Tristan da Cunha
In 1958 as part of an experiment, Operation Argus, the United States Navy detonated an atomic bomb 160 kilometres (100 mi) high in the upper atmosphere about 175 kilometres (109 mi) southeast of the main island.
Nuclear arms race
Behind the scenes, the Soviet government was working on building its own atomic weapons. During the war, Soviet efforts had been limited by a lack of uranium but new supplies in Eastern Europe were found and provided a steady supply while the Soviets developed a domestic source. While American experts had predicted that the Soviet Union would not have nuclear weapons until the mid-1950s, the first Soviet bomb was detonated on August 29, 1949, shocking the entire world. The bomb, named ``First Lightning ''by the West, was more or less a copy of`` Fat Man'', one of the bombs the United States had dropped on Japan in 1945.
Atomic bombings of Hiroshima and Nagasaki
During the final stage of World War II, the United States dropped nuclear weapons on the Japanese cities of Hiroshima and Nagasaki on August 6 and 9, 1945, respectively. The United States had dropped the bombs with the consent of the United Kingdom as outlined in the Quebec Agreement. The two bombings, which killed at least 129,000 people, remain the only use of nuclear weapons for warfare in history.
Smiling Buddha
Smiling Buddha (MEA designation: Pokhran - I) was the assigned code name of India's first successful nuclear bomb test on 18 May 1974. The bomb was detonated on the army base, Pokhran Test Range (PTR), in Rajasthan by the Indian Army under the supervision of several key Indian generals.
Mehola Junction bombing
Hamas bombmaker Yahya Ayyash rigged a Volkswagen Transporter using three large propane tanks and explosives collected from grenades and other ordnance. The bomb was connected to a detonator switch in the driver's controls.
The Blitz
Not all of the Luftwaffe's effort was made against inland cities. Port cities were also attacked to try to disrupt trade and sea communications. In January Swansea was bombed four times, very heavily. On 17 January around 100 bombers dropped a high concentration of incendiaries, some 32,000 in all. The main damage was inflicted on the commercial and domestic areas. Four days later 230 tons was dropped including 60,000 incendiaries. In Portsmouth Southsea and Gosport waves of 150 bombers destroyed vast swaths of the city with 40,000 incendiaries. Warehouses, rail lines and houses were destroyed and damaged, but the docks were largely untouched.
Guildford pub bombings
The Guildford pub bombings occurred on 5 October 1974 when a subgroup of the Provisional Irish Republican Army (IRA) detonated two 6-pound gelignite bombs at two pubs in Guildford, Surrey, England. The pubs were targeted because they were popular with British Army personnel stationed at Pirbright barracks. Four soldiers and one civilian were killed. Sixty-five people were wounded.
Manchester Arena bombing
The 2017 Manchester Arena bombing was an Islamic terrorist attack in Manchester, United Kingdom. On 22 May 2017 a shrapnel - laden homemade bomb was detonated as people were leaving Manchester Arena following a concert by the American singer Ariana Grande. Twenty - three people were killed, including the attacker, and 250 were injured.
Atomic bombings of Hiroshima and Nagasaki
By August 1945, the Allies' Manhattan Project had produced two types of atomic bombs, and the 509th Composite Group of the United States Army Air Forces (USAAF) was equipped with the specialized Silverplate version of the Boeing B - 29 Superfortress that could deliver them from Tinian in the Mariana Islands. Orders for atomic bombs to be used on four Japanese cities were issued on July 25. On August 6, the U.S. dropped a uranium gun - type (Little Boy) bomb on Hiroshima, and American President Harry S. Truman called for Japan's surrender, warning it to ``expect a rain of ruin from the air, the like of which has never been seen on this earth. ''Three days later, on August 9, a plutonium implosion - type (Fat Man) bomb was dropped on Nagasaki. Within the first two to four months following the bombings, the acute effects of the atomic bombings had killed 90,000 -- 146,000 people in Hiroshima and 39,000 -- 80,000 in Nagasaki; roughly half of the deaths in each city occurred on the first day. During the following months, large numbers died from the effect of burns, radiation sickness, and other injuries, compounded by illness and malnutrition. In both cities, most of the dead were civilians, although Hiroshima had a sizable military garrison.
Enola Gay
The Enola Gay (/ ɪˈnoʊlə ˈɡeɪ /) is a Boeing B - 29 Superfortress bomber, named for Enola Gay Tibbets, the mother of the pilot, Colonel Paul Tibbets, who selected the aircraft while it was still on the assembly line. On 6 August 1945, during the final stages of World War II, it became the first aircraft to drop an atomic bomb. The bomb, code - named ``Little Boy '', was targeted at the city of Hiroshima, Japan, and caused unprecedented destruction. Enola Gay participated in the second atomic attack as the weather reconnaissance aircraft for the primary target of Kokura. Clouds and drifting smoke resulted in a secondary target, Nagasaki, being bombed instead.
Thermos bomb
Thermos bomb was the informal name for the AR-4, an air dropped anti-personnel mine used by the Italian Air Force during World War II. Large numbers were used against Malta and in the Middle East. It was named for its superficial appearance to a Thermos bottle, a popular brand of vacuum flask. The bomb was a cylinder long and weighing . It could be fitted with a very sensitive motion-sensitive fuze that would detonate if any attempt was made to move it, and could be lethal in the open up to around away. Because of this, unexploded Thermos bombs were normally destroyed where they fell, either by attaching a long piece of string to them and giving it a jerk, or detonating a small explosive charge next to them.

Centennial Olympic Park bombing
The Centennial Olympic Park bombing was a domestic terrorist pipe bombing attack on the Centennial Olympic Park in Atlanta, Georgia, on July 27 during the 1996 Summer Olympics. The blast directly killed 1 person and injured 111 others; another person later died of a heart attack. It was the first of four bombings committed by Eric Rudolph. Security guard Richard Jewell discovered the bomb before detonation and cleared most of the spectators out of the park. Rudolph, a carpenter and handyman, had detonated three pipe bombs inside a U.S. military ALICE Pack. Motivated by what he considered to be the government's sanctioning of ``abortion on demand '', Rudolph wanted to force the cancellation of the Olympics.

Atomic bombings of Hiroshima and Nagasaki
During the final stage of World War II, the United States detonated two nuclear weapons over the Japanese cities of Hiroshima and Nagasaki on August 6 and 9, 1945, respectively. The United States dropped the bombs after obtaining the consent of the United Kingdom, as required by the Quebec Agreement. The two bombings killed 129,000 -- 226,000 people, most of whom were civilians. They remain the only use of nuclear weapons in the history of warfare.
Pacific War
On 6 August 1945, the U.S. dropped an atomic bomb on the Japanese city of Hiroshima in the first nuclear attack in history. In a press release issued after the atomic bombing of Hiroshima, Truman warned Japan to surrender or "...expect a rain of ruin from the air, the like of which has never been seen on this earth." Three days later, on 9 August, the U.S. dropped another atomic bomb on Nagasaki, the last nuclear attack in history. More than 140,000–240,000 people died as a direct result of these two bombings. The necessity of the atomic bombings has long been debated, with detractors claiming that a naval blockade and aerial bombing campaign had already made invasion, hence the atomic bomb, unnecessary. However, other scholars have argued that the bombings shocked the Japanese government into surrender, with Emperor finally indicating his wish to stop the war. Another argument in favor of the atomic bombs is that they helped avoid Operation Downfall, or a prolonged blockade and bombing campaign, any of which would have exacted much higher casualties among Japanese civilians. Historian Richard B. Frank wrote that a Soviet invasion of Japan was never likely because they had insufficient naval capability to mount an amphibious invasion of Hokkaidō.
Uranium
Two major types of atomic bombs were developed by the United States during World War II: a uranium-based device (codenamed "Little Boy") whose fissile material was highly enriched uranium, and a plutonium-based device (see Trinity test and "Fat Man") whose plutonium was derived from uranium-238. The uranium-based Little Boy device became the first nuclear weapon used in war when it was detonated over the Japanese city of Hiroshima on 6 August 1945. Exploding with a yield equivalent to 12,500 tonnes of TNT, the blast and thermal wave of the bomb destroyed nearly 50,000 buildings and killed approximately 75,000 people (see Atomic bombings of Hiroshima and Nagasaki). Initially it was believed that uranium was relatively rare, and that nuclear proliferation could be avoided by simply buying up all known uranium stocks, but within a decade large deposits of it were discovered in many places around the world.
