Title 10 — Armed Forces
Part VI · Chapter 602 — Nuclear Weapons Stockpile Matters
§ 6131. Stockpile responsiveness program
Statutory text
Statement of Policy.—
It is the policy of the United States to identify, sustain, enhance, integrate, and continually exercise all capabilities required to conceptualize, study, design, develop, engineer, certify, produce, and deploy nuclear weapons to ensure the nuclear deterrent of the United States remains safe, secure, reliable, credible, and responsive.
Program Required.—
The Secretary of Energy, acting through the Administrator and in consultation with the Secretary of Defense, shall carry out a stockpile responsiveness program, along with the stockpile stewardship program under section 6111 and the stockpile management program under section 6116, to identify, sustain, enhance, integrate, and continually exercise all capabilities required to conceptualize, study, design, develop, engineer, certify, produce, and deploy nuclear weapons.
Objectives.—
The program under subsection (b) shall have the following objectives:
Identify, sustain, enhance, integrate, and continually exercise all of the capabilities, infrastructure, tools, and technologies across the science, engineering, design, certification, and manufacturing cycle required to carry out all phases of the joint nuclear weapons life cycle process, with respect to both the nuclear security enterprise and relevant elements of the Department of Defense.
Identify, enhance, and transfer knowledge, skills, and direct experience with respect to all phases of the joint nuclear weapons life cycle process from one generation of nuclear weapon designers and engineers to the following generation.
Continually demonstrate stockpile responsiveness throughout the range of capabilities as required, such as through the use of prototypes, flight testing, integrated system demonstrations, and development of plans for certification without the need for nuclear explosive testing.
Develop technologies for transition to a nuclear stockpile life extension program or new nuclear weapon program project that have the potential to reduce design, certification, and manufacturing cycles cost and schedule.
Continually exercise processes for the integration and coordination of all relevant elements and processes of the Administration and the Department of Defense required to ensure stockpile responsiveness.
The retention of the ability, in coordination with the Director of National Intelligence, to assess and develop prototype nuclear weapons of foreign countries if needed to meet intelligence requirements and, if necessary, to conduct no-yield testing of those prototypes.
Joint Nuclear Weapons Life Cycle Process Defined.—
In this section, the term “joint nuclear weapons life cycle process” means the process developed and maintained by the Secretary of Defense and the Secretary of Energy for the development, production, maintenance, and retirement of nuclear weapons.
