Anduril announced it is building their massive weapons factory, Arsenal-1, in Columbus, Ohio, confirming TechCrunch’s earlier reporting.

The company said its Columbus plant could eventually produce tens of thousands of autonomous systems and weapons each year.

Anduril, a defense and aerospace contractor, has selected a site in Columbus for Arsenal-1, the company’s first hyperscale weapons manufacturing facility. The Southern California-based firm plans to invest approximately $1 billion of its own capital into the development.
