How Nuclear Tests were conducted
Plumbob Shot Tower - 1957
Shot Smoky - August 31, 1957
The Smoky shot tower soars 700 feet into the air above Yucca Flat. The first atomic test
tower of this height, the structure may well be the tallest steel tower of its type.
The tower was designed by Holmes & Narver, inc.
Plumbbob Shot Balloon - 1957
Cab attached, a shot balloon begins ascent during a test run at the Nevada Test Site.
Inflation is accomplished by inserting a metal probe with thousands of holes into a plastic
filler tube attached at the bottom of the big balloon.
- Plumbbob (1957) - 13 Balloons
- Hardtack (1958) - Yucca
- Hardtack II (1958) - 11 Balloons

Detonated in Outer Space (High Altitude Detonations)
Shot Orange (August 12, 1958)
Yield 3.8 Megatons
Location of launch: Johnston Island
- Hardtack (1958) - 2 space detonations

Air to Air Missile Test
Shot John (July 19, 1957)
Yield: About 2 Kilotons
Location of launch: Nevada Test Site
A Live nuclear rocket accelerates past the launching F-89 Scorpion. Once launched,
the Scorpion banks at about 70 degrees to evade the forthcoming nuclea explosion.
The rocket project was begun in early 1954 and code named "Genie" by the Air Research
and Development Command.
