DoD Advances Sentinel Program Despite Overruns

Despite daunting financial and scheduling challenges, the Sentinel ballistic missile program is moving forward, as confirmed by official announcements made on July 8. The Secretary of Defense for Acquisitions, William LaPlante, assured that the Sentinel met the legal prerequisites needed for continuation, following a thorough review stimulated by a substantial Nunn-McCurdy breach earlier in the year. The breach was activated when the monetary commitments associated with the project moved beyond the primary prediction by exceeding 25%. The Sentinel project is directed at substituting the superannuated Minuteman III ICBMs, an integral portion of the U.S. nuclear triad. The program's acquisition costs are evaluated to reach $140.9 billion.

Rising Costs and Program Delays

Touted as an essential modernization effort, the Sentinel program is paramount for maintaining the nuclear triad, despite awareness of the rising costs and delayed execution. Expert prime contractor Northrop Grumman leads the project that has elicited concern from legislators due to spiraling expenses. Prices per unit escalated from an initially proposed $118 million to an unprecedented $162 million - a hike of 37%. The expected total cost for the next ten years rose from $96 billion to nearly $120 billion, with the newest estimate placing it at a substantial $140 billion.

Analyzing Factors Behind Cost Escalation

The program schedule has been pushed back considerably, with the onset of operational capability speculated to be in the early 2030s. The probe identified the command and launch segment as the predominant source of cost growth, encompassing launch centers, launch facilities, and the transformation from Minuteman III to Sentinel. Numerous converging factors account for the cost escalation, including design modifications mandated by the Air Force, an underestimation of the complexities surrounding infrastructural work, and economic realities like increased construction costs and a lack of sufficient labor. Additionally, longer lead times for missile guidance system components have exacerbated the situation.
