The company said it also broke ground on Building 2 last summer, a structure of more than 924,000 square feet, where crews are now raising walls and preparing for interior construction. Anduril has finalized a full site plan that outlines a staggered, 10-year buildout to bring Arsenal-1 to full scale by 2035.
Under the plan, additional manufacturing and warehouse buildings, a centralized hub, a substation, operations facilities, roadwork, and a campus amenities building will be added over time. Each facility will come online in phases to align production capacity with demand rather than opening all at once.
Anduril said it is working with Pickaway County officials and Ohio state engineers on road and traffic design while expanding engagement with local community partners and schools. The company described these efforts as part of establishing a long-term presence in the region.
The company said it will become a major employer in Ohio, with its first 25 Ohio-based employees hired in July and trained at its California headquarters. Those workers, primarily in technical production and manufacturing roles, have begun returning to Ohio to support full-scale hiring and initial production in Building 1.
More than 50 people were hired for Arsenal-1 in 2025, according to the company, with additional hiring underway for future cohorts. Anduril also announced recent appointments to its Ohio leadership team, including a vice president of production, a director of state and local government relations, and a director of external affairs based in central Ohio.
The first product to be built at Arsenal-1 will be the YFQ-44A, a missionized version of Anduril’s Fury autonomous fighter jet developed for the U.S. Air Force’s Collaborative Combat Aircraft program. The company said it took the aircraft from clean-sheet design to a fully built platform in 365 days, began flight testing in October, and plans to start production in Building 1 by the second quarter.
Anduril said Arsenal-1 is intended to anchor a new model of American defense manufacturing, with multiple programs expected to move to the site over the next 12 months. The company described the project as a long-term investment in U.S. industrial capacity and Ohio’s workforce, with updates to be provided as the facility moves toward initial operations.
