Climax atom bomb test. High-speed footage showing the fireball at the moment of detonation. This nuclear weapons test took place on 4 June 1953, at the Nevada Test Site, USA. Codenamed Climax, it was the 11th test in the Operation Upshot-Knothole series. It was detonated as an air drop, and had a yield of 61 kilotons.

Air drop for first Soviet megaton hydrogen bomb. Footage of the air drop for the detonation of the first megaton-range hydrogen bomb (RDS-37) test by the USSR on 22 November 1955 at the Semipalatinsk Test Site in what is now Kazakhstan. Hydrogen bombs (thermonuclear weapons) use nuclear fusion reactions and are many times more powerful than the first atomic bombs that only used nuclear fission. A total of 456 Soviet nuclear tests were conducted at the Semipalatinsk site between 1949 and 1989.

Soviet Totsk nuclear test, 1954, fireball and mushroom cloud. Also known as the Totskoye nuclear exercise and Joe 8, this test of a Soviet nuclear bomb took place on 14 September 1954 near Totskoye village in the Orenburg region of Russia. Around 45,000 troops were stationed in trenches close to ground zero and then marched through the area where the blast took place, wearing protective gear and radiation dose monitors, and engaging in military exercises. The atom bomb (an RDS-4 nuclear fission design) had a yield of 40 kilotons, was dropped by a Tu-4 bomber, and exploded at 06:33 UTC at a height of 350 metres above the ground.

UKRAINE (RELEASED ON JULY 4, 2024) (----EDITORIAL USE ONLY – MANDATORY CREDIT - ‘RUSSIAN DEFENSE MINISTRY/ HANDOUT' - NO MARKETING NO ADVERTISING CAMPAIGNS - DO NOT OBSCURE LOGO----)- Russian Defense Ministry on Thursday (July 4) released a new video that show a Su-34 bomber aircraft dropping bombs on Ukrainian positions. The ministry said “Su-34 bombers struck enemy personnel and equipment within the operational zone of the Western Military Group. The strike was conducted using unguided aviation bombs OFAB-250 with a universal planning and correction module." The Su-34 is a Russian twin-engine, twin-seat fighter-bomber aircraft designed primarily for tactical bombing and strike missions. It is developed by Sukhoi, a renowned Russian aerospace company. The Su-34 is characterized by its robust airframe, advanced avionics, and a wide array of weapon systems capable of engaging ground and naval targets. It features a distinctive side-by-side seating arrangement for its two crew members, providing both with good visibility and operational efficiency during missions. The Su-34 is known for its long-range capability, sophisticated electronic warfare systems, and the ability to carry a diverse range of bombs, missiles, and other munitions.(Footage by RUSSIAN DEFENSE MINISTRY /Anadolu Agency via Getty Images)

Dominic Encino atomic test airdrop, high-speed footage. Operation Dominic was a series of 31 atom bomb tests conducted in the Pacific by the US military in 1962. The locations included Johnston Atoll, Kiritimati, and Kiribati. These tests were among the last atmospheric tests carried out by the USA, with the Limited Test Ban Treaty being ratified in 1963. This test, codenamed Encino, took place on 12 May 1962 at Kiritimati. The tenth test in the series, it was an airdrop with a yield of 500 kilotons.

Charlie atom bomb test, showing the moment of detonation and the rising mushroom cloud. This nuclear weapons test took place on 22 April 1952, at the Nevada Test Site, USA. Codenamed Charlie, it was the 3rd test in the Operation Tumbler-Snapper series. It was detonated following an air drop, and had a yield of 31 kilotons. This test was also part of the Desert Rock exercises, where US Army troops undertook nuclear battlefield training.

US hydrogen bomb air drop mission. US B52 bomber releasing a thermonuclear weapon (hydrogen bomb) during a nuclear test during the Cold War. The USA carried out a number of hydrogen bomb tests. This one is an air drop, with the bomb descending by parachute after being released from the bomber. This gives the aircraft time to reach a safe distance before detonation. Hydrogen bombs result in nuclear fusion and are immensely powerful, with yields much greater than atomic bombs based on nuclear fission. Major US tests involving air drops of thermonuclear weapons included Operation Ivy and Operation Redwing in the 1950s, along with later tests in the 1960s and 1970s.

Desert Rock IV exercise and Charlie atom bomb, 1952. This footage soldiers observing the rising mushroom cloud following the moment of detonation. Soldiers are also shown being tested for contamination with radioactive materials. This nuclear weapons test took place on 22 April 1952, at the Nevada Test Site, USA. Codenamed Charlie, it was the 3rd test in the Operation Tumbler-Snapper series. It was detonated following an air drop, and had a yield of 31 kilotons. This test was also part of the Desert Rock exercises, where US Army troops undertook nuclear battlefield training. These troops are taking part in the Desert Rock IV exercise.
