| Nuclear Bomb - First H Bomb test |
 |
Ivy Mike was the first H Bomb test, it was
exploded at 7.15 am local time on November 1st
1952. The mushroom cloud was 8 miles across and 27
miles high. The canopy was 100 miles wide.
Radioactive mud fell out of the sky followed by
heavy rain. 80 million tons of earth was
vaporised. Mike was the first ever megaton yeild
explosion.

The Tsar Bomba
_______________
October 30th 1961 - The Tsar Bomba, King of the
Bombs, Царь-бомба or Big Ivan.
This footage is courtesy of the documentary
"Trinity and Beyond", directed by Peter Kuran, and
other footage is courtesy of the Discovery
channel. The original footage was from
declassified Soviet Archives. The music used is
from The Planets Suite composed by Gustav Holst.
The movement is 'Mars: the Bringer of War'
Before I get into the details of the test, I want
to clear up something very important. The title of
this video is "Tsar Bomba - King of the Bombs -
57,000,000 Tonnes of TNT". Understand now that
this test wasn't the result of a detonation of
57,000,000 Tonnes of TNT, but rather the nuclear
yield EQUIVALENT of a detonation of 57,000,000
Tonnes of TNT. The weight of the device was 27
tonnes. And coincedentaly, one tonne is taken as a
metric tonne, or 1000 kilograms - (2200lbs). All
units used in physics are metric. The reason the
yield equivalent system is used is because the
energy released from the explosion of a set amount
of TNT is a constant.
The bomb was designed as a 100 Megaton device, not
a 50 Megaton device. This was due to its 3 stage
design: fission-fusion-fission. There is fission
initiator that when detonated, begins a fusion
reaction. Then there is a further fission
detonation of a Uranium tamper which boosts the
yield by 50 Megatons. For the test, the Tsar had
its Uranium tamper replaced with lead to reduce
the maximum yield by half (To 50 Megatons).
The blast yield was equal to that of a blast of
57,000,000 Tonnes of TNT....or to put that into
context: The weight of 270 Empire State Buildings
worth of TNT. This makes the Tsar the most
powerful nuclear device ever detonated in history.
Think of the destruction at Hiroshima. The Tsar
was 3800 times more powerful than Hiroshima.
The bomb's weight was 27 tonnes, and its
dimensions were: 8 meters (26ft) in length, and 2
meters (6.5ft) in diameter.
It was air-dropped, from a modified Tupolev Tu-95
Bear, and it used a nylon parachute to slow its
decent to give the crew time to escape.
The bomb was dropped from an altitude of 34,500
feet AGL (10,500 meters), and it detonated a
little over three minutes later at an altitude of
13,100 feet AGL (4,000 meters). In this time: The
Tu-95, travelling at a ground speed of 480kts
(552mph, 864kph), travelled into the safe zone
(about 45km from ground zero) and was therefore
79km away from the blast.
When the bomb detonated, immediately the
temperature directly below and surrounding the
detonation would have risen to millions of
degrees. The pressure below the blast was 300
pounds per square inch, over three times the
pressure in a car tyre. The light energy released
was so powerful that it was visible even at 1000km
(621 miles), with cloudy skies. The shockwave was
powerful enough to break windows at even up to 900
kilometres (560 miles) from the blast. The
shockwave was recorded orbiting the earth 3 times.
The mushroom cloud rose to an altitude of 64,000
meters (210,000 feet) before levelling out. The
thermal energy from the blast was powerful that it
could cause 3rd degree burns to a human standing
100 km (62 miles) away from the blast.
The radius of the fireball was 2.3 kilometres (1.4
miles). The blast radius (area in which total
destruction ensured) was 13km (8 miles).
The most important thing to note is that this bomb
was designed as a 100 Megaton device (Yield
equivalent of 0.1 trillion tonnes of TNT). If
detonated, everything within a 48 kilometer (30
mile) diameter would be vaporised. Everything
within a 195 kilometer (120 mile) diameter would
be incinerated in a fireball. This would ensure
total destruction of a large city like New York,
Paris or London, as well as devastation on its
outskirts.

about the test history.
