Sentinel ICBM (LGM-35A, formerly GBSD) — Northrop $140.9B Program
nodeNations & Geopolitics · Defense & Military-Industrial
A single company won a $141 billion no-bid deal for new nuclear missiles, and the cost overruns only made it richer.
Who they are
The Sentinel ICBM (LGM-35A), Northrop Grumman's next-generation US land-based nuclear missile replacing the Minuteman III.
What they do
The engine treats it as the largest single-company concentration of nuclear-missile money in US history.
How it works
Boeing dropped out in September 2020, leaving Northrop as sole source with a $13.3B development contract; by a July 2024 Pentagon review the total cost had ballooned to $140.9 billion, an 81% jump, with years of delays blamed on staffing, security clearances, IT, and supply-chain problems. The money is locked in across the program's life into the 2070s.
Why it matters
It shows an architecture built to soak up capital no matter the threat level — where cost overruns become a feature, since the contractor ends up with 81% more money than first agreed.
The engine's record — word for word
Report #87. **Northrop Grumman sole-source contract** for next-generation US land-based ICBM, replacing the Minuteman III. Originally Ground Based Strategic Deterrent (GBSD), renamed LGM-35A Sentinel. **Sept 2020:** Boeing withdrew from competition; Northrop awarded $13.3B Engineering and Manufacturing Development contract. **July 2024 Nunn-McCurdy review** by Under Secretary William LaPlante: program acquisition cost ESCALATED to **$140.9 billion (81% increase from Milestone B baseline)**, schedule slipped 'several years' past the projected 2029 IOC. Per CRS Defense Primer + GAO June 2023 evaluation: program delayed by Northrop staffing shortfalls, clearance delays, IT infrastructure challenges, supply chain disruptions. First Sentinel launch projected 2027, IOC early 2030s. **Engine framing:** $140.9B sole-source flow to a single prime over the program lifecycle, locked in through the 2070s — the single largest concentration of single-prime ICBM capital in US history. Validates H6 money-flow continuity at the Genesis-era apex: the architecture is engineered to absorb capital irrespective of geopolitical threat environment, with cost overruns becoming features rather than bugs (Northrop receives 81% more capital than originally contracted).
