Little Boy was one of the first Nuclear weapons tested on Mankind.
While the dangers and the Engineering behind it were even regretted by the scientist Oppenheimer.
Julius Robert Oppenheimer was born on April 22, 1904.
He worked on the Manhattan Project and was often coined as the father of the Atomic Bomb.
But the interesting part was later in his life, he fought to eliminate the production and development of nuclear weapons, and died at the age of 62 in 1967.

The detonation process of these are overwhelming. The amount of time and brains it took to create is fascinating. How they used radio waves to read barometric pressure, and then activates the firing switch. And how it sets off a charge, it’s so brilliant.

@M0NMCAmateurRadioStation 9 ай бұрын

The 3 green safety plugs were removed and replaced with red arming plugs once over the target area. This armed the weapon. The green plugs blocked the electrical path to the arming circuit, timer, barometric and radar triggers. This was a necessary safety feature as there were fears of possible detonation, either on take off or in flight. The plugs weren't removed on deployment. Great video though of a fascinating part of history.

300 m/s second is a fairly low speed for shooting the uranium rings into the uranium plug (wonder why not shoot the smaller plug into the rings?!). The faster they are shot together, the more complete the fission reaction thus more power yield. I read that only less than 5 percent of the total uranium actually went fissile in Little Boy, the rest was wasted. Fat Man had extremely high speed explosive lenses in the 8K m/second range for the fastest possible implosion.

@@billant2 The target area was surrounded by a neutron reflector. The firing of the bomb enclosed the uranium structure entirely in a reflective cylinder, with the cap being what pushed the hollow rings into the cylinder. Had the Hollow rings been placed there they would've been in chain reaction or dangerously close to such. As such the hollow section had to be what was added later

The “Silverplate” B-29’s also had the aft bomb bay removed and the forward bomb bay length increased (to handle the longer atomic bombs (the very first had the front and rear bomb bays merged)). The forward bomb bay was fitted with Lancaster “Grand Slam” bomb shackles (and dropped “Grand Slams” on practice missions over Japan (along with “Pumpkins” (impact fused non nuclear versions of the Fat Man bomb))). The orange painted pumpkins acted as both practice weapons, blast bombs and security cover for the visually identical Fat Man bombs (yes, bombs plural - 15 were built before they were superseded by the Mk4 replacements in late 1946 (11 by the end of November 1945)).

@buckhorncortez 10 ай бұрын

@@allangibson8494 The only B29 built with a single set of bomb bay doors was made to do aerodynamic development of the "Thin Man" bomb casing. Thin Man was the original gun-type bomb designed for use with plutonium. The Thin Man bomb was 17 feet long which is why the modified B29 was needed. When the first reactor made plutonium became available it had Pu240 in it and a gun design would have caused a fizzle (pre-detonation). When the plutonium bomb design was changed to implosion, the single bomb door was not needed as both Little Boy and Fat Man would fit into the front bomb bay of a B29. The rear bomb bay was then used for carrying additional fuel extending the range of the airplane. None of the Silver Plate bombers used the single-door configuration, they had two sets of bomb bay doors. You can reference both “B29: The Superfortress,” by Carl Berger, and “Atom Bombs: The Top Secret Inside Story of Little Boy and Fat Man,” by John Coster-Mullen for this information.

@allangibson8494 10 ай бұрын

@@buckhorncortez The forward bomb bay on all the Silverplate B-29’s was lengthened and reinforced. The bombing radar was moved slightly aft as a result. You need two side by side to see the difference between the standard and silverplate versions. The aft bomb bay was deleted and, as you noted, used for additional fuel tankage leaving only the forward bomb doors operational. Only the forward bomb bay could be used for bombs after modifications and the aft bomb bay fuel tank had to be carefully managed to maintain weight and balance.

It is important to note, the Little Boy Bomb was never tested like the Fat Man Bomb which used Plutonium 239, whereas Little Boy used Uranium 235. Oppenheimer and his team were so confident in the Little Boy design it was never tested and it really wasn't proven until it was dropped on Hiroshima.

The acknowledged difficulty with the Fat Man was the timing and relative strengths of all the charges for the implosion. For it to work correctly - ie not to end up with the core being spat out - the timing and strength of each charge had to be perfect. The development of all this consumed a lot of time, effort, and expenditure and there were doubts until the very end if it would work. The Trinity test proved that it did. The gun type was much simpler in concept and to manufacture.

All the weapons grade uranium made up to that point was used in the Little Boy. There wasn’t enough to make another bomb until later.

@khb6686 10 ай бұрын

With respect little boy was exponentially less efficient. Also keep in mind that U-238 or plutonium does not naturally occur on earth or anywhere. It has to be made by enriching U-235 to an atomic weight of U-238. So in essence the natural progression to initiate a larger output of energy is implosion. Lucky for the physicists at los alamos someone was working on changing the the shockwaves of conventional explosives from concave to convex and thus changing the process of how they split the atom and more efficiently changed history. A machined hollow sphere of approximately ten pounds of plutonium was compressed by hundreds of pounds of composition b which is now c-4/symtex. And boom. You get a little less than 200k lbs of tnt. What is really interesting is the incorporation of tritium and other elements and stryofoam that Teller figured out would give us the fusion bomb. Which I think Oppenheimer and the physicists at Los Alamos already knew about given the outcome of their math.

@franklinbarrett4630 10 ай бұрын

@@khb6686 A bit of clarification, uranium does occur in nature but most of it is U238 which can’t sustain a chain reaction. So factories at Oak Ridge worked to separate U235 from U238 leaving enriched uranium and depleted uranium.

Parsons didn't pull the arming plugs. Parsons inserted the cordite explosive bags into the bomb. The safing (green plugs) were pulled by Morris Jeppson and replaced with red pull-out plugs. Performed by Captain Deak Parsons Checklist for loading charge in the plane with special breech plug (After all D-3 tests are completed) 1. Check that green plugs are installed. 2. Remove rear plate. 3. Insert breech wrench in breech plug. 4. Unscrew breech plug, place on rubber pad. 5. Insert charge, 4 sections, red ends to breech. 6. Insert breech plug and tighten home. 7. Connect firing line. 8. Install armor plate. 9. Install rear plate. 10. Remove and secure the catwalk and tools. The bomb was fully armed only after the green plugs had been removed and the red plugs inserted, by Electronic Test Officer Morris Jeppson

Great animation! It's amazing to me that they never tested this type of bomb because they didn't have enough enriched Uranium. They just presumed it would work. The trinity test, arguably the first nuclear bomb, used a plutonium/fat man type bomb. The first nuclear reactor was made several years earlier, and a few more were made to produce the plutonium. These reactors heated the Columbia river without producing electricity. It's hard to make a nuclear bomb that doesn't fizzle, blowing itself apart before the chain reaction has a chance to do much damage.

Small error, it is a Superfortress not a Superfortess. I think it said correctly towards the end. Interesting note, the B-29s used were special Superfortresses called "Silver Plate" which were modified to carry the bomb. Also, though not mentioned in the video but is a common mistake made by many, Trinity was not testing the viability of a nuclear bomb. They knew the Uranium Little Boy bomb would work and it was already 8in transit to Tinian before Trinity. Trinity was testing if the implosion plutonium device, Fat Boy, would work.

Pretty much as they taught us in nuclear weapon school. Of course some stuff changed, but gun type weapons were still in the inventory until the early 90s. Later, for artillery rounds, the target rings were replaced by a solid piece, the projectile rings were modified so you could select the yield you wanted. I had an exciting experience when, while building a yield, I lost grip of a target ring (they are super heavy) and it slammed onto another ring. Ooooo, what a flash and spark.

Great animation! Overall very good. Just a couple of possible corrections (according to what I have read in other sources, particularly Richard Rhodes' book The Making of the Atomic Bomb). The barometric switch closed at about 8000 ft (2440m) and brought the Archie radar altimeter units on-line. There were four radar altimeter units, and any two of them sensing the proper altitude for detonation (1900 ft, or 580m) would fire the bomb The polonium initiators were not strictly necessary (the spontaneous fission rate of U-235 should have been sufficient to start the chain reaction when a supercritical mass had been assembled), but Oppenheimer supposedly added them at the last minute to hedge his bets. The B-29s used for the atomic strikes were not standard-issue aircraft, they had been modified to the so-called Silverplate specification which, among other things, removed defensive armament except for the tail guns. But these are minor details in an otherwise excellent presentation.

Shouldn't exist? That's true. Unfortunately, there was little choice in the matter. It wasn't just the US that had a nuclear weapons program in WW2, All the major players had their programs. The Manhattan Project was a collaborative work headed by the US and supported by Great Britian and Canada. Germany was the first nation to start trying to develop an atomic bomb, and was very close to succeeding. The Soviet Union, and Japan were trying to develop atomic weapons. Whoever developed it first would most likely have used it. Either to end the war, or as a last-ditch effort to keep from losing the war. It is a terrible weapon that had no choice but to be developed.

Great animation! You could have explained how those protons ejected during the fissile process had to hit other nuclei to create the chain reaction. One of the problems The Manhattan Project had to solve involved the reduction of free protons unable to hit further nuclei. Also, it would have been informative to mention the 77,000 generations of fission that take place in a super-critical mass, of which only the last 11 are the flash and heat of the expolsive force. Other than these minor comments, a great job! Given that the world is so close to nuclear war at the moment, it would have been beneficial to look at the Japanese survivors and their horrific wounds and illnesses. Please remember that these bombs are minuscule compared to the fusion weapons of today!

Long story short Britain knew of the concentration camps, yet denied their existence when the Soviets found the first one at Dachau, also it was the secret network that informed the Soviets of when and where the Germans and Axis were planning an offensive. Was key in the battle of Kursk. Only successful Axis offensive was when I think Heinz Guderian made a decision without letting Berlin know.

@username1957af 10 ай бұрын

The polonium initiators were used to increase the amount of neutrons available for fission, helping to ensure a chain reaction.

@buckhorncortez 10 ай бұрын

The initiators were made of polonium-210 and beryllium-9. Polonium emits a constant stream of alpha particles. When an alpha particle strikes a beryllium atom it causes the beryllium to emit a neutron. The initiator for the two atomic bombs was called "The Urchin." It had a small pellet of beryllium in the center, surrounded by a shell of layers of polonium and beryllium. The beryllium was shielded from the polonium by either nickel or gold plating or foils. When the initiator was crushed it mixed the beryllium with the polonium causing a shower of neutrons to start the chain reaction. This is important as the fission reaction automatically stops when it reaches 1.12 times the radius of the mass when the reaction started. The more U235 atoms that fission simultaneously when the reaction begins, the larger the final yield.

@JackHudler 10 ай бұрын

@@Aitelly it was very much necessary. The gun bombs had a major weakness. Premature initiation. The chain reaction only takes about 100 ns to initiate. Once started the projectile will never reach the Polonium, thus the bomb yield will be low (dirty bomb), and Hiroshima would probably be uninhabitable today. So they made the decision lower the mass of the leading rings, save one. Thus they needed to make sure to artificially stimulate the initiation to reaction with Polonium-210. The bomb would work without the Polonium, but they built-in safeguards to make sure.

1) The B-29s used for dropping atomic bombs were modified. All the automatic gun turrets - except the rear gun and gunner- were removed to save weight. 2) The plane had to make a sharply banked turn after releasing the bomb to escape the blast effect. 3) You need to state that the hard IMPACT of the uranium fired by the gun charge into the polonium igniters sets off the chain reaction.

@Gallagherfreak100 5 ай бұрын

I read somewhere the gun type U235 bomb was so inefficient, that despite the bomb containing approx 135 lbs of U235, only a piece about the size of a dime actually underwent fission. The rest of the U235 was simply blown apart. It took an enrichment plant located in Oak Ridge, TN about three years to produce the U235 used in the little boy bomb and at certain points, was consuming about 10% of the all the electric power available in the U.S. A rather inefficient use of resources.
