About

Antares is building compact nuclear microreactors to deliver reliable, mobile energy where it’s needed most—remote military bases, austere industrial sites, and eventually deep space and underwater missions. Founded to tackle the challenge of delivering power where it’s hardest to access, the company is driving momentum in a U.S. nuclear industry that hasn’t seen true progress in decades. Backed by over $50M from top-tier investors, Antares brings together talent from SpaceX, Relativity Space, Ursa Major, MIT, the U.S. Air Force, and more, with a focus on shipping hardware—not hypotheticals.
