Energy abundance unlocks progress. It powers missions, grows economies, strengthens national security, and expands what’s possible on Earth and beyond. But in the places where power is most critical, it’s often the hardest to deliver. That’s the problem we’re solving.
At Antares, we’re building compact nuclear microreactors to deliver reliable, mobile energy where it’s needed most: remote military bases, austere industrial sites, and, one day, deep space and underwater missions. The U.S. nuclear industry hasn’t seen true momentum in decades. We’re moving it forward with urgency, humility, and a commitment to building what’s needed now.
Our team includes engineers and operators from SpaceX, Relativity Space, Ursa Major, the White House, MIT, Rigetti Computing, and the U.S. Air Force. Backed by over $130M from top-tier investors, we’re focused on shipping hardware not hypotheticals.
