The U.S. nuclear arsenal consists of a variety of nuclear weapons maintained by the United States Department of Defense. This arsenal includes strategic warheads deployed on intercontinental ballistic missiles (ICBMs), submarine-launched ballistic missiles (SLBMs), and strategic bombers. The primary goal of this arsenal is to deter potential adversaries and ensure national security. The total number of nuclear warheads in the U.S. arsenal is estimated to be around 5,800, with a portion actively deployed and others in reserve or awaiting dismantlement. The U.S. also participates in various arms control agreements, such as the New START treaty, to manage and reduce nuclear stockpiles.
