Britain's hydrogen bomb, operation grapple

[@ronholfly]

Thanks for the memories, I was serving in the RAF and our squadron got posted there during Operation Grapple. I remember that morning very well, we sat on the ground with our backs to the detonation, at zero count the heat felt like someone had just placed an electric fire on your back, the brightness was so vivid we could see the bones in our hands that covered our eyes. A moment in my life that will live with me forever.

[@BenNewton-c6z]

From a historical perspective - it was important for Britain to maintain its status as a 'great power' as one of the big three after World War Two (with the USA and Russia) and as one of the five permanent members of the United Nations security council. At this point in 1958 only the USA and Russia were nuclear powers with both fission and fusion devices - atomic and hydrogen bombs. The testing of such devices was then followed by France and China in the 1960s. For sure such archive footage is both beautiful and awe-inspiring to watch; however, you can only wonder at the damage inflicted on the earth's stratosphere by nuclear tests like these - which probably explains why they were partially banned in 1963. Let's hope such weapons are never used in anger by ANY state.

Survivors will just have to follow Steve Guttenberg's example in 'The Day After Tomorrow.'

A 2 stage nuclear munition.The first flash is a fission detonation.The second flash comes from the hydrogen fuel being lit by the first fission reaction.

[@SuperpowerBroadcasting]

@@stefanimurray8381 No. Those processes occur within microseconds. The double flash humans can perceive relates to the shock front becoming opaque to the light within. This short time period between light maxima increases as the yield increases. For example, a 2-stage nuke with a yield of 20 kt would not have a noticeable double flash. But if a single stage 100% fission bomb had a yield like this one, it would have the same double flash. Ivy King is the largest nuclear test using a fission device (500 kt). It produced a clearly noticeable double flash.

[@Sciolist]

​@@SuperpowerBroadcastingOrange herald was the largest fission bomb, it was detonated during early grapple series test after 1st iteration of British H bomb produced disappointing yield.

[@deletdis6173]

​@@SciolistI thought Ivy King was the largest fission weapon?

[@Sciolist]

@@deletdis6173 no orange herald was, it had some fusion fuel added but later analysis showed that it didn't boost yield. Ivy king didn't have any fusion fuel and was efficient, getting 500kt from 60kg of HEU, orange herald got +700kt from 120 kg of HEU though of lower enrichment. Both bombs were ment as a backup option. Ivy mike was physically large and heavy so ivy king design was produced till deliverable megaton range bombs became available after castle test series. Orange herald development followed same thinking but because it used up a very large chunk of British HEU production none were produced for stockpiling. By the time stockpiling decision had to be made britain had overcome its initial difficulties with H-bomb, after testing multimegaton bombs there was there was no reason to continue with a very fissile material expensive fission bomb.

[@tomdecuca3627]

If you are asking why they detonated it off the ground- it keeps the fireball from scorching the earth, which creates far less "fallout."

[@mikejosef2470]

It's also a better test in terms of how the bomb would actually be used. Aside from the initial heat pulse hitting more people due to lack of shade from low lying buildings, the shock front directly from the detonation itself is reinforced by the ground reflected shockwave when a bomb is detonated at the right altitude. This altitude varies with the yield of the bomb.

[@trolleriffic]

They wanted to test whether the bomb worked and did so as expected, but they didn't want to damage anything on the ground if it could be avoided. As tom mentioned, having the fireball touch the ground causes large amounts of soil and rock to be vaporised and smashed to dust which then gets heavily irradiated and mixed with radioactive materials from the bomb itself. That would have resulted in a massive amount of potentially very dangerous and persistent fallout, whereas a high altitude burst produces only a tiny fraction as much.
