King's Nuclear Weapons Fascinating Facts Information


Updated: 7 April 2015

Since 1945 there have been more than 2,000 test nuclear explosions
conducted throughout the world.

As of 28 Aug 2014, there are approximately 16,300 total nuclear weapons.

The United States has approximately 7,300 warheads

    Russia - 8,000
    China - 250
    France - 300
    U.K. - 225.

Isreal, Pakistan, India and North Korea are not signatories
(have nuclear weapons, but not part of the) Nuclear Non-Proliferation Treaty.
Treaty members agree to limit the spread of nuclear weapons.
Their warhead arsonel is as follows:

    Isreal approximately 80 warheads
    Pakistan - 120
    India - 110
    North Korea possibly 6 to 8.

The bomb dropped on Hiroshima, Japan, in 1945 was an atomic bomb which killed over 140,000 people,
and had the power of 15-Kilotons.
Atomic bombs use nuclear fission, or the splitting of an atom, to achieve an enormous explosion.

A common hydrogen bomb, which uses nuclear fusion, or the fusing of atoms, has the power of up to 10-Megatons.
To achieve fusion, an atomic bomb is at the center of a common Hydrogen bomb, creating immense heat used to fuse the atoms.

All the explosions in World War II combined totalled "only" 2-Megatons
or just 20% of the power of just one common Hydrogen bomb.

A 10-Kiloton nuclear device has the power of 10,000 tons of TNT.
To haul that much explosives you would need a cargo train of 100 cars long!

However, a nuclear bomb could easily fit into the back of a truck.


    * August 6, 1945: 15-Kiloton Uranium bomb dropped on Hiroshima, Japan.

    * August 9, 1945: 21-Kiloton Plutonium bomb dropped on Nagasaki, Japan.

    * October 30, 1961: Soviet Union detonates a 50-Megaton Uranimu bomb.
    This bomb nicknamed the "Tsar Bomba" or "King of Bombs"
    would be the largest nuclear weapon ever detonated.
    The detonation occurred over the Arctic island of Novaya Zemlya.

    Tzar Bomba Mushroom Cloud

    The explosive inpact of this device was 6,500 times more deadly than the bomb dropped on Hiroshima.
    The bomb proved that the delivery of nuclear weapons by long range aircraft was ineffient in time war.
    As a result Intercontinential Ballistic Missiles were created.

    The bomb was never intended for actual use. Rather it was used to intimidate the United States.
    Tsar Bomba was dropped via parachute from an altitude of 4,200 meters, or 2.6 miles,
    and the resulting fireball nearly reached the height of the release plane.
    Light from the explosion was visible from 1000 km, or 621 miles, away.
    The bomb was so hot it induced 3rd degree burns at 100 km, or 62 miles, away.


Suitcase Bomb; 0.1-Kiloton

    Approximate blast at 100 feet above surface:

    - Most structures destroyed out to 0.15 miles of the blast area.
    - Approxmiately 50% dead from radiation within one month's time out to 0.3 miles.
    - Massive fires out to 0.07 miles.

Atomic Bomb; 15-Kiloton bomb.

    Approxmiating blast at 550 feet above the surface:

    - Most structures destroyed out to 0.8 miles of the blast area.
    - Approximately 50% dead from radiation within one month's time out to 0.8 miles.
    - Massive fires out to 0.9 miles. Possible fires out to 1.2 miles.

Hydrogen Bomb; 300-Kilotons

    Approxmiate blast at 1,500 feet above the surface:

    - Most structures destroyed out to 2.2 miles from the blast area.
    - Approxmiately 50% dead from radiation within 1.3 miles in one month's time.
    - Massive fires out to 3.5 miles; Possible fires out to 4.6 miles from blast area.
