Anduril, the defense tech company that makes artificial-intelligence-backed weapons, said on Wednesday that it had raised $5 billion in new funding, as modernizing the U.S. military has become a priority for the Trump administration. The financing values Anduril at $61 billion, double the $30.5 billion that it was valued at in June in its last funding round. The latest fund-raising was led by the longtime investors Thrive Capital and Andreessen Horowitz amid talk that Anduril could try to go public in the next year. In total, the company has raised $6.82 billion through eight funding rounds from investors including Founders Fund and Lux Capital. Anduril has established itself as a top player among U.S. defense companies. Founded by the tech entrepreneur Palmer Luckey and others in 2017, the company has developed autonomous submarines and jets, weaponized drones and augmented reality helmets for the military. The firm, based south of Los Angeles, has said it wants to remake American national defense. In its early years, Anduril created border surveillance software for the U.S. government before expanding into other products. When Russia invaded Ukraine in 2022, the company began testing A.I.-backed drones on the battlefield and has since developed a range of pilotless aircraft. In March, Anduril signed a 10-year, $20 billion deal with the Army for some of its software products and A.I.-backed weapons. That same month, the company announced that it was part of a consortium of companies building a $185 billion space-interceptor missile system for the U.S. government, which is known as Golden Dome. In a letter on Wednesday, Brian Schimpf, Anduril’s chief executive, said the company had more than doubled its revenue to $2.2 billion in 2025. Anduril “nearly doubled our work force, won and delivered on our first international program of record to the Royal Australian Navy and demonstrated autonomous flight on an Air Force unmanned combat aircraft program, among many other milestones,” Mr. Schimpf said. The company also opened a $1 billion factory in Ohio to speed production of its weapons systems. “The convergence of artificial intelligence, autonomy and advanced sensing is reshaping warfare,” Mr. Schimpf said.

Future spacecraft could use a single propellant to perform both rapid movements and slow, highly controlled adjustments.
