How many nuclear weapons does Russia have?

All figures for nuclear weapons are estimates but, according to the Federation of American Scientists, Russia has 5,977 nuclear warheads - the devices that trigger a nuclear explosion - though this includes about 1,500 that are retired and set to to be dismantled.

Of the remaining 4,500 or so, most are considered strategic nuclear weapons - ballistic missiles, or rockets, which can be targeted over long distances. These are the weapons usually associated with nuclear war.
