In addition, the world reacts with horror to the use of this doomsday device. Healing is impossible and Repair Outer Defenses is unusable while the fallout lasts. Any City Centers or Encampments caught in the blast radius will have their HP and Defense Strength reduced to 0.Any unfinished Districts are destroyed and removed from the map.Any Districts and buildings in the affected tiles are also pillaged.All tiles affected are contaminated with radioactive fallout.This is the only way in a normal game that Great People can be killed. Units occupying the affected tiles are destroyed, including Great People.Citizens "working" the affected tiles are eliminated.When an atomic weapon is detonated, several things happen to all the hexes within the blast radius: They cost 16 Gold per turn to maintain (and 20 Uranium to produce in Gathering Storm). When deployed from a Missile Silo or a Nuclear Submarine, they have a Range of 15. Thermonuclear Devices have a blast radius of 2 and apply fallout for 20 turns. They cost 14 Gold per turn to maintain (and 10 Uranium to produce in Gathering Storm). When deployed from a Missile Silo or a Nuclear Submarine, they have a Range of 12 when deployed by a Bomber or Jet Bomber, they are dropped on the target from above and have the same Range as the unit that delivers them. Nuclear Devices have a blast radius of 1 (i.e., the target tile and all adjacent tiles) and apply fallout for 10 turns.

Nukes may be launched at any tile within range of the launch vehicle.

This includes bomber aircraft, Nuclear Submarines, and the Missile Silo. Once a Nuclear or Thermonuclear Device is created, it is added to the player's inventory and can then be used by any unit or improvement capable of deploying it on the map. Second Strike Capability, a Military Policy Card introduced in Rise and Fall, can help with this by cutting nuclear device maintenance costs in half. There is no limit on the number that a player can build, as long as they have enough Gold to support them. Both can be built as a city project in any city once the requisite projects are unlocked, and both require the Uranium resource to produce (1 Uranium in vanilla Civilization VI and Rise and Fall, more in Gathering Storm). There are two categories of atomic weapons: the Nuclear Device and the Thermonuclear Device. Nuclear weapons should not be launched by accident, and the game uses this prompt to confirm the launch.
