Tsar a victim Russias Supreme Court has declared the countrys last Emperor Nicolas the second and his family to be victims of political repression. The ruling comes ninety years after their execution. The decision ends years of efforts of the Romanov's descendants to reclassify the killings.

Tsar Bomba - King of the Bombs - 57,000,000 Tonnes of TNT The Tsar Bomba _______________ October 30th 1961 - The Tsar Bomba, King of the Bombs, Царь-бомба or Big Ivan. This footage is courtesy of the documentary "Trinity and Beyond", directed by Peter Kuran, and other footage is courtesy of the Discovery channel. The original footage was from declassified Soviet Archives. The music used is from The Planets Suite composed by Gustav Holst. The movement is 'Mars: the Bringer of War' Before I get into the details of the test, I want to clear up something very important. The title of this video is "Tsar Bomba - King of the Bombs - 57,000,000 Tonnes of TNT". Understand now that this test wasn't the result of a detonation of 57,000,000 Tonnes of TNT, but rather the nuclear yield EQUIVALENT of a detonation of 57,000,000 Tonnes of Trinitrotoluene. The actual weight of the device was 27 tonnes. And coincedentaly, one tonne is taken as a metric tonne, or 1000 kilograms - (2200lbs). All units used in physics are metric. The reason the yield equivalent system is used is because the energy released from the explosion of a set amount of TNT is a constant. The bomb was designed as a 100 Megaton device, not a 50 Megaton device. This was due to its 3 stage design: fission-fusion-fission. There is fission initiator that when detonated, begins a fusion reaction. Then there is a further fission detonation of a Uranium tamper which boosts the yield by 50 Megatons. For the test, the Tsar had its Uranium tamper replaced with lead to reduce the maximum yield by half (To 50 Megatons). The blast yield was equal to that of a blast of 57,000,000 Tonnes of TNT....or to put that into context: The weight of 270 Empire State Buildings worth of TNT. This makes the Tsar the most powerful nuclear device ever detonated in history. Think of the destruction at Hiroshima. The Tsar was 3800 times more powerful than Hiroshima. The bomb's weight was 27 tonnes, and its dimensions were: 8 meters (26ft) in length, and 2 meters (6.5ft) in diameter. It was air-dropped, from a modified Tupolev Tu-95 Bear, and it used a nylon parachute to slow its decent to give the crew time to escape. The bomb was dropped from an altitude of 34,500 feet AGL (10,500 meters), and it detonated a little over three minutes later at an altitude of 13,100 feet AGL (4,000 meters). In this time: The Tu-95, travelling at a ground speed of 480kts (552mph, 864kph), travelled into the safe zone (about 45km from ground zero) and was therefore 79km away from the blast. When the bomb detonated, immediately the temperature directly below and surrounding the detonation would have risen to millions of degrees. The pressure below the blast was 300 pounds per square inch, over three times the pressure in a car tyre. The light energy released was so powerful that it was visible even at 1000km (621 miles), with cloudy skies. The shockwave was powerful enough to break windows at even up to 900 kilometres (560 miles) from the blast. The shockwave was recorded orbiting the earth 3 times. The mushroom cloud rose to an altitude of 64,000 meters (210,000 feet) before levelling out. The thermal energy from the blast was powerful that it could cause 3rd degree burns to a human standing 100 km (62 miles) away from the blast. The radius of the fireball was 2.3 kilometres (1.4 miles). The blast radius (area in which total destruction ensured) was 13km (8 miles). The most important thing to note is that this bomb was designed as a 100 Megaton device (Yield equivalent of 0.1 trillion tonnes of TNT). If detonated, everything within a 48 kilometer (30 mile) diameter would be vaporised. Everything within a 195 kilometer (120 mile) diameter would be incinerated in a fireball. This would ensure total destruction of a large city like New York, Paris or London, as well as devastation on its outskirts.

The largest nuclear weapon ever: Tsar Bomba 50 Megatons Tsar Bomba was the largest nuclear weapon ever constructed or detonated. It was detonated at 4000 m altitude the 30th of October 1961 at Mityushikha Bay test range, Novaya Zemlya Island. It had a yield of 50 Megatons.

Tsar Bomba - The King of Bombs Tsar Bomba, nicknamed 'Big Ivan' by its makers, was the largest nuclear bomb ever built. With a yield of 50 megatons, it was 4000 times more powerful then the bomb that devastated Hiroshima. This video shows various important aspects of the bomb, including its development at Arzamas-16, the secret Soviet nuclear weapons research facility and its transportation to the Tu-95 bomber, which was painted white for the test to reflect the heat of the blast. Several different views of the explosion are also shown, including several filmed from the air and ground alike. The last few shots are of the ground zero several days after the test.

tsar bomba La Bomba del Zar (en ruso: Царь-бомба, Tsar Bomba), fue una bomba nuclear desarrollada por la Unión Soviética responsable de la mayor explosión nuclear de la historia. Fue detonada el 30 de octubre de 1961 como demostración, a 4 km de altitud. El lugar de la detonación fue Nueva Zembla, un archipiélago ruso situado en el Océano Ártico, y fue lanzada por un bombardero Tupolev Tu-95 modificado. Su nombre deriva de la campana Tsar Kolokol, la más grande del mundo (100 tm), situada en Moscú, y del Cañón del Zar, el cañón imperial. Ambos fueron construidos más con miras a demostrar la superioridad tecnológica rusa que como objetos realmente útiles, como fue el caso de estas bombas. Durante su desarrollo, su nombre en clave fue Iván (Иван). Debido a su enorme tamaño, esta bomba no era práctica para su uso real, y fue creada principalmente con motivos propagandísticos debido a la intensa rivalidad existente en la Guerra Fría. No se tiene constancia de la construcción de otra bomba de potencia semejante. Las bomba del Zar era una bomba de hidrógeno de tres etapas, con una potencia total de 50 megatones (la estimación inicial de los Estados Unidos fue de 57 Megatones, pero desde 1991 las fuentes soviéticas la citan como de "sólo" 50 Mt). El diseño inicial hacía factible una explosión de 100 Mt, pero dicha potencia fue reducida poco antes de la detonación, y agregada otra bomba. Nikita Kruschev dijo en su momento que la explosión sería de 100 Mt, como se pudo oír en sus declaraciones. Los dispositivos nucleares del tipo usado en esta bomba fueron desarrollados por un equipo de físicos encabezado por Igor Kurchatov, y formado por Andrei Sakharov, Victor Adamsky, Yuri Babayev, Yuri Smirnov y Yuri Trutnev.
