Summary

Requires reports and briefings to Congress at key points in the W93 weapon program. After the phase 1 concept study, the Nuclear Weapons Council must send a report that explains likely military traits, how the weapon would be used from stockpile to target, early needs for the nuclear security enterprise (workforce changes, added design/production capabilities, or facility upgrades/new construction), and preliminary schedule and any safety or surety issues that could raise design complexity or cost uncertainty, including dates for first production unit, initial operational capability, and full operational capability. Within 15 days after phase 2 approval, the Administrator must brief Congress on a plan for independent peer review or an expert board for nonnuclear parts, subsystem design, and engineering. That review must use federal, industry, and university expertise and support the whole development life cycle. Within 15 days after phase 3 approval, the Administrator must brief Congress and certify that phases 1–5 will use at least the same best practices and provide the same program visibility as the phase 6.X life‑extension process, and that the design fits estimated schedule and cost goals. The Commander of U.S. Strategic Command must report or brief Congress on SSBN weapon quantity and type needs for the 15 years after the report, including planned life extensions, retirements, or changes. These reporting rules can be waived during a war declared by Congress after January 1, 2021. The term "joint nuclear weapons life cycle" is defined in section 6131.

(a)(1)Upon receiving a concept definition study under phase 1 of the joint nuclear weapons life cycle for the W93 nuclear weapon, the Nuclear Weapons Council shall submit to the congressional defense committees a report that includes the following:

(A)A description of the potential military characteristics of the weapon.

(B)A description of the stockpile-to-target sequence requirements of the weapon.

(C)An initial assessment of the requirements a W93 nuclear weapon program is likely to generate for the nuclear security enterprise, including—

(i)adjustments to the size and composition of the workforce;

(ii)additions to existing weapon design and production capabilities; or

(iii)additional facility recapitalization or new construction.

(D)A preliminary description of other significant requirements for a W93 nuclear weapon program, including—

(i)first production unit date;

(ii)initial operational capability date;

(iii)full operational capability date; and

(iv)any unique safety and surety requirements that could increase design complexity or cost estimate uncertainty.

(2)(A)Not later than 15 days after the date on which the Nuclear Weapons Council approves phase 2 of the joint nuclear weapons life cycle for the W93 nuclear weapon, the Administrator shall provide to the congressional defense committees a briefing on a plan to implement a process of independent peer review or review by a board of experts, or both, with respect to—

(i)the nonnuclear components of the weapon;

(ii)subsystem design; and

(iii)engineering aspects of the weapon.

(B)The Administrator shall ensure that the process required by subparagraph (A)—

(i)uses—

(I)all relevant capabilities of the Federal Government, the defense industrial base, and institutions of higher education; and

(II)other capabilities that the Administrator determines necessary; and

(ii)informs the entire development life cycle of the W93 nuclear weapon.

(b)Not later than 15 days after the date on which the Nuclear Weapons Council approves phase 3 of the joint nuclear weapons life cycle for the W93 nuclear weapon—

(1)the administrator shall provide to the congressional defense committees a briefing that includes certifications that—

(A)phases 1 through 5 of the joint nuclear weapons life cycle for the weapon will employ, at a minimum, the same best practices and will provide Congress with the same level of programmatic insight as exists under the phase 6.X process for life extension programs; and

(B)the proposed design for the weapon can be carried out within estimated schedule and cost objectives; and

(2)the Commander of the United States Strategic Command shall submit to the congressional defense committees a report containing, or provide to such committees a briefing on, the requirements for weapon quantity and composition by type for the sub-surface ballistic nuclear (SSBN) force, including such requirements planned for the 15-year period following the date of the report or briefing, as the case may be, including any planned life extensions, retirements, or alterations.

(c)Subsections (a) and (b) may be waived during a period of war declared by Congress after January 1, 2021.

(d)In this section, the term “joint nuclear weapons life cycle” has the meaning given that term in section 6131.
