    The first test was based on a "… new simpler design. A two-stage thermonuclear bomb that had a much more powerful trigger". This test Grapple X Round C was exploded on 8 November and yielded approximately 1.8 Mt (7.5 PJ). On 28 April 1958 a bomb was dropped that yielded 3 Mt (13 PJ)—Britain's most powerful test.

    Official reports identified them as weapon no. 1 (or bomb no. 1) and weapon no. 2 (or bomb no. 2), with the first's parachute having deployed and the second having crashed into the ground in free-fall without any decrease in its speed. Weapon no. 2 was kept in the forward bomb bay of the aircraft, while weapon no. 1 was in the aft bomb bay. [25]

    The optimum height of burst to maximize this desired severe ground range destruction for a 1 kt bomb is 0.22 km; for 100 kt, 1 km; and for 10 Mt, 4.7 km. Two distinct, simultaneous phenomena are associated with the blast wave in the air: Static overpressure, i.e., the sharp increase in pressure exerted by the shock wave. The overpressure at any ...

    A wooden framed house photographed during a 1953 nuclear test, 5 pounds per square inch (34 kPa) overpressure, full collapse. Upon detonation, a near-ground airburst of a 1-kiloton neutron bomb would produce a large blast wave and a powerful pulse of both thermal radiation and ionizing radiation in the form of fast (14.1 MeV) neutrons.

    Non-nuclear detonation of a nuclear bomb A USAF B-47 bomber developed a fire shortly after take-off and went down with a sealed-pit Mark 39 Mod 1 nuclear weapon on board from an altitude of 1,500 ft (460 m). The detonation of the high explosive material in the bomb created a crater 6 feet (1.8 m) deep and 35 feet (10.7 m) in diameter.

    en.wikipedia.org/wiki/Mark_39_nuclear_bomb

    The Mark 39 design was a thermonuclear bomb and had a yield of 3.8 megatons. [1] It weighed 6,500–6,750 pounds (2,950–3,060 kilograms), [2] and was about 11 feet, 8 inches long (3.556 meters) [2] with a diameter of 35 inches (89 cm). [2] The design is an improved Mark 15 nuclear bomb design (the TX-15-X3 design and Mark 39 Mod 0 were the ...

    The first stage of the bomb was a uranium charge with a capacity of 1.5 Mt, [35] which produced a large amount of radioactive fallout, but more than 97% of the explosion power was provided by a thermonuclear fusion reaction, which does not create a significant amount of radioactive contamination.
