Bawden, Director Natural Resources and Environment, Testimony Before the Subcommittee on Strategic Forces, Committee on Armed Services, House of Representatives [open pdf - 414KB]
From the GAO [Government Accountability Office] Highlights: "NNSA [National Nuclear Security Administration] is simultaneously modernizing the nation's nuclear weapon stockpile and the infrastructure on which weapon programs depend. In a 2019 report, NNSA stated that this is the busiest time for the nuclear security enterprise since the Cold War era. GAO's April 2017 review of NNSA nuclear modernization programs concluded that NNSA made optimistic assumptions about future costs. DOD and DOE [Department of Energy] estimate that nuclear modernization will cost hundreds of billions of dollars over the next decade. This statement is based on 18 GAO reports issued from July 2003 to February 2020 and selected updates. It discusses (1) NNSA's ongoing and planned programs and projects to modernize weapons and related infrastructure and challenges they present; (2) NNSA's improvements in managing these programs and projects, and additional steps NNSA could take to make further improvements; and (3) GAO's prior recommendation to NNSA on assessing the affordability of its portfolio of modernization programs."
