Anduril Arsenal-2 Plant Gets $2.9B Navy Contract; U.S. Takes 40% Equity Stake in $6.6B Submarine Component Yard

Anduril announced a $6.6 billion submarine component facility at Sparrows Point, Maryland (Arsenal-2), funded by $3.7 billion from Anduril and $2.9 billion Navy contract, with the U.S. government taking a 40 percent equity stake in the subsidiary operating the yard. The plant will produce Virginia-class submarine components including torpedo tubes for delivery to General Dynamics Electric Boat and HII Newport News by 2030.

The government equity stake is the real news here. A 40 percent ownership position in the operating subsidiary means the Navy now bears downside risk if Arsenal-2 fails to meet production targets or faces cost overruns—a structure that mirrors DARPA-backed manufacturing plays more than traditional prime contracts.

This inverts the usual risk allocation and suggests the Navy views component supply as so critical that it will co-own the solution rather than simply purchase output. Electric Boat and Newport News lose exclusivity on component sourcing, which erodes their margin on subassemblies but forces them to focus capital on final integration—a reallocation that favors yards with existing infrastructure.

WHY IT MATTERS

General Dynamics and HII now have a third-party supplier for critical bottleneck components, which forces both primes to restructure their production schedules and shifts capacity constraints from component fabrication to final assembly—the constraint that has capped Virginia-class production at 1.3 hulls per year.

The 40 percent government equity stake signals the Navy's willingness to absorb balance-sheet risk on non-traditional suppliers, a precedent that reshapes how future industrial base investments get capitalized. Watch whether the FY27 FYDP reflects accelerated Virginia-class delivery dates; if Arsenal-2 hits its 2030 timeline and delivers at rated capacity, the Navy could compress the current 10-year backlog by 18-24 months.

WHAT THIS DOESN’T TELL US

What is Anduril's actual production capacity target for torpedo tubes and other components, and does the $2.9 billion contract value cover full capacity utilization or a portion of Arsenal-2's output?
