3. Nuclear Weapons in Britain Trident is the name given to Britain’s nuclear weapon’s arsenal. Next year Britain will decide whether to build a new generation of nuclear missile submarines.

4. Nuclear Weapons in Britain The current submarines each carry up to 16 missiles, and each missile can carry up to 12 warheads. Each warhead has a maximum explosive yield of 100 kilotons (the equivalent of 100,000 tons of TNT). That’s about six times as powerful as the bomb which destroyed Hiroshima. A 100kt bomb detonated in the air over central London would probably kill about 250,000 people, almost instantly. One Vanguard-class submarine, carrying 16 missiles with 12 warheads each, could therefore destroy 48 cities.

5. Nuclear Weapons in Britain At least one nuclear submarine is constantly on patrol. According to the Royal Navy, the Trident missile has a range of 4,000 nautical miles, or 7,500km. The cost of replacing the submarines is expected to be up to £26 billion over the lifetime of the project. Only the prime minster has the authority to order the launch of nuclear weapons. When a new prime minister is elected, they give the commanders of each of the four submarines a sealed letter, known as the letter of last resort.
