Red Snow was a British thermonuclear weapon. Its physics package was identical to that of the United States W28 nuclear warhead used in the B28 nuclear bomb and AGM-28 Hound Dog missile, with an explosive yield of approximately 1.1 megaton.
The Red Snow warhead was developed after a September 1958 decision to adopt the US warhead for British use, following the 1958 US-UK Mutual Defence Agreement. It entered service in 1961, remaining in use until 1972, when it was replaced by the WE.177 bomb. Perhaps 150 were produced.
Red Snow was used as both a free-fall bomb and as the warhead of the Blue Steel missile. In the gravity bomb role, it was fitted into the casing of the Yellow Sun weapon, even though the Red Snow warhead was considerably smaller than that of the original Yellow Sun bomb.
The Red Snow warhead was later reduced in size, weight and yield, and fitted with a smaller more modern primary, intended as a Red Beard replacement. Known as Una, this was later reduced in diameter and renamed Ulysses as the warhead intended for the UK warhead for the Skybolt project.
Famous quotes containing the words red and/or snow:
“The love that kisses with a homicide
In robes of red generation resurrects.”
—George Barker (b. 1913)
“Physical force has no value, where there is nothing else. Snow in snow-banks, fire in volcanoes and solfataras is cheap. The luxury of ice is in tropical countries, and midsummer days. The luxury of fire is, to have a little on our hearth; and of electricity, not the volleys of the charged cloud, but the manageable stream on the battery-wires. So of spirit, or energy; the rests or remains of it in the civil and moral man, are worth all the cannibals in the Pacific.”
—Ralph Waldo Emerson (1803–1882)
