• •Antares Industries officially reached reactor criticality with its Mark-0 prototype unit.
• •The achievement serves as the foundational milestone for validating the firm's core power generation technology.
• •Technical performance data, thermal output metrics, and safety validation protocols remain undisclosed by the company.

Antares Industries announced the achievement of criticality for its Mark-0 reactor, marking the transition from theoretical design to active testing. Unlike traditional nuclear deployments that span decades of regulatory review, Antares is operating within a private startup framework, mirroring the rapid-iteration approach currently seen in aerospace and fusion development. However, the company has provided limited public data regarding the unit's power density or long-term operational stability. The milestone serves as an initial proof of concept, though the project's viability will ultimately hinge on its ability to scale power output while meeting stringent commercial safety standards.
