Variable yield weapon, most powerful US weapon in active service. B53 nuclear bomb: 9,000 38,000 Was the most powerful US bomb in active service until 1997. 50 were retained as part of the "Hedge" portion of the Enduring Stockpile until completely dismantled in 2011. [3] The Mod 11 variant of the B61 replaced the B53 in the bunker busting role.
The nuclear shaped charge concept was also studied extensively in the 1980s as part of Project Prometheus, along with bomb-pumped lasers. Using a combination of explosive wave-shaping and "gun-barrel" design, up to 5% of a small nuclear bomb could reportedly be converted into kinetic energy driving a beam of particles with a beam angle of 0.001 ...
In an implosion-type nuclear weapon, polygonal lenses are arranged around the spherical core of the bomb. Thirty-two "points" are shown. Other designs use as many as 96 or as few as two such points. An explosive lens—as used, for example, in nuclear weapons—is a highly specialized shaped charge.
According to an audit by the Brookings Institution, between 1940 and 1996, the US spent $11.3 trillion in present-day terms [6] on nuclear weapons programs. 57 percent of which was spent on building delivery mechanisms for nuclear weapons. 6.3 percent of the total, $709 billion in present-day terms, was spent on weapon nuclear waste management ...
According to an audit by the Brookings Institution, between 1940 and 1996, the US spent $11.3 trillion in present-day terms [107] on nuclear weapons programs. 57% of which was spent on building nuclear weapons delivery systems. 6.3% of the total$, 709 billion in present-day terms, was spent on environmental remediation and nuclear waste ...
Although India's nuclear programme and its details are highly classified, international figures suggest that India possesses about 172 nuclear weapons as per 2024 estimate. In 1999, India was estimated to have 800 kg of separated reactor-grade plutonium, with a total amount of 8,300 kg of civilian plutonium, enough for approximately 1,000 ...
Trump in 2018 reneged on a deal struck by his predecessor Barack Obama in 2015 in which Iran agreed to curb uranium enrichment, which can yield material for nuclear weapons, in return for the ...
As thermonuclear weapons represent the most efficient design for weapon energy yield in weapons with yields above 50 kilotons of TNT (210 TJ), virtually all the nuclear weapons of this size deployed by the five nuclear-weapon states under the Non-Proliferation Treaty today are thermonuclear weapons using the Teller–Ulam design.
