In a recent article, Jeffrey Lewis of Arms Control Wonk outlined what could happen to U.S. nuclear forces under a sequestration budget. He illustrates that even with Secretary of Defense Leon Panetta’s so-called “doomsday” cuts to nuclear weapons related activities, the U.S. could still field enough warheads to greatly surpass the limits put in place by New START.

What could that “doomsday” look like if the U.S. maximized its nuclear forces? (View at full size)

Whether it came from accident or malice, the likely consequences of any nuclear attack are difficult to fully comprehend. Billions – maybe trillions – of dollars in damage would result, perhaps tens of thousands of lives would be lost with even more injured or sick, not to mention supply lines cut off and massive panic across the nation.

In a nation that spends billions of dollars on insurance each year for natural catastrophes from fires and earthquakes to flooding, one would assume that preparing for a man-made disaster of nuclear proportions would be high up on our list of budget priorities. Sadly, this is not the case.

The U.S. currently possesses nearly half of the world’s nuclear warheads. Each warhead type has its own story and takes its own path through the system. All of these warheads are born in the Department of Energy (DoE) and then reside with the Department of Defense (DoD). Many warheads eventually return to the DoE for dismantlement but some become “trapped” in the DoD through a seemingly endless cycle of upgrades, redeployments or storage in the stockpile.

Below is an attempt to trace the path a warhead may take as it moves through the phases of its life-cycle (full view).

According to the most reliable estimates the U.S. still has over 8,000 nuclear weapons.
