The business of defense, October 6

Anduril's route into Virginia-class submarine construction runs through the two companies already building the boats, General Dynamics Electric Boat and Huntington Ingalls Industries' Newport News Shipbuilding. Its planned shipyard, Arsenal-2, will build "complex components and large scale assemblies" of the submarine and deliver them to both for final assembly. The yard will go up at Tradepoint Atlantic in Baltimore County, Maryland.¹

Anduril's $6.6 billion headline figure combines two kinds of money. One is $3.7 billion of private capital that Anduril is putting behind the yard. The other is a Navy contract that Anduril says is worth up to $2.9 billion, with payments tied "directly to demonstrated production outcomes." Anduril says that structure leaves the company, "not the taxpayer," with "the majority of the execution risk."¹

Permitting and site preparation begin immediately, with construction to start once the necessary approvals are in place. Initial operations are expected in 2030. The submarine work also has a California address: a new 160,000-square-foot facility in Orange County will manufacture Virginia-class components and support prototyping and production of test assets and maritime components, including torpedo tubes.¹

Aventra Defense Systems, founded in 2025, announced a $17.5 million strategic fundraise on Oct. 6 and listed five priorities for the new capital. First is scaling Piranha "from field-evaluation quantities into low-rate initial production," expanding capacity at its Herndon, Va., production facility.¹

CEO Michael Weigand says Aventra took Piranha "from concept to field deployment overseas" in under a year and "secured our first series of delivery contracts." Aventra's announcement names no buyer, contract number or value for them, which leaves a production plan without a named customer.¹

The company calls Piranha its low-cost, balloon-deployed autonomous precision payload system. Weigand says the approach uses high-altitude balloons and stratospheric air currents to carry mass downrange "without burning fuel," at "a fraction of the cost of conventional standoff munitions."¹ Aventra says Piranha went into operator hands in the Army's Arcane Thunder 26 exercise and in closed evaluations, exercises and combat tests with additional U.S., allied and partner units. Across 400 flights, it says, the system demonstrated autonomous stratospheric reentry, long-range glide and precision kinetic and intelligence, surveillance and reconnaissance (ISR) effects.¹

Konvoy, a Denver firm investing out of its $150 million Fund III, led the round. Existing investor Lavrock Ventures participated alongside new investment from Booz Allen Ventures, Sands Capital and Langford Industries, and Western Alliance Bank provided a funding facility.¹

The plans also reach past Piranha. Another priority is to start development of a new, unannounced platform, and the company says the round expands its roadmap with new offerings in long-range strike, one-way attack and ISR markets.¹
