Chaos Industries acquired Atropos Group, a deal some six months in the making, according to company executives.Why it matters: The takeover expands Chaos' defense-tech offerings, which began with radars and other sensors and have since grown to include interceptors, missiles and now autonomous aircraft."The very few companies that are going to win are going to be really, truly multi-product," CEO John Tenet told Axios."I think there's going to be an opportunity here to pick up a few more companies over the next few years, and there's a lot of thought that goes into it."Driving the news: Atropos co-founder Colin Carroll, formerly of Applied Intuition and Anduril Industries, was named Chaos' chief growth officer. Vince Dutcavich, another co-founder, is leading Chaos' new aerospace division."You'll see the pairing of sensors, effectors and autonomous platforms — this is the future, in my opinion," Carroll told Axios.The focus, he added, is "on very pragmatic weapon systems. So, not the coolest thing. Not the sexiest thing. Not the best-engineered thing. But the shit that actually works."The intrigue: Chaos is rarely in the news despite its equipment being used across Eastern Europe and the Middle East. It's currently pumping out 40 radars a month, with eyes on 100 a month by the end of the summer.Follow the money: Financial details of the acquisition were not disclosed.Chaos was valued north of $4 billion when it raised $510 million in November. It's secured a total of $1 billion, with backers including 8VC, Accel Partners and Valor Equity Partners."We're not raising until we're raising," Tenet said. "There's a lot of inbound, always."What's next: The company is on the hunt for additional manufacturing space. It has hundreds of thousands of square feet in El Segundo, California, at the moment.
