Stockpile Stewardship and Management Plan

This strategic document is the U.S. Department of Energy National Nuclear Security Administration Fiscal Year 2016 Stockpile Stewardship and Management Plan. It addresses the statutory requirements of Title 50 of the United States Code, Section 2523, and related congressional requests. This fiscal year (FY) 2016 document presents the current detailed plan for maintaining the Nation’s
nuclear weapons stockpile.

The FY 2016 SSMP builds upon last year’s SSMP in balancing NNSA’s investments in maintaining and modernizing the stockpile, revitalizing its physical infrastructure and workforce, and sustaining its research, development, testing, and evaluation programs. The joint DOE and Department of Defense “3+2 Strategy” for stockpile modernization through life extension programs implemented by this SSMP provides the opportunity to continue the Administration’s commitment to maintaining a safe, secure, and effective deterrent while reducing the size of the stockpile.

For example, once the B61-12 life extension program is completed in FY 2025 and confidence is gained in the B61-12 weapons in service, the B83-1, the last megaton-class weapon in America’s nuclear arsenal, will be retired. The combination of these actions will result in a 50 percent reduction in the number of nuclear gravity bombs in the stockpile, the removal of a megaton-class weapon, an 80 percent reduction in amount of special nuclear material in the bomb portion of the air leg, and a reduction in the safety and security risks associated with the stockpile.

Furthermore, consistent with life extension program plans, NNSA’s investments in plutonium will allow war-reserve-quality production of 30 plutonium pits per year by FY 2026 and 50 to 80 pits per year by 2030. Similarly, our Uranium Strategy will allow us to recapitalize critical enriched uranium operations that currently reside in outdated facilities. The plans described in this document for these essential capabilities are consistent with the requirements outlined in the FY 2015 National Defense Authorization Act.

To support this plan, NNSA has, for the sixth consecutive year, increased the budget request for Weapons Activities. If adopted by Congress, this budget request will increase funding by $891 million from the comparable FY 2015 enacted level. Much of this 11.2 percent increase will be devoted to stockpile life extension programs and recapitalization of critical plutonium and uranium capabilities. In addition, the schedule for the W80-4 life extension program has been moved up 2 years, and a conventional high-explosive refresh has been added to the W88 Alteration.

With this plan and the support of Congress, the nuclear deterrent will support the Nation's current and future defense posture while meeting its New Strategic Arms Reduction Treaty agreements and enable progress toward a world without nuclear weapons.
