The Air Force has begun construction of a new underground nuclear weapons storage and handling facility at F.E. Warren Air Force Base in Cheyenne, Wyoming.
The new Weapons Storage and Maintenance Facility (WSMF; sometimes called Weapons Generation Facility), which will replace the current Weapons Storage Area (WSA), will be a 90,000-square-foot reinforced concrete and earth-covered facility with supporting surface structures.
A satellite image taken in August and obtained from Maxar shows construction is well underway of the underground facility as well as several supporting facilities.
The Air Force says the new facility “will provide a safer and more secure facility for the storage of U. S. Air Force (USAF) assets,” a reference to W78/Mk12A and W87/Mk21 warheads for the Minuteman III ICBMs deployed in Warren AFB’s 150 missile silos. In the future, if Congress agrees to fund it, the new W87-1 warhead will replace the W78. According to the Air Force:
“The primary interior walls of Maintenance and Storage Area are 4-foot thick reinforced concrete (RC) elements with 4-foot thick RC roof slabs. The primary wall and roof elements are surrounded by a 20-foot thick soil layer which is contained by a 3-foot thick RC wall and roof element layer. The heavy multilayered system sits on a 5-foot thick RC structural mat for support.”
The $144 million contract was awarded to Fluor Corporation by the U.S. Army Corps of Engineers in 2018. The ground-breaking ceremony took place on May 21, 2019 but substantial construction (of buildings) did not begin until the Spring of 2020. The president of Flour’s Government Group is Tom D’Agostino, who previously served as the undersecretary for nuclear security at the Department of Energy, administrator of the National Nuclear Security Administration (NNSA), and deputy administrator for defense programs. Construction was scheduled to take 40 months and be completed in 2022.
Construction of the underground storage facility at F.E. Warren AFB follows the completion in 2012 of a massive underground nuclear weapons storage facility at the Strategic Weapons Facility Pacific (SWFPAC) next to the Kitsap Naval Submarine Base. Underground storage facilities are also planned at other bases.
To empower new voices to start their career in nuclear weapons studies, the Federation of American Scientists launched the New Voices on Nuclear Weapons Fellowship. Here’s what our inaugural cohort accomplished.
The FAS Nuclear Notebook is one of the most widely sourced reference materials worldwide for reliable information about the status of nuclear weapons and has been published in the Bulletin of the Atomic Scientists since 1987. The Nuclear Notebook is researched and written by the staff of the Federation of American Scientists’ Nuclear Information Project: Director Hans […]
