Stop Deployment of the New “Low-Yield” Nuclear Warhead Before It’s Too Late

By Monica Montgomery, September 25, 2019


Congress’s window to prevent the deployment of a dangerous new nuclear weapon will soon close.

Right now, the House and Senate are finalizing the 2020 National Defense Authorization Act (NDAA), an annual bill that authorizes U.S. military policies and programs. While the Senate bill would fund the deployment of a new nuclear weapon—the “low-yield” W76-2 warhead for submarine-launched ballistic missiles—the House version would block it. We need the House approach to prevail.

These warheads are so dangerous because they are built to be used. The term “low-yield” is designed to make policymakers think that these nuclear weapons—which are only slightly less destructive than those that devastated Hiroshima and Nagasaki—could be more readily used. Last year, Congress authorized and funded the construction of these warheads. Unless this new Congress acts, these warheads could be deployed sometime this fall.

The persistent advocacy of FCNL advocates and our partners has been crucial as we lobby on this issue. Now Congress stands at a critical juncture in deciding whether to allow or stop this dangerous idea.

Ask your members to urge NDAA negotiators to adopt the House provision blocking these dangerous warheads.

Question & Answer with Anthony Wier

Nuclear weapons — no matter the size — must never be used. This message is at the heart of FCNL’s work to stop the deployment of the so-called low-yield nuclear warheads on U.S. Navy submarines.

Update Nuclear Weapons: Dangerous, Expensive and Immoral 

Written by Deanne Butterfield

On August 6, 1945 the Japanese city of Hiroshima was annihilated in a flash by a single uranium bomb. It razed and burnt 70 percent of all buildings, killed an estimated 140,000 Japanese civilians and Korean laborers, irradiated the soil and plants, and brought increased rates of cancer and chronic disease among the survivors. A slightly larger plutonium bomb exploded over Nagasaki three days later, levelling the city and killing another 74,000.
