JASON on the Physics of Nuclear Weapons
Despite the extensive data obtained through the conduct of more than 1000 nuclear explosive tests, there is still much that is unknown or imperfectly understood about the science of nuclear weapons.
A newly disclosed report prepared in 2011 by the JASON science advisory panel assessed efforts by the National Nuclear Security Administration (NNSA) to “develop improved understanding of the underlying physics of the materials and components in nuclear weapons.”
The study was released in redacted form last week in response to a Freedom of Information Act request from the Federation of American Scientists. See Hydrodynamic and Nuclear Experiments, JASON report JSR-11-340, November 2011.
More recently, JASON performed “a short study of the science and technology enabling improved measurement, characterization, and understanding of the state of stress in engineered subsurface systems of the Earth’s crust.” See Subsurface Characterization, Jason letter report JSR-14-Task-013, September 2014.
Without information, without factual information, you can’t act. You can’t relate to the world you live in. And so it’s super important for us to be able to monitor what’s happening around the world, analyze the material, and translate it into something that different audiences can understand.
Russia currently maintains nearly 5,460 nuclear warheads, with an estimated 1,718 deployed. This represents a slight decrease in total warheads from previous years but still positions Russia as the world’s largest nuclear power alongside the United States.
Nuclear weapons budgeting is like agreeing to buying a house without knowing the sales price, the mortgage rate, or the monthly payment.
The United States Air Force has forward deployed about one-third of its B-2 stealth bombers to Diego Garcia, or about half the B-2s considered fully operational at any given time.
