The Dongfeng 5 (simplified Chinese: 东风-5; traditional Chinese: 東風-5; pinyin: Dōng Fēng Wǔ; lit. 'East Wind 5') or DF-5 is a second-generation two stage Chinese intercontinental ballistic missile. It has a length of 32.6 m and a diameter of 3.35 m. It weighs in at 183,000 kilograms and it has an estimated range of 12,000 to 15,000 kilometers. The DF-5 had its first flight in 1971 and was in operational service 10 years later.



One of the limitations of the missile is that it takes between 30 and 60 minutes to fuel. The DF-5 is due to be replaced by the solid-fuelled DF-41. Around 2015, the newest variant DF-5B force are believed to have received a MIRV upgrade; according to Business Insider, with DF-5B: "China has the ability to deliver nuclear warheads nearly anywhere on earth (outside of South America, at least)".

Ivy King was the largest pure-fission nuclear bomb ever tested by the United States. The bomb was tested during the Truman administration as part of Operation Ivy. This series of tests involved the development of very powerful nuclear weapons in response to the nuclear weapons program of the Soviet Union. The production of Ivy King was hurried to be ready in case its sister project, Ivy Mike, failed in its attempt to achieve a thermonuclear reaction. The Ivy King test actually took place two weeks after the Mike test. Unlike the Mike bomb, the Ivy King device could theoretically have been added to United States' nuclear arsenal, because it was designed to be air-deliverable. On November 16, 1952 at 11:30 local time (23:30 GMT) a B-36H bomber dropped the bomb over a point 2,000 feet (610 m) north of Runit Island in the Enewetak atoll, resulting in a 540 kiloton explosion at 1,480 feet (450 m). The tropopause height at the time of the detonation was about 58,000 feet (18 km). The top of the King cloud reached about 74,000 feet (23 km) with the mushroom base at about 40,000 feet (12 km).The Ivy King bomb, designated as a Mk-18 bomb and named the "Super Oralloy Bomb", was a modified version of the Mk-6D bomb.



Instead of using an implosion system similar to the Mk-6D, it used a 92-point implosion system initially developed for the Mk-13. Its uranium-plutonium core was replaced by 60 kg of highly enriched uranium (HEU) fashioned into a thin-walled sphere equivalent to approximately four critical masses. The thin-walled sphere was a commonly used design, which ensured that the fissile material remained sub-critical until imploded. The HEU sphere was then enclosed in a natural-uranium neutron reflector. To physically prevent the HEU sphere collapsing into a critical condition if the surrounding explosives were detonated accidentally, or if the sphere was crushed following an aircraft accident, the hollow center was filled with a chain made from aluminum and boron, which was pulled out to arm the bomb. The boron-coated chain also absorbed the neutrons needed to drive the nuclear reaction.The primary designer of the Super Oralloy Bomb, physicist Ted Taylor, later became a vocal proponent of nuclear disarmament.
