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, held to a strict standard of mission assurance.
We are privately held. Program details are shared with authorized mission partners.
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 engineered and produced in the United States, in support of U.S. national security priorities and allied mission partners.
Founded by a small team of propulsion and guidance engineers to build a faster path from concept to fielded unmanned systems.
Completed first instrumented flight test of the ONE-Vanguard airframe at a U.S. test range.
Started development of the Sentinel command-and-control software to unify sensor and effector data.
Opened our first dedicated production line for ONE-Vanguard airframes and avionics.
ONE-Vanguard reached 12 consecutive successful flight tests; Sentinel C2 entered operational testing.
O.N.E Defense designs, builds, and audits its systems against the frameworks the U.S. government requires of its industrial base.
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.
