We will address Sentinel’s challenges, identify the best path forward, and do everything possible to emplace Sentinel as soon as we can.
Work to address Sentinel program challenges and emplace Sentinel as soon as possible.

Evidence
The Senate Armed Services Committee said Deb Fischer would chair the Strategic Forces Subcommittee, which has responsibility for nuclear and strategic forces, DOE defense nuclear programs, and missile defense.
The Senate committee-reported bill included a plan to deploy up to 450 Sentinel ICBMs and an alternative acquisition strategy, but the conference agreement did not include that provision; it only required a briefing if a presidential decision is made.
DoD said Sentinel had a critical cost breach, certified the program to continue, rescinded Milestone B, directed the Air Force to restructure the program, estimated total acquisition costs at $140.9 billion, and said a delay of several years was currently estimated.
Air Force testimony said the critical major weapon systems portfolio includes LGM-35A Sentinel and Minuteman III, and that the department is partnering to remove barriers and set conditions for continued program success.
Fischer announced FY2027 NDAA provisions as Strategic Forces Subcommittee chair, including limits pending Minuteman III sustainment strategy and modifications to maximize end-of-life margin.
SASC announced S. 4784, the FY2027 NDAA, had been filed and linked official bill text, executive summary, and report language.
The committee said the Sentinel breach should be addressed while keeping modernization robustly funded and active; it also flagged extended transition sustainment challenges.
S. 4784 would protect ICBM levels while allowing Minuteman III-to-Sentinel transition, authorize $115 million for ICBM parts, and condition funds on a Minuteman sustainment strategy.
The FY2026 NDAA summary says the act fully funds nuclear modernization and authorizes added funding to accelerate Sentinel ICBM modernization.
DoD found a critical Nunn-McCurdy breach, rescinded Milestone B approval, directed restructuring, estimated $140.9 billion acquisition cost, and projected several years of delay.
Assessments
Fischer materially worked on the Sentinel issue during the relevant Senate term, including through Strategic Forces Subcommittee leadership and NDAA provisions aimed at sustaining Minuteman III, funding nuclear modernization, and addressing Sentinel transition and delay risks. However, the core promised outcome of emplacing Sentinel as soon as possible was not delivered: DoD found a critical cost breach, rescinded Milestone B approval, ordered restructuring, and projected years of delay. This supports partial credit for serious same-term legislative and oversight effort, not full delivery.
Fischer had a relevant oversight role as chair of the Senate Armed Services Strategic Forces Subcommittee and appears to have materially supported Senate efforts to address Sentinel acquisition problems, including committee-reported FY25 NDAA language on deployment planning and acquisition strategy. But the stronger Senate provision was not enacted in conference, and the underlying promised outcome was not achieved: DoD reported a critical cost breach, program restructuring, and delays of several years, and Sentinel was still being worked in 2026 rather than emplaced. Under the federal office standard, this is a serious legislative/oversight attempt that still fell short of delivery.
