what is the strongest type of nuclear bomb
Tsar Bomba Tsar Bomba (Russian: Царь-бомба; "Tsar-bomb") was the Western nickname for the Soviet RDS-220 hydrogen bomb (code name Ivan[3] or Vanya), the most powerful nuclear weapon ever detonated. Its test on 30 October 1961 remains the most powerful man-made explosion in history. It was also referred to as Kuzkina mat (Russian: Кузькина мать; "Kuzma's mother"),[4] possibly referring to Nikita Khrushchev's promise to show the United States a Kuzkina mat (an idiom roughly translating to "We'll show you!") at a 1960 session of United Nations General Assembly.[5][6]
Atomic bombings of Hiroshima and Nagasaki Due to crosswind, the bomb missed the aiming point, the Aioi Bridge, by approximately 800 ft (240 m) and detonated directly over Shima Surgical Clinic.[139] It released the equivalent energy of 16 kilotons of TNT (67 TJ), ± 2 kt.[136] The weapon was considered very inefficient, with only 1.7% of its material fissioning.[140] The radius of total destruction was about 1 mile (1.6 km), with resulting fires across 4.4 square miles (11 km2).[141]
