Hadrian, the factory builder and defense manufacturer, raised $1.37 billion in venture capital and is now valued just shy of $8 billion.Why it matters: American reindustrialization is catching on beyond niche national-security and investor communities.What they're saying: "We were early," chief executive Chris Power tells Axios. "This has been a five-year slog, and only 18 months ago everyone went, 'Oh, God, manufacturing is super important, and we really need to create new American manufacturing jobs fast.'"How it works: Hadrian pumps out precision parts and provides factories-as-a-service for aerospace and defense markets. It employs skilled human workers and augments that workforce with artificial intelligence, automation and robotics. (Its proprietary software is known as Opus.)Hadrian today has nearly 3 million square-feet across four sites, and a new headquarters in Los Angeles and an engineering and research-and-development hub in San Francisco are being planned.Zoom in: Hadrian works with the world's largest arms makers, including Lockheed Martin and RTX, as well as neo-primes and smaller outfits, like Anduril Industries.In March, the U.S. Navy said the company would mass-produce components in Alabama for the service's Virginia-class attack and Columbia-class ballistic missile submarines."I think we're far ahead of the pack, in terms of highly automated, design-agnostic factories," Power says.Follow the money: This Series D funding comes a little more than one year after a $260 million Series C.Backers include WCM Investment Management, Washington Harbour Partners, Valor Equity Partners, 137 Ventures and Baillie Gifford.JPMorganChase's Strategic Investment Group served as the anchor co-lead, investing via the firm's Security and Resiliency Initiative.Zoom out: Wars in the Middle East and Eastern Europe have thrust production proficiency and munitions health into the spotlight.U.S. troops overseas are today shooting expensive interceptors and missiles faster than they are being produced at home. (The Pentagon has denied stockpile depletion.)The bottom line: "This is a no-fail mission to make sure that we have the production capability domestically," Power says."Being able to produce — and have advanced factories — is deterrence," he adds. "It was never inventory. It was never a nice design. It's mass, and we need that in place for the next four to 10 years, so that we can continue to lead the world in a rational, democratic way."Go deeper: GM, Lockheed Martin to collaborate on weapons production
