New Mexico, Arizona, Utah, and Nevada are where much of the
design and testing of nuclear weapons took place, and continues to take
place today. Sandia labs are nearby. Devices were designed, constructed,
and tested in New Mexico, using materials produced in Washington State,
and Arkansas. Much of the basic research had been done in Chicago, where
the world's first atomic pile had been induced into the first sustained
nuclear chain reaction. Since the 9/11 attacks, and with the increased tension
in the world, it is now rather difficult to visit Sandia, so it is just as
well that the museum was relocated. It's new home is in what I call Museum
Square. Just down the block from here, is the New Mexico Museum of Natural
Science, while across the street is the art museum. Old Town, and the Old
Town Plaza are nearby, while Route 66, and downtown are just a short drive
away. This is a fascinating, and somewhat awe inspiring thing to see. What
is most surprising is how small, and normal so many of the nuclear devices
appear. It is hard to relate these seemingly innocuous bits of human fabrication,
with the terror, and power they wield.

Above: The casing to a Fat Man type nuclear bomb, like the one dropped on Nagasaki Power was in the range of 20kt. This is a plutonium bomb, using explosive lenses, and is the route taken for most of today's nuclear weaponry. Below: The Little Boy Bomb casing. This is a uranium bomb, and is a gun type of weapon. Though uranium weapons are sort of the back water of nuclear weaponry, a resurgence may be coming. Though uranium based weapons are heavier, for their yields, they require less maintenance, and can be stored much longer without degradation. This 13kt bomb was dropped on Hiroshima. |

A fellow visitor gives some indication
of the size of these early bombs. If you want the numbers, they are: Little Boy Width 28 in. Length 120 in. Weight 8,900 lb. 13 kt Fat Man Width 60.25 in. Length 128 in. Weight 10,300 lb 20 kt |

Operation Castle was a groundbreaking series of nuclear
tests, resulting in the introduction of an entirely new generation of thermonuclear
weapons. The tests proved far more successful than than planned, with tests
doubling, and even tripling expected output. this caused some participants
to be exposed to excessive levels of radiation, and the evacuation of several
islands. Participants received this acknowledgment certificate. More details

In 1966, a B-52 carrying four B28RI nuclear bombs, exploded.
Two of the bombs also exploded; but because they had not been armed, this
was only a conventional explosion, with no nuclear reactions taking place.
Still, the explosion did scatter nuclear materials from their cores, around
the countryside. The material was scooped up, and disposed of; but the
area is still considered too radioactive for housing or agriculture. |

The other two nuclear bombs, landed unexploded. One in
the Mediterranean, and one on land. Both were recovered. These are the
casings of those bombs. |

The orbital stage of an ICBM, showing the multiple warheads.
The conical MIRVs each contain a warhead, or a series of decoys. |

This is the Arming, fusing, and firing system of a modern
nuclear warhead. |
|
This is the casing for the currently deployed B-83 strategic
nuclear bomb. It has a yield of 1.2 megatons, and is the largest bomb that
the U.S, has currently deployed, though larger weapons are stockpiled..

A look inside of a nuclear warhead. This
is a schematic of one of today's cutting edge weapons. Putting this diagram
on the web, a decade or so ago, would have gotten me thrown into federal
prison. Today, thanks to bill clinton, this has all been declassified,
and given to our rivals and enemies. It is the result of fifty years of
research, and had formerly given us something like a twenty year technology
lead on any other nuclear power. One traitor in public office can do irreparable
damage to national security. |
|
This is me, in October of 2006, standing next to the casings
of the W70, and W80 nuclear warheads, to give an indication of their size.
These little warheads are 15 - 20 times as powerful as the comparatively
gigantic Fat Man type of warhead shown above. Before the clinton betrayal,
no other nation could make such powerful warheads so small. Now the techniques
are public knowledge. |

A number of displays, demonstrating the tools and people
who developed these bombs, and the advances which permitted them to grow
smaller, even as their power was greatly increased. |

This is the mk-7 tactical nuclear bomb, also know as the
Thor. The yield on this 1700 pound bomb was 60 kt. It measured 30" x 183"
. 1800 were produced, making it one of the major nuclear weapons of the
early Cold War. These weapons served from 1952, to 1967. This was considered
to be a lightweight bomb, at it's introduction. When compared to the Mk-5
bomb, shown below, which was developed at the same time, it seems quite
modern. When compare to the 10,000 pound, 20 kt Fat MAn, of just six years
previous, it seems a magnitude of order removed. |

This is a MK23 Katie nuclear projectile, for use in the
the 16" guns of the Iowa class battle ships. Fifty of these were produced,
and each battle ship was equipped to deploy ten. The projectile weighed 1900
pounds and had a probable range of about 25 miles. This was the W19, 11"
artillery shell, adapted to fire from a 16" naval gun. Yield was around 20
kt. The original W19 weighed only 600 pounds. So it seems that the MK23 was
made by stuffing a W19 into a 16" shell casing. Its a shame that no
one thought to use a sabot. Naval tests using 11" saboted shells gave a
range of 115 miles. |

A pair of MK-5 capsules for the Minuteman
Missile. These were the 1 mt versions. The warheads that they held used
uranium fission triggers, to set off a fusion secondary. The burned up sample
on the left, was sent into space, and brought back down to test for reentry.
|
|
The Mk-5 capsules, along with a Mk- 5
fission bomb. The smaller capsules held warheads with about ten times the
power of the larger bomb. |
|
The MK-5 was the first real improvement
on the old Fat Man design. Yield was up to about 120kt, and weight was down
to 3100 pounds. This is more than a thirty fold increase in power
to weight. These bombs were produced in 1952. |
|
The Davy Crockett weighed 76 pounds,
measured 11 x 30, had a range of about two and a half miles, and a yield
of something like 20 tons of TNT ( .02 kt). This may be small by nuclear
standards; but think about twenty tons of TNT going off. Radiation, from
this midget nuke, would kill any one, within a radius of a quarter mile.
