The first test was based on a "… new simpler design. A two-stage thermonuclear bomb that had a much more powerful trigger". This test Grapple X Round C was exploded on 8 November and yielded approximately 1.8 Mt (7.5 PJ). On 28 April 1958 a bomb was dropped that yielded 3 Mt (13 PJ)—Britain's most powerful test.
The Mark 39 design was a thermonuclear bomb and had a yield of 3.8 megatons. [1] It weighed 6,500–6,750 pounds (2,950–3,060 kilograms), [2] and was about 11 feet, 8 inches long (3.556 meters) [2] with a diameter of 35 inches (89 cm). [2] The design is an improved Mark 15 nuclear bomb design (the TX-15-X3 design and Mark 39 Mod 0 were the ...
' Tsar bomb '; code name: Ivan [5] or Vanya), also known by the alphanumerical designation "AN602", was a thermonuclear aerial bomb, and the most powerful nuclear weapon ever created and tested. [ 6 ] [ 7 ] The Soviet physicist Andrei Sakharov oversaw the project at Arzamas-16 , while the main work of design was by Sakharov, Viktor Adamsky ...
In the ensuing fifty years, no one has come up with a more efficient way to build a thermonuclear bomb. It is the design of choice for the United States, Russia, the United Kingdom, China, and France, the five thermonuclear powers. On 3 September 2017 North Korea carried out what it reported as its first "two-stage thermo-nuclear weapon" test. [31]
The casing of a B-41 thermonuclear bomb. The weapon was 12 ft 4 in (3.76 m) long, with a body diameter of 4 ft 4 in (1.32 m). It weighed 10,670 lb (4,840 kg). It was carried only by the B-52 Stratofortress and B-47 Stratojet. It could be deployed in free-fall or retarded free-fall, and had both air burst and ground burst fuzing. [18]
The Supersonic Low Altitude Missile or SLAM was a U.S. Air Force nuclear weapons project conceived around 1955, and cancelled in 1964. SLAMs were conceived of as unmanned nuclear-powered ramjets capable of delivering thermonuclear warheads deep into enemy territory. [1] The development of ICBMs in the 1950s rendered the concept of SLAMs ...
RDS-6s (Russian: РДС-6с, from the Soviet codename for their atomic bombs Russian: Реактивный Двигатель Специальный, lit. 'special jet engine'; American codename: Joe 4) was the first Soviet attempted test of a thermonuclear weapon that occurred on August 12, 1953, that detonated with an energy equivalent to 400 kilotons of TNT.
The Mark 36 was a more advanced version of the earlier Mark 21 nuclear bomb, which was a weaponized version of the "Shrimp" design, the first "dry" (lithium deuteride) fuelled thermonuclear bomb test, which conducted by the United States in the Castle Bravo thermonuclear test in 1954. [1] The Mark 21 bomb was developed and deployed immediately ...
