Nuclear Weapons: Action Needed to Address the W80-4 Warhead Program's Schedule Constraints, Report to Congressional Committees   [open pdf - 3MB]

From the GAO [Government Accountability Office] Highlights: "To maintain and modernize the U.S. nuclear arsenal, NNSA [National Nuclear Security Administration] and DOD conduct LEPs [life extension program]. In 2014, they began an LEP to produce a warhead, the W80-4, to be carried on the LRSO [long-range standoff] missile. In February 2019, NNSA adopted an FPU delivery date of fiscal year 2025 for the W80-4 LEP, at an estimated cost of about $11.2 billion over the life of the program. The explanatory statement accompanying the 2018 appropriation included a provision for GAO to review the W80-4 LEP. This report examines, among other objectives, (1) the risks NNSA has identified for the W80-4 LEP, and processes it has established to manage them, and (2) the extent to which NNSA's lifecycle cost estimate for the LEP aligned with best practices. GAO reviewed NNSA's risk management database and other program information; visited four NNSA sites; interviewed NNSA and DOD officials; and assessed the program's cost estimate using best practices established in prior GAO work."
