About O.N.E Defense

An American engineering company building autonomous systems for national security.

OUR MISSION

Engineering for the mission.

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.

WHAT WE VALUE

Principles that govern how we build

01

Mission Assurance

Every system is tested to fail safe, perform predictably, and hold up under real operational stress.

02

Accountability

Our command software logs every decision path — auditability is a design requirement, not an afterthought.

03

Speed of Relevance

We iterate our hardware and software fast enough to stay ahead of evolving threats.

WHERE WE STAND

Domestic design. Domestic manufacturing.

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.
