The United States has finally revealed exactly how many nuclear weapons it has. As of 30 September 2009, there were 5,113 nuclear warheads in US military arsenals. According to the Department of Defense, this is down 84% from the peak of 31,255 warheads reached in 1967. In addition, “several thousand additional nuclear warheads are retired and awaiting dismantlement” and the US does not count these as part of its stockpile.
President Obama’s administration hopes that its new openness will encourage other countries, notably China, to come clean on their nuke levels.
No word yet from Iran on whether it has succeeded in creating a nuclear weapon.
