The precise number is classified, & not publicly available...
Probably there are 150-200 British built nuclear warheads for the American supplied Trident SLB Missile system. It's also possible that some smaller nuclear warheads have been developed for the Tomahawk cruise missiles also carried by Royal Navy nuclear submarines, but this is speculative!
Officially, all the "free-fall" nuclear bombs once carried by the RAF's "Strike Command"/ "V Force" aircraft have been decommissioned, but many suspect that some (maybe a hundred or so) have been upgraded & retained for "contingencies".
There are no longer any US controlled nuclear warheads based permanently in Britain, although nuclear armed American submarines operate routinely from UK naval bases under joint facility agreements between UK & US Governments.
The British Army (as per current NATO doctrine/ international arms control agreements/ treaties) no longer maintains/ controls any tactical nuclear weapons systems.
Bottom line, however, is that no-one apart from the Prime Minister, Intelligence & Defence Chiefs, & probably some very senior Civil Servants, knows the exact number of nuclear weapons currently retained by the UK: in order effectively to deter, it's best to keep potential enemies guessing...
Yes, there is nuclear energy in nuclear bombs. It is released in a few microseconds when they are detonated.
Nuclear bombs before the 60s were referred to as atom bombs, because the term Nuclear hadn't been discover yet. Nuclear bombs today, are generally Hydrogen bombs, or fusion bombs. They are significantly more powerful, able to places about the size of Rhode Island. Atom bombs,which were mostly uranium and plutonium, lack the destructive power of Nuclear or Fusion bombs.
yes there is extreme amounts of gamma radiation in in nuclear bombs
Radioactivity
because it has heat inside that can burn you to pieces
England tested its nuclear bombs at maralinga and woomera in south Australia
At this time the US builds no nuclear bombs. A small number of existing bombs are refurbished as needed.
No nuclear bombs were tested on Easter Island.
none, australia is not a nuclear power
Some bombs are nuclear. But most bombs are not nuclear.
Well, to my research there hasn't been any nuclear bombs, Aussie has built.
in many places
None
Russia has roughly 3500 nuclear warheads at the time of this writing and the number is slowly falling.
there were two types of nuclear bombs. A "gun type" bomb and an implosion type one with a plutonium core
