Yellow Sun (nuclear weapon)
''Yellow Sun'' was the first British operational high-yield strategic nuclear weapon. The name actually refers only to the outer casing; the warhead (or physics package) was known as "Green Grass" (in Yellow Sun Mk.1) and "Red Snow" (in Yellow Sun Mk.2). The ENI or electronic neutron initiator (generator) was Blue Stone.
==Design==
The casing was some long, in diameter. The Mark 1 version with the Green Grass warhead weighed . The Mk.2 version with the lighter 〔(Dr Richard Moore. University of Southampton Mountbatten Centre for International Studies. )〕 Red Snow warhead had ballast added to maintain overall weight, ballistic and aerodynamic properties, and avoid further lengthy and expensive testing, and changes to the electrical power generating and airburst fuze.
Unlike contemporary U.S. bombs of similar destructive power, Yellow Sun did not deploy a parachute to retard its fall. Instead it had a completely flat nose which induced drag, thereby slowing the fall of the weapon sufficiently to permit the bomber to escape the danger zone. Additionally, the blunt nose ensured that Yellow Sun did not encounter the transonic/supersonic shock waves which had caused much difficulty with barometric fuzing gates which had plagued an earlier weapon, Blue Danube.
Electrical power was supplied by duplicated ram-air turbines located behind the twin air intakes in the flat nose. The earlier Blue Danube design had relied on lead–acid batteries which had proven to be both unreliable and to require time-consuming pre-flight warming.
