaki. Hiroshima impressed itself on one's mind as a vast expanse of desolation; but nothing as vivid was left in one's memory of Nagasaki.
When the observers began to note details, however, striking differences appeared. Trees were down in both cities, but the large trees which fell in Hiroshima were uprooted, while those in Nagasaki were actually snapped off. A few reinforced concrete buildings were smashed at the center in Hiroshima, but in Nagasaki equally heavy damage could be found 2,300 feet from X. In the study of objects which gave definite clues to the blast pressure, such as squashed tin cans, dished metal plates, bent or snapped poles and like, it was soon evident that the Nagasaki bomb had been much more effective than the Hiroshima bomb. In the description of damage which follows, it will be noted that the radius for the amount of damage was greater in Nagasaki than Hiroshima.

Then answer why the fuck does is have to travel 225k ft/s along the barrel you moron. You wont answer because you are fucking retarded spreading your disease here. see >>72200149
>>72200677
No interest? You have to remember the time this took place, In japan, honor was everything, surrendering to firebombing would have been disgraceful, only a weapon "Out of this world" would have been a good reason
>>72200960
The combination has to occur at a speed of 225k ft/sec, The projectile must accelerate to this speed by the time it reaches the end of the barrel.
>>72200704
lol that is fucking ridiculous you think all those people would have never said a word. They are not a bunch of lemmings that all worship the emperor, some don't like him they even have a communist party.

Honor was everything, surrendering to fire-bombing would have been disgraceful.
>>72200962
You have a pretty poor understanding of japanese honor tradition if you think lying about your opponent's strength when you surrendur is honorable.
>>72201055
The emperor was seen as a god, the Japanese considered him sacred.
>>72200960
Also, to clarify why implosion weapons actually work is that the force of explosives compressing the core at equal rate across the entire surface area serves to hold the core together long enough for higher conversion of fissile material to energy. This means that the necessary combination velocity is greatly reduced in implosion weapons.
>>72201050
No it does not, It only needs around 1 km/s speed down the barrel.
>>72198711
>"gate"
it's far closer to a gantry and they're called 'jinja'... and it has very small surface area relative to size for the force of a no-direct explosion to knock it down

>>72201434
It wasn't to talk to himmler obviously, because himmler was dead at the time, what I mean't is both Germany and the US knew that communism was the real threat, and anything that would increase resistance to communism would help.
>>72201351
and before you cite your old post, just in case you are actually retarded, explain how you came to the connection between combination time and velocity upon impact, because those two are not related.
>>72200402
Kek what's inside nuclear plants then ? Visited one, didn't seem fake to me.
Plus the part of nuclear in the power mix is huge, where is the juice coming from ?
>>72201168
No, you haven't clarified anything. You're repeating overviews. You're asserting that Little Boy's hollow projectile & insert would have fizzled, and you've offered no actual engineering to back it up.
No calculations. Nothing.
I'm going to bed. If you want to approach this again tomorrow, this time as an engineer, I'd be happy to read through what you offer.
>>72200706
So...why did we drop another one if we didn't think it would work?
I've got one guy claiming the Japanese lied to save face, but we still dropped another one. It doesn't make sense.
How does faking a nuke, then dropping a nuke shortly after benefit us?

>fat man was more effective than little boy, therefore little boy wasn't actually dropped
You realize how retarded that argument is right? You also realize that website supports that fact that both bombs were dropped and you just cherry picked a paragraph to try to support your shit argument right?
>>72201650
Kek
>>72201727
Fat Man was a different type of bomb
So the emperor has no clothes to the extent that a lowly trainee in a related field can see his wagging cock clear and confident (well, enough to mutter his suspicions anonymously to the so HIGHLY educated legions of this queer little website), and yet the nuclear scientists of the USSR felt no need to bring up this deception and embarrass the US? This strange secret has been entirely unmolested, in spite of you implying it is so trivially easy to piece together?
What is morel likely, that the great powers conspired to build a false bomb when they'd just built a working bomb,and won the Japanese to their deception and subsequent humiliation as their cities and martial pride turned to bitter ashes, OR could you be a less clever man than you think? Could you have mistaken intuition for fact and a feeling for a formula?
Anyone whose mind is not a mess of paranoiac blather can see your claim for the self-serving folly it is. If you are so confident, put your name to it and go to war for your truth, fool, instead of churning this cesspool to win yourself admirers of your ripples in the shitjuice.

>Three 6.5 inch (165 mm) smooth-bore gun tubes with 2 inch (5.08 cm) thick walls and designed for a maximum pressure of 40,000 psi (2700 bar) were ordered in March 1944 and received in October. Proof firings, consisting of firing a 200 lb (90 kg) projectile at 1000 ft/sec (300 m/sec) two or three times from each tube, were conducted in December. To hold weight down the tubes were not designed for many repeated firings, unlike conventional artillery.

Its critical mass for a gun type weapon, not so much "critical slam it together as fast as we can" U235 without any neutron generators or reflectors is relatively speaking a slow reaction. Thus you don't need as much precision as other types of weapon designs if you just want to slap excess quantities of subcritical materials together.
Its not efficient, but it works. Its so theoretically sound that they didn't even bother to test it unlike the plutonium based implosion weapons which were first tested with Trinity.
This thread and flavors of it pop up every couple weeks.
>>72201821
So? If we knew gun types wouldn't work, why didn't we just use the other type on both bombs? You think the first thing some general said to a scientist was,
"make sure the first bomb can be proven ineffective by some asshole on the internet, then make the second bomb using the type that works. Thanks."

At this time, Japan was trying to start secret peace talks with the soviet union, but the US wouldn't have that. Japan needed an excuse
>>72202125
And they did surrender, after the successful nuclear bomb. I don't see why this is so hard for you people to conceptualize.

15kt vs a theoretical max yield of what given the design? It wasn't close to an efficient bomb but it still fucked up the city well enough to call it a operational success.
Its like test firing a W88 with the dial a yield cranked and saying it failed when it only yielded 450kt vs 475kt. Yes it is technically a "fizzle" but the design still filled its mission goals of blowing apart the city
>>72202462
Yea right, so much money was spent on the project that results had to be positive.
>>72202462
sure there is
if anything jews have proven is playing the victim while victimizing is a very effective form of extortion.
"When the war ended, it was not expected that the inefficient Little Boy design would ever again be required, and many plans and diagrams were destroyed. However, by mid-1946 the Hanford Site reactors were suffering badly from the Wigner effect. Faced with the prospect of no more plutonium for new cores and no more polonium for the initiators for the cores that had already been produced, Groves ordered that a number of Little Boys be prepared as an interim measure until a cure could be found. No Little Boy assemblies were available, and no comprehensive set of diagrams of the Little Boy could be found, although there were drawings of the various components, and stocks of spare parts.
At Sandia Base, three Army officers, Captains Albert Bethel, Richard Meyer and Bobbie Griffin attempted to re-create the Little Boy. They were supervised by Harlow W. Russ, an expert on Little Boy who served with Project Alberta on Tinian, and was now leader of the Z-11 Group of the Los Alamos Laboratory's Z Division at Sandia. Gradually, they managed to locate the correct drawings and parts, and figured out how they went together. Eventually, they built six Little Boy assemblies. Although the casings, barrels, and components were tested, no enriched uranium was supplied for the bombs. By early 1947, the problem caused by the Wigner effect was on its way to solution, and the three officers were reassigned."

Only children deny the holocaust. A man points out that the dead of that were 10% of the war, and a fraction of those ground to bloody mush in the hellscape of the Eastern Front as Hitler drove his legions into the heart of the Red Empire. The Jews are almost to be commended for their shameless self-promotion of their suffering, and their ability to turn blood into gold. almost, were the business of it not so tasteless and ugly.

You bring nothing but innuendo and vague descriptions to us.
Present your theory in the light of day and let it stand or fall on its merits. And do not think those of us that doubt you are foolish enough to swallow the metanarrative of the western powers hook, line, and sinker.
Little Boy, the Hiroshima bomb, used 141 lb (64 kg) of uranium with an average enrichment of around 80%, or 112 lb (51 kg) of U-235, just about the bare-metal critical mass. (See Little Boy article for a detailed drawing.) When assembled inside its tamper/reflector of tungsten carbide, the 141 lb (64 kg) was more than twice critical mass. Before the detonation, the uranium-235 was formed into two sub-critical pieces, one of which was later fired down a gun barrel to join the other, starting the nuclear explosion. About 1% of the uranium underwent fission;[11] the remainder, representing most of the entire wartime output of the giant factories at Oak Ridge, scattered uselessly.[12]
