From the Cox Report, originally published by U.S. News & World Report.

[edit] Image text

(with some additional comments)

[edit] Fission trigger

• Chemical explosive
• Beryllium (neutron reflector and tamper)
• Plutonium 239
• Deuterium-tritium (DT) gas (booster)

[edit] Fusion devise

• Uranium-238 or 235
• Lithium deuteride (fusion fuel)
• Uranium-235 (thermonuclear sparkplug)

[edit] (Other components)

• Neutron generator
• Foam
• Uranium-238 case

[edit] (Dimensions)

• MIRV length: 5.7 feet
• MIRV base diameter: 1.8 feet
• Explosive power: 300,000 tons of TNT

[edit] Explosive process:

The comression of plutonium with a chemical explosive (above, left) starts a fission explosion that, is boosted by the fusion of DT gas. X-rays then compress the second component, causing a larger fission/fusion.
