United States nuclear forces provide strategic deterrence and warfighting capability through deployed and non-deployed List of United States military bases, delivery systems, and command authorities. They evolved from programs initiated under Manhattan Project and institutionalized during the Cold War against Soviet Union competition, adapting through eras marked by treaties such as the Strategic Arms Reduction Treaty and events like the Cuban Missile Crisis. Oversight involves civilian leadership at The Pentagon and legislative authorization from the United States Congress.

Overview

The force comprises land-based Minuteman III intercontinental ballistic missile units, sea-based Ohio-class submarine-launched ballistic missiles, and air-delivered B-52, B-2, and B-21 Raider nuclear-capable bombers. Agencies and commands include the United States Strategic Command (USSTRATCOM), Air Force Global Strike Command, and Submarine Force Atlantic (COMSUBLANT), coordinated with policy bodies like the National Security Council and offices within the Department of Defense. Funding and acquisition span the Defense Advanced Research Projects Agency, Nuclear Weapons Council, and programs at Los Alamos National Laboratory, Lawrence Livermore National Laboratory, and Sandia National Laboratories.

Nuclear Triad: Land, Sea, Air

Land leg: F.E. Warren Air Force Base, Minot Air Force Base, and Malmstrom Air Force Base host dispersed Minuteman III silos overseen by Air Force Global Strike Command wings. Sea leg: Ohio-class submarine fleets operate from ports like Naval Station Kitsap and Naval Submarine Base Kings Bay under United States Fleet Forces Command and deploy Trident II (D5) missiles with crews trained at Naval Nuclear Power Training Command. Air leg: strategic bombers such as B-52 Stratofortress units at Minot AFB and Barksdale AFB, B-2 Spirit squadrons at Whiteman AFB, and the emerging Northrop Grumman B-21 Raider program project basing and payloads in coordination with Northrop Grumman and Boeing.

Strategic Doctrine and Policy

Policy foundations come from documents like the Nuclear Posture Review and directives from the President of the United States informed by the National Security Council and the Secretary of Defense. Deterrence concepts derive from Cold War-era analyses by scholars associated with RAND Corporation and debates involving figures like Henry Kissinger and Kurt M. Campbell. Declaratory policy has shifted across administrations through incidents including the Cuban Missile Crisis and initiatives like New START negotiations involving the Russian Federation. The United States maintains doctrines of second-strike capability, extended deterrence for allies such as NATO members and treaty partners like Japan and Republic of Korea, and nuclear planning tools developed with inputs from the Joint Chiefs of Staff.

Command, Control, and Operations

Operational command resides with the Commander, United States Strategic Command under civilian direction by the Secretary of Defense and authority of the President of the United States. The command-and-control architecture links facilities such as the Global Operations Center, Offutt Air Force Base, and the National Military Command Center at The Pentagon with resilient systems like Cheyenne Mountain Complex legacy infrastructures and alternate command posts like Raven Rock Mountain Complex. Communications rely on satellites maintained by United States Space Force elements, strategic airborne command posts such as E-4B and E-6B, and protocols developed after incidents like the Able Archer 83 exercise.

Modernization and Force Structure

Modernization programs include the Ground Based Strategic Deterrent to replace Minuteman III, the Columbia-class submarine program to replace Ohio-class submarine vessels, and the B-21 Raider to modernize bomber forces. Warhead life-extension projects are executed by the National Nuclear Security Administration and design centers at Los Alamos National Laboratory, Lawrence Livermore National Laboratory, and Sandia National Laboratories, guided by congressional oversight from committees like the United States House Committee on Armed Services. Industrial partners such as Lockheed Martin, Northrop Grumman, General Dynamics, and Raytheon Technologies provide missiles, propulsion, and avionics. Budget debates intersect with appropriations by the United States Senate Committee on Appropriations and policy reviews by the Office of Management and Budget.

Arms Control, Non-Proliferation, and Treaties

Arms-control history involves the Strategic Arms Limitation Talks, Intermediate-Range Nuclear Forces Treaty, New START Treaty, and multilateral regimes like the Treaty on the Non-Proliferation of Nuclear Weapons. Negotiations engaged diplomats from the United States Department of State and counterparts from the Soviet Union, Russian Federation, United Kingdom, and France alongside forums such as the Conference on Disarmament. Non-proliferation work links to the International Atomic Energy Agency and domestic sanctions authorities like the Treasury Department when addressing proliferation cases involving states such as North Korea and Iran. Legislative measures have included the Atomic Energy Act and oversight by bodies including the Arms Control and International Security Subcommittee.

Accidents, Incidents, and Safety Measures

Historic incidents include the 1961 Goldsboro B-52 crash, the 1966 Palomares B-52 crash, and the 1968 Thule Air Base accident, which informed safety upgrades at Sandia National Laboratories and procedural reforms by the Department of Defense. Security and safety frameworks draw on standards from the Nuclear Regulatory Commission for civilian matters and military directives for nuclear surety, along with incident response mechanisms coordinated with Federal Emergency Management Agency and local authorities such as United States Northern Command liaison units. Continuous improvement efforts stem from investigations by panels like the Robb-Silberman Commission paradigms, testing protocols at sites including Nevada National Security Site, and training regimens at facilities such as Kirtland Air Force Base.
