Our CEO, Jordan Bramble, was honored to join the President at the White House today to commemorate the DOE Reactor Pilot Program.

The executive orders were an unlock for advanced nuclear innovation. Antares was first through the door.

On June 4, Mark-0 achieved initial criticality at Idaho National Laboratory — the first privately developed non-light-water reactor to reach criticality in the United States in over four decades.

Speaking at the event, Bramble credited the policy shift that made it possible:

"Mr. President, thank you so much for your leadership. It was really your executive orders that catalyzed this nuclear renaissance. When they first came out, people scoffed. They said it couldn't be done. And now there are not only three, but four companies here that really met the moment.

At Antares, we look forward to being a resilient energy source for Golden Dome, to power high-powered assets in space, and eventually undersea autonomy.

This is a strategic technology for our nation. And what we look forward to doing is putting reactors on our military installations before 2028."

The Reactor Pilot Program was designed to move advanced reactors from paper to hardware on a timeline that matches the urgency of the mission. Mark-0 is what that acceleration looks like in practice: a factory-produced fission microreactor, built for the places where power is hardest to get and matters most.

Criticality was the proof. Deployment is the point.

We look forward to powering our nation's critical missions.
