An American engineering company building autonomous systems for national security.
O.N.E Defense builds unmanned strike systems, sensing networks and command software for the United States and its allies, with mission assurance as a design goal.
We are a privately held company, founded in October 2026.
Every system is tested to fail safe, perform predictably, and hold up under real operational stress.
Our command software logs every decision path — auditability is a design requirement, not an afterthought.
We iterate our hardware and software fast enough to stay ahead of evolving threats.
O.N.E Defense airframes, avionics, and software are designed to support U.S. national security priorities.
O.N.E Defense was founded to build unmanned strike, layered defense and command software for U.S. national security.
We design and manufacture unmanned aircraft, rocket systems, precision armaments and air defense, plus the Sentinel software that ties them together. In short, the hardware and the software that connects it.
