A test...

to measure and calibrate
the power of a nuclear weapon ever tested.

Two months later...

Man releases the destructive power
a demon imprisoned

into the very fabric of matter,

and plunge the world
in the atomic age.

Over the next 20 years,

power tests

will maintain the fascination of the world
for these events surrounded by secrecy.

TRUBULENCES IN EUROPE!

Hitler invaded Austria!

March 13, 1938.

Hitler invaded Austria.

3rd Reich begins to deploy
its military power.

Later that year,
German scientists

discover fission
of the uranium nucleus

What brings the 3rd Reich
a step

the discovery of the secret
of the atomic bomb.

FEAR!

Fear of German research

stimulates activities to
É United States and England.

The fear that German scientists

could produce weapons
high destructive power.

In autumn 1939,
Dr. Albert Einstein

wrote his famous letter
President Roosevelt,

explaining the urgency of working
in the fission of uranium.

Roosevelt, a man of action,
responded quickly,

and creates an advisory committee
of uranium.

GERMANY INVADES POLAND!

German forces invaded Poland

dragging European nations
in the second world war.

ING DISTRICT É NIEURIE
OF MANHATTAN

A new branch of the Corps of Engineers
was created to oversee the work

on military use of uranium.

Major General L.R. Growe,
the man in charge of the Pentagon,

was appointed head
project.

December 2, 1942, the first reactor
Autonomous chain reaction

has been successfully exploited by Enrico Fermi.

The success of Fermi generates
great efforts

the government
and the private sector,

leading to the creation of huge factories,
for the separation of uranium

in the town of Oakridge, Tennessee,

and for the production of plutonium
Hanford, Washington

on the banks
Columbia River.

Through this effort was forged great
the necessary hardware

to create an atomic bomb.

The first atomic bomb
was built at Los Alamos,

a secret laboratory
New Mexico

When Dr. Oppenheimer J.R.
arrived to take command

he surrounded himself with an incredible range
stars of the scientific world.

Los Alamos was born on design
the bomb and resolution

many theoretical problems.

Many questions remain unanswered, however.

What are the secrets of this new
form of power and destruction?

Knowledge and Information
all aspects of this new weapon

are essential,

and can not be discovered that
by further testing.

I had a good friend, a Hungarian
10 years older than me, Leo Szilard.

He had a very independent-minded

and a large capacity
foreshadow what would happen.

He saw the years ahead

the importance that the explosives
Nuclear would take.

He was a friend of mine, and I helped him.

For example, I took it to
an important interview with Einstein

where Einstein wrote this
famous letter to Roosevelt.

The letter that started it all.

I myself was interested in
Theoretical Physics

atoms, molecular vibrations,
and knowledge of molarity.

I did not want to do.
But then...

Hitler had not only swallowed
half of Poland,

he had also invaded the West.

Two days later, there was
an invitation to a Pan-American Congress

in which Roosevelt, that I had never
seen before, was to speak.

He made a memorable speech,

about how the world is
really in danger because of Hitler.

He said in part, to the point
highlight of the speech:

"You scientists, will be blamed
for the arms to be used"

but I tell you,

"if you do not work on these weapons,
world freedom will be lost."

You know, I felt
Roosevelt spoke to me.

I was there when
The letter was signed

one that stirred up the interest
in nuclear power

He was convinced that
was nuclear

Of the 2,000 scientists who were there,
I felt it spoke to me.

Of course it was not that...

But for this speech
twenty minutes

I made my decision.

I continued to prefer
work in science 'pure',

but this must be done.

Since this must be done

and that I could contribute,
I did,

and I have never regretted
to have done.

The uranium bomb,
called "Little Boy"

had a simple design.

And scientists were convinced
fonctionnerai it without testing.

"Fat Man", or the implosion bomb,
was a more efficient design

which used plutonium
rather than uranium.

In the center of the bomb,
there was a detonator

surrounded by a sphere of plutonium.

This sphere was encapsulated

in a series of lenses highly
explosive placed symmetrically,

creating an implosion
compressing the sphere of plutonium

on itself until it
reaches critical mass.

The explosion brought immediately
temperature to 10 million degrees,

releasing a force of one half
million pounds of pressure

vaporizing the tower and all
desert living within 800m.

The intensity of the light
was sufficient

to cause temporary blindness
an observer at 16 km distance.

With a score of 200 times more potent
the test with 100 tons of TNT,

the fireball created a crater
about 800 m in diameter.

And melted the desert sand

always contain traces of radioactivity
50 years later.

May 8, 1945,

Germany surrendered to Allied forces,
This puts an end to the war in Europe.

intelligence sources as
command of General Groves concluded

that Germany had not developed
the atomic bomb.

However, the war continued

Pearl Harbor forced the entry

For three years, gaining ground

to launch the first bombs
on Hiroshima and Nagasaki atomic

VICTORY!
Japan surrenders

The uranium bomb,
called "Little Boy"

exploded over Hiroshima
at an altitude of 250 meters.

The altitude to achieve
maximum blast.

Three days later,
the implosion bomb "Fat Man"

exploded over Nagasaki.

In Hiroshima 70,000 people
were killed or missing.

On its 90,000 buildings,
more than 60,000 were demolished.

The implosion bomb dropped on
Nagasaki took the lives of 42,000 people,

and injured 40,000 others.

It destroyed 39% of
buildings in the city.

With a yield of 20 kilotons,
similar to that of Trinity,

this weapon will be considered
as a normal bomb,

and serve as a model for
future nuclear weapons.

- 11 months later -

But our main objectives
are the warships.

We try to first learn

What types of ships, training
tactical and strategic needs

of our own naval forces
who survive best

an attack with nuclear weapons
in case we need to cope.

OPERATION CROSSROADS

11 months after the bombing
Hiroshima and Nagasaki,

the operation was conducted Crossroads
on Bikini Atoll

4000km to the west of Hawaii.

The aim of the operation

was to test the effects of weapons
nuclear using two devices

similar in design to those
Trinity and Nagasaki.

Their code names:
"Able" and "Baker".

Able to be launched
from a B-29,

while Baker was detonated
to 30 m below the water surface.

The fleet consisted of target
185 Japanese ships

German and American.

From small amphibious craft
to battleships and aircraft carriers.

The bomb will not start a
chain reaction in water,

converting it all to gas

and to ensure that all vessels,
of all the oceans, fall to the bottom.

It will not explode
the bottom of the ocean

and bring down all the water
a hole in

It will not destroy gravity.

I am not an "Atomic Playboy"
as one of my critics called me,

that these bombs would explode
to satisfy my personal whim.

Animals, plants, and similar agents
biological warfare were assembled

to study the effects of heat,
blast and radiation.

The bomb missed its target
of almost 750 meters

The explosion sent five ships,
including two destroyers,

the lake bottom of Bikini.

All vessels within 800m
were severely damaged.

But the damage was
far from those caused

by the underwater explosion
that followed, called Baker.

fire.

Baker was an underwater explosion
Navy of the same device,

and caused much more damage
the fleet to 70 vessels.

For example, on the USS Saratoga

the shockwave submarine tore
the bottom of the hull of the boat.

Saratoga sank still lies
at the bottom of the sea from Bikini.

I flew several times
the site and on a clear,

if the water is calm,
you can still see the Saratoga.

The area around
the explosion of Baker

had become highly radioactive,

and could not be
approached for some time.

This effect was not expected,

and led to the decision
President Truman

to cancel a third nuclear test
deep called "Charlie."

Here the city of Los Alamos,
to 1500 meters.

The Atomic City .

is a modern city
created by É United States

as a research center
and development of nuclear weapons.

We are talking about a region
remote and primitive,

men must leave their homes
laboratories and their É States,

for a term which may
reach for months.

Since 1943, when
Los Alamos was founded,

these men left
É the continental limits of the United States

to test weapons
they have created.

Two years after
Operation Crossroads,

President Truman authorized

to conduct the operation Sandstone.

While the goal of Crossroads

was to test the effect
nuclear weapons,

Sandstone objective was to test
design new weapons.

Plans for these weapons were
initiated several years earlier

when researchers from Trinity

have developed other models
experimental atomic weapons,

but were not sure of their success.

A joint working group was created
to go back into the peaceful,

and obtain the island of Enewetak,
300 km west of Bikini,

Crossroads which had taken place.

In early November, the first
Construction crews arrived

to remove all the vegetation of the island,

clean the area and dump
tonnes of asphalt for roads.

In six months, the team built
temporary housing

for many scientists and military
necessary for the operation Sandstone.

Perched on steel towers
60 meters high,

the three devices used to Sandstone
employed a new technology

to double the explosive power
of the bomb

using the same amount of
plutonium spent in Nagasaki.

This technology meets the requirements
Department of Defense

create more effective bombs

and increase the capacity of
store nuclear weapons.

Radio controlled tanks,
guided by helicopter

recovered samples
fission near "ground zero",

for measuring the intensity of
neutrons and gamma rays.

Radiochemical analysis
pulverized coral sand

revealed the secrets
the nuclear reaction,

and helped to determine the effectiveness of
bombs of new design.

The results of Sandstone affectèrent
the design of future nuclear weapons,

making the components 'Mark-3', used
for the production of Fat Man, obsolete.

Designs 'Mark-4' and 'Mark-5'

led to better performance and a
lighter weight for nuclear weapons.

The division of the laboratory Z
Los Alamos National

moved to the base has í Sand,

located in Albuquerque, New Mexico,
near Kirtland Air Force Base.

The main objective of the Sandia Base

was the study and production of nuclear weapons
"Mobile" designed at Los Alamos.

in October 1949,

Western Electric contracted with
The Committee on Atomic Energy,

agreement "no taxes, no profit"
to form the Sandia Corporation

who took control
the basis of Los Alamos.

Sandia has led to techniques
production lines

and mass production
nuclear weapons,

to increase the supply of arms
tactical and strategic nation.

After returning from Bikini,
in public statements,

interviews and published articles,
Admiral Blandey

made important recommendations
on atomic bombs.

It is essential that no other nation
takes the ascendancy over the United States É

in the development, manufacture and
the use of tactical nuclear weapons.

"TRUMAN SAYS RUSSIAN
HAVE A BOMB"

"THE L É legislator TOLD OF SECRETS
AMERICAN FLIGHT É É AID S S HAVE THE RUSSIANS"

On 29 August 1949, the Russians did
exploded their first atomic bomb.

This event,
which took place five years earlier

than anyone in the west
have been expected,

was largely responsible
a man, Klaus Fuchs.

Fuchs, a physicist at Los Alamos,
spent blueprints

the design of
Trinity to the Russians.

With the emergence of the USSR
as a nuclear rival in 1949,

É the United States were convinced
have good reasons

increase their programs
nuclear testing.

It was very expensive and it
involved a lot of logistics

perform operations
in the Pacific.

In this and in January 1951, the United States É
inaugurated the test area of?? Nevada,

we now call
"The Nevada Test Site"

which is located approximately 100 km
north of Las Vegas.

Before you can test the
Weapons of Operation Greenhouse,

the operation was performed Ranger

during which five
new types of nuclear weapons

were launched on
new test area.

First explosion É to United States
from Trinity.

With the confidence of having
The new weapons in hand,

Operation Greenhouse was
conducted in Spring 1951.

4 launches took place
Greenhouse during the operation.

One of them, "Easy"

a structural test was controlled
by the Ministry of Defence.

A nuclear device of 47
kilotonnes was placed on a tower,

which blew many buildings,
that had been built

to test the survivability
in a nuclear environment.

Test structural effects.

The fourth test of the operation
Greenhouse testing was "Item".

A trial approximately 45.5 kilotonnes

in which tritium was burned
in the center of the nuclear explosion.

And this process, placing the center of tritium
of nuclear weapons is called "Boosting".

We increased the yield
from 20 to 45.5 kilotonnes,

more than double,
through this process.

A very important feature
to increase the storage capacity

nuclear weapons of É United States
at that time.

First test of the principle "Boosting"

Another event of Greenhouse
was the event called "George."

George was a huge weapon
of 225 kilotons

which was used to burn
a capsule deuterium.

This was the first experience with weapon
Thermonuclear we conducted.

HYDROGEN BOMB À È DO

Several people have mentioned, we
have discussed many times.

À the end of the war, most
people wanted to stop, but not me.

Because there was a more

above all.

And I must say that
it has pleased Trueman,

À about 40 km of the islands
Parry and Enewetak.

The two islands at the base of this
test area in the atolls.

The three islands that make up
the test site

have been connected by bridges,

constructed to facilitate
the displacement of an island to each other,

and to serve as a platform
for some of the instruments.

On the island "Mike" was the cab,
or the building housing the device.

The device "Mike" was called
the "wet bomb"

because he used
liquid hydrogen isotopes

to create the thermonuclear reaction.

This made the device
very impressive,

it weighed 62 tons which made
impractical as throwing weapon.

A wood tube

THE BATTLEFIELD AREA NUCL É

In the spring of 1953,
Commission for Nuclear Energy

and the Department of Defense has made
11 nuclear tests in Nevada

under the code name
"Upshot-Knothole."

The Upshot-Knothole objective was to
test new nuclear weapons,

improve tactics of combat,

and study the needs of defense
civil case of Soviet attack.

The first event, called "Encore",
was a 27 kiloton weapon

launched from an aircraft and
landed at an altitude of approximately 850m

over a wide line
deflagration.

The second explosion of the Ministry
of Defense, called "Grable"

exploded in the same region,

and was launched by the new
cannon artillery of the army.

A 280mm projectile was launched
and exploded in the same area

with a power of about 15 kilotons,
at an altitude of approximately 150 meters.

The least powerful,
15 kilotons to 150 meters,

produced a much greater destruction

that the higher power device,
Still, 27 kilotonnes of 850m.

This is because less energy
low-lying

produces a shock wave abnormal
we now call "Pre Crusher"

that generates very violent
wind dynamic

generating for the target
very serious damage.

For example, a Jeep on the ground, had
not damaged especially with Encore,

but with Grable and
effect "Pre Crusher"

the same jeep was
broken into pieces,

and thrown out on
a distance of 150 meters.

There are many other features
these two launches,

but they opened a whole new view

on how to use weapons
nuclear in a combat situation.

THE SAFETY S É É IS COMMON SENSE!

the desert floor in a ball.

As new models of weapons
continued to be tested,

the Ministry of Defence
tests used

to accelerate the military training
in the nuclear battlefield,

while pursuing the study of
effects of nuclear explosions.

The 21st test conducted during the operation
Plumbbob the event was "Rainier."

It was the first explosion completely
led underground by É United States.

The device exploded three kilotons
240m to under Mount Rainier,

spraying of the powder of rock
within 30 meters.

This technology will be of great importance
after the Treaty of restriction tests

banning all nuclear tests,
except underground

and to hide future experiments
from prying eyes.

During Operation Hardtack, the United States É
detonated 35 nuclear devices,

as well as in all previous tests
the Pacific.

So far, nuclear testing
were seen largely

practice as intimidation,

increasing international tensions

that could lead
a nuclear war.

Against the increasing pressure,

the U.S. Government believed
although the weapons are essential,

and they are the only counterweight to
increasing the number of Soviet soldiers.

The Russians, having developed and finalized
a series of atmospheric tests,

pretended to surrender
tests, knowing full well

É the United States had undertaken
a major operation.

Operations were conducted
Bikini and Enewetak in as before.

And a new site was created
Hardtrack for the operation,

Johnston Island.

During testing, one of the events
significant event was the Cactus.

It was a small device
18 kilotonnes of which produced

a crater about 42m wide
and 11m deep.

Many years later, in 1980,
all debris from the fission

and radioactive materials that
were in the Enewetak Atoll

were collected and disposed
in the crater of the bomb Cactus.

Then we placed a concrete dome
on the crater

to maintain and stabilize
radioactive materials.

A year before Hardtack,

the Soviets launched a small
satellite named "Sputnik-1."

Concerned about the superiority
Soviet missiles,

É the United States have made
their first two shots

missiles at high altitudes,

known under the names "Teac" and "Orange".

Nuclear weapons from Teac and Orange

were carried into space
by a Redstone rocket,

developed by Wernher Von Braun.

Von Braun and his team
have developed

the V2 rocket for Germany
during World War II.

The Redstone was considered
an extension of the technology

the Second World War,

and was limited in scope.

Using liquid oxygen
as fuel,

Redstone propelled its nuclear charge
in the upper atmosphere of Earth,

and released for firing.

Teac, with a power
of 3.8 megatonnes

exploded about 80 km
of the surface of the Earth.

The explosion created a violent disturbance
magnetic in the atmosphere

called EMP or electromagnetic pulse.

This silenced the
radios to nearly 8 hours,

And damaged electrical circuits
from Hawaii to New Zealand.

Immediately after the events

É the United States led
"Operation Argus".

Three tests of missiles with warheads
from 1 kiloton in the South Atlantic.

The experiment sought Argus

IVAN (The Monstrous Bomb)
57 Megatons

For two years, a moratorium
difficult on nuclear testing

remains between the United States É
and the Soviet Union.

In secret, the Soviets
began to design

new weapons of mass destruction.

Including a hydrogen bomb
of 57 megatons,

the largest nuclear weapon ever created.

This monstrous bomb
was a smaller version

a model of 100 megatons,

and could be transported
and launched from an aircraft.

While we sit here,
Khrushchev detonated his bomb giant

cynically ignoring the Organization
United Nations.

U.S. to the UN (1961 - 1965)

By this act, the Soviet Union
added insult to injury

they broke the moratorium
on nuclear weapons testing

they raised the air pollution
to new levels,

they started a new race,
for more deadly weapons.

They ignored calls

and all peace-loving peoples.

They have presented no
justification

They remained insensitive

The Delegation of the United States É
deeply regrets

contempt of this
world opinion.

And we think that following these
discouraging events,

other delegations should
express their views

on these new
shocking and disturbing.

Because today, Mr. President,
the world has taken a big step backwards,

into anarchy and disaster.

The Russians had broken
a voluntary moratorium.

É the United States responded quickly

by a wide range of weapons testing
in retaliation for a large scale.

The tension rises when near
100 nuclear tests were conducted

between the test area in Nevada
and the Pacific Ocean,

under the code names Nougat,
Storax and Dominic.
