Anduril Industries said today the first products to come from its Arsenal-1 plant in Ohio will be prototypes of the company’s YFQ-44A Fury unmanned fighter jet. Costa Mesa-based Anduril gave an update a year after announcing the mega-factory. “Construction on Building 1 is well underway and will encompass 775,000 square feet of production space and 120,000 additional square feet of office and support space. Today, crews are raising the walls and will start internal construction soon,” Anduril said in a statement on its website today. Anduril also expressed its “long-term commitment” to the region where Arsenal-1 is located.
