Los Alamos National Laboratory, New Mexico

LANL was created in 1943 to serve as a secret laboratory dedicated to research, development, and construction of nuclear weapons. Facilities include plutonium and tritium processing plants, an eight megawatt research reactor and various laser and high explosives buildings. Until April 1984, Los Alamos had the capability to fabricate and assemble nuclear weapon test devices.

35.882444, 106.298132°W

Portsmouth Gaseous Diffusion Plant, Ohio

Built for the production of highly enriched uranium to fuel military reactors and nuclear weapons production, it later produced low-enriched uranium to fuel nuclear power plants. Enrichment operations have ceased.

39.110866°N, 82.991796°W

Savannah River Site, South Carolina

Until the early 1990s, production and separation of plutonium and tritium for use in nuclear weapons occurred at Savannah River Site (SRS). Focus is now on waste management and vitrification, and special nuclear material (SNM) storage.

33.205084°N, 81.741543°W

Oak Ridge Reservation, Tennessee

Established as part of the Manhattan Project, the site contained uranium enrichment process equipment and support facilities. ORNL conducts research and development to advance the nation's energy resources. Site of Oak Ridge National Laboratory (ORNL).

35.995508°N, 84.246511°W

Pantex Plant, Texas

Pantex Plant's primary mission is to assemble, disassemble, repair, and retrofit nuclear weapons for the nation's stockpile. They also develop, fabricate, and test explosives and their components for nuclear weapons. Last new nuclear weapon (W88 warhead) assembled on July 31, 1990.

35.315756°N, 101.566887°W

Hanford Reservation, Washington

Established as part of the Manhattan Project, this site had nine plutonium production reactors operating here. Hanford's activities now focus on environmental restoration and waste management. Nearly 80 percent of DOE's inventory of spent fuel is stored here.

46.54465°N, 119.530315°W

Nevada Test Site, Nevada

Established as the on-continent nuclear weapons proving ground, the NTS has seen more than four decades of nuclear weapons testing. The NTS is larger than the state of Rhode Island. The last test occurred in 1992.

37.037366°N, 116.030045°W

Sandia National Laboratories, New Mexico

Responsible for research, development and testing of all non-nuclear components in nuclear weapons; manufactures neutron generators; develops transportation and storage systems for nuclear weapons; assesses nuclear weapons safety, security and control and helps train military personnel in the assembly and maintenance of completed weapons.

35.074684°N, 106.550217°W

Mound Laboratory, Ohio

Until October 1994, produced non-nuclear components of nuclear weapons (e.g., detonators, timers, cable assemblies, pyrotechnic devices). Formerly developed tritium reservoirs; currently analyzes, disassembles, and recovers tritium from weapon components. Until November 30, 1961 Mound fabricated plutonium-beryllium neutron sources.

39.629424°N, 84.287968°W

Pacific Proving Ground

Used for above-ground and underwater testing of 66 nuclear weapons (activities gradually transferred to Nevada Proving Ground during the 1950s). Some sites, notably Bikini Atoll, are still undergoing monitoring and decontamination.

11.5°N, 162.333333°W

Barksdale Air Force Base, Louisiana

Gravity bombs, air-launched cruise missiles and advanced cruise missiles are stored at this site, the Air Force's main base for B-52H bombers.

32.50122°N, 93.669777°W

Whiteman Air Force Base, Missouri

Various gravity bombs, including the B61-7, B83 and the new B61-11 ‘earth penetrator' are stored at this base for B-2 bombers.

38.728577°N, 93.548369°W

Bremerton Naval Submarine Base, Washington

The nuclear submarines based here are armed with Trident II D-5, submarine-launched ballistic missiles.

47.743479°N, 122.731018°W

Kings Bay Naval Submarine Base, Georgia

The nuclear submarines based here are armed with Trident II D-5, submarine-launched ballistic missiles.

30.798917°N, 81.516581°W

Malmstrom Air Force Base, Montana

Minuteman III intercontinental ballistic missiles, with a range of 6,000+ miles, can be launched from 200 silos at this site
