The True Scale of Nuclear Weapons

The True Scale of Nuclear Weapons

Sounds horrifying, right? Well, we’re just getting started. Today we’re comparing the scale of six of the world’s most destructive nuclear bombs, Including one so devastating it was deemed too risky to use. Brace yourself - it’s about to get loud.

00:00 Hiroshima
00:52 North Korean 2017 Nuclear Test
01:45 B-83
02:52 Castle Bravo
03:54 Tsar Bomba 50
04:55 Tsar Bomba 100

0.539 -> today we're comparing the scale of six
3 -> of the world's most destructive nuclear
5.339 -> bombs including one so devastating it
8.46 -> was deemed too risky to use brace
11.16 -> yourself
12.179 -> it's about to get loud
15.78 -> starting off we have the 15 kiloton bomb
19.32 -> that the U.S dropped on Hiroshima in
21.9 -> 1945.
24.119 -> little boy caused the deaths of around
26.279 -> 80 000 people and exposed tens of
29.4 -> thousands more to high levels of
31.26 -> radiation
32.7 -> it gets worse the temperature near the
35.52 -> blast site in Hiroshima reached 300 000
38.7 -> degrees Celsius
40.079 -> for perspective that's about 300 times
43.079 -> hotter than the temperature bodies are
44.94 -> cremated at sounds horrifying right
48.899 -> well we're just getting started
52.739 -> in 2017 North Korea detonated a nuclear
56.219 -> bomb 16 times more powerful than the one
59.1 -> that devastated Hiroshima the nuke is
61.559 -> said to have weighed in around 250
63.78 -> kilotons ish
67.14 -> yeah here's where things get a little
69.06 -> murky researchers aren't exactly sure
71.7 -> what the power of the bomb was and North
73.86 -> Korea isn't spilling the tea but they
76.08 -> estimate it was between 148 to 328
79.619 -> kilotons
81 -> on the other hand the U.S Intel
83.34 -> Community estimated it was 140 kilotons
87 -> one thing is for sure though
89.159 -> it was felt all around the world
92.1 -> seriously this bomb was so intense it
94.68 -> caused an earthquake with a magnitude of
96.78 -> about 6.3 the sound waves from the
99.9 -> explosion were so powerful they were
101.64 -> picked up by seismometers worldwide
104.64 -> up next is one of the most powerful
106.439 -> bombs in the US's Arsenal the b-83
110.939 -> this nuke has a yield of around 1.2
113.52 -> megatons of TNT but what does that mean
116.159 -> exactly
117.299 -> well let's break it down you don't need
120.42 -> to be a nuclear physicist to know you
122.399 -> want to be far away from one of these
126.42 -> once it hits it'll create blast waves
128.88 -> with a force of about 180 metric tons
131.76 -> and wind speeds of 255 kilometers an
135.3 -> hour within a six kilometer radius
138.78 -> if you were within about a 21 kilometer
141.42 -> radius you'd experience flash blindness
143.879 -> within an eight kilometer Circle you'd
146.22 -> get third degree burns you know where
148.02 -> your body tissue gets blistered and then
149.879 -> destroyed and if you're within a one
151.92 -> kilometer radius you'll be hit by blast
153.9 -> waves with 720 metric tons of force and
157.2 -> Winds of 756 kilometers an hour
159.78 -> medically speaking it it's gonna suck
163.319 -> there are about 650 b83s in active
167.4 -> service so that's comforting
172.739 -> next up Castle Bravo the biggest nuclear
176.519 -> bomb ever tested by the US it packed a
179.22 -> punch of around 15 megatons and caused
182.099 -> an explosion two and a half times more
184.14 -> devastating than researchers anticipated
187.519 -> and this was obviously a problem yeah
191.04 -> this bomb was one thousand times more
193.44 -> powerful than the one dropped on
194.879 -> Hiroshima
197.519 -> radioactive debris spread across 18
200.7 -> 000 square kilometers
203.099 -> contaminating people on nearby islands
205.44 -> and even on a Japanese fishing trawler
208.739 -> this was dubbed the worst radiological
211.2 -> disaster in U.S history and it caused a
214.2 -> massive uproar against nuclear testing
218.099 -> understandable when you see this
219.84 -> staggering 7.2 kilometer wide 39.6
223.26 -> kilometer High mushroom cloud
225.959 -> oh and it created a crater on the ocean
228.12 -> floor nearly 2 000 meters wide and 76
231.299 -> meters deep
232.56 -> that's huge but the next two on our list
235.379 -> are even bigger
238.08 -> the Tsar Bomba 50 was not your average
240.659 -> bomb it was a hydrogen bomb and the most
243.299 -> powerful one ever tested it had a yield
245.879 -> of about 50 megatons
249.959 -> in 1961 the USSR detonated it on a small
254.28 -> Arctic Island creating a shock wave that
256.799 -> turned the island into a flat skating
259.32 -> rink
261.419 -> the bomb was commissioned by Nikita
263.639 -> Khrushchev and weighed 27 tons and
266.639 -> required an aerial bomber to transport
268.62 -> it to the Arctic
270.479 -> the detonation was so powerful that it
273 -> knocked the bomber down 900 meters
275.58 -> before the pilot could course correct
278.88 -> it's not hard to see why a bomb with
281.1 -> this kind of power was never made again
284.1 -> but that doesn't mean the USSR didn't
286.5 -> want to
287.82 -> okay so Khrushchev may have commissioned
290.34 -> the Tsar Bomba 50 but did you know he
292.919 -> originally wanted a 100 Megaton nuclear
296.4 -> bomb
297.38 -> yeah plus 50 baby
301.5 -> the plan was to create a three-layered
304.08 -> bomb with uranium layers separating each
306.54 -> stage but testing the bomb was too oh
309.66 -> what's the word risky
312.6 -> even Soviet physicists were worried the
315.06 -> bomb would cover the whole north of the
316.86 -> USSR with a massive cloud of radioactive
319.56 -> fallout
323.16 -> and if that wasn't enough the bomb was
325.979 -> too heavy so heavy it couldn't be placed
328.68 -> on a missile or strapped to any plane
330.96 -> and even if it could have it would have
333.06 -> taken a crazy amount of fuel to get to
335.34 -> the Target and fly away safely making it
338.28 -> a one-way trip for any pilot
343.38 -> how long do you have to wait inside
344.82 -> while hiding from nuclear fallout find
347.22 -> out here on how to survive
