UPDATE: I don't usually fix these off-week posts. They're hurried for a reason. On the other hand, blah blah work schedule here I am with some free time Monday morning, and this one is particularly egregious and easy to fix.
At this point, I feel an overwhelming urge to indulge my inner Geoff Crowther and blame the Atlee Government for blowing up Christmas. Yes, it was the Conservatives who carried out the 1957/8 Christmas Island tests, and the Conservatives who authorised Short Granite and Orange Herald. Short Granite was a hydrogen fizzle, which was perhaps not unexpected, because Orange Herald was ready in reserve. Orange Herald popped off at 800 kT. This qualified Britain for membership in the Megaton Club, and allowed it to hold up its head high at Security Council meetings and sneer at the French. Although this seems like rewriting the rules of the H-Bomb Club to me, because Orange Herald was a regular old fission bomb. Whatever. I'm not on the Security Council, and an 800kt fission bomb is a bravura performance in itself, and the Grapple X test, a year later, demonstrated some remarkable weapons design that
Norman Dombey and Eric Groves probably know more about than they're allowed to say.
Notwithstanding being a cool design, any 800kT fission weapon is going to be dangerously susceptible to "multi-kiloton events," and t
he major safety mechanism on the descendant Violet Club is some real Cold War dark humour. These monsters theoretically armed the V-bomber force for a few years in small numbers, although no V-bomber ever took off with one, the RAF having more sense than whoever it was in the decision chain that signed off on Violet Club. Presumably, any crash-landing related "events" would be reserved for WWIII, when public opinion would be jaded by more pressing concerns like rampaging atomic zombies.
As for blaming the Atlee Government, we can get there by arguing that the insanely accelerated British programme wouldn't have been necessary if the Atlee Government had launched a "Super" programme when the Truman Administration announced that it was going to develop an H-bomb, back in January of 1950. It makes for a kinder treatment of late-Fifties Conservative defence policy than dwelling on the fact that the upshot of Grapple diplomacy was that the British got access to American designs, pretty much ending independent British atomic weapons development, which is the kind of thing you expect the core Conservative voter to support.
Oh, wait, no, that probably means no tax cut. Never mind.
By this point, I'm getting a few months ahead of myself in terms of postblogging. What I want to talk about is the 1949 Nuffield Foundation grants. Presumably all of the stuff that these grants facilitated is now ancient news after decades of work at Los Alamos, Scandia, Oakridge, Livermore and the Aldermaston in the years since, but the public doesn't always know anything about that except for what indiscreet persons such as the President of Russia might have let slip.
