The UK's warheads are UK made by the UK Atomic Weapons Establishment (AWE).
The UK lacks an independant warhead delivery system since the cancellation of the Blue Streak in 1960, and currently uses US missiles for the UK submarines.
The UK was the first country to start a nuclear weapons programme and talked the US into starting the Manhatten project.
Once subsumed by the US project, the UK started again post WWII and developed warheads and bombs tested in Australia. They managed to dust a future UK prime minister with fallout as a child in Adelaide.
