The United States possesses the world’s second-largest nuclear arsenal, comprising approximately 5,800 warheads. Its nuclear delivery systems include intercontinental ballistic missiles (ICBMs), submarine-launched ballistic missiles (SLBMs), and strategic bombers. These systems are designed to ensure second-strike capability—the ability to retaliate after absorbing a nuclear attack.
U.S. nuclear strategy has historically relied on the doctrine of mutually assured destruction (MAD), which assumes that the threat of catastrophic retaliation deters nuclear war. The United States is a signatory to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), which aims to prevent the spread of nuclear weapons and promote disarmament.
The U.S. has also participated in bilateral arms reduction agreements with Russia, including the Strategic Arms Reduction Treaty (START) and its successor, New START, which limits deployed strategic warheads. However, the U.S.
maintains its nuclear arsenal as a central component of its national security strategy. U.S. nuclear policy involves balancing multiple objectives: maintaining deterrence against potential adversaries, honoring non-proliferation commitments, and managing relationships with allied nations.
The Department of Defense periodically modernizes nuclear delivery systems and warhead designs to ensure their continued reliability and effectiveness. Current U.S. nuclear policy emphasizes extended deterrence—the commitment to defend allies through the threat of nuclear retaliation—particularly in Europe and East Asia.
