Castle Bravo was the first in a series of high-yield thermonuclear weapon design tests conducted by the United States at Bikini Atoll, Marshall Islands, as part of Operation Castle. Detonated on 1 March 1954, the device remains the most powerful nuclear device ever detonated by the United States and the first lithium deuteride -fueled ...
English: A simple graphic showing comparative nuclear fireball radii for a number of different tests and warheads. From largest to smallest, the diameter are: Tsar Bomba — 50 Mt — 4.6 km (2.9 mi) Castle Bravo — 15 Mt — 2.84 km (1.76 mi) W59 warhead (Minuteman missile) — 1 Mt — .96 km (0.60 mi)
Comparative fireball radii for a selection of nuclear weapons. [citation needed] Contrary to the image, which may depict the initial fireball radius, the maximum average fireball radius of Castle Bravo, a 15-megatonne yield surface burst, is 3.3 to 3.7 km (2.1 to 2.3 mi), [6] [7] and not the 1.42 km displayed in the image.
Operation Castle was an unqualified success for the implementation of dry fuel devices. The Bravo design was quickly weaponized and is suspected to be the progenitor of the Mk-21 gravity bomb. The Mk-21 design project began on 26 March 1954 (just three weeks after Bravo), with production of 275 weapons beginning in late 1955.
The G506 was a United States Army Ordnance Corps supply catalog designation for the 1 + 1 ⁄ 2-ton, 4X4, truck chassis built in large numbers by the Chevrolet Motor Division of GM. Their official model numbers were initially the "G4100", and later the "G7100" series. [ 4 ]

Dodge was the U.S. Army's main supplier of 1 ⁄ 2 ‑ton trucks, and its sole supplier of both 3 ⁄ 4 ‑ton trucks and 1 1 ⁄ 2 ‑ton 6x6 trucks in World War II. [5] With over a quarter million units built through August 1945, the G-502 3 ⁄ 4 ‑tons were the most common variants in the WC‑series.
