Summary

Certain military leaders must do a full check every two years on the safety, security, reliability, long‑term sustainment, performance, and military usefulness of nuclear weapon delivery types and the nuclear command and control system. By December 1 of each even‑numbered year, each leader must send a report to the Secretary of Defense and the Nuclear Weapons Council that gives the assessment results, points out any gaps or shortfalls, describes risks to missions or capabilities, notes anything that made the assessment less accurate, and—if the Commander of U.S. Strategic Command finds a delivery‑platform problem—discusses other platform types or fixes that could do the job. By March 1 after those December reports, the Secretary of Defense must give the reports to the President, along with any comments, conclusions, or other material the Secretary wants to add. By March 15, the President must send that package to the congressional defense committees. The Secretary may make the report classified if needed. Covered officials are the Commander of U.S. Strategic Command; the Navy’s Director of the Strategic Systems Program; the Air Force’s Commander of Global Strike Command; and the Commander of U.S. Air Forces in Europe.
